Receipt of a newer recombinant version of a shingles vaccine is associated with a significant delay in dementia diagnosis in older adults, a new study suggests.

The study builds on previous observations of a reduction in dementia risk with the older live shingles vaccine and reports a delay in dementia diagnosis of 164 days with the newer recombinant version, compared with the live vaccine. 

“Given the prevalence of dementia, a delay of 164 days in diagnosis would not be a trivial effect at the public health level. It’s a big enough effect that if there is a causality it feels meaningful,” said senior author Paul Harrison, DM, FRCPsych, professor of psychiatry at the University of Oxford, Oxford, England. 

But Dr. Harrison stressed that the study had not proven that the shingles vaccine reduced dementia risk. 

“The design of the study allows us to do away with many of the confounding effects we usually see in observational studies, but this is still an observational study, and as such it cannot prove a definite causal effect,” he said. 

The study was published online on July 25 in Nature Medicine.
 

‘Natural Experiment’

Given the risk for deleterious consequences of shingles, vaccination is now recommended for older adults in many countries. The previously used live shingles vaccine (Zostavax) is being replaced in most countries with the new recombinant shingles vaccine (Shingrix), which is more effective at preventing shingles infection. 

The current study made use of a “natural experiment” in the United States, which switched over from use of the live vaccine to the recombinant vaccine in October 2017. 

Researchers used electronic heath records to compare the incidence of a dementia diagnosis in individuals who received the live shingles vaccine prior to October 2017 with those who received the recombinant version after the United States made the switch. 

They also used propensity score matching to further control for confounding factors, comparing 103,837 individuals who received a first dose of the live shingles vaccine between October 2014 and September 2017 with the same number of matched people who received the recombinant vaccine between November 2017 and October 2020. 

Results showed that within the 6 years after vaccination, the recombinant vaccine was associated with a delay in the diagnosis of dementia, compared with the live vaccine. Specifically, receiving the recombinant vaccine was associated with a 17% increase in diagnosis-free time, translating to 164 additional days lived without a diagnosis of dementia in those subsequently affected. 

As an additional control, the researchers also found significantly lower risks for dementia in individuals receiving the new recombinant shingles vaccine vs two other vaccines commonly used in older people: influenza and tetanus/diphtheria/pertussis vaccines, with increases in diagnosis-free time of 14%-27%. 

Reduced Risk or Delayed Diagnosis?

Speaking at a Science Media Centre press conference on the study, lead author Maxime Taquet, PhD, FRCPsych, clinical lecturer in psychiatry at the University of Oxford, noted that the total number of dementia cases were similar in the two shingles vaccine groups by the end of the 6-year follow-up period but there was a difference in the time at which they received a diagnosis of dementia.

“The study suggests that rather than actually reducing dementia risk, the recombinant vaccine delays the onset of dementia compared to the live vaccine in patients who go on to develop the condition,” he explained. 

But when comparing the recombinant vaccine with the influenza and tetanus/diphtheria/pertussis vaccines there was a clear reduction in dementia risk itself, Dr. Taquet reported. 

“It might well be that the live vaccine has a potential effect on the risk of dementia itself and therefore the recombinant vaccine only shows a delay in dementia compared to the live vaccine, but both of them might decrease the overall risk of dementia,” he suggested. 

But the researchers cautioned that this study could not prove causality. 

“While the two groups were very carefully matched in terms of factors that might influence the development of dementia, we still have to be cautious before assuming that the vaccine is indeed causally reducing the risk of onset of dementia,” Dr. Harrison warned. 

The researchers say the results would need to be confirmed in a randomized trial, which may have to be conducted in a slightly younger age group, as currently shingles vaccine is recommended for all older individuals in the United Kingdom. 

Vaccine recommendations vary from country to country, Dr. Harrison added. In the United States, the Centers for Disease Control and Prevention recommends the recombinant shingles vaccine for all adults aged 50 years or older. 

In the meantime, it would be interesting to see whether further observational studies in other countries find similar results as this US study, Dr. Harrison said.  
 

Mechanism Uncertain

Speculating on a possible mechanism behind the findings, Dr. Harrison suggested two plausible explanations.

“First, it is thought that the herpes virus could be one of many factors that could promote dementia, so a vaccine that stops reactivation of this virus might therefore be delaying that process,” he noted. 

The other possibility is that adjuvants included in the recombinant vaccine to stimulate the immune system might have played a role. 

“We don’t have any data on the mechanism, and thus study did not address that, so further studies are needed to look into this,” Dr. Harrison said. 
 

Stronger Effect in Women

Another intriguing finding is that the association with the recombinant vaccine and delayed dementia diagnosis seemed to be stronger in women vs men. 

In the original study of the live shingles vaccine, a protective effect against dementia was shown only in women. 

In the current study, the delay in dementia diagnosis was seen in both sexes but was stronger in women, showing a 22% increased time without dementia in women versus a 13% increased time in men with the recombinant versus the live vaccine. 

As expected, the recombinant vaccine was associated with a lower risk for shingles disease vs the live vaccine (2.5% versus 3.5%), but women did not have a better response than men did in this respect. 

“The better protection against shingles with the recombinant vaccine was similar in men and women, an observation that might be one reason to question the possible mechanism behind the dementia effect being better suppression of the herpes zoster virus by the recombinant vaccine,” Dr. Harrison commented. 

Though these findings are not likely to lead to any immediate changes in policy regarding the shingles vaccine, Dr. Harrison said it would be interesting to see whether uptake of the vaccine increased after this study. 

He estimated that, currently in the United Kingdom, about 60% of older adults choose to have the shingles vaccine. A 2020 study in the United States found that only about one-third of US adults over 60 had received the vaccine. 

“It will be interesting to see if that figure increases after these data are publicized, but I am not recommending that people have the vaccine specifically to lower their risk of dementia because of the caveats about the study that we have discussed,” he commented. 
 

