Abortion debate may affect Rx decisions for pregnant women
Obstetrician Beverly Gray, MD, is already seeing the effects of the Roe v. Wade abortion debate in her North Carolina practice.
The state allows abortion but requires that women get counseling with a qualified health professional 72 hours before the procedure. “Aside from that, we still have patients asking for more efficacious contraceptive methods just in case,” said Dr. Gray, residency director and division director for women’s community and population health and associate professor for obstetrics and gynecology at Duke University, Durham, N.C.
Patients and staff in her clinic have also been approaching her about tubal ligation. “They’re asking about additional birth control methods because they’re concerned about what’s going to happen” with the challenge to the historic Roe v. Wade decision in the Supreme Court and subsequent actions in the states to restrict or ban abortion, she said.
This has implications not just for abortion but for medications known to affect pregnancy. “What I’m really worried about is physicians will be withholding medicine because they’re concerned about teratogenic effects,” said Dr. Gray.
With more states issuing restrictions on abortion, doctors are worried that patients needing certain drugs to maintain their lupus flares, cancer, or other diseases may decide not to take them in the event they accidentally become pregnant. If the drug is known to affect the fetus, the fear is a patient who lives in a state with abortion restrictions will no longer have the option to terminate a pregnancy.
Instead, a scenario may arise in which the patient – and their physician – may opt not to treat at all with an otherwise lifesaving medication, experts told this news organization.
The U.S. landscape on abortion restrictions
A leaked draft of a U.S. Supreme Court opinion on Mississippi’s 15-week abortion ban has sent the medical community into a tailspin. The case, Dobbs v. Jackson Women’s Health Organization, challenges the 1973 Roe v. Wade decision that affirms the constitutional right to abortion. It’s anticipated the high court will decide on the case in June.
Although the upcoming decision is subject to change, the draft indicated the high court would uphold the Mississippi ban. This would essentially overturn the 1973 ruling. An earlier Supreme Court decision allowing a Texas law banning abortion at 6 weeks suggests the court may already be heading in this direction. At the state level, legislatures have been moving on divergent paths – some taking steps to preserve abortion rights, others initiating restrictions.
More than 100 abortion restrictions in 19 states took effect in 2021, according to the Guttmacher Institute, which tracks such metrics. In 2022, “two key themes are anti-abortion policymakers’ continued pursuit of various types of abortion bans and restrictions on medication abortion,” the institute reported.
Forty-six states and the District of Columbia have introduced 2,025 restrictions or proactive measures on sexual and reproductive health and rights so far this year. The latest tally from Guttmacher, updated in late May, revealed that 11 states so far have enacted 42 abortion restrictions. A total of 6 states (Arizona, Florida, Idaho, Kentucky, Oklahoma, and Wyoming) have issued nine bans on abortion.
Comparatively, 11 states have enacted 19 protective abortion measures.
Twenty-two states have introduced 117 restrictions on medication abortions, which account for 54% of U.S. abortions. This includes seven measures that would ban medication abortion outright, according to Guttmacher. Kentucky and South Dakota collectively have enacted 14 restrictions on medication abortion, as well as provisions that ban mailing of abortion pills.
Chilling effect on prescribing
Some physicians anticipate that drugs such as the “morning-after” pill (levonorgestrel) will become less available as restrictions go into effect, since these are medications designed to prevent pregnancy.*
However, the ongoing effort to put a lid on abortion measures has prompted concerns about a trickle-down effect on other medications that are otherwise life-changing or lifesaving to patients but pose a risk to the fetus.
Several drugs are well documented to affect fetal growth and development of the fetus, ranging from mild, transitory effects to severe, permanent birth defects, said Ronald G. Grifka, MD, chief medical officer of University of Michigan Health-West and clinical professor of pediatrics at the University of Michigan Medical School, Ann Arbor. “As new medications are developed, we will need heightened attention to make sure they are safe for the fetus,” he added.
Certain teratogenic medications are associated with a high risk of abortion even though this isn’t their primary use, noted Christina Chambers, PhD, MPH, co-director of the Center for Better Beginnings and associate director with the Altman Clinical & Translational Research Institute at the University of California, San Diego.
“I don’t think anyone would intentionally take these drugs to induce spontaneous abortion. But if the drugs pose a risk for it, I can see how the laws might be stretched” to include them, said Dr. Chambers.
Methotrexate, a medication for autoimmune disorders, has a high risk of spontaneous abortion. So do acne medications such as isotretinoin.
