New data suggest a significantly stronger link in women compared with men between atrial fibrillation (AF) and mild cognitive impairment (MCI) and dementia.

“Our findings imply that women with AF may be at higher risk for MCI and dementia with potentially more rapid disease progression from normal cognition to MCI or dementia than women without AF or men with and without AF,” wrote authors of a new study led by Kathryn A. Wood, PhD, RN, Neil Hodgson Woodruff School of Nursing at Emory University in Atlanta.

The findings were published online in Alzheimer’s & Dementia.

Researchers used the National Alzheimer’s Coordinating Center data with 43,630 patients and analyzed sex differences between men and women with AF and their performance on neuropsychological tests and cognitive disease progression.

Higher odds of dementia, MCI in women

According to the paper, AF is associated with higher odds of dementia (odds ratio [OR], 3.00; 95% confidence interval [CI], 1.22-7.37) in women and MCI in women (OR, 3.43; 95% CI, 1.55-7.55) compared with men.

Women with AF and normal cognition at baseline had a higher risk of disease progression (hazard ratio [HR], 1.26; 95% CI, 1.06-1.50) from normal to MCI and from MCI to vascular dementia (HR, 3.27; 95% CI, 1.89-5.65) than that of men with AF or men and women without AF. 

AF is a major public health problem linked with stroke and heart failure, and is an independent risk factor of increased mortality. It is associated with higher risk of cognitive impairment and dementia independent of stroke history.
 

Cognitive screening for AF patients

The authors wrote that cognitive screening, especially in women, should be part of yearly cardiology visits for patients with AF to help identify early those at highest risk for cognitive disease.

T. Jared Bunch, MD, professor of medicine in the division of cardiovascular medicine at University of Utah in Salt Lake City, said in an interview, “We have learned that how we treat atrial fibrillation can influence risk.”

First, he said, outcomes, including brain health, are better when rhythm control approaches are used within the first year of diagnosis. 

“Restoring a normal heart rhythm improves brain perfusion and cognitive function. Next, aggressive rhythm control – such as catheter ablation – is associated with much lower long-term risks of dementia in the [patients].  Finally, early and effective use of anticoagulation in patients with atrial fibrillation lowers risk of stroke, dementia, and cognitive decline.”
 

Several factors unknown

Dr. Bunch said there are some unknowns in the study, such as how long patients were in atrial fibrillation. 

He said one way to address the inequities is to refer women earlier as women are often referred later in disease to specialty care, which can have consequences.

He said it is not known how many people underwent early and effective rhythm control. 

“Women also are less likely to receive catheter ablation, a cardioversion, or be placed on antiarrhythmic drugs,” said Dr. Bunch, who was not part of the study. “These also represent potential opportunities to improve outcomes by treating the rhythm in a similar and aggressive manner in both men and women.”

Also unknown is how many people were on effective oral anticoagulation, Dr. Bunch noted.

The study importantly highlights a significant problem surrounding the care of women with AF, he said, but there are strategies to improve outcomes.

In addition to earlier screening and referral for women, providers should recognize that men and women may present differently with different AF symptoms. He added that physicians should offer catheter ablation, the most effective treatment, equally to men and women who are candidates.

In all people, he said, it’s important “to start anticoagulation very early in the disease to lower the risk of micro- and macrothrombotic events that lead to poor brain health and function.”

The study authors and Dr. Bunch declared no relevant financial relationships.

CDC signs off on RSV vaccine for older adults

Article Type
Changed
Wed, 07/05/2023 - 13:52

The Centers for Disease Control and Prevention has given a green light to two new vaccines to protect against respiratory syncytial virus, or RSV, in older adults.

CDC Director Rochelle P. Walensky, MD, MPH, agreed with and endorsed the recommendations made earlier by CDC advisors that people age 60 and over may get one of two new vaccines for RSV. Decisions should be made based on discussions with one’s health care provider about whether the vaccine is right for them, the federal health agency said.

The new vaccines, the first licensed in the United States to protect against the respiratory illness, are expected to be available this fall.

On June 21, the CDC’s Advisory Committee on Immunization Practices (ACIP), an independent panel, stopped short of recommending the vaccines for everyone age 65 and above, which was the original question the committee was to consider. The experts amended that question, changing it to whether the panel should recommend the vaccine for those 65 and above if the person and their doctor agreed. The committee voted 9 to 5 in favor.
 

RSV vaccines

RSV leads to 6,000 to 10,000 deaths a year in the United States among those age 65 and older and 60,000 to 160,000 hospitalizations in that group. Seniors and infants are among the most vulnerable to the lower respiratory infection, marked by runny nose, wheezing, sneezing, decreased appetite, and fever.

The FDA in May approved two vaccines — GSK’s Arexvy and Pfizer’s Abrysvo — for adults age 60 and above.

The vote recommending shared decision-making about the vaccine, instead of a routine vaccination recommended for all, “is a weaker recommendation,” said William Schaffner, MD, an infectious disease specialist at Vanderbilt University Medical Center in Nashville and medical director of the National Foundation for Infectious Diseases. Dr. Schaffner is a non-voting member of ACIP. He attended the meeting.

He said the experts voiced concern about a number of issues, including what some saw as a lack of sufficient data from trials on the most vulnerable groups, such as nursing home residents.

Experts also wanted more information about the duration of protection and exactly when a second dose might be needed. At the meeting, a GSK official said its vaccine was 84.6% effective after one and a half seasons, down from 94.1% after one season. A Pfizer official said its vaccine decreased the risk of RSV with three or more symptoms by 78.6% after a season and a half, down from 88.9% after one season.

The panel also wanted more data on whether the RSV vaccines could be administered at the same time as other vaccines recommended for adults.

Both companies gave a range of cost estimates. Pfizer expects its vaccine to cost $180 to $270 but said it could not guarantee that range. GSK said it expects a price of $200 to $295. Under the Inflation Reduction Act, recommended vaccines are covered under Medicare for those with Part D plans, which 51 million of 65 million Medicare patients have. Commercial insurance is likely to cover the vaccines if the CDC recommends them.

SSRI improves cognition, major depression in early dementia

Article Type
Changed
Thu, 06/22/2023 - 15:18

 

TOPLINE:

Vortioxetine significantly improves depressive symptoms, cognitive performance, functioning, and quality of life at 12 weeks in patients with both major depressive disorder (MDD) and early-stage dementia.

METHODOLOGY:

  • The multicenter MEMORY study included 82 subjects with MDD and early-stage dementia, mean age 70.3 years, mostly female (66%) and White (95%).
  • Vortioxetine, a modulator of 5-hydroxytryptamine receptor activity and an inhibitor of the 5-HT transporter, initiated at 5 mg/day (recommended starting dose in older adults) with the dose up-titrated to 10 mg/day after a week and flexible dosing thereafter.
  • Depression was assessed using the Montgomery-Åsberg Depression Rating Scale (MADRS), and cognition with the Digit Symbol Substitution Test (DSST) and Rey Auditory Verbal Learning Test.

TAKEAWAY:

  • There was significant and clinically meaningful improvement in the severity of depressive symptoms, as measured by MADRS total score (the primary outcome), at all assessment time points (P < .0001).
  • Improvements in depressive symptoms were irrespective of dementia type.
  • There were also significant improvements in DSST total score (P < .0001) and in daily functioning and health-related quality of life (HRQoL).
  • Vortioxetine was well tolerated; side effects, including nausea and abdominal pain, were mostly mild to moderate.

IN PRACTICE:

“Vortioxetine demonstrated effectiveness in clinically significantly improving depressive symptoms, cognitive performance, daily and global functioning, and HRQoL in patients with MDD and comorbid early-stage dementia treated for 12 weeks” the researchers noted. 

STUDY DETAILS:

The study was conducted by Michael Cronquist Christensen from pharmaceutical company H. Lundbeck, Valby, Denmark, and colleagues. It was published online in the Journal of Affective Disorders.

LIMITATIONS:

The study is open label and lacked a control group. Learning effects were possible, which could contribute to improved cognitive performance, although significant improvement on the RAVLT was not observed until week 4, suggesting earning effects were minimal.
 

DISCLOSURES:

The study was funded by H. Lundbeck. Mr. Christensen is an employee of H. Lundbeck.

A ‘one-stop shop’: New guidance on hormones and aging

Article Type
Changed
Tue, 06/20/2023 - 18:19

A new statement from the Endocrine Society on hormones and aging highlights the differences between normal aging and disease, and when treatment is and isn’t appropriate.

The idea of the statement “is to be complete, but also to clarify some misunderstandings. ...We tried to be very clear in the language about what we know, where we can go, where we shouldn’t go, and what we still need to learn,” statement coauthor Cynthia A. Stuenkel, MD, of the University of California, San Diego, said in an interview.

Dr. Cynthia Stuenkel

The document is divided into nine parts or axes: growth hormone, adrenal, ovarian, testicular, thyroid, osteoporosis, vitamin D deficiency, type 2 diabetes, and water metabolism. Each section covers natural history and observational data in older individuals, available therapies, clinical trial data on efficacy and safety in older individuals, bulleted “key points,” and research gaps.

“Hormones and Aging: An Endocrine Society Scientific Statement” was presented at the annual meeting of the Endocrine Society and published online in the Journal of Clinical Endocrinology & Metabolism.