Outside Experts Positive 

Outside experts, providing comment to the Science Media Centre, welcomed the new research. 

“ The study is very well-conducted and adds to previous data indicating that vaccination against shingles is associated with lower dementia risk. More research is needed in future to determine why this vaccine is associated with lower dementia risk,” said Tara Spires-Jones, FMedSci, president of the British Neuroscience Association. 

The high number of patients in the study and the adjustments for potential confounders are also strong points, noted Andrew Doig, PhD, professor of biochemistry, University of Manchester, Manchester, England.

“This is a significant result, comparable in effectiveness to the recent antibody drugs for Alzheimer’s disease,” Dr. Doig said. “Administering the recombinant shingles vaccine could well be a simple and cheap way to lower the risk of Alzheimer’s disease.”

Dr. Doig noted that a link between herpes zoster infection and the onset of dementia has been suspected for some time, and a trial of the antiviral drug valacyclovir against Alzheimer’s disease is currently underway.

In regard to the shingles vaccine, he said a placebo-controlled trial would be needed to prove causality. 

“We also need to see how many years the effect might last and whether we should vaccinate people at a younger age. We know that the path to Alzheimer’s can start decades before any symptoms are apparent, so the vaccine might be even more effective if given to people in their 40s or 50s,” he said.

Dr. Harrison and Dr. Taquet reported no disclosures. Dr. Doig is a founder, director, and consultant for PharmaKure, which works on Alzheimer’s drugs and diagnostics. Other commentators declared no disclosures.

Youth with conduct disorder (CD) have extensive brain structure differences, new research showed.

In findings that illuminate the differences in areas of the brain critical for emotional processing and decision-making, investigators found lower cortical surface area and reduced volume in the limbic and striatal regions of the brain, as well as lower thalamus volume, in youth with CD.

“We know very little about this disorder even though it can carry a high burden for families and societies,” co–lead author Yidian Gao, PhD, of the University of Birmingham, Birmingham, England, said in a press release. 

“The sample included in our study is 10-20 times larger than previous studies and contains data on children from North America, Europe, and Asia. It provides the most compelling evidence to date that CD is associated with widespread structural brain differences,” he added.

The findings were published online in The Lancet Psychiatry.
 

An Understudied Disorder

In the largest study of its kind, researchers at the Universities of Bath and Birmingham, both in England, collaborated with research teams across Europe, North America, and Asia, as part of the Enhancing NeuroImaging Genetics through Meta-Analysis–Antisocial Behavior Working Group to learn more about one of the “least researched psychiatric disorders,” they wrote. 

The investigators used MRI to examine the brain structure of 1185 children with a clinical diagnosis of CD and 1253 typically developing children from 17-21 across 15 international study cohorts.

After adjusting for total intracranial volume investigators found that youth with CD (29% women; mean age, 13.7 years) had lower total surface area and lower regional surface area in 26 of the 34 cortical regions, spanning all four lobes of the brain, compared with their typically developing counterparts (35.6% women; mean age, 13.5 years).

Youth with CD also showed greater cortical thickness in the caudal anterior cingulate cortex (P = .0001) and lower cortical thickness in the banks of the superior temporal sulcus vs those without CD (P = .0010).

In addition, the CD group also had lower volume in the thalamus (P = .0009), amygdala (P = .0014), hippocampus (P = .0031), and nucleus accumbens (P = .0052). 

Most findings remained significant after adjusting for intelligence quotient, psychiatric comorbidities, and psychotropic medication use. Of note, group difference in cortical thickness, 22 of 27 differences in surface area. In addition, three of four subcortical differences remained robust after adjusting for co-occurring attention-deficit/hyperactivity disorder, the most frequent comorbidity.

When the investigators divided individuals with CD into two subgroups — those with high vs low levels of callous-unemotional traits — they found limited overall differences. However, those with high callous-unemotional traits had lower surface area in the superior temporal and superior frontal gyri vs those with low callous-unemotional traits and the typically developing group.

Investigators also found that individuals with childhood-onset CD had greater cortical thickness in the caudal anterior cingulate cortex compared with those with adolescent-onset CD. 

Study limitations include comparison of different cohorts with differing protocols that could affect the validity of the findings. In addition, subgroup samples were small and had lower statistical power.

“Our finding of robust brain alterations in conduct disorder — similar to those in more widely recognized and widely treated disorders such as ADHD — emphasize the need for a greater focus on conduct disorder in research, treatment, and public policy,” the authors noted.

Seven study authors reported conflicts of interest with various pharmaceutical companies and other organizations.

“Our finding of robust brain alterations in conduct disorder — similar to those in more widely recognized and widely treated disorders such as ADHD — emphasize the need for a greater focus on conduct disorder in research, treatment, and public policy,” the authors noted.

Seven study authors reported conflicts of interest with various pharmaceutical companies and other organizations.

TOPLINE:

Mental health disorders increase the likelihood of developing chronic diabetic complications and vice versa across all age groups in patients with type 1 diabetes (T1D) or type 2 diabetes (T2D).

METHODOLOGY:

• Understanding the relative timing and association between chronic diabetic complications and mental health disorders may aid in improving diabetes screening and care.
• Researchers used a US national healthcare claims database (data obtained from 2001 to 2018) to analyze individuals with and without T1D and T2D, who had no prior mental health disorder or chronic diabetic complication.
• The onset and presence of chronic diabetic complications and mental health disorders were identified to determine their possible association.
• Individuals were stratified by age: 0-19, 20-39, 40-59, and ≥ 60 years.