Patients are usually told they’re not supposed to get pregnant on these drugs because there’s a high risk of pregnancy loss and risk of malformations and potential learning problems in the fetus. But many pregnancies aren’t planned, said Dr. Chambers. “Patients may forget about the side effects or think their birth control will protect them. And the next time they refill the medication, they may not hear about the warnings again.”
With a restrictive abortion law or ban in effect, a woman might think: “I won’t take this drug because if there’s any potential that I might get pregnant, I won’t have the option to abort an at-risk pregnancy.” Women and their doctors, for that matter, don’t want to put themselves in this position, said Dr. Chambers.
Rheumatologist Megan Clowse, MD, who prescribes several medications that potentially cause major birth defects and pregnancy loss, worries about the ramifications of these accumulating bans.
“Methotrexate has been a leading drug for us for decades for rheumatoid arthritis. Mycophenolate is a vital drug for lupus,” said Dr. Clowse, associate professor of medicine at Duke University’s division of rheumatology and immunology.
Both methotrexate and mycophenolate pose about a 40% risk of pregnancy loss and significantly increase the risk for birth defects. “I’m definitely concerned that there might be doctors or women who elect not to use those medications in women of reproductive age because of the potential risk for pregnancy and absence of abortion rights,” said Dr. Clowse.
These situations might force women to use contraceptives they don’t want to use, such as hormonal implants or intrauterine devices, she added. Another side effect is that women and their partners may decide to abstain from sex.
The iPLEDGE factor
Some rheumatology drugs like lenalidomide (Revlimid) require a valid negative pregnancy test in a lab every month. Similarly, the iPLEDGE Risk Evaluation and Mitigation Strategy seeks to reduce the teratogenicity of isotretinoin by requiring two types of birth control and regular pregnancy tests by users.
For isotretinoin specifically, abortion restrictions “could lead to increased adherence to pregnancy prevention measures which are already stringent in iPLEDGE. But on the other hand, it could lead to reduced willingness of physicians to prescribe or patients to take the medication,” said Dr. Chambers.
With programs like iPLEDGE in effect, the rate of pregnancies and abortions that occur in dermatology are relatively low, said Jenny Murase, MD, associate clinical professor of dermatology at the University of California, San Francisco.
Nevertheless, as a physician who regularly prescribes medications like isotretinoin in women of childbearing age, “it’s terrifying to me that a woman wouldn’t have the option to terminate the pregnancy if a teratogenic effect from the medication caused a severe birth defect,” said Dr. Murase.
Dermatologists use other teratogenic medications such as thalidomide, mycophenolate mofetil, and methotrexate for chronic dermatologic disease like psoriasis and atopic dermatitis.
The situation is especially tricky for dermatologists since most patients – about 80% – never discuss their pregnancy with their specialist prior to pregnancy initiation. Dr. Murase recalls when a patient with chronic plaque psoriasis on methotrexate in her late 40s became pregnant and had an abortion even before Dr. Murase became aware of the pregnancy.
Because dermatologists routinely prescribe long-term medications for chronic diseases like acne, psoriasis, and atopic dermatitis, it is important to have a conversation regarding the risks and benefits of long-term medication should a pregnancy occur in any woman of childbearing age, she said.
Fewer women in clinical trials?
Abortion restrictions could possibly discourage women of reproductive age to participate in a clinical trial for a new medication, said Dr. Chambers.
A female patient with a chronic disease who’s randomized to receive a new medication may be required to use certain types of birth control because of unknown potential adverse effects the drug may have on the fetus. But in some cases, accidental pregnancies happen.
The participant in the trial may say, “I don’t know enough about the safety of this drug in pregnancy, and I’ve already taken it. I want to terminate the pregnancy,” said Dr. Chambers. Thinking ahead, a woman may decide not to do the trial to avoid the risk of getting pregnant and not having the option to terminate the pregnancy.
This could apply to new drugs such as antiviral treatments, or medications for severe chronic disease that typically have no clinical trial data in pregnancy prior to initial release into the market.
Women may start taking the drug without thinking about getting pregnant, then realize there are no safety data and become concerned about its effects on a future pregnancy.
The question is: Will abortion restrictions have a chilling effect on these new drugs as well? Patients and their doctors may decide not to try it until more data are available. “I can see where abortion restrictions would change the risk or benefit calculation in thinking about what you do or don’t prescribe or take during reproductive age,” said Dr. Chambers.
The upside of restrictions?
