Alzheimer’s and Epilepsy: Can Shared Molecular Mechanisms Reveal New Opportunities for Epilepsy?
ORLANDO — “
,” said Delia Marias Talos, MD, at a session of the annual meeting of the American Epilepsy Society (AES).A Closer Look at the Brain
“Phosphorylated tau correlates with cognitive function and executive function recorded presurgery, but it looks like the generative changes are more associated with temporal lobe and aging.”
Alzheimer’s disease is a degenerative condition marked by progressive memory deficits and cognitive decline noted by amyloid plaques and a formation of neurofibrillary tangles resulting from tau hyperphosphorylation.
Epilepsy, on the other hand, is a multifactorial condition with causes ranging from metabolic disorders, structural defects, infections, genetic mutations, and autoimmune disorders. In addition, nearly 50% of all epileptic seizures are idiopathic in nature.
Dr. Talos, professor of neurology at the University of Pennsylvania Perlman School of Medicine in Philadelphia, and her team did not see neurofibrillary tangles in the presurgical brains of epilepsy patients they studied; however, they saw tau plaques. In the future, they seek to investigate the features that distinguish epilepsy from Alzheimer’s disease.
Toxic fragments are probably there because amyloid precursor protein is highly upregulated, she told conference attendees. “We hypothesized that amyloid plaque is cleared but not impaired in epilepsy.”
The prognosis looks comparatively worse for patients who have Alzheimer’s disease and comorbid epilepsy than for patients who have only epilepsy. In addition, Dr. Talos stated that seizures appear to have an additive effort on Alzheimer’s disease.
Fyn-disruptive Therapy
Marson Putra, MD, PhD, a neuroscientist and postdoctoral researcher at Iowa State in Ames, Iowa, presented on the potential impact of a novel fyn-tau interaction as an unexplored target for epileptogensis and epilepsy.
Dr. Putra studied whether fyn-tau interactions exist in epilepsy. In both Alzheimer’s disease and epilepsy, Fyn belongs to the Src family of nonreceptor tyrosine kinases (SFKs), which are involved in cell proliferation and migration. Fyn contains an SH3 domain, which serves as a target for tau’s proline-rich (PxxP) motif. Fyn phosphorylates tau, specifically at tyrosine residue Y18, making fyn-disruptive therapy worth exploring.
Dr. Putra shared several currently proposed mechanisms of action regarding the pathogenesis of the tau plaque. In the first theory, the tau protein assumes a closed conformation in its normal state, thereby concealing the PxxP motif. However, in the second theory, pathogenesis causes the tau protein to assume an open conformation in the disease state, exposing pAT8 sites and making them available to fyn phosphorylation. In the second scenario, which involves Alzheimer’s disease, the fyn-tau interaction still occurs in open conformation state and is thought to occur in the postsynaptic terminal of the dendritic spine.
To investigate the proposed disease-causing mechanisms, Dr. Putra and her team studied status epilepticus in a rodent model of status epilepticus (SE). They used proximity ligation assay to measure interactions between Fyn and tau. They found AT8 and Y18 Fyn and N-methyl-D-aspartate (NMDA) receptor activation in a rat model and increased Fyn interaction. In addition, neuronal nitric oxide synthase levels were elevated 24 hours post-status. When investigating the fyn activity and interactions in the human brain, they found fyn phosphorylation – something that had never been reported before.
From there, Dr. Putra’s team sought to answer whether manipulating fyn-tau interactions could modify epilepsy. To do so, they conducted an experiment using the pharmacological Fyn inhibitor sarcatinib (SAR) and found it modified dysregulated postsynaptic proteins 24 hours post-SE in rat models. Longer exposure also bore a positive effect on epileptic rats.
After treating epileptic rats with SAR for 7 weeks, Dr. Putra found that SAR therapy reduces convulsive seizures during 7 weeks post-SE in rats. Recruiting pharmacological Fyn inhibition sufficiently decreased Fyn-tau interaction, NR-PSD95 complex, and convulsive seizures in chronic epilepsy.
Ultimately, her findings showed that SE exacerbates fyn-tau interactions, with chronic epilepsy modeling showing sustained elevation. In addition, fyn-tau interactions mediate and sustain neuronal hyperexcitability in the epileptic population.
“The impact on clinical care will be bidirectional relevant therapeutic targets in epilepsy and Alzheimer’s disease,” Dr. Putra told the audience.
Trends in epilepsy comorbidity and mortality
The final presenter, University of Washington researcher Aaron del Pozo, PhD, explained the impact of early-onset Alzheimer’s disease on overall outcomes and epilepsy.
“Early-onset Alzheimer’s disease carries a high seizure risk that affects quality of life as well as mortality,” Dr. del Pozo said.
According to data published in the British Medical Journal in 2020, the number of patients with epilepsy who had degenerative disease of the central nervous system or vascular dementia and delirium increased by approximately 210% from 1999 to 2017. Cerebral palsy trailed in second place with malignant neoplasms increasing by 50%. Cerebrovascular disease–related death in the epileptic population showed nearly negligible change, and ischemic heart disease and epilepsy decreased by approximately 25% and 15%, respectively. In addition, patients who have both epilepsy and Alzheimer’s disease are less likely to survive than patients who develop epilepsy after Alzheimer’s disease.
“We found that having epilepsy alone has decreased mortality, but having it in addition to other generative diseases of the central nervous system has a 200% increase in mortality,” Dr. del Pozo said.

FDA Gives Nod to Berdazimer Gel for Molluscum Contagiosum
On January 5, the Food and Drug Administration (FDA) approved berdazimer gel 10.3% for the treatment of molluscum contagiosum (MC) in adults and children aged 1 year or older.
Approval of berdazimer, a topical nitric oxide–releasing agent, was based largely on a 12-week pivotal phase 3 trial known as B-SIMPLE4, in which 891 patients with a mean age of 6.6 years (range, 0.9-47.5 years) were randomly assigned to treatment with berdazimer gel 10.3% or a vehicle gel applied in a thin layer to all lesions once daily. At 12 weeks, 32.4% of patients in the berdazimer group achieved complete clearance of MC lesions compared with 19.7% of those in the vehicle group (P < .001).
Only 4.1% of patients on berdazimer and 0.7% of those on the vehicle experienced adverse events that led to discontinuation of treatment. The most common adverse events in both groups were application-site pain and erythema, and most of these were mild or moderate.
According to a press release announcing the approval from Ligand Pharmaceuticals, which acquired berdazimer topical gel from Novan in September 2023, the development makes berdazimer topical gel 10.3% the first and only topical prescription medication that can be applied by patients, parents, or caregivers at home; outside of a physician›s office; or outside of other medical settings to treat MC. Nitric oxide has been shown to have antiviral effects, although the mechanism of action of berdazimer for treating molluscum “is unknown,” the company said in the release.