TAKEAWAY:

• Researchers analyzed 44,735 patients with T1D (47.5% women) and 152,187 with T2D (46.0% women), who were matched with 356,630 individuals without diabetes (51.8% women).
• The presence of chronic diabetic complications increased the risk for a mental health disorder across all age groups, with the highest risk seen in patients aged ≥ 60 years (hazard ratio [HR], 2.9).
• Similarly, diagnosis of a mental health disorder increased the risk for chronic diabetic complications across all age groups, with the highest risk seen in patients aged 0-19 years (HR, 2.5).
• Patients with T2D had a significantly higher risk for a mental health disorder and a lower risk for chronic diabetic complications than those with T1D across all age groups, except those aged ≥ 60 years.
• The bidirectional association between mental health disorders and chronic diabetic complications was not affected by the diabetes type (P > .05 for all interactions).

IN PRACTICE:

“Clinicians and healthcare systems likely need to increase their focus on MHDs [mental health disorders], and innovative models of care are required to optimize care for both individuals with type 1 diabetes and those with type 2 diabetes,” the authors wrote.

SOURCE:

The study, led by Maya Watanabe, Department of Biostatistics, University of Michigan, Ann Arbor, Michigan, was published online in Diabetes Care.

LIMITATIONS:

The study relied on International Classification of Diseases 9th and 10th revision codes, which might have led to misclassification of mental health conditions, chronic diabetes complications, and diabetes type. The data did not capture the symptom onset and severity. The findings may not be generalizable to populations outside the United States.

DISCLOSURES:

The study was supported by the Juvenile Diabetes Research Foundation (now Breakthrough T1D). Some authors reported receiving speaker or expert testimony honoraria and research support, and some declared serving on medical or digital advisory boards or as consultants for various pharmaceutical and medical device companies.

There has been an “alarming” increase in mental health hospital admissions involving methamphetamine use, new research showed. Investigators found that between 2008 and 2020, such admissions increased by more than 10-fold.

“Overall, our results show an alarming increase in mental health disorder–related hospitalizations with concurrent methamphetamine use from 2008 to 2020,” wrote the investigators, led by Diensn Xing, Department of Medicine, Louisiana State University Health Sciences Center, Shreveport.

“These results are especially concerning because these hospitalizations outpace hospitalizations for methamphetamine use alone or mental health disorders alone,” they added.

The study was published online in Nature Mental Health .
 

Action Needed

Mental illness and methamphetamine use are both growing health problems. The investigators pointed out that methamphetamine use can cause serious harm to an individual’s mental, emotional, and social well-being and can significantly alter the brain.

They added that long-term methamphetamine users can exhibit “extreme anxiety, confusion, troubled sleep, mood changes, and aggressive behavior.” In addition, use of the drug can cause psychotic side effects such as paranoia, hallucinations, delusions, and suicidality.

The investigators noted that, to date, no studies have examined the combined effects of both diseases or characterized national trends over more than 10 years.

The researchers analyzed US mental health–related trends in methamphetamine users from 2008 to 2020. In particular, they wanted to characterize which demographic and geographic groups might be affected by both of these diseases because people with mental illness and co-occurring methamphetamine use are an “intersectional group” that is “doubly vulnerable to suicide and overdose death due to the synergistic effects of methamphetamine and mental health disorders.”

The investigators evaluated US trends in mental health disorder–related hospital admissions (MHD-HAs) and compared them with mental health admissions that involved concurrent methamphetamine use (MHD-HA-MUs) between 2008 and 2020.

Using data from the largest US inpatient care database, which encompasses more than 7 million hospital stays annually, they examined close to 4 million weighted hospital admissions and found more than a 10-fold increase in MHD-HA-MUs, compared with a 1.4-fold increase in MHD-HAs.

MHD-HA-MUs increased significantly among men (13-fold), non-Hispanic Black patients (39-fold), and those aged 41-64 years (16-fold). In the southern United States, MHD-HA-MUs increased 24-fold, larger than in any other region in the United States.

“Overall, the data suggest that there are synergistic effects with methamphetamine use and mental health disorder, highlighting this patient group’s unique needs, requiring distinct action,” the researchers wrote.

They proposed several interventions, including public education about substance use disorders, mental illness, and the effects of stigma. They also suggested decreasing criminal penalties for those with substance use disorders and improving healthcare delivery for this patient population.

This work was supported by the National Institutes of Health and an award from the National Institute of General Medical Sciences. The study authors declared no relevant financial relationships.

An accelerated schedule of intermittent theta burst transcranial magnetic stimulation (aiTBS) completed in less than a week is effective for treatment-resistant bipolar depression, the results of a small randomized controlled trial showed.

Investigators found those who received active aiTBS had a substantial decrease in depressive symptoms compared with those who received sham stimulation.

“aiTBS offers a new potential therapy for depressed patients with bipolar disorder who may not respond well to drugs or cannot tolerate their side effects while also significantly shortening the treatment window,” lead researcher Yvette Sheline, MD, director of the Center for Neuromodulation in Depression and Stress at the University of Pennsylvania, Philadelphia, said in a news release.

The study was published online in JAMA Psychiatry.
 

Remission After 5 Days

The Food and Drug Administration (FDA) cleared aiTBS to treat major depressive disorder. However, the treatment is not yet approved for bipolar depression.

The investigators assessed the effectiveness of aiTBS in 12 men and 12 women (mean age, 43 years) with treatment-resistant bipolar disorder. All participants were on mood stabilizers for at least 4 weeks and had Montgomery-Åsberg Depression Rating Scale (MADRS) scores of 20 or greater.

Of the 24 participants, 22 had a diagnosis of bipolar II disorder. Over 5 days, participants were randomized to receive, on a 1:1 basis, 10 sessions per day of imaging-guided active aiTBS or sham aiTBS over the left dorsolateral prefrontal cortex. Each session lasted for 1 hour. All 24 participants completed the assigned treatment and 1-month follow-up.

Active aiTBS was significantly more effective than sham stimulation in relieving depressive symptoms.

In the active treatment group, MADRS scores dropped from a mean of 30.4 at baseline to 10.5 after treatment. In contrast, the sham group experienced a minor change in MADRS scores, which decreased from a mean of 28.0 at baseline to 25.3 posttreatment.