If there’s a positive side to these developments with abortion bans, it may encourage women taking new medications or joining clinical trials to think even more carefully about adherence to effective contraception, said Dr. Chambers.
Some methods are more effective than others, she emphasized. “When you have an unplanned pregnancy, it could mean that the method you used wasn’t optimal or you weren’t using it as recommended.” A goal moving forward is to encourage more thoughtful use of highly effective contraceptives, thus reducing the number of unplanned pregnancies, she added.
If patients are taking methotrexate, “the time to think about pregnancy is before getting pregnant so you can switch to a drug that’s compatible with pregnancy,” she said.
This whole thought process regarding pregnancy planning could work toward useful health goals, said Dr. Chambers. “Nobody thinks termination is the preferred method, but planning ahead should involve a discussion of what works best for the patient.”
Patients do have other choices, said Dr. Grifka. “Fortunately, there are many commonly prescribed medications which cross the placenta and have no ill effects on the fetus.”
Talking to patients about choices
Dr. Clowse, who spends a lot of time training rheumatologists, encourages them to have conversations with patients about pregnancy planning. It’s a lot to manage, getting the right drug to a female patient with chronic illness, especially in this current climate of abortion upheaval, she noted.
Her approach is to have an open and honest conversation with patients about their concerns and fears, what the realities are, and what the potential future options are for certain rheumatology drugs in the United States.
Some women who see what’s happening across the country may become so risk averse that they may choose to die rather than take a lifesaving drug that poses certain risks under new restrictions.
“I think that’s tragic,” said Dr. Clowse.
To help their patients, Dr. Gray believes physicians across specialties should better educate themselves about physiology in pregnancy and how to counsel patients on the impact of not taking medications in pregnancy.
In her view, it’s almost coercive to say to a patient, “You really need to have effective contraception if I’m going to give you this lifesaving or quality-of-life-improving medication.”
When confronting such scenarios, Dr. Gray doesn’t think physicians need to change how they counsel patients about contraception. “I don’t think we should be putting pressure on patients to consider other permanent methods just because there’s a lack of abortion options.”
Patients will eventually make those decisions for themselves, she said. “They’re going to want a more efficacious method because they’re worried about not having access to abortion if they get pregnant.”
Dr. Gray reports being a site principal investigator for a phase 3 trial for VeraCept IUD, funded by Sebela Pharmaceuticals. Dr. Clowse reports receiving research funding and doing consulting for GlaxoSmithKline.

Some methods are more effective than others, she emphasized. “When you have an unplanned pregnancy, it could mean that the method you used wasn’t optimal or you weren’t using it as recommended.” A goal moving forward is to encourage more thoughtful use of highly effective contraceptives, thus reducing the number of unplanned pregnancies, she added.
If patients are taking methotrexate, “the time to think about pregnancy is before getting pregnant so you can switch to a drug that’s compatible with pregnancy,” she said.
This whole thought process regarding pregnancy planning could work toward useful health goals, said Dr. Chambers. “Nobody thinks termination is the preferred method, but planning ahead should involve a discussion of what works best for the patient.”
Patients do have other choices, said Dr. Grifka. “Fortunately, there are many commonly prescribed medications which cross the placenta and have no ill effects on the fetus.”
Talking to patients about choices
Dr. Clowse, who spends a lot of time training rheumatologists, encourages them to have conversations with patients about pregnancy planning. It’s a lot to manage, getting the right drug to a female patient with chronic illness, especially in this current climate of abortion upheaval, she noted.
Her approach is to have an open and honest conversation with patients about their concerns and fears, what the realities are, and what the potential future options are for certain rheumatology drugs in the United States.
Some women who see what’s happening across the country may become so risk averse that they may choose to die rather than take a lifesaving drug that poses certain risks under new restrictions.
“I think that’s tragic,” said Dr. Clowse.
To help their patients, Dr. Gray believes physicians across specialties should better educate themselves about physiology in pregnancy and how to counsel patients on the impact of not taking medications in pregnancy.
In her view, it’s almost coercive to say to a patient, “You really need to have effective contraception if I’m going to give you this lifesaving or quality-of-life-improving medication.”
When confronting such scenarios, Dr. Gray doesn’t think physicians need to change how they counsel patients about contraception. “I don’t think we should be putting pressure on patients to consider other permanent methods just because there’s a lack of abortion options.”
Patients will eventually make those decisions for themselves, she said. “They’re going to want a more efficacious method because they’re worried about not having access to abortion if they get pregnant.”