The drug will be marketed under the name Zelsuvmi and is expected to be available in the second half of 2024.
On July 21, 2023, topical cantharidin became the first approved treatment of MC for adults and pediatric patients aged 2 years or older, with the FDA approval of a drug-device combination (Ycanth) that contains a formulation of cantharidin solution 0.7% and is administered by healthcare professionals.

Eli Lilly Offers Obesity Drug Directly to Consumers
Eli Lilly, maker of the anti-obesity drug Zepbound, announced this week the launch of LillyDirect, a direct-to-patient portal, allowing some patients to obtain its drug for as little as $25 a month.
The move is seen as a major shift in the way these popular medications can reach patients.
For many of the 42 million Americans with obesity, weight loss medications such as Wegovy, Saxenda, and the brand-new Zepbound can be a godsend, helping them lose the excess pounds they’ve struggled with for decades or a lifetime.
But getting these medications has been a struggle for many who are eligible. Shortages of the drugs have been one barrier, and costs of up to $1,300 monthly — the price tag without insurance coverage — are another hurdle.
But 2024 may be a much brighter year, thanks to Lilly’s new portal as well as other developments:
Insurance coverage on private health plans, while still spotty, may be improving. Federal legislators are fighting a 2003 law that forbids Medicare from paying for the medications when prescribed for obesity.
New research found that semaglutide (Wegovy) can reduce the risk of recurrent strokes and heart attacks as well as deaths from cardiovascular events in those with obesity and preexisting cardiovascular disease (or diseases of the heart and blood vessels), a finding experts said should get the attention of health insurers.
The medications, also referred to as GLP-1 agonists, work by activating the receptors of hormones (called glucagon-like peptide 1 and others) that are naturally released after eating. That, in turn, makes you feel more full, leading to weight loss of up to 22% for some. The medications are approved for those with a body mass index (BMI) of 30 or a BMI of 27 with at least one other weight-related health condition such as high blood pressure or high cholesterol. The medicines, injected weekly or more often, are prescribed along with advice about a reduced-calorie diet and increased physical activity.
LillyDirect
Patients can access the obesity medicines through the telehealth platform FORM. Patients reach independent telehealth providers, according to Lilly, who can complement a patient’s current doctor or be an alternative to in-patient care in some cases.
Eli Lilly officials did not respond to requests for comment.
Some obesity experts welcomed the new service. “Any program that improves availability and affordability of these ground-breaking medications is welcome news for our long-suffering patients,” said Louis Aronne, MD, director of the Comprehensive Weight Control Center at Weill Cornell Medicine in New York City, a long-time obesity researcher.
“It’s a great move for Lilly to do,” agreed Caroline Apovian, MD, a professor of medicine at Harvard Medical School and co-director of the Center for Weight Management and Wellness at Brigham & Women’s Hospital in Boston, who is also a veteran obesity specialist. “It is trying to help the accessibility issue and do it responsibly.”
“The bottom line is, there is an overwhelming amount of consumer need and desire for these medications and not enough channels [to provide them],” said Zeev Neuwirth, MD, a former executive at Atrium Health who writes about health care trends. “Eli Lilly is responding to a market need that is out there and quite honestly continuing to grow.”
There are still concerns and questions, Dr. Neuwirth said, “especially since this is to my knowledge the first of its kind in terms of a pharmaceutical manufacturer directly dispensing medication in this nontraditional way.”
He called for transparency between telehealth providers and the pharmaceutical company to rule out any conflicts of interest.
The American College of Physicians, an organization of internal medicine doctors and others, issued a statement expressing concern. Omar T. Atiq, MD, group’s president, said his organization is “concerned by the development of websites that enable patients to order prescription medications directly from the drugmakers. While information on in-person care is available, this direct-to-consumer approach is primarily oriented around the use of telehealth services to prescribe a drug maker’s products.”
The group urged that an established patient-doctor relationship be present, or that care should happen in consultation with a doctor who does have an established relationship (the latter an option offered by Lilly). “These direct-to-consumer services have the potential to leave patients confused and misinformed about medications.”
Heart Attack, Stroke Reduction Benefits
Previous research has found that the GLP-1 medicines such as Ozempic (semaglutide), which the FDA approved to treat diabetes, also reduce the risk of cardiovascular issues such as strokes and heart attacks. Now, new research finds that semaglutide at the Wegovy dose (usually slightly higher than the Ozempic dose for diabetes) also has those benefits in those who don›t have a diabetes diagnosis but do have obesity and cardiovascular disease.
In a clinical trial sponsored by Novo Nordisk, the maker of Wegovy, half of more than 17,000 people with obesity were given semaglutide (Wegovy); the other half got a placebo. Compared to those on the placebo, those who took the Wegovy had a 20% reduction in strokes, heart attacks, and deaths from cardiovascular causes over a 33-month period.
The study results are a “big deal,” Dr. Aronne said. The results make it clear that those with obesity but not diabetes will get the cardiovascular benefits from the treatment as well. While more analysis is necessary, he said the important point is that the study showed that reducing body weight is linked to improvement in critical health outcomes.
As the research evolves, he said, it’s going to be difficult for insurers to deny medications in the face of those findings, which promise reductions in long-term health care costs.
Insurance Coverage
In November, the American Medical Association voted to adopt a policy to urge insurance coverage for evidence-based treatment for obesity, including the new obesity medications.
“No single organization is going to be able to convince insurers and employers to cover this,” Dr. Aronne said. “But I think a prominent organization like the AMA adding their voice to the rising chorus is going to help.”
Coverage of GLP-1 medications could nearly double in 2024, according to a survey of 500 human resources decision-makers released in October by Accolade, a personalized health care advocacy and delivery company. While 25% of respondents said they currently offered coverage when the survey was done in August and September, 43% said they intend to offer coverage in 2024.
In an email, David Allen, a spokesperson for America’s Health Insurance Plans, a health care industry association, said: “Every American deserves affordable coverage and high-quality care, and that includes coverage and care for evidence-based obesity treatments and therapies.”
He said “clinical leaders and other experts at health insurance providers routinely review the evidence for all types of treatments, including treatments for obesity, and offer multiple options to patients — ranging from lifestyle changes and nutrition counseling, to surgical interventions, to prescription drugs.”
Mr. Allen said the evidence that obesity drugs help with weight loss “is still evolving.”