After 5 days of treatment, half of the participants in the active aiTBS group were in remission, compared with none in the sham group.

The results demonstrate the “clinical efficacy and a short time to achieve improvement in this difficult-to-treat condition. The effect was seen even though the participant sample had high depression severity and treatment resistance, both associated with poor response,” the investigators noted.

Dr. Sheline said there were no differences between active and sham stimulation in the “expected adverse events of headache and dizziness. There were no incidences of manic “flip,” and the Young Mania Rating Scale scores were stable in both active and sham groups with no difference between them.”

The researchers noted that the “large effect size” of active aiTBS could be caused by several factors, including optimized stimulation targeting, accelerated time course, and high pulse number (18,000 per day, 90,000 total).

Future studies are needed to examine the relative contributions of the different protocol components to optimize and personalize treatment and evaluate the durability of the antidepressant effects of aiTBS, they added.
 

A Revolutionary Approach

For comment on the study, we reached out to Nolan Williams, MD, associate professor of psychiatry and behavioral sciences at Stanford University and director of the Stanford Brain Stimulation Lab, Stanford, California.

His laboratory pioneered the Stanford Accelerated Intelligent Neuromodulation Therapy (SAINT), which was cleared by the FDA in 2022 for treatment-resistant depression.

Dr. Williams noted that the stimulation and targeting approach used in the current study “mirrors most aspects of the SAINT protocol with very similar results.”

“It’s exciting that we see this kind of pseudo-replication essentially of our work and is supportive of the general view that this approach is revolutionary in its ability to treat people quickly and have such a dramatic clinical effect,” said Dr. Williams.

In March 2024, Dr. Williams and colleagues reported the results of a pilot study of SAINT for bipolar depression, which demonstrated antidepressant efficacy akin to what was observed in the unipolar depression population.

Dr. Williams said, in his experience, the accelerated treatment protocol is convenient and well-liked by patients and, in general, is where the field of psychiatric treatment is headed.

“A general theme that we see in depression and psychiatry is that patients no longer accept long time frames for treatment as being the norm. Whether it be ketamine or this or the upcoming psychedelics, rapid-acting treatments that match the level of acuity will be the norm,” Dr. Williams said.

The study was funded by the Milken Institute and the Baszucki Brain Research Fund. The authors have disclosed no conflicts of interest. Dr. Williams is a named inventor on Stanford-owned intellectual property relating to accelerated TMS pulse pattern sequences and neuroimaging-based TMS targeting. He disclosed ties with Otsuka, NeuraWell, Magnus Medical, and Nooma.

TORONTO — Be suspicious if a child with a severe dermatologic condition is unresponsive to treatment, especially if their parent or caregiver exhibits deceptive behavior.

These could be red flags for Munchausen syndrome by proxy (MSBP), also known as factitious disorder.

“The No. 1 thing dermatologists can do in situations like this is be open to thinking outside the box and ask themselves the difficult question: Could this be something the parent is inflicting on the child,” Kelly Frasier, DO, a dermatology clinical trials and epidemiology research fellow at Northwell Health, Poughkeepsie, New York, said in an interview.

courtesy Pauline Anderson

She provided a review on advancing the understanding of the dermatologic manifestations of MSBP during a poster session at the annual meeting of the Society for Pediatric Dermatology (SPD). Dr. Frasier has a particular interest in psychodermatology — she was a mental health therapist before going to medical school.

MSBP is a type of abuse intentionally inflicted by a caregiver typically on their child “for some ulterior motive,” usually to seek attention or sympathy and not for material or financial gain, explained Dr. Frasier. People with MSBP seek medical help for exaggerated or fabricated symptoms in their child. They may alter medical tests, falsify medical records, or induce symptoms in their child.

To do this, these abusers may apply any number of caustic household products, including glue, directly to the child’s skin or even in formula. Dr. Frasier shared a picture of a baby whose formula had been doctored with a caustic substance that had dripped onto his neck and face, causing a rash with blisters.

In addition to blistering, cutaneous manifestations of MSBP can include severe bruising. Or the child may present with signs similar to those of granuloma annulare (a benign condition characterized by small, raised bumps) or cicatricial pemphigoid (a rare, chronic autoimmune blistering disorder) or may have recurrent nail avulsion, purpura, or coagulopathy, said Dr. Frasier.

In almost all cases of MSBP (an estimated 96%), the abuse is inflicted by the mother, who may have a preexisting mental illness. “Usually, a psychological disorder is at play, such as depression or anxiety,” said Dr. Frasier.

Some evidence suggests that, in cases of MSBP, the caregiver may have a personality disorder such as borderline or histrionic personality disorder — or may have suffered abuse or neglect as a child or is experiencing major stress, which some evidence suggests can trigger MSPB, she added.

This type of abuse is rarely seen in children older than 6 years, likely because they get wise to what’s going on and are better able to fight back or resist as they get older, Dr. Fraser noted.

High Mortality Rate

It’s critical that cases of MSBP are identified early. While a small proportion of child abuse cases involve MSBP, the mortality rate is extremely high, about 10%, research suggests, said Dr. Frasier.

Dermatologists should be skeptical if the child’s condition hasn’t improved despite trying numerous treatments that normally would have some effect. “If you’re doing everything you can to treat something that’s usually pretty simple in terms of what you normally see clinically and how you treat it, and you’re not seeing any improvement or things continue to get worse, that’s definitely a sign something else may be going on,” Dr. Frasier said.

Another suspicious sign is inflammation that continues “for weeks or months” and “doesn’t match up with actual lab markers and lab values,” said Dr. Frasier.

Other signs of possible MSBP include evidence of chemicals in the child’s blood, stool, or urine, or the child’s condition improves while in the hospital, but symptoms return after returning home.

Also be aware of the interaction between the parent and child, said Dr. Frasier. “See if you can pick up that something else might be going on, especially if the symptoms aren’t lining up very well with what you’re physically seeing and what your clinical impression is.”