During a press briefing, writing group chair Anne R. Cappola, MD, of the University of Pennsylvania, Philadelphia, said the goal is to “provide a really concise summary across each of these areas. ... There are multiple hormonal changes that occur with age, so we really couldn’t limit ourselves to just one gland or the few that we commonly think about. We wanted to cover all the axes.”

The statement tackles several controversial areas, including hormone therapy for menopausal symptoms in women and hypogonadal symptoms in men, diabetes treatment goals in older adults, distinguishing between age-associated changes in thyroid function and early hypothyroidism, and vitamin D supplementation in older adults.

“Hormones have these almost mythical qualities to some people. ... ‘If I just had my hormones back the way they were, it would all work out.’ What we want to do is make sure that patients are being treated appropriately and that their symptoms are being heard and managed and ascribed to the appropriate problems and not necessarily to hormonal problems when they are not. ... Part of what we need to do is [provide] the evidence that we have, which includes evidence of when not to prescribe as well as [when] to prescribe,” Dr. Cappola said.
 

Not designed to be read all at once

In the menopause section, for example, one “key point” is that menopausal symptoms are common, vary in degree and bother, and can be effectively treated with a variety of therapies proven effective in randomized clinical trials. Another key point is that menopausal hormone therapy is safest for women who are younger than 60 years and less than 10 years since starting menopause.

“It’s almost 20 years since the original Women’s Health Initiative, and that led to an incredible falloff of prescribing hormone therapy and a falloff in teaching of our students, residents, fellows, and practitioners about [menopausal] hormone therapy. ... Hopefully, by issuing this kind of aging statement it gets people to read, think, and learn more. And, hopefully, we can improve the education of physicians. ... Menopause is a universal experience. Clinicians should know about it,” noted Dr. Stuenkel, who chaired the menopause section writing panel.

In the type 2 diabetes section, in the bullet points it is noted that oral glucose tolerance testing may reveal abnormal glucose status in older adults that are not picked up with hemoglobin A1c or fasting glucose levels and that glycemic targets should be individualized.

Asked to comment on the statement, Michele Bellantoni, MD, said: “This was a huge undertaking because there are so many areas of expertise here. I thought they did a very good job of reviewing the literature and showing each of the different hormonal axes. ... It’s a good go-to review.”  

“I thought it was a very good attempt to catalog and provide opportunities for policy, and particularly at [the National Institutes of Health], as they look at funding to show where are these gaps and to support appropriate research. I think the most important aspect to come of this is identifying research gaps for funding opportunities. I very much support that,” noted Dr. Bellantoni, who is clinical director of the division of geriatric medicine at Johns Hopkins University, Baltimore.

However, she also said that the 40-page document might be a bit much for busy clinicians, despite the bullet points at the end of each section.

“I would love to see an editorial that puts into perspective the take-home messages or a subsequent article that distills this into every day practice of care of older adults, both preventative and treatment care. ... I think that would be so useful.”

During the briefing, Dr. Cappola noted that the document need not be read all at once.

“It ended up being a large document, but you should not be intimidated by it because each section is only about 2,000 words. So, it’s really a kind of one-stop shop to be able to look across all these axes at once.

A new statement from the Endocrine Society on hormones and aging highlights the differences between normal aging and disease, and when treatment is and isn’t appropriate.

The idea of the statement “is to be complete, but also to clarify some misunderstandings. ...We tried to be very clear in the language about what we know, where we can go, where we shouldn’t go, and what we still need to learn,” statement coauthor Cynthia A. Stuenkel, MD, of the University of California, San Diego, said in an interview.

Dr. Cynthia Stuenkel

The document is divided into nine parts or axes: growth hormone, adrenal, ovarian, testicular, thyroid, osteoporosis, vitamin D deficiency, type 2 diabetes, and water metabolism. Each section covers natural history and observational data in older individuals, available therapies, clinical trial data on efficacy and safety in older individuals, bulleted “key points,” and research gaps.

“Hormones and Aging: An Endocrine Society Scientific Statement” was presented at the annual meeting of the Endocrine Society and published online in the Journal of Clinical Endocrinology & Metabolism.

During a press briefing, writing group chair Anne R. Cappola, MD, of the University of Pennsylvania, Philadelphia, said the goal is to “provide a really concise summary across each of these areas. ... There are multiple hormonal changes that occur with age, so we really couldn’t limit ourselves to just one gland or the few that we commonly think about. We wanted to cover all the axes.”

The statement tackles several controversial areas, including hormone therapy for menopausal symptoms in women and hypogonadal symptoms in men, diabetes treatment goals in older adults, distinguishing between age-associated changes in thyroid function and early hypothyroidism, and vitamin D supplementation in older adults.

“Hormones have these almost mythical qualities to some people. ... ‘If I just had my hormones back the way they were, it would all work out.’ What we want to do is make sure that patients are being treated appropriately and that their symptoms are being heard and managed and ascribed to the appropriate problems and not necessarily to hormonal problems when they are not. ... Part of what we need to do is [provide] the evidence that we have, which includes evidence of when not to prescribe as well as [when] to prescribe,” Dr. Cappola said.
 

Not designed to be read all at once

In the menopause section, for example, one “key point” is that menopausal symptoms are common, vary in degree and bother, and can be effectively treated with a variety of therapies proven effective in randomized clinical trials. Another key point is that menopausal hormone therapy is safest for women who are younger than 60 years and less than 10 years since starting menopause.

“It’s almost 20 years since the original Women’s Health Initiative, and that led to an incredible falloff of prescribing hormone therapy and a falloff in teaching of our students, residents, fellows, and practitioners about [menopausal] hormone therapy. ... Hopefully, by issuing this kind of aging statement it gets people to read, think, and learn more. And, hopefully, we can improve the education of physicians. ... Menopause is a universal experience. Clinicians should know about it,” noted Dr. Stuenkel, who chaired the menopause section writing panel.

In the type 2 diabetes section, in the bullet points it is noted that oral glucose tolerance testing may reveal abnormal glucose status in older adults that are not picked up with hemoglobin A1c or fasting glucose levels and that glycemic targets should be individualized.

Asked to comment on the statement, Michele Bellantoni, MD, said: “This was a huge undertaking because there are so many areas of expertise here. I thought they did a very good job of reviewing the literature and showing each of the different hormonal axes. ... It’s a good go-to review.”  

“I thought it was a very good attempt to catalog and provide opportunities for policy, and particularly at [the National Institutes of Health], as they look at funding to show where are these gaps and to support appropriate research. I think the most important aspect to come of this is identifying research gaps for funding opportunities. I very much support that,” noted Dr. Bellantoni, who is clinical director of the division of geriatric medicine at Johns Hopkins University, Baltimore.

However, she also said that the 40-page document might be a bit much for busy clinicians, despite the bullet points at the end of each section.

“I would love to see an editorial that puts into perspective the take-home messages or a subsequent article that distills this into every day practice of care of older adults, both preventative and treatment care. ... I think that would be so useful.”

Altered gut bacteria a biomarker of preclinical Alzheimer’s?

Article Type
Changed
Tue, 06/20/2023 - 10:13

The composition of gut bacteria in people with preclinical Alzheimer’s disease (AD) differs from that of healthy people, a new study shows.

The findings open up the possibility of analyzing the gut microbiome to identify individuals at a higher risk for dementia and perhaps designing microbiome-altering preventive treatments to help stave off cognitive decline, researchers noted.

Study investigator Gautam Dantas, PhD, cautioned that it’s not known whether the gut is influencing the brain, or the brain is influencing the gut, “but this association is valuable to know in either case.

“It could be that the changes in the gut microbiome are just a readout of pathological changes in the brain. The other alternative is that the gut microbiome is contributing to AD, in which case, altering the gut microbiome with probiotics or fecal transfers might help change the course of the disease,” Dr. Dantas, Washington University, St. Louis, said in a news release.

The study was published online in Science Translational Medicine.
 

Stool test?

Multiple lines of evidence suggest a role for gut microbes in the evolution of AD pathogenesis. However, less is known about gut microbiome changes in the preclinical (presymptomatic) phase of AD.

To investigate, Dr. Dantas and colleagues studied 164 cognitively normal adults, 49 of whom had biomarker evidence of preclinical AD.

After the researchers accounted for clinical covariates and diet, those with preclinical AD had distinct gut microbial taxonomic profiles compared with their healthy controls.

The observed microbiome features correlated with amyloid and tau but not neurodegeneration biomarkers, “suggesting that the gut microbial community changes early in the disease process,” the researchers suggested.

They identified specific taxa that were associated with preclinical AD and including these microbiome features improved the accuracy, sensitivity, and specificity of machine learning classifiers for predicting preclinical AD status.

The findings suggest “markers in the stool might complement early screening measures for preclinical AD,” the researchers noted.

“The nice thing about using the gut microbiome as a screening tool is its simplicity and ease,” Beau Ances, MD, PhD, professor of neurology, at Washington University, St. Louis, said in the release.

“One day, individuals may be able to provide a stool sample and find out if they are at increased risk for developing AD. It would be much easier and less invasive and more accessible for a large proportion of the population, especially underrepresented groups, compared to brain scans or spinal taps,” Dr. Ances added.

The researchers have launched a 5-year follow-up study designed to help determine whether the differences in the gut microbiome are a cause or a result of the brain changes seen in early AD.
 