“And some patients are experiencing bad effects related to these drugs such as vomiting and nausea, for example, and the likelihood of gaining the weight back when discontinuing the drugs,” he said.
Others are fighting for Medicare coverage, while some experts contend the costs of that coverage would be overwhelming. A bipartisan bill, the Treat and Reduce Obesity Act of 2023, would allow coverage under Medicare›s prescription drug benefit for drugs used for the treatment of obesity or for weigh loss management for people who are overweight. Some say it›s an uphill climb, citing a Vanderbilt University analysis that found giving just 10% of Medicare-eligible patients the drugs would cost $13.6 billion to more than $26 billion.
However, a white paper from the University of Southern California concluded that the value to society of covering the drugs for Medicare recipients would equal nearly $1 trillion over 10 years, citing savings in hospitalizations and other health care costs.
Comprehensive insurance coverage is needed, Dr. Apovian said. Private insurance plans, Medicare, and Medicaid must all realize the importance of covering what has been now shown to be life-saving drugs, she said.
Broader coverage might also reduce the number of patients getting obesity drugs from unreliable sources, in an effort to save money, and having adverse effects. The FDA warned against counterfeit semaglutide in December.
Long-Term Picture
Research suggests the obesity medications must be taken continuously, at least for most people, to maintain the weight loss. In a study of patients on Zepbound, Dr. Aronne and colleagues found that withdrawing the medication led people to regain weight, while continuing it led to maintaining and even increasing the initial weight loss. While some may be able to use the medications only from time to time, “the majority will have to take these on a chronic basis,” Dr. Aronne said.
Obesity, like high blood pressure and other chronic conditions, needs continuous treatment, Dr. Apovian said. No one would suggest withdrawing blood pressure medications that stabilize blood pressure; the same should be true for the obesity drugs, she said.
Dr. Apovian consults for FORM, the telehealth platform Lilly uses for LillyDirect, and consults for Novo Nordisk, which makes Saxenda and Wegovy. Dr. Aronne is a consultant and investigator for Novo Nordisk, Eli Lilly, and other companies.

Atiq, MD, group’s president, said his organization is “concerned by the development of websites that enable patients to order prescription medications directly from the drugmakers. While information on in-person care is available, this direct-to-consumer approach is primarily oriented around the use of telehealth services to prescribe a drug maker’s products.”
The group urged that an established patient-doctor relationship be present, or that care should happen in consultation with a doctor who does have an established relationship (the latter an option offered by Lilly). “These direct-to-consumer services have the potential to leave patients confused and misinformed about medications.”
Heart Attack, Stroke Reduction Benefits
Previous research has found that the GLP-1 medicines such as Ozempic (semaglutide), which the FDA approved to treat diabetes, also reduce the risk of cardiovascular issues such as strokes and heart attacks. Now, new research finds that semaglutide at the Wegovy dose (usually slightly higher than the Ozempic dose for diabetes) also has those benefits in those who don›t have a diabetes diagnosis but do have obesity and cardiovascular disease.
In a clinical trial sponsored by Novo Nordisk, the maker of Wegovy, half of more than 17,000 people with obesity were given semaglutide (Wegovy); the other half got a placebo. Compared to those on the placebo, those who took the Wegovy had a 20% reduction in strokes, heart attacks, and deaths from cardiovascular causes over a 33-month period.
The study results are a “big deal,” Dr. Aronne said. The results make it clear that those with obesity but not diabetes will get the cardiovascular benefits from the treatment as well. While more analysis is necessary, he said the important point is that the study showed that reducing body weight is linked to improvement in critical health outcomes.
As the research evolves, he said, it’s going to be difficult for insurers to deny medications in the face of those findings, which promise reductions in long-term health care costs.
Insurance Coverage
In November, the American Medical Association voted to adopt a policy to urge insurance coverage for evidence-based treatment for obesity, including the new obesity medications.
“No single organization is going to be able to convince insurers and employers to cover this,” Dr. Aronne said. “But I think a prominent organization like the AMA adding their voice to the rising chorus is going to help.”
Coverage of GLP-1 medications could nearly double in 2024, according to a survey of 500 human resources decision-makers released in October by Accolade, a personalized health care advocacy and delivery company. While 25% of respondents said they currently offered coverage when the survey was done in August and September, 43% said they intend to offer coverage in 2024.
In an email, David Allen, a spokesperson for America’s Health Insurance Plans, a health care industry association, said: “Every American deserves affordable coverage and high-quality care, and that includes coverage and care for evidence-based obesity treatments and therapies.”
He said “clinical leaders and other experts at health insurance providers routinely review the evidence for all types of treatments, including treatments for obesity, and offer multiple options to patients — ranging from lifestyle changes and nutrition counseling, to surgical interventions, to prescription drugs.”
Mr. Allen said the evidence that obesity drugs help with weight loss “is still evolving.”
“And some patients are experiencing bad effects related to these drugs such as vomiting and nausea, for example, and the likelihood of gaining the weight back when discontinuing the drugs,” he said.
Others are fighting for Medicare coverage, while some experts contend the costs of that coverage would be overwhelming. A bipartisan bill, the Treat and Reduce Obesity Act of 2023, would allow coverage under Medicare›s prescription drug benefit for drugs used for the treatment of obesity or for weigh loss management for people who are overweight. Some say it›s an uphill climb, citing a Vanderbilt University analysis that found giving just 10% of Medicare-eligible patients the drugs would cost $13.6 billion to more than $26 billion.
However, a white paper from the University of Southern California concluded that the value to society of covering the drugs for Medicare recipients would equal nearly $1 trillion over 10 years, citing savings in hospitalizations and other health care costs.
Comprehensive insurance coverage is needed, Dr. Apovian said. Private insurance plans, Medicare, and Medicaid must all realize the importance of covering what has been now shown to be life-saving drugs, she said.
Broader coverage might also reduce the number of patients getting obesity drugs from unreliable sources, in an effort to save money, and having adverse effects. The FDA warned against counterfeit semaglutide in December.
Long-Term Picture
Research suggests the obesity medications must be taken continuously, at least for most people, to maintain the weight loss. In a study of patients on Zepbound, Dr. Aronne and colleagues found that withdrawing the medication led people to regain weight, while continuing it led to maintaining and even increasing the initial weight loss. While some may be able to use the medications only from time to time, “the majority will have to take these on a chronic basis,” Dr. Aronne said.
Obesity, like high blood pressure and other chronic conditions, needs continuous treatment, Dr. Apovian said. No one would suggest withdrawing blood pressure medications that stabilize blood pressure; the same should be true for the obesity drugs, she said.