Dr. Gray reports being a site principal investigator for a phase 3 trial for VeraCept IUD, funded by Sebela Pharmaceuticals. Dr. Clowse reports receiving research funding and doing consulting for GlaxoSmithKline.

Updated AHA/ASA guideline changes care for spontaneous intracerebral hemorrhage
Many strategies widely considered “standard care” for managing spontaneous intracerebral hemorrhage (ICH) are not as effective as previously thought and are no longer recommended in updated guidelines from the American Heart Association/American Stroke Association (ASA).
Compression stockings, antiseizure medication, and steroid treatment are among the treatments with uncertain effectiveness, the writing group says.
The 2022 Guideline for the Management of Patients With Spontaneous ICH was published online in Stroke. The 80-page document contains major changes and refinements to the 2015 guideline on ICH management.
“Advances have been made in an array of fields related to ICH, including the organization of regional health care systems, reversal of the negative effects of blood thinners, minimally invasive surgical procedures, and the underlying disease in small blood vessels,” Steven M. Greenberg, MD, PhD, chair of the guideline writing group with Harvard Medical School and Massachusetts General Hospital, both in Boston, said in a news release.
“We’ve updated sections across the board. There’s probably no area that went untouched with some tweaking and new evidence added that led to some changes in level of evidence or strength of a recommendation,” Dr. Greenberg added in an interview with this news organization.
“Each section comes with knowledge gaps, and it wasn’t hard to come up with knowledge gaps in every section,” Dr. Greenberg acknowledged.
Time-honored treatments no more?
Among the key updates are changes to some “time-honored” treatments that continue to be used with some “regularity” for patients with ICH, yet appear to confer either no benefit or harm, Dr. Greenberg said.
For example, for emergency or critical care treatment of ICH, prophylactic corticosteroids or continuous hyperosmolar therapy is not recommended, because it appears to have no benefit for outcome, while use of platelet transfusions outside the setting of emergency surgery or severe thrombocytopenia appears to worsen outcome, the authors say.
Use of graduated knee- or thigh-high compression stockings alone is not an effective prophylactic therapy for prevention of deep vein thrombosis (DVT). Instead, intermittent pneumatic compression (IPC) starting on the day of diagnosis is now recommended for DVT prophylaxis.
“This is an area where we still have a lot of exploration to do. It is unclear whether even specialized compression devices reduce the risks of deep vein thrombosis or improve the overall health of people with a brain bleed,” Dr. Greenberg said in the release.
The new guidance advises against use of antiseizure or antidepressant medications for ICH patients in whom there is no evidence of seizures or depression.
In clinical trials, antiseizure medication did not contribute to improvements in functionality or long-term seizure control, and the use of antidepressants increased the chance of bone fractures, the authors say.
The guideline also provides updated recommendations for acute reversal of anticoagulation after ICH. It highlights the use of protein complex concentrate for reversal of vitamin K antagonists, such as warfarin; idarucizumab for reversal of the thrombin inhibitor dabigatran; and andexanet alfa for reversal of factor Xa inhibitors, such as rivaroxaban, apixaban, and edoxaban.
For acute blood pressure lowering after mild to moderate ICH, treatment regimens that limit blood pressure variability and achieve smooth, sustained blood pressure control appear to reduce hematoma expansion and yield better functional outcome, the guideline says.
It also notes that minimally invasive approaches for hematoma evacuation, compared with medical management alone‚ have been shown to reduce mortality.
For patients with cerebellar hemorrhage, indications for immediate surgical evacuation with or without an external ventricular drain to reduce mortality now include larger volume (> 15 mL) in addition to previously recommended indications of neurologic deterioration, brainstem compression, and hydrocephalus, the authors note.
However, a “major knowledge gap is whether we can improve functional outcome with hematoma evacuation,” Dr. Greenberg said.
Multidisciplinary care
For rehabilitation after ICH, the guideline reinforces the importance of having a multidisciplinary team to develop a comprehensive plan for recovery.
Starting rehabilitation activities such as stretching and functional task training may be considered 24 to 48 hours following mild or moderate ICH. However, early aggressive mobilization within the first 24 hours has been linked to an increased risk of death within 14 days after an ICH, the guideline says.
Knowledge gaps include how soon it’s safe to return to work, drive, and participate in other social engagements. Recommendations on sexual activity and exercise levels that are safe after a stroke are also needed.