Caveats, cautionary notes

In a comment, Claire Sexton, DPhil, Alzheimer’s Association senior director of scientific programs and outreach, cautioned that the study design means that it’s “not possible to prove one thing causes another. What it can show is that two or more aspects are in some way related, thus setting the stage for further research.”

Dr. Sexton noted that though the authors accounted for a number of variables in their models, including age, sex, race, education, body mass index, hypertension, and diabetes, and observed no differences in intake of any major nutrient group, “it’s still not possible to rule out that additional factors beyond the variations in gut microbiome contributed to the changes in brain markers of Alzheimer’s.”

Dr. Sexton also noted that the study population is not representative of all people living with AD, with the vast majority of those with preclinical AD in the study being White.

“If these findings are replicated and confirmed in study groups that are representative of our communities, it is possible that gut microbiome signatures could be a further addition to the suite of diagnostic tools employed in certain settings,” Dr. Sexton said.

This research was supported by the Infection Disease Society of America Foundation, the National Institute on Aging, the Brennan Fund and the Paula and Rodger Riney Foundation. Dr. Dantas, Dr. Ances and Dr. Sexton have no relevant disclosures.

‘Deprescribing’: Should some older adults shed their meds?

Article Type
Changed
Tue, 06/20/2023 - 10:14

Joanne Lynn, MD, has lost track of the number of times in her 40 years as a geriatrician she’s seen a new patient come to her office carrying a bucket full of prescription medications – many of which they don’t need.

Dr. Lynn, who is on the faculty of George Washington University,Washington, recalled one woman who unwittingly was taking two blood pressure medications with different names.

“The risks included all the side effects overdosing carries,” Dr. Lynn said, ranging from blurred vision and crankiness to organ failure and even death.

For doctors with patients who don’t know they’re taking too much of a medication, “you wonder whether the drug is causing the health problems, and it’s a symptom of the wrong medication,” rather than a symptom of an undiagnosed illness, she said.

Many adults over age 65 with chronic conditions may be on too many medications and could benefit from a medication review with their primary care doctor. Patients often assume their health providers check for drug interactions or assess if a medication is no longer needed, and will catch extra prescriptions. That could be a risky assumption. Some doctors may prescribe yet another prescription to manage the side effects of an unnecessary drug, instead of doing a medication review and potentially “deprescribing” or discontinuing, a treatment that’s no longer needed.

About 57% of people age 65 years or older take five or more medications regularly – a concept known as polypharmacy, a study published in 2020 in the Journal of the American Geriatrics Society shows. While doctors prescribe drugs to help patients manage various ailments, as a list of medications grows, so do potential complications.

An older adult might forget to tell their doctor what they’re taking, or maybe they don’t even know what they’re taking or why, Dr. Lynn said.

“In some cases, a doctor just added a drug to treat something, not realizing they were already taking something else for it,” she said. “Of course, the situation of whether these patients can even afford all these drugs matters a lot, too.”

Some older adults may pick and choose which medications to take based on cost, not knowing which prescriptions are necessary, Dr. Lynn said.
 

Finding the ‘right balance’

Indeed, if given the option, up to 80% of older adults ages 50-80 would be open to stopping one or more of their prescribed medications, according to a 2023 poll by researchers at the University of Michigan, Ann Arbor.

“A lot of drugs that people take might have been appropriate at one point, but might have outlived their usefulness for that individual,” said Michael Steinman, MD, a professor of medicine and a geriatrician at the University of California, San Francisco, and coprincipal investigator of the U.S. Deprescribing Research Network, a doctor group focused on improving medication use for older adults.

“Having fewer medications can actually be beneficial,” he said. “You can take too many medications; you can take too few. The optimal thing is finding what is the right balance for you.”

Defining how many medications is too many depends on each person, which is why caregivers and older adults can ask their doctor for a review of medications that have multiplied over time.

By reevaluating their medications, older adults can actually lower their chances of potentially harmful side effects, and avoid the spiral of being prescribed even more medications, said Sarah Vordenberg, PharmD, MPH, a clinical associate professor at the University of Michigan’s College of Pharmacy, Ann Arbor.

“It’s not really the number of medications, it’s [about] are they inappropriate or unnecessary medications for a patient,” she said.

Patients and caregivers can ask for an honest conversation with their doctor. The University of Michigan poll found that more than 90% of older adults who took prescription medications expected their health care provider to review their medicines during a regular visit.

But doctors often need prompting from patients to start a review.

“The clinical inertia, or maintaining the status quo, unfortunately is a lot of times easier than having time-intensive conversations,” Dr. Vordenberg said.
 

 

 

Ask questions

Sara Merwin spent many years helping manage her parents’ medical appointments and health as they transitioned from living independently in Colorado to a retirement community and finally a nursing home. Ms. Merwin, coauthor of “The Informed Patient,” said her father was taking a long list of medications, and she often asked his primary care doctor for a medication review.

“I felt that my father at his age and his frailty didn’t need as many meds as he was on,” said Ms. Merwin, who lives in Long Island, N.Y. “So we went over his meds, and I asked, ‘Does he really need to be on this?’ ‘Does he really need to be on that?’ ”

She questioned one medication in particular, a statin to lower his cholesterol and risk of a heart attack.

“I thought possibly the statin was causing some myalgia, some muscle aches in his legs, which is why I advocated for coming off it,” she said. 

The primary care doctor discontinued the anticholesterol drug.

Local pharmacies can also serve as a starting point for older adults and caregivers, where a pharmacist can give them more information on whether a particular combination of the medications taken may be harmful. In states that allow for pharmacists to prescribe some medications, pharmacists may be able to consolidate some of the medications or advise that a patient stop taking one or more, Dr. Vordenberg said. 

“All pharmacists have the training to do a comprehensive medication review,” she said. “All pharmacists have the ability to follow up with the patient to find out how the deprescribing is going.”

Ms. Merwin’s parents received their prescriptions from a “small mom-and-pop pharmacy, where they were on a first-name basis with the pharmacist who really looked out for them. So they had that expertise available to them,” she said.

With information in hand on potentially unnecessary medications, the work of shedding medications should be done along with health care providers, some of whom prescribed the medications in the first place.

Many older adults live in geographically isolated areas without pharmacies, or receive prescriptions from mail-order pharmacies. In this case, Medicare plans offer free medication reviews with a doctor or pharmacist – known as a medication therapy management program – and provide recommendations for taking each drug.

Ms. Merwin’s father died in early 2020. She sometimes questions whether he should have stayed on the statin for longer, or if the doctor agreed too quickly without doing more research. But overall, she doesn’t regret raising the question with his health care providers, and she advises other caregivers and older adults to pay attention to medication lists.

“It’s dangerous to be passive when it comes to one’s health care now,” Ms. Merwin said. “That’s a difficult message for older adults to hear because they have grown up with the primacy of the doctor and the authority of the doctor, as opposed to it being a collaborative relationship.”

“I felt that my father at his age and his frailty didn’t need as many meds as he was on,” said Ms. Merwin, who lives in Long Island, N.Y. “So we went over his meds, and I asked, ‘Does he really need to be on this?’ ‘Does he really need to be on that?’ ”

She questioned one medication in particular, a statin to lower his cholesterol and risk of a heart attack.

“I thought possibly the statin was causing some myalgia, some muscle aches in his legs, which is why I advocated for coming off it,” she said. 

The primary care doctor discontinued the anticholesterol drug.

Local pharmacies can also serve as a starting point for older adults and caregivers, where a pharmacist can give them more information on whether a particular combination of the medications taken may be harmful. In states that allow for pharmacists to prescribe some medications, pharmacists may be able to consolidate some of the medications or advise that a patient stop taking one or more, Dr. Vordenberg said. 

“All pharmacists have the training to do a comprehensive medication review,” she said. “All pharmacists have the ability to follow up with the patient to find out how the deprescribing is going.”

Ms. Merwin’s parents received their prescriptions from a “small mom-and-pop pharmacy, where they were on a first-name basis with the pharmacist who really looked out for them. So they had that expertise available to them,” she said.

With information in hand on potentially unnecessary medications, the work of shedding medications should be done along with health care providers, some of whom prescribed the medications in the first place.

Many older adults live in geographically isolated areas without pharmacies, or receive prescriptions from mail-order pharmacies. In this case, Medicare plans offer free medication reviews with a doctor or pharmacist – known as a medication therapy management program – and provide recommendations for taking each drug.

Ms. Merwin’s father died in early 2020. She sometimes questions whether he should have stayed on the statin for longer, or if the doctor agreed too quickly without doing more research. But overall, she doesn’t regret raising the question with his health care providers, and she advises other caregivers and older adults to pay attention to medication lists.

“It’s dangerous to be passive when it comes to one’s health care now,” Ms. Merwin said. “That’s a difficult message for older adults to hear because they have grown up with the primacy of the doctor and the authority of the doctor, as opposed to it being a collaborative relationship.”

Joanne Lynn, MD, has lost track of the number of times in her 40 years as a geriatrician she’s seen a new patient come to her office carrying a bucket full of prescription medications – many of which they don’t need.

Dr. Lynn, who is on the faculty of George Washington University,Washington, recalled one woman who unwittingly was taking two blood pressure medications with different names.