Dr. Apovian consults for FORM, the telehealth platform Lilly uses for LillyDirect, and consults for Novo Nordisk, which makes Saxenda and Wegovy. Dr. Aronne is a consultant and investigator for Novo Nordisk, Eli Lilly, and other companies.

Eli Lilly, maker of the anti-obesity drug Zepbound, announced this week the launch of LillyDirect, a direct-to-patient portal, allowing some patients to obtain its drug for as little as $25 a month.
The move is seen as a major shift in the way these popular medications can reach patients.
For many of the 42 million Americans with obesity, weight loss medications such as Wegovy, Saxenda, and the brand-new Zepbound can be a godsend, helping them lose the excess pounds they’ve struggled with for decades or a lifetime.
But getting these medications has been a struggle for many who are eligible. Shortages of the drugs have been one barrier, and costs of up to $1,300 monthly — the price tag without insurance coverage — are another hurdle.
But 2024 may be a much brighter year, thanks to Lilly’s new portal as well as other developments:
Insurance coverage on private health plans, while still spotty, may be improving. Federal legislators are fighting a 2003 law that forbids Medicare from paying for the medications when prescribed for obesity.
New research found that semaglutide (Wegovy) can reduce the risk of recurrent strokes and heart attacks as well as deaths from cardiovascular events in those with obesity and preexisting cardiovascular disease (or diseases of the heart and blood vessels), a finding experts said should get the attention of health insurers.
The medications, also referred to as GLP-1 agonists, work by activating the receptors of hormones (called glucagon-like peptide 1 and others) that are naturally released after eating. That, in turn, makes you feel more full, leading to weight loss of up to 22% for some. The medications are approved for those with a body mass index (BMI) of 30 or a BMI of 27 with at least one other weight-related health condition such as high blood pressure or high cholesterol. The medicines, injected weekly or more often, are prescribed along with advice about a reduced-calorie diet and increased physical activity.
LillyDirect
Patients can access the obesity medicines through the telehealth platform FORM. Patients reach independent telehealth providers, according to Lilly, who can complement a patient’s current doctor or be an alternative to in-patient care in some cases.
Eli Lilly officials did not respond to requests for comment.
Some obesity experts welcomed the new service. “Any program that improves availability and affordability of these ground-breaking medications is welcome news for our long-suffering patients,” said Louis Aronne, MD, director of the Comprehensive Weight Control Center at Weill Cornell Medicine in New York City, a long-time obesity researcher.
“It’s a great move for Lilly to do,” agreed Caroline Apovian, MD, a professor of medicine at Harvard Medical School and co-director of the Center for Weight Management and Wellness at Brigham & Women’s Hospital in Boston, who is also a veteran obesity specialist. “It is trying to help the accessibility issue and do it responsibly.”
“The bottom line is, there is an overwhelming amount of consumer need and desire for these medications and not enough channels [to provide them],” said Zeev Neuwirth, MD, a former executive at Atrium Health who writes about health care trends. “Eli Lilly is responding to a market need that is out there and quite honestly continuing to grow.”
There are still concerns and questions, Dr. Neuwirth said, “especially since this is to my knowledge the first of its kind in terms of a pharmaceutical manufacturer directly dispensing medication in this nontraditional way.”
He called for transparency between telehealth providers and the pharmaceutical company to rule out any conflicts of interest.
The American College of Physicians, an organization of internal medicine doctors and others, issued a statement expressing concern. Omar T. Atiq, MD, group’s president, said his organization is “concerned by the development of websites that enable patients to order prescription medications directly from the drugmakers.

Do Statins Offset Venous Thrombosis Risk With Hormone Therapy?
This transcript has been edited for clarity.
This is Dr JoAnn Manson, professor of medicine at Harvard Medical School and Brigham and Women’s Hospital. I’d like to talk with you about a recent report in JAMA Network Open on the subject of whether statin therapy may be able to offset some of the excess risk for venous thromboembolism (VTE) among women taking menopausal hormone therapy.
It’s an important issue because we know that menopausal hormone therapy, especially oral therapy, is linked to an excess risk for VTE, approximately doubling of risk in the randomized clinical trials. There is also emerging evidence from some randomized trials, such as the Jupiter trial, that step therapy may be linked to a reduction in risk. This may be related to anti-inflammatory or antithrombotic effects of statin therapy.
The authors made use of a very large administrative claims database, Optum Health, to look at more than 15 million annual members. They were able to identify 2000 women with a diagnostic code for VTE treatment. The women were between ages 50 and 64 years, and they were compared with 200,000 controls without VTE, matched in 10-to-1 fashion.
About 50% of the women were taking oral hormone therapy, and about 50% took non-oral transdermal or other non-oral formulations of hormone therapy. The odds ratio for VTE was 1.53 among the women who did not also have prescription records for statin therapy. They were able to look at prescribed prescriptions for both the hormone therapy and the statins. Among the women prescribed hormone therapy and also low- to intermediate-dose statins, the odds ratio was 1.29. So that was quite a mitigation of the elevated risk. Among the women taking high-intensity statins, the odds ratio was 1.06, and there was no significant elevation.
We do need more data and more research on this question. One approach would be a meta-analysis of all of the existing randomized trials of hormone therapy in recent years wherein there was increased uptake of statin therapy to look at this question not only for VTE but also for coronary heart disease, stroke, and other CVD outcomes to see whether statin therapy is associated with some attenuation of the excess risk. We also need a targeted randomized trial of statins vs placebo among women who have clear indications for hormone therapy but may be at some increased risk for VTE. That type of trial would be extremely helpful.
These include choosing a transdermal rather than an oral formulation of hormone therapy and using lower doses of hormone therapy. Also, women who are clear candidates for hormone therapy and also for statins, it’s obvious that statins could be co-prescribed. Even among women who are clear candidates for hormone therapy but only intermediate borderline candidates for statin therapy, the prescription of statins might be considered in that clinical scenario to try to mitigate that excess risk for VTE.
JoAnn E. Manson, MD, DrPH, has disclosed the following relevant financial relationships: Received study pill donation and infrastructure support from: Mars Symbioscience (for the COSMOS trial).

Noninvasive Brain Stimulation a Breakthrough for Hypnotherapy?
Less than 2 minutes of transcranial magnetic stimulation (TMS) targeting specific areas of the brain can boost an individual’s ability to be hypnotized, in new findings that could increase the efficacy of therapeutic hypnosis and expand the pool of patients who can benefit from it.
“We were able to increase hypnotizability, a neuropsychological trait previously shown to be as stable as IQ in adulthood,” said co-senior author David Spiegel, MD, professor of psychiatry and behavioral sciences, Stanford University, Palo Alto, California.