And be suspicious of a parent’s inappropriate behavior; for example, they seem to be deliberately making symptoms worse or appear overly distraught. The seemingly caring parent could be overcompensating for what she’s doing at home, “and she wants to make sure it doesn’t appear that way,” said Dr. Frasier.

To help determine if some sort of trauma is occurring at home, the child would ideally be separated from the caregiver, perhaps with a nurse or other member of the interdisciplinary medical team, Dr. Frasier said.

It appears that pediatric dermatologists are already aware of the importance of protecting children from abuse. During a presentation at the meeting on child abuse and maltreatment in dermatology, not specifically on MSBP, Romy Cho, MD, assistant professor, Department of Pediatrics, University of Toronto, who is involved with the SCAN Program at The Hospital for Sick Children, Toronto, Canada, polled the audience on whether they had ever contacted child protective services (CPS). Almost 80% said they had.

That’s good news for Dr. Frasier. “We have to be willing to contact CPS if we think there’s something going on, and be more open to that because it’s better to be safe than sorry, especially in cases involving children.”

Dr. Frasier and Dr. Cho had no relevant disclosures.

TORONTO — Be suspicious if a child with a severe dermatologic condition is unresponsive to treatment, especially if their parent or caregiver exhibits deceptive behavior.

These could be red flags for Munchausen syndrome by proxy (MSBP), also known as factitious disorder.

“The No. 1 thing dermatologists can do in situations like this is be open to thinking outside the box and ask themselves the difficult question: Could this be something the parent is inflicting on the child,” Kelly Frasier, DO, a dermatology clinical trials and epidemiology research fellow at Northwell Health, Poughkeepsie, New York, said in an interview.

She provided a review on advancing the understanding of the dermatologic manifestations of MSBP during a poster session at the annual meeting of the Society for Pediatric Dermatology (SPD). Dr. Frasier has a particular interest in psychodermatology — she was a mental health therapist before going to medical school.

MSBP is a type of abuse intentionally inflicted by a caregiver typically on their child “for some ulterior motive,” usually to seek attention or sympathy and not for material or financial gain, explained Dr. Frasier. People with MSBP seek medical help for exaggerated or fabricated symptoms in their child. They may alter medical tests, falsify medical records, or induce symptoms in their child.

To do this, these abusers may apply any number of caustic household products, including glue, directly to the child’s skin or even in formula. Dr. Frasier shared a picture of a baby whose formula had been doctored with a caustic substance that had dripped onto his neck and face, causing a rash with blisters.

In addition to blistering, cutaneous manifestations of MSBP can include severe bruising. Or the child may present with signs similar to those of granuloma annulare (a benign condition characterized by small, raised bumps) or cicatricial pemphigoid (a rare, chronic autoimmune blistering disorder) or may have recurrent nail avulsion, purpura, or coagulopathy, said Dr. Frasier.

In almost all cases of MSBP (an estimated 96%), the abuse is inflicted by the mother, who may have a preexisting mental illness. “Usually, a psychological disorder is at play, such as depression or anxiety,” said Dr. Frasier.

Some evidence suggests that, in cases of MSBP, the caregiver may have a personality disorder such as borderline or histrionic personality disorder — or may have suffered abuse or neglect as a child or is experiencing major stress, which some evidence suggests can trigger MSPB, she added.

This type of abuse is rarely seen in children older than 6 years, likely because they get wise to what’s going on and are better able to fight back or resist as they get older, Dr. Fraser noted.

One in five children (20.2%) who have an older sibling with autism spectrum disorder (ASD) are likely to be diagnosed with the disorder as well, according to a study published in Pediatrics.

When a baby had more than one older sibling with autism, the family recurrence rate rose to 36.9%, the study found.

The researchers, led by Sally Ozonoff, PhD, Department of Psychiatry and Behavioral Sciences at University of California Davis Health in Sacramento, analyzed data from 1,605 infants who had an older sibling with ASD using data from the global Baby Siblings Research Consortium.

They calculated that the rate of autism recurrence is seven times higher in families who already have one autistic child than in the general population, which points to the importance of close developmental observance in infants born in families with autistic children, particularly male infants in those families. This study replicated a 2011 study, also led by Dr. Ozonoff, which found a similar rate of familial recurrence.
 

Differences by Sex and Race

Dr. Ozonoff’s team found that sex and race played a part in likelihood of recurrence. Younger siblings of females with ASD were much more likely to develop the disorder (34.7%) than siblings of boys (22.5%). And male younger siblings were more likely to have ASD than girls (25.3% vs. 13.1%).

Additionally, ASD recurrence in White families was 17.8% while across other races collectively the recurrence rate was 25%.
 

Links with Maternal Education

Differences by maternal education were also striking. Recurrence was 32.6% when mothers had a high school or less education; 25.5% with some college; 19.7 with a college degree; and 16.9% with a graduate degree. The parental education revealed a significant effect only for mothers (P < .01); paternal education was not significant (P = .09).

Suzanne Rybczynski, MD, chief medical officer at East Tennessee Children’s Hospital in Knoxville, who was not part of the study, praised the study for following babies over time, “doing serial evaluation using two very standard tools in diagnosing autism and developmental delay.”

The babies were evaluated as early as 6 months of age, for up to seven visits. A final assessment was made at 36 months.

Dr. Rybczynski said it was interesting to see that, although ASD prevalence has increased substantially from the 2011 study (0.9%-2.8%), the findings regarding the sibling link have been consistent (18.7% in the 2011 study to 20.2% now).
 

Eliminating Biases

Dr. Rybczynski noted the current study also used diagnoses only from autism experts, which strengthened the findings, noting the potential for overdiagnosis when interviews are with the parents. “This really eliminates those biases.”