“The risks included all the side effects overdosing carries,” Dr. Lynn said, ranging from blurred vision and crankiness to organ failure and even death.

For doctors with patients who don’t know they’re taking too much of a medication, “you wonder whether the drug is causing the health problems, and it’s a symptom of the wrong medication,” rather than a symptom of an undiagnosed illness, she said.

Many adults over age 65 with chronic conditions may be on too many medications and could benefit from a medication review with their primary care doctor. Patients often assume their health providers check for drug interactions or assess if a medication is no longer needed, and will catch extra prescriptions. That could be a risky assumption. Some doctors may prescribe yet another prescription to manage the side effects of an unnecessary drug, instead of doing a medication review and potentially “deprescribing” or discontinuing, a treatment that’s no longer needed.

About 57% of people age 65 years or older take five or more medications regularly – a concept known as polypharmacy, a study published in 2020 in the Journal of the American Geriatrics Society shows. While doctors prescribe drugs to help patients manage various ailments, as a list of medications grows, so do potential complications.

An older adult might forget to tell their doctor what they’re taking, or maybe they don’t even know what they’re taking or why, Dr. Lynn said.

“In some cases, a doctor just added a drug to treat something, not realizing they were already taking something else for it,” she said. “Of course, the situation of whether these patients can even afford all these drugs matters a lot, too.”

Some older adults may pick and choose which medications to take based on cost, not knowing which prescriptions are necessary, Dr. Lynn said.
 

Finding the ‘right balance’

Indeed, if given the option, up to 80% of older adults ages 50-80 would be open to stopping one or more of their prescribed medications, according to a 2023 poll by researchers at the University of Michigan, Ann Arbor.

“A lot of drugs that people take might have been appropriate at one point, but might have outlived their usefulness for that individual,” said Michael Steinman, MD, a professor of medicine and a geriatrician at the University of California, San Francisco, and coprincipal investigator of the U.S. Deprescribing Research Network, a doctor group focused on improving medication use for older adults.

“Having fewer medications can actually be beneficial,” he said. “You can take too many medications; you can take too few. The optimal thing is finding what is the right balance for you.”

Defining how many medications is too many depends on each person, which is why caregivers and older adults can ask their doctor for a review of medications that have multiplied over time.

By reevaluating their medications, older adults can actually lower their chances of potentially harmful side effects, and avoid the spiral of being prescribed even more medications, said Sarah Vordenberg, PharmD, MPH, a clinical associate professor at the University of Michigan’s College of Pharmacy, Ann Arbor.

“It’s not really the number of medications, it’s [about] are they inappropriate or unnecessary medications for a patient,” she said.

Patients and caregivers can ask for an honest conversation with their doctor. The University of Michigan poll found that more than 90% of older adults who took prescription medications expected their health care provider to review their medicines during a regular visit.

But doctors often need prompting from patients to start a review.

“The clinical inertia, or maintaining the status quo, unfortunately is a lot of times easier than having time-intensive conversations,” Dr. Vordenberg said.

Caring for the caregiver in dementia

THE CASE

Sam C* is a 68-year-old man who presented to his family physician in a rural health clinic due to concerns about weight loss. Since his visit 8 months prior, Mr. C unintentionally had lost 20 pounds. Upon questioning, Mr. C also reported feeling irritable and having difficulty with sleep and concentration.

A review of systems did not indicate the presence of infection or other medical conditions. In the 6 years since becoming a patient to the practice, he had reported no chronic health concerns, was taking no medications, and had only been to the clinic for his annual check-up appointments. He completed a Patient Health Questionnaire (PHQ-9) and scored 18, indicating moderately severe depression.

Mr. C had established care with his physician when he moved to the area from out of state so that he could be closer to his parents, who were in their mid-80s at the time. Mr. C’s physician also had been the family physician for his parents for the previous 20 years. Three years prior to Mr. C’s presentation for weight loss, his mother had received a diagnosis of acute leukemia; she died a year later.

Over the past year, Mr. C had needed to take a more active role in the care of his father, who was now in his early 90s. Mr. C’s father, who was previously in excellent health, had begun to develop significant health problems, including degenerative arthritis and progressive vascular dementia. He also had ataxia, leading to poor mobility, and a neurogenic bladder requiring self-catheterization, which required Mr. C’s assistance. Mr. C lived next door to his father and provided frequent assistance with activities of daily living. However, his father, who always had been the dominant figure in the family, was determined to maintain his independence and not relinquish control to others.

The strain of caregiving activities, along with managing his father’s inflexibility, was causing increasing distress for Mr. C. As he told his family physician, “I just don’t know what to do.”

How would you proceed with this patient?

It is estimated that more than 11 million Americans provided more than 18 billion hours in unpaid support for individuals with dementia in 2022, averaging 30 hours of care per caregiver per week.1 As individuals with dementia progressively decline, they require increased assistance with activities of daily living (ADLs, such as bathing and dressing) and instrumental activities of daily living (IADLs, such as paying bills and using transportation). Most of this assistance comes from informal caregiving provided by family members and friends.

Caregiver burden can be defined as “the strain or load borne by a person who cares for a chronically ill, disabled, or elderly family member.”2 Caregiver stress has been found to be higher for dementia caregiving than other types of caregiving.3 In particular, caring for someone with greater behavioral and psychological symptoms of dementia (BPSDs) has been associated with higher caregiver burden.4-7

Health outcomes associated with dementia caregiving

Beyond the subjective burden of care­giving, there are other potential negative ­consequences for dementia caregivers (see ­TABLE 18-14 and TABLE 215,16). In addition, caregiver distress is related to a number of care recipient outcomes, including earlier institutionalization, more hospitalizations, more BPSDs, poorer quality of life, and greater likelihood of experiencing elder abuse.17

Health conditions reported by dementia caregivers

Assessment, reassessment are key to meeting needs

Numerous factors can foster caregiver well-­being, including feelings of accomplishment and contribution, a strengthening of the relationship with the care recipient, and feeling supported by friends, family, and formal care systems.18,19 Family physicians can play an important role by assessing and supporting patients with dementia and their caregivers. Ideally, the individual with dementia and the caregiver will be assessed both together and separately.

Caregiver distress is related to care recipient outcomes, such as earlier institutionalization, more hospitalizations, and poorer quality of life.

A thorough assessment includes gathering information about the context and quality of the caregiving relationship; caregiver perception of the care recipient’s health and functional status; caregiver values and preferences; caregiver well-being (including mental health assessment); caregiver skills, abilities, and knowledge about caregiving; and positive and negative consequences of caregiving.20 Caregiver needs—including informational, care support, emotional, physical, and social needs—also should be assessed.

Continue to: Tools are available...

 

 

Tools are available to facilitate caregiver assessment. For example, the Zarit Burden Interview is a 22-item self-report measure that can be given to the caregiver21; shorter versions (4 and 12 items) are also available.22 Another resource available for caregiver assessment guidance is a toolkit developed by the Family Caregiver Alliance.20

Continually assess for changing needs

As the condition of the individual with dementia progresses, it will be important to reassess the caregiver, as stressors and needs will change over the course of the caregiving relationship. Support should be adapted ­accordingly.

In the early stage of dementia, caregivers may need information on disease progression and dementia care planning, ways to navigate the health care system, financial planning, and useful resources. Caregivers also may need emotional support to help them adapt to the role of caregiver, deal with denial, and manage their stress.23,24

With dementia progression, caregivers may need support related to increased decision-making responsibility, managing challenging behaviors, assisting with ADLs and IADLs, and identifying opportunities to meet personal social and well-being needs. They also may need support to accept the changes they are seeing in the individual with dementia and the shifts they are experiencing in their relationship with him or her.23,25

In late-stage dementia, caregiver needs tend to shift to determining the need for long-term care placement vs staying at home, end-of-life planning, loneliness, and anticipatory grief.23,26 Support with managing changing and accumulating stress typically remains a primary need throughout the progression of dementia.27

Continue to: Specific populations have distinct needs

 

 

Specific populations have distinct needs. Some caregivers, including members of the LGBTQ+ community and different racial and ethnic groups, as well as caregivers of people with younger-onset dementia, may have additional support needs.28

More than 11 million Americans provided more than 18 billion hours in unpaid support for individuals with dementia in 2022, averaging 30 hours of care per caregiver per week.

For example, African American and ­Latino caregivers tend to have caregiving relationships of longer duration, requiring more time-­intensive care, but use fewer formal support services than White caregivers.29 Caregivers from non-White racial and ethnic groups also are more likely to experience discrimination when interacting with health care services on behalf of care recipients.30

Having an awareness of potential specialized needs may help to prevent or address potential care disparities, and cultural humility may help to improve caregiver experiences with primary care physicians.