“Our findings would allow us to combine neurostimulation with hypnosis to expand the number of people able to benefit from hypnosis and enhance their responsiveness to treatment,” Dr. Spiegel added.
The study was published online on January 4, 2024, in Nature Mental Health.
A Breakthrough for Hypnotherapy?
About two thirds of the general adult population are estimated to be at least somewhat hypnotizable, and 15% are highly hypnotizable.
Through brain imaging, the Stanford team found that high hypnotizability is associated with greater functional connectivity between the left dorsolateral prefrontal cortex (DLPFC) and the dorsal anterior cingulate cortex.
In the double-blind study, they randomly assigned 80 patients (mean age, 48 years; 94% women) with fibromyalgia syndrome to active, or sham, continuous theta-burst stimulation over a personalized neuroimaging-derived left DLPFC target — a technique known as Stanford Hypnosis Integrated with Functional Connectivity-targeted Transcranial Stimulation (SHIFT). Individuals who were naturally highly hypnotizable were excluded.
“A novel aspect of this trial is that we used the person’s own brain networks, based on brain imaging, to target the right spot,” Co-senior author Nolan Williams, MD, with Stanford University, California, said in a news release.
The team chose patients with chronic pain because hypnosis has been shown to be a “highly effective analgesic that has a far better risk/benefit ratio than widely overutilized opioids that have serious fatal overdose potential,” Spiegel told this news organization.
The pre-to-post SHIFT change in hypnotic induction profile scores, a standardized measure of hypnotizability, was significantly greater in the active vs sham group after just 92 seconds of stimulation (P = .046).
Only the active SHIFT group showed a significant increase in hypnotizability following stimulation, an effect that lasted for about 1 hour.
“Increasing hypnotizability in people who are low-to-medium hypnotizable individuals could improve both the efficacy and effectiveness of therapeutic hypnosis as a clinical intervention,” the researchers wrote.
They note that because this was a “mechanistic study,” it did not explore the impact of increased hypnotizability on disease symptoms. They also note that further studies are needed to assess the dose-response relationships of SHIFT.
Transformative Research
“This line of research is fascinating,” Shaheen Lakhan, MD, PhD, neurologist, and researcher in Boston, told this news organization.
“We are nearing an era of personalized, noninvasive brain modulation. The ability to individually modulate the DLPFC opens new possibilities for brain health beyond hypnotizability for fibromyalgia,” said Dr. Lakhan, who wasn’t involved in the study.
“The DLPFC is involved in executive functions (and disorders) like attention (ADHD), emotional regulation (depression), motivation (schizophrenia), and impulse control (addiction),” he noted.
“Soon we may no longer need large expensive devices like transcranial magnetic stimulators as in this research study. Smartphones could deliver tailored digital therapeutics by engaging specific brain circuits,” Dr. Lakhan predicted.
“Imagine using an app to receive treatment customized to your unique brain and needs — all without anything implanted and delivered anywhere. The potential to precisely modulate the brain’s wiring to enhance cognition and mental health, without surgery or physical constraints, is incredibly promising. The possibilities are intriguing and could truly transform how we address brain diseases,” he added.
The study was supported by a grant from the National Center for Complementary and Integrative Health (NCCIH), part of the National Institutes of Health (NIH). Dr. Williams is a named inventor on Stanford-owned intellectual property relating to accelerated TMS pulse pattern sequences and neuroimaging-based TMS targeting; has served on scientific advisory boards for Otsuka, NeuraWell, Magnus Medical, and Nooma as a paid advisor; and holds equity/stock options in Magnus Medical, NeuraWell, and Nooma.

“This line of research is fascinating,” Shaheen Lakhan, MD, PhD, neurologist, and researcher in Boston, told this news organization.
“We are nearing an era of personalized, noninvasive brain modulation. The ability to individually modulate the DLPFC opens new possibilities for brain health beyond hypnotizability for fibromyalgia,” said Dr. Lakhan, who wasn’t involved in the study.
“The DLPFC is involved in executive functions (and disorders) like attention (ADHD), emotional regulation (depression), motivation (schizophrenia), and impulse control (addiction),” he noted.
“Soon we may no longer need large expensive devices like transcranial magnetic stimulators as in this research study. Smartphones could deliver tailored digital therapeutics by engaging specific brain circuits,” Dr. Lakhan predicted.
“Imagine using an app to receive treatment customized to your unique brain and needs — all without anything implanted and delivered anywhere. The potential to precisely modulate the brain’s wiring to enhance cognition and mental health, without surgery or physical constraints, is incredibly promising. The possibilities are intriguing and could truly transform how we address brain diseases,” he added.
The study was supported by a grant from the National Center for Complementary and Integrative Health (NCCIH), part of the National Institutes of Health (NIH). Dr. Williams is a named inventor on Stanford-owned intellectual property relating to accelerated TMS pulse pattern sequences and neuroimaging-based TMS targeting; has served on scientific advisory boards for Otsuka, NeuraWell, Magnus Medical, and Nooma as a paid advisor; and holds equity/stock options in Magnus Medical, NeuraWell, and Nooma. Dr. Spiegel is a cofounder of Reveri Health, Inc., an interactive hypnosis app (not utilized in the current study).

A Counterintuitive Approach to Lowering Cholesterol in Children
With the flip of the calendar a few short weeks ago, gyms and fitness centers began ramping up their advertising campaigns in hopes of attracting the horde of resolution makers searching for a place where they can inject some exercise into their sedentary lives. A recent survey by C.S. Mott’s Children’s Hospital found that even young people are setting health-related goals with more than half of the parents of 11- to 18-year-olds reporting their children were setting personal goals for themselves. More than 40% of the young people listed more exercise as a target.
However, our personal and professional experiences have taught us that achieving goals, particularly when it comes to exercise, is far more difficult than setting the target. Finding an exercise buddy can be an important motivator on the days when just lacing up one’s sneakers is a stumbling block. Investing in a gym membership and sweating with a peer group can help. However, it is an investment that rarely pays a dividend. Exercise isn’t fun for everyone. For adults, showing up at a gym may be just one more reminder of how they have already lost their competitive edge over their leaner and fitter peers. If they aren’t lucky enough to find a sport or activity that they enjoy, the loneliness of the long-distance runner has little appeal.
A recent study on children in the United Kingdom suggests that at least when it comes to teens and young adults we as physicians may actually have been making things worse for our obese patients by urging them to accept unrealistic activity goals. While it is already known that sedentary time is responsible for 70% of the total increase in cholesterol as children advance to young adulthood an unqualified recommendation for more exercise may not be the best advice.