The authors explained the factors driving the need to update recurrence rate studies, including the growth in the prevalence of ASD in the last decade to 1 in 36. That may be caused partly by “greater awareness and identification of autistic females and cognitively able, verbal children.”

Also, new diagnostic criteria have been published, with different diagnostic thresholds since the last study. This study, they noted, had a sample size twice as large and more diverse than the 2011 sample.

The size and the diversity are particularly important, Dr. Rybczynski said, as it helps support more recent findings that ASD is not as heavily centered in White males as previously thought.

“We need to make sure we’re monitoring all children, especially from groups where there’s at least one older sibling or multiple siblings with autism or a sister with autism,” she said. The findings of this study are important not just for pediatricians but for families and all who have professional interactions with children.

The start of the school year is a time that is always full of anticipation and even anxiety. Who will my teachers be? Will I be in classes with friends? Have some of my friends changed over the summer? Will the work be too hard? For some children this anxiety will be so intense that they will resist going back to school. School avoidance is very important to identify and address quickly, as it can intensify and threaten development. Each day of school missed due to accommodating to a child’s anxiety makes a return to school more difficult and less likely. Days can easily become weeks and even months of missed school. A child who misses a substantial amount of school is inevitably going to face developmental delays: academic, social, behavioral and emotional. The pediatrician is often brought into these situations early, as when a child complains of vague physical symptoms that are keeping him or her from school or when a previously calm child becomes inconsolable about going to school in the mornings. With a thoughtful assessment of the potential causes of school avoidance, you can help almost all children return to school successfully.

School Refusal

Sustained school avoidance is now called “school refusal,” a term coined in the late 1990s to describe a school attendance problem driven by emotional distress, as opposed to truancy. It affects up to 15% of children (depending on the operational definition) and seems to peak in the earliest years of elementary school and again in early high school. These are not occasional absences, but missing over 80% of classroom time in a 2-week period. It is also marked by the presence of an anxiety disorder and the absence of conduct disorder. Often in such cases the parents are aware of their child’s whereabouts and motivated to return them to school. Youth with school refusal experience social and academic consequences in the short term and, over the long term, have shown problems with social, family, and professional performance, along with higher rates of major depressive disorder than is seen in the general population. Early identification of these children can make addressing the underlying distress and return to school much easier than attempts to treat after weeks or months out of school.

Identifying the Problem

With younger children, school avoidance is most commonly associated with an anxious temperament or an underlying anxiety disorder, such as separation anxiety disorder or social phobia. A family history of anxiety may contribute or impact a parent’s approach to the issue. Children often present with vague somatic concerns that are genuine symptoms of anxiety (upset stomach, headache). A screening instrument such as the Screen for Child Anxiety Related Disorders (SCARED) can be helpful, but so is inquiring about sleep and other anxiety symptoms. Do the symptoms remit on weekends or in after-school hours? Are there other environmental factors that may be stressing younger children: Are they being teased or bullied at school? Are they struggling to find friends in a new classroom? Might they be having trouble with reading or other new tasks? Perhaps they are afraid of walking to school alone. Has there been a recent change or stress at home, such as a move or parental illness? Younger children may feel more anxious about separating from parents in the face of stress. But when parents accommodate a child’s wish to avoid school, the child’s anxiety, briefly relieved, grows more persistent, gets rewarded by parental attention, and reinforces their reluctance to try new things.

Adolescents may be facing more complex challenges that lead to school avoidance. They may have an undiagnosed anxiety or mood disorder, perhaps complicated by substance abuse that is presenting as an inability to perform at school or to manage the challenge of keeping up with higher workloads. They may be facing complex situations with friends, bullying, or rejection. Those adolescents who are prone to procrastination may avoid school to manage their workload and their distress, which can then become tangled up with symptoms of anxiety and dysphoria. Missing school compounds this problem rather than solving it. Adolescents outside of the structure of school, hungry for socializing and new experiences, often turn to social media for entertainment. Days without exercise and nights without adequate sleep can make mood, attention, and anxiety symptoms worse while overdue work grows. Parents often fear that setting limits or “pushing” their stuck and miserable child may make them more depressed or even suicidal.
 

Accommodating the Problem Will Likely Make It Worse

It is worth noting that children with a genuine medical illness can also experience school avoidance. Temperamentally anxious children who stay home for several days with a febrile illness may find it overwhelming to return to school as they have become so comfortable at home. Adolescents may have fallen behind with work and find themselves unable to set a schedule and return to more structure. Youth who are managing a known mood or anxiety disorder often have low motivation or high anxiety and want to wait to feel entirely better before returning to school. Youth with a chronic condition such as severe allergies or a sustained viral infection may be anxious about managing symptoms at school. Their parents may have kept them home to be safe or until they feel better, unwittingly making the school avoidance worse.

Formulating a Management Plan

When you suspect school avoidance is present, the critical first step is to engage the parents alongside their child. Without their understanding of the nature of this behavior, it will continue. Start by acknowledging the real physical and emotional symptoms their child is experiencing; it is important that parents and patients not feel that they are being told this is “just” a psychological problem. Children rarely feign illness or manipulate; they genuinely feel bad enough to stay home. It is important that they understand this is a common problem that will get worse unless it is addressed directly. If you believe they are suffering from a mood or anxiety disorder, talk about treatment options and consider getting started with treatment while finding a therapist to participate in their care. Help everyone listen to the child or teenager to understand any realistic basis for anxiety and attempt to address it (e.g. address bullying, provide a tutor, support a parent dependent on the child, etc.)

You can partner with parents and the school to provide the child with structure and support to make the return to school manageable. Frame the challenge of “demagnetizing” home and “remagnetizing” school. When they are at home, there should be no screen time except to catch up or keep up with homework. The child should not be in bed all day unless he or she has a fever. There needs to be close attention paid to maintaining a regular routine, with bedtime and wake time, meals with family, and regular exercise. This may mean turning off the Wi-Fi while a child is at home and parents are at work and providing them with books.