Resources to support caregivers

Family physicians are well situated to provide informational and emotional support for both patients with dementia and their informal care providers.31 Given the variability of caregiver concerns, multicomponent interventions addressing informational, self-care, social support, and financial needs often are needed.31 Supportive counseling and psychoeducation can help dementia caregivers with stress management, self-care, coping, and skills training—supporting the development of self-efficacy.32,33

Outside resources. Although significant caregiver support can be provided directly by the physician, caregivers should be connected with outside resources, including support groups, counselors, psychotherapists, financial and legal support, and formal care services.34

Continue to: Psychosocial and complementary interventions

 

 

Psychosocial and complementary interventions. Various psychosocial interventions (eg, psychoeducation, cognitive behavioral therapy, support groups) have been found to be beneficial in alleviating caregiver symptoms of depression, anxiety, and stress and improving well-being, perceived burden, and quality of life. However, systematic reviews have found variability in the degree of helpfulness of these interventions.35,36

Some caregivers and care recipients may benefit from complementary and integrative medicine referrals. Mind–body therapies such as mindfulness, yoga, and Tai Chi have shown some beneficial effects.37

Online resources. Caregivers also can be directed to online resources from organizations such as the Alzheimer’s Association (www.alz.org), the National Institutes of Health (www.alzheimers.gov), and the Family Caregiver Alliance (www.caregiver.org).

In rural settings, such as the one in which this case took place, online resources may decrease some barriers to supporting caregivers.38 Internet-based interventions also have been found to have some benefit for dementia caregivers.31,39

However, some rural locations continue to have limited reliable Internet services.40 In affected areas, a strong relationship with a primary care physician may be even more important to the well-being of caregivers, since other support services may be less accessible.41

Continue to: Impacts of the pandemic

 

 

Impacts of the pandemic. Although our case took place prior to the COVID-19 pandemic, it is important to acknowledge ways the pandemic has impacted informal dementia caregiving.

Caregiver stress, depression, and anxiety increased during the pandemic, and the need for greater home confinement and social ­distancing amplified the negative impact of social isolation, including loneliness, on ­caregivers.42,43 Caregivers often needed to increase their caregiving responsibilities and had more difficulty with care coordination due to limited access to in-person resources.43 The pandemic led to increased reliance on technology and telehealth in the support of dementia caregivers.43

THE CASE

The physician prescribed mirtazapine for Mr. C, titrating the dose as needed to address depressive symptoms and promote weight gain. The physician connected Mr. C’s father with home health services, including physical therapy for fall risk reduction. Mr. C also hired part-time support to provide additional assistance with ADLs and IADLs, allowing Mr. C to have time to attend to his own needs. Though provided with information about a local caregiver support group, Mr. C chose not to attend. The physician also assisted the family with advanced directives.

African American and Latino caregivers tend to have caregiving relationships of longer duration, requiring more time-intensive care, but they tend to use fewer formal support services than White caregivers.

A particular challenge that occurred during care for the family was addressing Mr. C’s father’s driving capacity, considering his strong need for independence. To address this concern, a family meeting was held with Mr. C, his father, and his siblings from out of town. Although Mr. C’s father was not willing to relinquish his driver’s license during that meeting, he agreed to complete a functional driving assessment.

The physician continued to meet with Mr. C and his father together, as well as with Mr. C individually, to provide supportive counseling as needed. As the father’s dementia progressed and it became more difficult to complete office appointments, the physician transitioned to home visits to provide care until the father’s death.

After the death of Mr. C’s father, the physician continued to serve as Mr. C’s primary care provider.

Keeping the “family”in family medicine

Through longitudinal assessment, needs identification, and provision of relevant information, emotional support, and resources, family physicians can provide care that can improve the quality of life and well-being and help alleviate burden experienced by dementia caregivers. Family physicians also are positioned to provide treatments that can address the negative physical and psychological health outcomes associated with informal dementia caregiving. By building relationships with multiple family members across generations, family physicians can understand the context of caregiving dynamics and work together with individuals with dementia and their caregivers throughout disease progression, providing consistent support to the family unit.

THE CASE

Sam C* is a 68-year-old man who presented to his family physician in a rural health clinic due to concerns about weight loss. Since his visit 8 months prior, Mr. C unintentionally had lost 20 pounds. Upon questioning, Mr. C also reported feeling irritable and having difficulty with sleep and concentration.

A review of systems did not indicate the presence of infection or other medical conditions. In the 6 years since becoming a patient to the practice, he had reported no chronic health concerns, was taking no medications, and had only been to the clinic for his annual check-up appointments. He completed a Patient Health Questionnaire (PHQ-9) and scored 18, indicating moderately severe depression.

Mr. C had established care with his physician when he moved to the area from out of state so that he could be closer to his parents, who were in their mid-80s at the time. Mr. C’s physician also had been the family physician for his parents for the previous 20 years. Three years prior to Mr. C’s presentation for weight loss, his mother had received a diagnosis of acute leukemia; she died a year later.

Over the past year, Mr. C had needed to take a more active role in the care of his father, who was now in his early 90s. Mr. C’s father, who was previously in excellent health, had begun to develop significant health problems, including degenerative arthritis and progressive vascular dementia. He also had ataxia, leading to poor mobility, and a neurogenic bladder requiring self-catheterization, which required Mr. C’s assistance. Mr. C lived next door to his father and provided frequent assistance with activities of daily living. However, his father, who always had been the dominant figure in the family, was determined to maintain his independence and not relinquish control to others.

The strain of caregiving activities, along with managing his father’s inflexibility, was causing increasing distress for Mr. C. As he told his family physician, “I just don’t know what to do.”

How would you proceed with this patient?

It is estimated that more than 11 million Americans provided more than 18 billion hours in unpaid support for individuals with dementia in 2022, averaging 30 hours of care per caregiver per week.1 As individuals with dementia progressively decline, they require increased assistance with activities of daily living (ADLs, such as bathing and dressing) and instrumental activities of daily living (IADLs, such as paying bills and using transportation). Most of this assistance comes from informal caregiving provided by family members and friends.

Caregiver burden can be defined as “the strain or load borne by a person who cares for a chronically ill, disabled, or elderly family member.”2 Caregiver stress has been found to be higher for dementia caregiving than other types of caregiving.3 In particular, caring for someone with greater behavioral and psychological symptoms of dementia (BPSDs) has been associated with higher caregiver burden.4-7

Health outcomes associated with dementia caregiving

Beyond the subjective burden of care­giving, there are other potential negative ­consequences for dementia caregivers (see ­TABLE 18-14 and TABLE 215,16). In addition, caregiver distress is related to a number of care recipient outcomes, including earlier institutionalization, more hospitalizations, more BPSDs, poorer quality of life, and greater likelihood of experiencing elder abuse.17

Health conditions reported by dementia caregivers

Assessment, reassessment are key to meeting needs

Numerous factors can foster caregiver well-­being, including feelings of accomplishment and contribution, a strengthening of the relationship with the care recipient, and feeling supported by friends, family, and formal care systems.18,19 Family physicians can play an important role by assessing and supporting patients with dementia and their caregivers. Ideally, the individual with dementia and the caregiver will be assessed both together and separately.

Caregiver distress is related to care recipient outcomes, such as earlier institutionalization, more hospitalizations, and poorer quality of life.

A thorough assessment includes gathering information about the context and quality of the caregiving relationship; caregiver perception of the care recipient’s health and functional status; caregiver values and preferences; caregiver well-being (including mental health assessment); caregiver skills, abilities, and knowledge about caregiving; and positive and negative consequences of caregiving.20 Caregiver needs—including informational, care support, emotional, physical, and social needs—also should be assessed.

Continue to: Tools are available...

 

 

Tools are available to facilitate caregiver assessment. For example, the Zarit Burden Interview is a 22-item self-report measure that can be given to the caregiver21; shorter versions (4 and 12 items) are also available.22 Another resource available for caregiver assessment guidance is a toolkit developed by the Family Caregiver Alliance.20

Continually assess for changing needs

As the condition of the individual with dementia progresses, it will be important to reassess the caregiver, as stressors and needs will change over the course of the caregiving relationship. Support should be adapted ­accordingly.

In the early stage of dementia, caregivers may need information on disease progression and dementia care planning, ways to navigate the health care system, financial planning, and useful resources. Caregivers also may need emotional support to help them adapt to the role of caregiver, deal with denial, and manage their stress.23,24

With dementia progression, caregivers may need support related to increased decision-making responsibility, managing challenging behaviors, assisting with ADLs and IADLs, and identifying opportunities to meet personal social and well-being needs. They also may need support to accept the changes they are seeing in the individual with dementia and the shifts they are experiencing in their relationship with him or her.23,25

In late-stage dementia, caregiver needs tend to shift to determining the need for long-term care placement vs staying at home, end-of-life planning, loneliness, and anticipatory grief.23,26 Support with managing changing and accumulating stress typically remains a primary need throughout the progression of dementia.27

Continue to: Specific populations have distinct needs

 

 

Specific populations have distinct needs. Some caregivers, including members of the LGBTQ+ community and different racial and ethnic groups, as well as caregivers of people with younger-onset dementia, may have additional support needs.28

More than 11 million Americans provided more than 18 billion hours in unpaid support for individuals with dementia in 2022, averaging 30 hours of care per caregiver per week.

For example, African American and ­Latino caregivers tend to have caregiving relationships of longer duration, requiring more time-­intensive care, but use fewer formal support services than White caregivers.29 Caregivers from non-White racial and ethnic groups also are more likely to experience discrimination when interacting with health care services on behalf of care recipients.30

Having an awareness of potential specialized needs may help to prevent or address potential care disparities, and cultural humility may help to improve caregiver experiences with primary care physicians.