In an interview with the study author, Andre O. Agbaje MD, MPH, said that in his large study population “light physical activity outperforms moderate to vigorous physical activity by five to eight times in lowering lipids”. While we may be surprised by this counterintuitive finding, Dr. Agbaje points out that an increase in sedentariness from 6 to 9 hours per day translates into a loss of 3 hours of light physical activity. In other words if you’re not sedentary you must be standing at attention or engaged in some light activity.
In my experience, and I suspect yours, it is difficult to get adults to do something, particularly if that something involves exerting energy, even a small amount of energy. The general admonishment of “be more active” is often met with a blank stare and the sometimes unspoken question “Like what?”
You could fall into a bottomless trap with them by suggesting a long list of activities, many of which are probably ones you do or would enjoy but don’t happen to fit with any of their interests or capabilities. Your chances of hitting on a perfect activity that the patient will attempt, let alone adopt, is very slim. Those of you with more patience than I have may choose to persist with this strategy. You could argue that even if the patient only dabbles briefly in one of your recommended activities, this is a minor victory worth celebrating. Who knows? The brief jolt of energy they received from this activity may prompt them to seek and find something else that works.
My interpretation of Dr. Agbaje’s findings is this: If we are going to suggest more activity, aim low. Don’t even mention the heavily weighted words “sport” or “exercise,” which are likely to dredge up bad memories. For adults, “Go shopping” or “Visit a friend” may be sufficient to at least get the person off the couch and on their feet and moving, even if very briefly.
The second message from this study applies more to children and adolescents and is one of those unusual instances in which a negative intervention may be more effective than a positive approach. Acknowledging that we are likely to have difficulty finding even a light activity that the child enjoys, why not pivot to the other side of the equation? Make a list of the child’s primary sedentary “activities.” Then suggest the parents put the child on a couch potato diet by immediately cutting in half the time he or she spends being sedentary. By definition, this will automatically increase his or her light physical activity by 50%. According to Dr. Agbaje’s data, this should be more effective in lowering lipids than in the unlikely event of finding a moderate activity the child accepts.
You can argue that the child will hound his or her parents unmercifully asking to be entertained. This may be true and this persistent complaining will be more likely to come from the older the child and the longer that the child has been allowed to be sedentary. Although the child may appear to have lost the ability to self amuse, I contend this isn’t a permanent loss and, This is another example of how saying “No!” in the right circumstances is often the most effective remedy for an unhealthy situation. I would never claim saying “No” is easy and helping parents to learn how to say “No” is one of our most difficult challenges. But, nothing else seems to be working.

Healthcare Violence: Doctors and Nurses Are Bearing the Brunt of Business Pressures
This transcript has been edited for clarity.
This month, I want to tackle the difficult subject of violence toward healthcare workers. There’s a reason this is top of mind for me in my practice, but I want to start by acknowledging that this has been a much larger issue for our profession and one that has been growing for a number of years now.
They also estimate that that rate doubled between 2011 and 2018. I think that range is important because it proves this was a problem, and a crescendoing problem, even before COVID.
Another thing I think is relevant is to look at where in the healthcare system are these attacks most likely. In the emergency room, ER staff have seen hostility toward them rise by at least 25% over the past several years. Some of the seeds of mistrust that were sown between the general public and the scientific and medical communities around the pandemic. I think there’s some explanation there for why that might be a particular crucible.
Perhaps most disturbingly of all, 60% of the victims of healthcare workplace violence are bedside nurses. There is something about the intensity of the inpatient setting that makes nerves particularly frayed and unfortunately makes patients and family members more likely to lash out. I think it’s actually the heightened sense of mortality.
I’m not excusing any of these behaviors, but maybe it’s akin to road rage. On the road, behind the wheel, tiny gestures can actually be, on some level, perceived as threats to our survival. Another driver swerving into your lane activates a fight-or-flight response, you feel threatened, and you might respond in the moment very rashly. I wonder if we’re not seeing that, quite unfairly, play out against bedside staff in our hospitals.
Here’s the thing. Those of us who practice in the outpatient setting — 95% of my work, for instance, happens in clinic — are not immune to this either. There are some very harrowing recent examples of physicians being killed, typically at gunpoint, often by patients, sometimes by aggrieved family members, in their offices. An orthopedist in Tennessee, a back surgeon in Tulsa, along with three of their colleagues. In the latter case, the assailant specifically blamed the surgeon for their pain.
This is where I think things get even more scary. We have to be the bearers of bad news in our profession. This has long been the task of the oncologist, in particular, to convey things that people don’t want to hear.
I think what brought this to my mind in terms of my reading was an incredible article in The ASCO Post and also in the Journal of Clinical Oncology by Dr. Noelle LoConte, who’s a medical oncologist in Wisconsin. The article is called, “I Want to Kill You,” and it recounts her telling a previously stage III colon cancer patient, with whom she thought she had good rapport, that the disease had recurred. The patient’s immediate reaction in the heat of that moment was to say, Dr LoConte, I want to kill you. I want to blow your face off.
Already, there’s clearly tension when we are telling people what they don’t want to hear. I think the final piece of the puzzle goes back to the intrusion of the business of healthcare on the practice of medicine. This is what I witnessed very recently. One of the things that’s interesting to think about is how what we do is now framed as customer service. I know there’s deriding of this model, but if perception is reality, we have a system where patients are set up to view themselves as consumers.
Let’s say, for instance, you’re in the unfortunate circumstance of being diagnosed with cancer and your insurer gives you the option to go to multiple oncologists. If you’re online browsing for oncologists, how do you differentiate me from some of my colleagues? The answer on these rating websites often has to do with domains that are about the overall experience — not just the patient-doctor interaction but also things like wait time, friendliness of staff, and promptness of care delivery.
That, I think, is the final piece of the puzzle, because what I really risk when I sit down with a patient and lay out a treatment plan is overpromising and underdelivering. I am long used to citing median overall survival for expectation of outcome. Of course, every patient wants to be an exceptional responder. Most patients want to be on the latter half of median survival. No one wants to be on the disappointingly shorter half.
My point is that I’ve long been able to mitigate that uncertainty for patients. What is getting harder and harder to explain away is the delay incurred between someone’s diagnosis, my meeting them and laying out a treatment plan, and their actual initiation of that therapy.
This finally brings me to my recent personal encounter. I have long taken care of a patient, much like Dr LoConte’s, with an extremely calm demeanor. I thought we had a great therapeutic alliance. I had to tell the patient that the disease had recurred, and then I laid out a treatment plan. It took weeks and then months for the insurer to approve this plan despite my providing my note in a timely fashion with a mountain of evidence behind the regimen that I’d selected.