Work with the school to make getting into school and staying there as easy as possible. If a child has very high distress or has been out of school for a long time, he or she may need to return gradually; perhaps aim for the child to spend an hour at school for the first few days and then gradually work up to half and full days. Younger children may benefit from having a “buddy” who meets them outside and enters school with them. This can help avoid intense emotional scenes with parents that heighten distress and lead to accommodation. The child can identify a preferred teacher (or librarian, coach, or school nurse). When they feel overwhelmed, they can have a “break” with that teacher to avoid leaving school altogether. If they enjoy sports, music, or art, emphasize these classes or practices as part of their return to school.

Remind parents and your patients that it is not a matter of making the distress better first and then returning to school. They can be in treatment for an illness and manage returning to school at the same time. Indeed, the distress around school will only get better by getting back to school. This is hard! Ask about previous challenges they have managed or mastered and remind them that this is no different. Providing parents with knowledge and support will help them to be validating of their children without accommodating their wish to avoid discomfort. This support of your patient and the parents is the first step in helping them manage a difficult period and stay on their healthiest developmental trajectory.

Youth with school refusal experience social and academic consequences in the short term and, over the long term, have shown problems with social, family, and professional performance, along with higher rates of major depressive disorder than is seen in the general population. Early identification of these children can make addressing the underlying distress and return to school much easier than attempts to treat after weeks or months out of school.

Identifying the Problem

With younger children, school avoidance is most commonly associated with an anxious temperament or an underlying anxiety disorder, such as separation anxiety disorder or social phobia. A family history of anxiety may contribute or impact a parent’s approach to the issue. Children often present with vague somatic concerns that are genuine symptoms of anxiety (upset stomach, headache). A screening instrument such as the Screen for Child Anxiety Related Disorders (SCARED) can be helpful, but so is inquiring about sleep and other anxiety symptoms. Do the symptoms remit on weekends or in after-school hours? Are there other environmental factors that may be stressing younger children: Are they being teased or bullied at school? Are they struggling to find friends in a new classroom? Might they be having trouble with reading or other new tasks? Perhaps they are afraid of walking to school alone. Has there been a recent change or stress at home, such as a move or parental illness? Younger children may feel more anxious about separating from parents in the face of stress. But when parents accommodate a child’s wish to avoid school, the child’s anxiety, briefly relieved, grows more persistent, gets rewarded by parental attention, and reinforces their reluctance to try new things.

Adolescents may be facing more complex challenges that lead to school avoidance. They may have an undiagnosed anxiety or mood disorder, perhaps complicated by substance abuse that is presenting as an inability to perform at school or to manage the challenge of keeping up with higher workloads. They may be facing complex situations with friends, bullying, or rejection. Those adolescents who are prone to procrastination may avoid school to manage their workload and their distress, which can then become tangled up with symptoms of anxiety and dysphoria. Missing school compounds this problem rather than solving it. Adolescents outside of the structure of school, hungry for socializing and new experiences, often turn to social media for entertainment. Days without exercise and nights without adequate sleep can make mood, attention, and anxiety symptoms worse while overdue work grows. Parents often fear that setting limits or “pushing” their stuck and miserable child may make them more depressed or even suicidal.
 

Accommodating the Problem Will Likely Make It Worse

It is worth noting that children with a genuine medical illness can also experience school avoidance. Temperamentally anxious children who stay home for several days with a febrile illness may find it overwhelming to return to school as they have become so comfortable at home. Adolescents may have fallen behind with work and find themselves unable to set a schedule and return to more structure. Youth who are managing a known mood or anxiety disorder often have low motivation or high anxiety and want to wait to feel entirely better before returning to school. Youth with a chronic condition such as severe allergies or a sustained viral infection may be anxious about managing symptoms at school. Their parents may have kept them home to be safe or until they feel better, unwittingly making the school avoidance worse.

Formulating a Management Plan

When you suspect school avoidance is present, the critical first step is to engage the parents alongside their child. Without their understanding of the nature of this behavior, it will continue. Start by acknowledging the real physical and emotional symptoms their child is experiencing; it is important that parents and patients not feel that they are being told this is “just” a psychological problem. Children rarely feign illness or manipulate; they genuinely feel bad enough to stay home. It is important that they understand this is a common problem that will get worse unless it is addressed directly. If you believe they are suffering from a mood or anxiety disorder, talk about treatment options and consider getting started with treatment while finding a therapist to participate in their care. Help everyone listen to the child or teenager to understand any realistic basis for anxiety and attempt to address it (e.g. address bullying, provide a tutor, support a parent dependent on the child, etc.)

You can partner with parents and the school to provide the child with structure and support to make the return to school manageable. Frame the challenge of “demagnetizing” home and “remagnetizing” school. When they are at home, there should be no screen time except to catch up or keep up with homework. The child should not be in bed all day unless he or she has a fever. There needs to be close attention paid to maintaining a regular routine, with bedtime and wake time, meals with family, and regular exercise. This may mean turning off the Wi-Fi while a child is at home and parents are at work and providing them with books.

Work with the school to make getting into school and staying there as easy as possible. If a child has very high distress or has been out of school for a long time, he or she may need to return gradually; perhaps aim for the child to spend an hour at school for the first few days and then gradually work up to half and full days. Younger children may benefit from having a “buddy” who meets them outside and enters school with them. This can help avoid intense emotional scenes with parents that heighten distress and lead to accommodation. The child can identify a preferred teacher (or librarian, coach, or school nurse). When they feel overwhelmed, they can have a “break” with that teacher to avoid leaving school altogether. If they enjoy sports, music, or art, emphasize these classes or practices as part of their return to school.

Remind parents and your patients that it is not a matter of making the distress better first and then returning to school. They can be in treatment for an illness and manage returning to school at the same time. Indeed, the distress around school will only get better by getting back to school. This is hard! Ask about previous challenges they have managed or mastered and remind them that this is no different. Providing parents with knowledge and support will help them to be validating of their children without accommodating their wish to avoid discomfort. This support of your patient and the parents is the first step in helping them manage a difficult period and stay on their healthiest developmental trajectory.