Resources to support caregivers

Family physicians are well situated to provide informational and emotional support for both patients with dementia and their informal care providers.31 Given the variability of caregiver concerns, multicomponent interventions addressing informational, self-care, social support, and financial needs often are needed.31 Supportive counseling and psychoeducation can help dementia caregivers with stress management, self-care, coping, and skills training—supporting the development of self-efficacy.32,33

Outside resources. Although significant caregiver support can be provided directly by the physician, caregivers should be connected with outside resources, including support groups, counselors, psychotherapists, financial and legal support, and formal care services.34

Continue to: Psychosocial and complementary interventions

 

 

Psychosocial and complementary interventions. Various psychosocial interventions (eg, psychoeducation, cognitive behavioral therapy, support groups) have been found to be beneficial in alleviating caregiver symptoms of depression, anxiety, and stress and improving well-being, perceived burden, and quality of life. However, systematic reviews have found variability in the degree of helpfulness of these interventions.35,36

Some caregivers and care recipients may benefit from complementary and integrative medicine referrals. Mind–body therapies such as mindfulness, yoga, and Tai Chi have shown some beneficial effects.37

Online resources. Caregivers also can be directed to online resources from organizations such as the Alzheimer’s Association (www.alz.org), the National Institutes of Health (www.alzheimers.gov), and the Family Caregiver Alliance (www.caregiver.org).

In rural settings, such as the one in which this case took place, online resources may decrease some barriers to supporting caregivers.38 Internet-based interventions also have been found to have some benefit for dementia caregivers.31,39

However, some rural locations continue to have limited reliable Internet services.40 In affected areas, a strong relationship with a primary care physician may be even more important to the well-being of caregivers, since other support services may be less accessible.41

Continue to: Impacts of the pandemic

 

 

Impacts of the pandemic. Although our case took place prior to the COVID-19 pandemic, it is important to acknowledge ways the pandemic has impacted informal dementia caregiving.

Caregiver stress, depression, and anxiety increased during the pandemic, and the need for greater home confinement and social ­distancing amplified the negative impact of social isolation, including loneliness, on ­caregivers.42,43 Caregivers often needed to increase their caregiving responsibilities and had more difficulty with care coordination due to limited access to in-person resources.43 The pandemic led to increased reliance on technology and telehealth in the support of dementia caregivers.43

THE CASE

The physician prescribed mirtazapine for Mr. C, titrating the dose as needed to address depressive symptoms and promote weight gain. The physician connected Mr. C’s father with home health services, including physical therapy for fall risk reduction. Mr. C also hired part-time support to provide additional assistance with ADLs and IADLs, allowing Mr. C to have time to attend to his own needs. Though provided with information about a local caregiver support group, Mr. C chose not to attend. The physician also assisted the family with advanced directives.

African American and Latino caregivers tend to have caregiving relationships of longer duration, requiring more time-intensive care, but they tend to use fewer formal support services than White caregivers.

A particular challenge that occurred during care for the family was addressing Mr. C’s father’s driving capacity, considering his strong need for independence. To address this concern, a family meeting was held with Mr. C, his father, and his siblings from out of town. Although Mr. C’s father was not willing to relinquish his driver’s license during that meeting, he agreed to complete a functional driving assessment.

The physician continued to meet with Mr. C and his father together, as well as with Mr. C individually, to provide supportive counseling as needed. As the father’s dementia progressed and it became more difficult to complete office appointments, the physician transitioned to home visits to provide care until the father’s death.

After the death of Mr. C’s father, the physician continued to serve as Mr. C’s primary care provider.

Keeping the “family”in family medicine

Through longitudinal assessment, needs identification, and provision of relevant information, emotional support, and resources, family physicians can provide care that can improve the quality of life and well-being and help alleviate burden experienced by dementia caregivers. Family physicians also are positioned to provide treatments that can address the negative physical and psychological health outcomes associated with informal dementia caregiving. By building relationships with multiple family members across generations, family physicians can understand the context of caregiving dynamics and work together with individuals with dementia and their caregivers throughout disease progression, providing consistent support to the family unit.

Is the WHO’s ‘active aging’ the only healthy alternative?

 – In the “active aging” vision promoted by the World Health Organization (WHO), older adults stay physically active, independent, and involved. This concept, though well-intentioned, is not very realistic and could easily be discouraging to individuals suffering from the psychological or physical limitations of old age. It also does not account for diversity among individuals and across cultures. These conclusions were presented by the Geriatric Psychiatry Chapter of the Argentine Psychiatric Association at its XXXVI Argentine Congress of Psychiatry.

“The WHO’s proposal of active aging is a prescriptive, standardized ideology that seems to suggest that being active is the only healthy way to age. However, that’s only part of the picture, and a biased part at that. It doesn’t account for the broad spectrum of aging processes that come in many shades,” said Mariana Pedace, psychologist with the Adult Intensive Care department at the Italian Hospital in Buenos Aires and head of the Older Adults section of the civic association Project: Unite.

“The question is whether the idea of active aging is just one more way to create mandates or rules for older adults, which make up such a heterogeneous and diverse generation,” said Ana Laura Vega, MD, psychiatrist with the Mental Health Department at the Italian Hospital of Buenos Aires.

Might it be better to speak of aging “as expected” or “aging well”? Speakers at the conference did not reach a consensus on which word would be the best to replace the adjective “active.”

“I don’t really see why there has to be an additional term when, at other stages of life, we only talk about ‘infancy,’ ‘adolescence,’ or ‘middle age,’ ” said Dr. Vega.
 

A thorny issue

Since the late 1990s, the WHO has defined active aging as “the process of optimizing opportunities for health, participation, and security to enhance quality of life as people age.” This concept allows older adults to “realize their potential for physical, social, and mental well-being throughout the life course and to participate in society according to their needs, desires, and capacities, while providing them with adequate protection, security, and care when they require assistance.”

The organization clarifies that the word “active” refers to continuing participation in social, economic, cultural, spiritual, and civic affairs, not just the ability to be physically active or to participate in the labor force. “However, in practice, active aging programs invariably promote physical activity and exercise as having health and social benefits,” said sociologist Elizabeth Pike, PhD, head of the Research Unit in Sport, Physical Activity, and Aging at the University of Hertfordshire in the United Kingdom.

“The concept of active aging, as presented, is a thorny issue and can potentially be problematic,” said Dr. Pedace. Along with laying out a single prescriptive way to age healthily, which by default makes passive aging “abnormal,” it also ignores demographic, ethnographic, and cultural differences.

“Each culture has different values. The suggestion of aging well in terms of activity, autonomy, and a happy-go-lucky mindset clearly reflects Western capitalistic values. In Eastern cultures, elderly people occupy a position reflecting their experience and wisdom, while also maintaining a contemplative mindset, which is something that is held in high regard. They are at the heart of the family, and their role is to guide and counsel the younger generations,” said Dr. Pedace.

The specialist added that there are programs inspired by active aging that prioritize outward, dynamic, and observable activities to the detriment of activities that take place behind the scenes such as reflection, analysis, and contemplation. “Following this mindset, an older individual who spends their time in contemplation would be somewhat wasting their sunset years. This raises a problem, because as the years go by and death approaches, spiritual life begins to gain far more significance. And that’s not an activity that is valued or recommended in the terms of this program,” she said.

Dr. Pedace went on to say that another concern with the active-aging program is that it seems to minimize certain characteristics that are unique to old age. Resulting physical, cognitive, and emotional changes can lead to reduced activity but are merely idiosyncrasies of this stage in life and are not pathologic.

Cecilia Guerstein, psychiatrist with the Older Adults Division of Project: United in Buenos Aires, cited Julieta Oddone, PhD, a sociologist on aging who believes that the theory of activity informs the underlying supposition of most programs for older adults: that social activity in itself is beneficial and results in greater fulfillment in life. And that all older people need and desire to stay active and engaged. “The idea is that the more active they are, the happier they will be,” said Dr. Guerstein.

“But ‘doing things’ isn’t necessarily appreciated by every elderly person, nor does it automatically lead to their well-being. The fact that some find a sense of well-being from it doesn’t mean we have to always do the same activities across different contexts. There are ethnographic studies that show that there isn’t necessarily a relationship between activity and well-being, or true social integration,” said Dr. Pedace.
 

 

 

Not a burden

Practically speaking, few would question whether physical activity has health benefits and believe that it’s never too late to start moving. Among his more than 45 tips on how to live to a ripe old age and “ripen” slowly and nicely, George D. Lundberg, MD, who is 90 years old, gives six recommendations for exercise: walking at least 2 miles every day, trying to swim every day, learning and practicing the techniques of yoga, deliberately lifting heavy objects (resistance training), and working on balance.

“A key for health care professionals encouraging exercise among older adults is knowing what to listen for and how to identify situations that motivate the person to exercise. For example, it could be walking their granddaughter down to the ice cream parlor,” Carolina Díaz, MD, said in an interview. Dr. Díaz is a geriatrics physician and the medical director of the Hirsch nursing and rehab center for older people in San Miguel, Argentina, which is home to 180 residents with an average age of 82 years.

“Exercise shouldn’t be a burden. If someone has never gone on walks before, I wouldn’t make them walk just because they ought to. Maybe they discover well-being in meeting up with their grandchildren or reading with someone. We believe that well-being is related to mobility, but for someone to move, they need the motivation. And until they have that, there won’t be any change,” said Dr. Díaz.