This is where I think insurers — when they deny, deflect, and delay — are not taking adequate responsibility for the impact that has on the therapeutic alliance between a patient and their doctor. These people are trusting us with their lives. As an oncologist, I’ve already told them something they didn’t want to hear, and now I’m compounding that with the uncertainty of when we can actually begin treatment.
This gentleman — who, again, is normally extremely kind and affable — showed up at my office and was incredibly hostile toward me and my staff because of the delay that he was encountering. We literally couldn’t tell him when his insurer was going to approve his treatment, which would have been financially disastrous if he had tried to pay for it himself out of pocket. He needed his insurer’s approval before we could start, but we didn’t know when he could start. That uncertainty and not knowing was gnawing away at him until he was at the end of his rope.
What I’m here to say is that this has been a difficult couple of years in healthcare. I’m well aware that our ER staff are on the front lines, as are our bedside and inpatient teams. Even in the outpatient setting, I think we’re seeing this crucible and we’re seeing the pressure just grow, and grow, and grow. It’s like fracking. The more you increase the pressure, the more eventually you’re going to find out where the cracks are.
These patients are the ultimate stakeholders. It’s their lives on the line, and we should be concerned, but perhaps ultimately not surprised, that they’re lashing out to be heard. Given no other resort, they are taking out their frustration and their aggression on us. It›s not fair, but I am newly aware of it because, in a patient with whom I thought we had a superb rapport, I saw that vanish. As soon as he thought that his life was at risk, his fight-or-flight response kicked in. I was not dealing with the same man I knew. I was dealing with someone who was desperate and who just wanted to know when he could get the treatment.
I think this has taken the likelihood of workplace hostility to a whole other level for those of us in healthcare.
For any patients listening, I beg of you, please don’t shoot the messenger. We are here to serve you the best we can, but there are many external factors at play. We are doing our best to mitigate those for you so we can deliver the care that we promised in as timely a fashion as we can.
I hope everyone out there can stay safe. Thank you.

This is where I think things get even more scary. We have to be the bearers of bad news in our profession. This has long been the task of the oncologist, in particular, to convey things that people don’t want to hear.
I think what brought this to my mind in terms of my reading was an incredible article in The ASCO Post and also in the Journal of Clinical Oncology by Dr. Noelle LoConte, who’s a medical oncologist in Wisconsin. The article is called, “I Want to Kill You,” and it recounts her telling a previously stage III colon cancer patient, with whom she thought she had good rapport, that the disease had recurred. The patient’s immediate reaction in the heat of that moment was to say, Dr LoConte, I want to kill you. I want to blow your face off.
Already, there’s clearly tension when we are telling people what they don’t want to hear. I think the final piece of the puzzle goes back to the intrusion of the business of healthcare on the practice of medicine. This is what I witnessed very recently. One of the things that’s interesting to think about is how what we do is now framed as customer service. I know there’s deriding of this model, but if perception is reality, we have a system where patients are set up to view themselves as consumers.
Let’s say, for instance, you’re in the unfortunate circumstance of being diagnosed with cancer and your insurer gives you the option to go to multiple oncologists. If you’re online browsing for oncologists, how do you differentiate me from some of my colleagues? The answer on these rating websites often has to do with domains that are about the overall experience — not just the patient-doctor interaction but also things like wait time, friendliness of staff, and promptness of care delivery.
That, I think, is the final piece of the puzzle, because what I really risk when I sit down with a patient and lay out a treatment plan is overpromising and underdelivering. I am long used to citing median overall survival for expectation of outcome. Of course, every patient wants to be an exceptional responder. Most patients want to be on the latter half of median survival. No one wants to be on the disappointingly shorter half.
My point is that I’ve long been able to mitigate that uncertainty for patients. What is getting harder and harder to explain away is the delay incurred between someone’s diagnosis, my meeting them and laying out a treatment plan, and their actual initiation of that therapy.
This finally brings me to my recent personal encounter. I have long taken care of a patient, much like Dr LoConte’s, with an extremely calm demeanor. I thought we had a great therapeutic alliance. I had to tell the patient that the disease had recurred, and then I laid out a treatment plan. It took weeks and then months for the insurer to approve this plan despite my providing my note in a timely fashion with a mountain of evidence behind the regimen that I’d selected.
This is where I think insurers — when they deny, deflect, and delay — are not taking adequate responsibility for the impact that has on the therapeutic alliance between a patient and their doctor. These people are trusting us with their lives. As an oncologist, I’ve already told them something they didn’t want to hear, and now I’m compounding that with the uncertainty of when we can actually begin treatment.
This gentleman — who, again, is normally extremely kind and affable — showed up at my office and was incredibly hostile toward me and my staff because of the delay that he was encountering. We literally couldn’t tell him when his insurer was going to approve his treatment, which would have been financially disastrous if he had tried to pay for it himself out of pocket. He needed his insurer’s approval before we could start, but we didn’t know when he could start. That uncertainty and not knowing was gnawing away at him until he was at the end of his rope.
What I’m here to say is that this has been a difficult couple of years in healthcare. I’m well aware that our ER staff are on the front lines, as are our bedside and inpatient teams. Even in the outpatient setting, I think we’re seeing this crucible and we’re seeing the pressure just grow, and grow, and grow. It’s like fracking. The more you increase the pressure, the more eventually you’re going to find out where the cracks are.
These patients are the ultimate stakeholders. It’s their lives on the line, and we should be concerned, but perhaps ultimately not surprised, that they’re lashing out to be heard. Given no other resort, they are taking out their frustration and their aggression on us. It›s not fair, but I am newly aware of it because, in a patient with whom I thought we had a superb rapport, I saw that vanish. As soon as he thought that his life was at risk, his fight-or-flight response kicked in. I was not dealing with the same man I knew. I was dealing with someone who was desperate and who just wanted to know when he could get the treatment.
I think this has taken the likelihood of workplace hostility to a whole other level for those of us in healthcare.
For any patients listening, I beg of you, please don’t shoot the messenger. We are here to serve you the best we can, but there are many external factors at play. We are doing our best to mitigate those for you so we can deliver the care that we promised in as timely a fashion as we can.
I hope everyone out there can stay safe. Thank you.

Botanical Briefs: Neem Oil (Azadirachta indica)
Commonly known as neem or nimba, Azadirachta indica traditionally has been used as an oil or poultice to lighten skin pigment and reduce joint inflammation. Neem is a drought-resistant evergreen tree with thin serrated leaves, white fragrant flowers, and olivelike fruit (Figure 1). This plant is indigenous to India but also is readily found within tropical and semitropical environments throughout the Middle East, Southeast Asia, North Africa, and Australia.