The start of the school year is a time that is always full of anticipation and even anxiety. Who will my teachers be? Will I be in classes with friends? Have some of my friends changed over the summer? Will the work be too hard? For some children this anxiety will be so intense that they will resist going back to school. School avoidance is very important to identify and address quickly, as it can intensify and threaten development. Each day of school missed due to accommodating to a child’s anxiety makes a return to school more difficult and less likely. Days can easily become weeks and even months of missed school. A child who misses a substantial amount of school is inevitably going to face developmental delays: academic, social, behavioral and emotional. The pediatrician is often brought into these situations early, as when a child complains of vague physical symptoms that are keeping him or her from school or when a previously calm child becomes inconsolable about going to school in the mornings. With a thoughtful assessment of the potential causes of school avoidance, you can help almost all children return to school successfully.

School Refusal

Sustained school avoidance is now called “school refusal,” a term coined in the late 1990s to describe a school attendance problem driven by emotional distress, as opposed to truancy. It affects up to 15% of children (depending on the operational definition) and seems to peak in the earliest years of elementary school and again in early high school. These are not occasional absences, but missing over 80% of classroom time in a 2-week period. It is also marked by the presence of an anxiety disorder and the absence of conduct disorder. Often in such cases the parents are aware of their child’s whereabouts and motivated to return them to school. Youth with school refusal experience social and academic consequences in the short term and, over the long term, have shown problems with social, family, and professional performance, along with higher rates of major depressive disorder than is seen in the general population.

Individuals who are more active in the evening performed better on cognitive tests than did those who are typically more active in the morning hours, new research suggests. 

“Rather than just being personal preferences, these chronotypes could impact our cognitive function,” said study investigator, Raha West, MBChB, with Imperial College London, London, England, in a statement.

But the researchers also urged caution when interpreting the findings.

“It’s important to note that this doesn’t mean all morning people have worse cognitive performance. The findings reflect an overall trend where the majority might lean toward better cognition in the evening types,” Dr. West added. 

In addition, across the board, getting the recommended 7-9 hours of nightly sleep was best for cognitive function, and sleeping for less than 7 or more than 9 hours had detrimental effects on brain function regardless of whether an individual was a night owl or lark. 

The study was published online in BMJ Public Health. 
 

A UK Biobank Cohort Study 

The findings are based on a cross-sectional analysis of 26,820 adults aged 53-86 years from the UK Biobank database, who were categorized into two cohorts. 

Cohort 1 had 10,067 participants (56% women) who completed four cognitive tests measuring fluid intelligence/reasoning, pairs matching, reaction time, and prospective memory. Cohort 2 had 16,753 participants (56% women) who completed two cognitive assessments (pairs matching and reaction time).

Participants self-reported sleep duration, chronotype, and quality. Cognitive test scores were evaluated against sleep parameters and health and lifestyle factors including sex, age, vascular and cardiac conditions, diabetes,alcohol use, smoking habits, and body mass index.

The results revealed a positive association between normal sleep duration (7-9 hours) and cognitive scores in Cohort 1 (beta, 0.0567), while extended sleep duration negatively impacted scores across in Cohort 1 and 2 (beta, –0.188 and beta, –0.2619, respectively). 

An individual’s preference for evening or morning activity correlated strongly with their test scores. In particular, night owls consistently performed better on cognitive tests than early birds. 

“While understanding and working with your natural sleep tendencies is essential, it’s equally important to remember to get just enough sleep, not too long or too short,” Dr. West noted. “This is crucial for keeping your brain healthy and functioning at its best.”

Contrary to some previous findings, the study did not find a significant relationship between sleep, sleepiness/insomnia, and cognitive performance. This may be because specific aspects of insomnia, such as severity and chronicity, as well as comorbid conditions need to be considered, the investigators wrote. 

They added that age and diabetes consistently emerged as negative predictors of cognitive functioning across both cohorts, in line with previous research. 

Limitations of the study include the cross-sectional design, which limits causal inferences; the possibility of residual confounding; and reliance on self-reported sleep data.

Also, the study did not adjust for educational attainment, a factor potentially influential on cognitive performance and sleep patterns, because of incomplete data. The study also did not factor in depression and social isolation, which have been shown to increase the risk for cognitive decline.
 

No Real-World Implications

Several outside experts offered their perspective on the study in a statement from the UK nonprofit Science Media Centre. 

The study provides “interesting insights” into the difference in memory and thinking in people who identify themselves as a “morning” or “evening” person, Jacqui Hanley, PhD, with Alzheimer’s Research UK, said in the statement. 

However, without a detailed picture of what is going on in the brain, it’s not clear whether being a morning or evening person affects memory and thinking or whether a decline in cognition is causing changes to sleeping patterns, Dr. Hanley added. 

Roi Cohen Kadosh, PhD, CPsychol, professor of cognitive neuroscience, University of Surrey, Guildford, England, cautioned that there are “multiple potential reasons” for these associations. 

“Therefore, there are no implications in my view for the real world. I fear that the general public will not be able to understand that and will change their sleep pattern, while this study does not give any evidence that this will lead to any benefit,” Dr. Cohen Kadosh said. 

Jessica Chelekis, PhD, MBA, a sleep expert from Brunel University London, Uxbridge, England, said that the “main takeaway should be that the cultural belief that early risers are more productive than ‘night owls’ does not hold up to scientific scrutiny.” 

“While everyone should aim to get good-quality sleep each night, we should also try to be aware of what time of day we are at our (cognitive) best and work in ways that suit us. Night owls, in particular, should not be shamed into fitting a stereotype that favors an ‘early to bed, early to rise’ practice,” Dr. Chelekis said.