She added that a physician-patient relationship must be forged and an intervention plan drafted that revolves around the person and focuses on his or her current problems such as loneliness, difficulty walking, or pain. “Based on those problems, we can draw up a plan in which physical activity may play a part; other times, it may not.”

Osvaldo Bodni, psychiatrist and psychoanalyst, former director of the Department for Older Adults within the Argentine Psychoanalytic Association and author of the book, Delegating Power in Human Aging: The Theory of Legacy and Passing the Baton) said in an interview: “Aging isn’t a disease, though it does increase vulnerability. The proposal of physical activity is not the only ‘antidote.’ In my opinion, serenity during aging provides even better protection against life’s storms.”

The physician went on to say, “Active aging programs promote physical activity because it’s easier to go on a walk with someone than it is to have a literature debate with them. However, the goal is to create a feeling of being part of a group. This isn’t bad, but it’s a replacement for family. Being part of a group has come to fill the place that was once filled by one’s children, grandchildren, and students.

“When the flood of change in modern society rushes in so quickly, there is a ‘programmed phase-out’ of knowledge, and the demand for experience drops off. It becomes less valuable, such that older adults often get more comfort from finding someone who is willing to show an interest in their stories. The best therapist is the one who listens; not necessarily the one who invites them on a walk or a bike ride,” concluded Dr. Bodni.

Dr. Vega, Dr. Guerstein, Dr. Díaz, Dr. Bodni, and Dr. Pedace have disclosed no relevant financial relationships.

Resulting physical, cognitive, and emotional changes can lead to reduced activity but are merely idiosyncrasies of this stage in life and are not pathologic.

Cecilia Guerstein, psychiatrist with the Older Adults Division of Project: United in Buenos Aires, cited Julieta Oddone, PhD, a sociologist on aging who believes that the theory of activity informs the underlying supposition of most programs for older adults: that social activity in itself is beneficial and results in greater fulfillment in life. And that all older people need and desire to stay active and engaged. “The idea is that the more active they are, the happier they will be,” said Dr. Guerstein.

“But ‘doing things’ isn’t necessarily appreciated by every elderly person, nor does it automatically lead to their well-being. The fact that some find a sense of well-being from it doesn’t mean we have to always do the same activities across different contexts. There are ethnographic studies that show that there isn’t necessarily a relationship between activity and well-being, or true social integration,” said Dr. Pedace.
 

 

 

Not a burden

Practically speaking, few would question whether physical activity has health benefits and believe that it’s never too late to start moving. Among his more than 45 tips on how to live to a ripe old age and “ripen” slowly and nicely, George D. Lundberg, MD, who is 90 years old, gives six recommendations for exercise: walking at least 2 miles every day, trying to swim every day, learning and practicing the techniques of yoga, deliberately lifting heavy objects (resistance training), and working on balance.

“A key for health care professionals encouraging exercise among older adults is knowing what to listen for and how to identify situations that motivate the person to exercise. For example, it could be walking their granddaughter down to the ice cream parlor,” Carolina Díaz, MD, said in an interview. Dr. Díaz is a geriatrics physician and the medical director of the Hirsch nursing and rehab center for older people in San Miguel, Argentina, which is home to 180 residents with an average age of 82 years.

“Exercise shouldn’t be a burden. If someone has never gone on walks before, I wouldn’t make them walk just because they ought to. Maybe they discover well-being in meeting up with their grandchildren or reading with someone. We believe that well-being is related to mobility, but for someone to move, they need the motivation. And until they have that, there won’t be any change,” said Dr. Díaz.

She added that a physician-patient relationship must be forged and an intervention plan drafted that revolves around the person and focuses on his or her current problems such as loneliness, difficulty walking, or pain. “Based on those problems, we can draw up a plan in which physical activity may play a part; other times, it may not.”

Osvaldo Bodni, psychiatrist and psychoanalyst, former director of the Department for Older Adults within the Argentine Psychoanalytic Association and author of the book, Delegating Power in Human Aging: The Theory of Legacy and Passing the Baton) said in an interview: “Aging isn’t a disease, though it does increase vulnerability. The proposal of physical activity is not the only ‘antidote.’ In my opinion, serenity during aging provides even better protection against life’s storms.”

The physician went on to say, “Active aging programs promote physical activity because it’s easier to go on a walk with someone than it is to have a literature debate with them. However, the goal is to create a feeling of being part of a group. This isn’t bad, but it’s a replacement for family. Being part of a group has come to fill the place that was once filled by one’s children, grandchildren, and students.

“When the flood of change in modern society rushes in so quickly, there is a ‘programmed phase-out’ of knowledge, and the demand for experience drops off. It becomes less valuable, such that older adults often get more comfort from finding someone who is willing to show an interest in their stories. The best therapist is the one who listens; not necessarily the one who invites them on a walk or a bike ride,” concluded Dr. Bodni.

 – In the “active aging” vision promoted by the World Health Organization (WHO), older adults stay physically active, independent, and involved. This concept, though well-intentioned, is not very realistic and could easily be discouraging to individuals suffering from the psychological or physical limitations of old age. It also does not account for diversity among individuals and across cultures. These conclusions were presented by the Geriatric Psychiatry Chapter of the Argentine Psychiatric Association at its XXXVI Argentine Congress of Psychiatry.

“The WHO’s proposal of active aging is a prescriptive, standardized ideology that seems to suggest that being active is the only healthy way to age. However, that’s only part of the picture, and a biased part at that. It doesn’t account for the broad spectrum of aging processes that come in many shades,” said Mariana Pedace, psychologist with the Adult Intensive Care department at the Italian Hospital in Buenos Aires and head of the Older Adults section of the civic association Project: Unite.

“The question is whether the idea of active aging is just one more way to create mandates or rules for older adults, which make up such a heterogeneous and diverse generation,” said Ana Laura Vega, MD, psychiatrist with the Mental Health Department at the Italian Hospital of Buenos Aires.

Might it be better to speak of aging “as expected” or “aging well”? Speakers at the conference did not reach a consensus on which word would be the best to replace the adjective “active.”

“I don’t really see why there has to be an additional term when, at other stages of life, we only talk about ‘infancy,’ ‘adolescence,’ or ‘middle age,’ ” said Dr. Vega.
 

A thorny issue

Since the late 1990s, the WHO has defined active aging as “the process of optimizing opportunities for health, participation, and security to enhance quality of life as people age.” This concept allows older adults to “realize their potential for physical, social, and mental well-being throughout the life course and to participate in society according to their needs, desires, and capacities, while providing them with adequate protection, security, and care when they require assistance.”

The organization clarifies that the word “active” refers to continuing participation in social, economic, cultural, spiritual, and civic affairs, not just the ability to be physically active or to participate in the labor force. “However, in practice, active aging programs invariably promote physical activity and exercise as having health and social benefits,” said sociologist Elizabeth Pike, PhD, head of the Research Unit in Sport, Physical Activity, and Aging at the University of Hertfordshire in the United Kingdom.

“The concept of active aging, as presented, is a thorny issue and can potentially be problematic,” said Dr. Pedace. Along with laying out a single prescriptive way to age healthily, which by default makes passive aging “abnormal,” it also ignores demographic, ethnographic, and cultural differences.

“Each culture has different values. The suggestion of aging well in terms of activity, autonomy, and a happy-go-lucky mindset clearly reflects Western capitalistic values. In Eastern cultures, elderly people occupy a position reflecting their experience and wisdom, while also maintaining a contemplative mindset, which is something that is held in high regard. They are at the heart of the family, and their role is to guide and counsel the younger generations,” said Dr. Pedace.

The specialist added that there are programs inspired by active aging that prioritize outward, dynamic, and observable activities to the detriment of activities that take place behind the scenes such as reflection, analysis, and contemplation. “Following this mindset, an older individual who spends their time in contemplation would be somewhat wasting their sunset years. This raises a problem, because as the years go by and death approaches, spiritual life begins to gain far more significance. And that’s not an activity that is valued or recommended in the terms of this program,” she said.

Dr. Pedace went on to say that another concern with the active-aging program is that it seems to minimize certain characteristics that are unique to old age. Resulting physical, cognitive, and emotional changes can lead to reduced activity but are merely idiosyncrasies of this stage in life and are not pathologic.

Muscle fat: A new risk factor for cognitive decline?

Muscle adiposity may be a novel risk factor for cognitive decline in older adults, new research suggests.

Investigators assessed muscle fat in more than 1,600 adults in their 70s and evaluated their cognitive function over a 10-year period. They found that increases in muscle adiposity from year 1 to year 6 were associated with greater cognitive decline over time, independent of total weight, other fat deposits, muscle characteristics, and traditional dementia risk factors.

The findings were similar between Black and White people and between men and women.

“Increasing adiposity – or fat deposition – in skeletal muscles predicted faster cognitive decline, irrespective of demographics or other disease, and this effect was distinct from that of other types of fat or other muscle characteristics, such as strength or mass,” study investigator Caterina Rosano MD, MPH, professor of epidemiology at the University of Pittsburgh, said in an interview.

The study was published in the Journal of the American Geriatrics Society.
 

Biologically plausible

“There has been a growing recognition that overall adiposity and muscle measures, such as strength and mass, are individual indicators of future dementia risk and both strengthen the algorithms to predict cognitive decline,” said Dr. Rosano, associate director for clinical translation at the University of Pittsburgh’s Aging Institute. “However, adiposity in the muscle has not been examined.”