Traditional Uses
For more than 4000 years, neem leaves, bark, fruit, and seeds have been used in food, insecticide, and herbal medicine cross-culturally in Indian Ayurvedic medicine and across Southeast Asia, particularly in Cambodia, Laos, Thailand, Myanmar, and Vietnam.1-3 Because of its many essential nutrients—oleic acid, palmitic acid, stearic acid, linoleic acid, behenic acid, arachidic acid, and palmitoleic acid—and readily available nature, some ethnic groups include neem in their diet.4 Neem commonly is used as a seasoning in soups and rice, eaten as a cooked vegetable, infused into teas and tonics, and pickled with other spices.5
All parts of the neem tree—both externally and internally—have been utilized in traditional medicine for the treatment of various diseases and ailments. The flowers have been used to treat eye diseases and dyspepsia, the fruit has been employed as an anthelmintic, the seeds and leaves have been used for malaria treatment and insecticide, the stem bark has been used for the treatment of diarrhea, and the root bark has been used for skin diseases and inflammation.6 Neem oil is a yellow-brown bitter substance that often is utilized to treat skin diseases such as psoriasis, eczema, fungal infections, and abscesses.
Case Report—A 77-year-old man presented with a diffuse rash across the lower back. He reported that he had been using topical neem oil to alleviate lower back pain and arthritis for the last 6 months with noted relief and improvement of back pain. After roughly 3 to 4 months of using neem oil, he noted a rash on the lower back, bilateral flanks, and buttocks (Figure 2). The rash was asymptomatic, and he denied any pruritus, scaling, pain, or burning. The patient was referred to dermatology and received a diagnosis of chemical leukoderma secondary to contact with A indica. The patient was advised to stop using the topical neem oil, and the rash was simply monitored, as it was asymptomatic.
Bioactivity
Research has elucidated multiple bioactivity mechanisms of neem, including melanogenesis-inhibitory activity, toxicity against pests, antimalarial activity, and antioxidant activity.1,7-9 Literature on the diverse phytochemical components of A indica indicate high levels of limonoids, flavonoids, and triterpenoids that are responsible for much of its antioxidant, anti-inflammatory, and insecticide properties.1,10
Melanogenesis-Inhibitory Activity—To date, neem has been added to a number of cosmetic products used in Ayurvedic medicine. One study of isolated compounds in A indica showed superior inhibitory activities against melanogenesis with minimal toxicity to cells (86.5%–105.1% cell viability). Western blot analysis of samples extracted and isolated from neem root and bark showed melanogenesis-inhibitory activities in B16 melanoma cells through the inhibition of microphthalmia-associated transcription factor expression and decreased expression of tyrosinase, as well as tyrosinase-related proteins 1 and 2, which are largely responsible for melanin synthesis.11 In another study, A indica flowers and their extracted constituents—6-deacetylnimbin and kaempferide—suggest melanogenesis-inhibitory activities in B16 melanoma cells with little to no toxicity to the cells (81.0%–111.7% cell viability).1 In an evaluationof A indica seed extracts, some of the isolated limonoids and diterpenoids exhibited a marked melanogenesis-inhibitory effect (74%–91% reduction of melanin content) with no toxicity to the cell.5 All of these studies indicate that active compounds in neem root, bark, flowers, and seeds may be potential skin-lightening agents.
Toxicity Against Pests—Neem seeds have phytochemicals that convey some insecticidal properties. The seeds often are ground into a powder, combined with water, and sprayed onto crops to act as an insecticide. As a natural method of nonpesticidal management, A indica acts as an antifeedant, insect repellent, and egg-laying deterrent that protects crops from damage. Studies of A indica have noted effective nonpesticidal management against arthropod pests such as armyworm, termites, and the oriental fruit fly.7,12,13
Antimalarial Activity—One study indicated that nimbolide, a limonoid from the neem plant, demonstrated antimalarial activity against Plasmodium falciparum. In separate cultures of asexual parasites and mature gametocytes, parasite numbers were less than 50% of the number in control cultures (8.0% vs 8.5% parasitemia, respectively).14 Thus, the lower parasite numbers indicated by this study highlight the antimalarial utility of nimbolide and neem oil.
Antioxidant and Anti-inflammatory Activity—Neem bark has been reported to have considerable antioxidant activity due to its high phenolic content.1,15 One study showed that azadirachtin and nimbolide in neem exhibited concentration-dependent antiradical scavenging activity and antioxidant properties.16
The anti-inflammatory potential for neem may occur via the inhibition of the nuclear factor-κB signaling pathway, which is linked to cancer, inflammation, and apoptosis.17 It also has been observed that nimbidin within neem extracts—such as leaves, bark, and seed extract—suppresses the function of macrophages and neutrophils relevant to inflammation.16 Another study indicated neem’s anti-inflammatory activity due to the regulation of proinflammatory enzymes such as cyclooxygenase and lipoxygenase.18
Safety, Toxicity, and Risks
Ingestion—Although neem is safe to use in the general population, neem oil poisoning has been reported, particularly in young children. Ingesting large quantities of neem has resulted in vomiting, hepatic toxicity, metabolic acidosis, late neurologic sequelae, and encephalopathy in young children.19 The diagnosis of neem oil poisoning is based on patient history, clinical examination, and imaging findings. Poisoning can manifest as drowsiness, tachypnea, and generalized seizures.20
Topical Application—Topical use of neem appears to be safe if the substance is diluted with other ingredients. However, direct application to the skin is not advised, as it may cause leukoderma and could induce allergic contact dermatitis and other allergic reactions.4
Final Thoughts
The use of neem extract for disease prevention and treatment has been prevalent around the world since ancient times. Neem has been documented to possess melanogenesis-inhibitory activity, toxicity against pests, antimalarial activity, and antioxidant activity by means of tyrosinase inhibition, phytochemical production, limonoid expression, and nuclear factor-κB regulation, respectively. However, topical use of neem may trigger a cutaneous response, highlighting the importance of considering a diagnosis of neem oil–induced chemical leukoderma when patients present with a hypopigmented rash and relevant history.

Practice Points
- Neem is a traditional herb with various bioactivities, such as melanogenesis-inhibitory activity, toxicity against pests, antimalarial activity, and antioxidant activity.
- Neem should be used with caution as a remedy because of its skin-lightening properties, which are attributed to melanogenesis-inhibitory activity via tyrosinase inhibition.
- Chemical leukoderma should be included in the differential diagnosis when a patient presents with a hypopigmented rash after topical use of neem products.