Some evidence supports a “biologically plausible link” between muscle adiposity and dementia risk. For example, muscle adiposity increases the risk for type 2 diabetes and hypertension, both of which are dementia risk factors.

Skeletal muscle adiposity increases with older age, even in older adults who lose weight, and is “highly prevalent” among older adults of African ancestry.

The researchers examined a large, biracial sample of older adults participating in the Health, Aging and Body Composition study, which enrolled men and women aged between 70 and 79 years. Participants were followed for an average of 9.0 ± 1.8 years.

During years 1 and 6, participants’ body composition was analyzed, including intermuscular adipose tissue (IMAT), visceral and subcutaneous adiposity, total fat mass, and muscle area.

In years 1, 3, 5, 8, and 10, participants’ cognition was measured using the modified Mini-Mental State (3MS) exam.

The main independent variable was 5-year change in thigh IMAT (year 6 minus year 1), and the main dependent variable was 3MS decline (from year 5 to year 10).

The researchers adjusted all the models for traditional dementia risk factors at baseline including 3MS, education, apo E4 allele, diabetes, hypertension, and physical activity and also calculated interactions between IMAT change by race or sex.

These models also accounted for change in muscle strength, muscle area, body weight, abdominal subcutaneous and visceral adiposity, and total body fat mass as well as cytokines related to adiposity.
 

‘Rich and engaging crosstalk’

The final sample included 1634 participants (mean age, 73.38 years at baseline; 48% female; 35% Black; mean baseline 3MS score, 91.6).

Thigh IMAT increased by 39.0% in all participants from year 1 to year 6, which corresponded to an increase of 4.85 cm2 or 0.97 cm2/year. During the same time period, muscle strength decreased by 14.0% (P < .05), although thigh muscle area remained stable, decreasing less than 0.5%.

There were decreases in both abdominal subcutaneous and visceral adiposity of 3.92% and 6.43%, respectively (P < .05). There was a decrease of 3.3% in 3MS from year 5 to year 10.

Several variables were associated with 3MS decline, independent of any change in thigh IMAT: older age, less education, and having at least one copy of the APOe4 allele. These variables were included in the model of IMAT change predicting 3MS change.

A statistically significant association of IMAT increase with 3MS decline was found. The IMAT increase of 4.85 cm2 corresponded to a 3MS decline of an additional 3.6 points (P < .0001) from year 5 to year 10, “indicating a clinically important change.”

The association between increasing thigh IMAT with declining 3MS “remained statistically significant” after adjusting for race, age, education, and apo E4 (P < .0001) and was independent of changes in thigh muscle area, muscle strength, and other adiposity measures.

In participants with increased IMAT in years 1-6, the mean 3MS score fell to approximately 87 points at year 10, compared with those without increased IMAT, with a 3MS score that dropped to approximately 89 points.

Interactions by race and sex were not statistically significant (P > .08).

“Our results suggest that adiposity in muscles can predict cognitive decline, in addition to (not instead of) other traditional dementia risk factors,” said Dr. Rosano.

There is “a rich and engaging crosstalk between muscle, adipose tissue, and the brain all throughout our lives, happening through factors released in the bloodstream that can reach the brain, however, the specific identity of the factors responsible for the crosstalk of muscle adiposity and brain in older adults has not yet been discovered,” she noted.

Although muscle adiposity is “not yet routinely measured in clinical settings, it is being measured opportunistically on clinical CT scans obtained as part of routine patient care,” she added. “These CT measurements have already been validated in many studies of older adults; thus, clinicians could have access to this novel information without additional cost, time, or radiation exposure.”
 

Causality not proven

In a comment, Bruce Albala, PhD, professor, department of environmental and occupational health, University of California, Irvine, noted that the 3MS assessment is scored on a 100-point scale, with a score less than 78 “generally regarded as indicating cognitive impairment or approaching a dementia condition.” In the current study, the mean 3MS score of participants with increased IMAT was still “well above the dementia cut-off.”

Moreover, “even if there is a relationship or correlation between IMAT and cognition, this does not prove or even suggest causality, especially from a biological mechanistic approach,” said Dr. Albaba, an adjunct professor of neurology, who was not involved in the study. “Clearly, more research is needed even to understand the relationship between these two factors.”

The study was supported by the National Institute on Aging. Dr. Rosano and coauthors and Dr. Albala declared no relevant financial relationships.

Blood biomarker may help predict who will develop Alzheimer’s

Wed, 06/14/2023 - 09:41

A blood biomarker that measures astrocyte reactivity may help determine who, among cognitively unimpaired older adults with amyloid-beta, will go on to develop Alzheimer’s disease (AD), new research suggests.

Investigators tested the blood of 1,000 cognitively healthy individuals with and without amyloid-beta pathology and found that only those with a combination of amyloid-beta burden and abnormal astrocyte activation subsequently progressed to AD.

“Our study argues that testing for the presence of brain amyloid along with blood biomarkers of astrocyte reactivity is the optimal screening to identify patients who are most at risk for progressing to Alzheimer’s disease,” senior investigator Tharick A. Pascoal, MD, PhD, associate professor of psychiatry and neurology, University of Pittsburgh, said in a release.

At this point, the biomarker is a research tool, but its application in clinical practice “is not very far away,” Dr. Pascoal told this news organization.

The study was published online  in Nature Medicine.  
 

Multicenter study

In AD, accumulation of amyloid-beta in the brain precedes tau pathology, but not everyone with amyloid-beta develops tau, and, consequently, clinical symptoms. Approximately 30% of older adults have brain amyloid but many never progress to AD, said Dr. Pascoal.

This suggests other biological processes may trigger the deleterious effects of amyloid-beta in the early stages of AD.

Finding predictive markers of early amyloid-beta–related tau pathology would help identify cognitively normal individuals who are more likely to develop AD.

Post-mortem studies show astrocyte reactivity – changes in glial cells in the brain and spinal cord because of an insult in the brain – is an early AD abnormality. Other research suggests a close link between amyloid-beta, astrocyte reactivity, and tau.

In addition, evidence suggests plasma measures of glial fibrillary acidic protein (GFAP) could be a strong proxy of astrocyte reactivity in the brain. Dr. Pascoal explained that when astrocytes are changed or become bigger, more GFAP is released.

The study included 1,016 cognitively normal individuals from three centers; some had amyloid pathology, some did not. Participants’ mean age was 69.6 years, and all were deemed negative or positive for astrocyte reactivity based on plasma GFAP levels.

Results showed amyloid-beta is associated with increased plasma phosphorylated tau only in individuals positive for astrocyte reactivity. In addition, analyses using PET scans showed an AD-like pattern of tau tangle accumulation as a function of amyloid-beta exclusively in those same individuals.
 

Early upstream event

The findings suggest abnormalities in astrocyte reactivity is an early upstream event that likely occurs prior to tau pathology, which is closely related to the development of neurodegeneration and cognitive decline.

It’s likely many types of insults or processes can lead to astrocyte reactivity, possibly including COVID, but more research in this area is needed, said Dr. Pascoal.

“Our study only looked at the consequence of having both amyloid and astrocyte reactivity; it did not elucidate what is causing either of them,” he said.

Although “we were able to have very good results” in the current study, additional studies are needed to better establish the cut-off for GFAP levels that signal progression, said Dr. Pascoal.

The effect of astrocyte reactivity on the association between amyloid-beta and tau phosphorylation was greater in men than women. Dr. Pascoal noted anti-amyloid therapies, which might be modifying the amyloid-beta-astrocyte-tau pathway, tend to have a much larger effect in men than women.

Further studies that measure amyloid-beta, tau, and GFAP biomarkers at multiple timepoints, and with long follow-up, are needed, the investigators note.

The results may have implications for clinical trials, which have increasingly focused on individuals in the earliest preclinical phases of AD. Future studies should include cognitively normal patients who are positive for both amyloid pathology and astrocyte reactivity but have no overt p-tau abnormality, said Dr. Pascoal.

This may provide a time window for interventions very early in the disease process in those at increased risk for AD-related progression.

The study did not determine whether participants with both amyloid and astrocyte reactivity will inevitably develop AD, and to do so would require a longer follow up. “Our outcome was correlation to tau in the brain, which is something we know will lead to AD.”

Although the cohort represents significant socioeconomic diversity, a main limitation of the study was that subjects were mainly White, which limits the generalizability of the findings to a more diverse population.

A blood biomarker that measures astrocyte reactivity may help determine who, among cognitively unimpaired older adults with amyloid-beta, will go on to develop Alzheimer’s disease (AD), new research suggests.

Investigators tested the blood of 1,000 cognitively healthy individuals with and without amyloid-beta pathology and found that only those with a combination of amyloid-beta burden and abnormal astrocyte activation subsequently progressed to AD.

“Our study argues that testing for the presence of brain amyloid along with blood biomarkers of astrocyte reactivity is the optimal screening to identify patients who are most at risk for progressing to Alzheimer’s disease,” senior investigator Tharick A. Pascoal, MD, PhD, associate professor of psychiatry and neurology, University of Pittsburgh, said in a release.

At this point, the biomarker is a research tool, but its application in clinical practice “is not very far away,” Dr. Pascoal told this news organization.

The study was published online  in Nature Medicine.