“People need additional help with these lifestyle changes, whether it’s moving around more, curbing their alcohol use, or eating healthier foods. This all happens after they leave the hospital, and we need to be sure we are empowering families with the information they may need to be properly supportive,” Dr. Greenberg says in the release.
The guideline points to the patient’s home caregiver as a “key and sometimes overlooked” member of the care team. It recommends psychosocial education, practical support, and training for the caregiver to improve the patient’s balance, activity level, and overall quality of life.
Opportunity for prevention?
The guideline also suggests there may be an opportunity to prevent ICH in some people through neuroimaging markers.
While neuroimaging is not routinely performed as a part of risk stratification for primary ICH risk, damage to small blood vessels that is associated with ICH may be evident on MRI that could signal future ICH risk, the guideline says.
“We added to the guidelines for the first time a section on mostly imaging markers of risk for having a first-ever hemorrhage,” Dr. Greenberg said in an interview.
“We don’t make any recommendations as to how to act on these markers because there is a knowledge gap. The hope is that we’ll see growth in our ability to predict first-ever hemorrhage and be able to do things to prevent first-ever hemorrhage,” he said.
“We believe the wide range of knowledge set forth in the new guideline will translate into meaningful improvements in ICH care,” Dr. Greenberg adds in the release.
The updated guideline has been endorsed by the American Association of Neurological Surgeons and Congress of Neurological Surgeons, the Society of Vascular and Interventional Neurology, and the Neurocritical Care Society. The American Academy of Neurology has affirmed the value of this statement as an educational tool for neurologists.
This research had no commercial funding. Dr. Greenberg has disclosed no relevant financial relationships. A complete list of disclosures for the guideline group is available with the original article.

Air pollution is a seizure trigger for patients with epilepsy
, a unique new study suggests.
The link between daily outdoor CO exposure and seizure risk was particularly evident for subclinical seizures – those in patients with abnormal electroencephalography (EEG) signals but no clinical symptoms.
“Our findings suggest that people with epilepsy should avoid high CO exposure to reduce potential seizure risk,” said study investigator Zhuying Chen, PhD candidate, department of biomedical engineering, University of Melbourne.
The study was published online in Epilepsia.
Pollution’s impact on brain health
Emerging evidence indicates air pollution affects brain health and may increase the risk of hospitalization or outpatient visits for epilepsy. However, little is known about the effect of pollution on the occurrence of epileptic seizures.
The study used two independent long-term seizure datasets – the NeuroVista (NV) study and the Seer App seizure diary (SD). In the NeuroVista study, researchers recorded continuous intracranial iEEG from patients with refractory focal epilepsy who had been implanted with a personal seizure advisory device that wirelessly recorded seizures on an external device.
The SD dataset included diaries documenting self-reported seizures, seizure cycles, and medication adherence.
Researchers collected data on hourly concentrations of outdoor CO, nitrogen dioxide (NO2), particulate matter of 10 μm or less in diameter (PM10), ozone (O3), and sulfur dioxide (SO2). The levels were measured at air quality monitoring stations in Australia.
Investigators aggregated hourly observations into daily mean data. All daily concentrations of CO and SO2 and at least 95% of daily concentrations of NO2, O3, and PM10 were within Australian air quality standards, said Mr. Chen.
The study included 49 participants, with epilepsy data on 15 patients in the NeuroVista study and on 34 from the SD dataset.
Overall, 6,692 epileptic seizures on 3,639 seizure days were recorded during 23,349 follow-up days from 2010 to 2012 (NV dataset) and 2018 to 2021 (SD dataset).
The investigators found a significant positive association between CO concentrations and epileptic seizure risks. The relative risk (RR) was 1.04 (95% confidence interval, 1.01–1.07; P < .01) for an interquartile range (IQR) increase of CO (0.13 parts per million).
Sex differences
There were no significant relationships for the other four air pollutants. However, Mr. Chen noted that Australia has very low air pollution levels; most usually are within World Health Organization air quality guidelines.
“Our findings may not be generalized to other countries with high air pollution levels,” said Mr. Chen. He noted that the relatively small number of patients in the study may limit the statistical power to detect some associations.
The study showed that females had a significantly increased risk of epileptic seizures when exposed to elevated CO (RR, 1.05; 95% CI, 1.01–1.08; P < .05) and NO2 (RR, 1.09; 95% CI, 1.01–1.16; P < .05) concentrations. There were no significant associations in males for any air pollutants.
Differences in outdoor activities and behaviors such as smoking and exercise may lead to variations in environmental exposure and help explain the sex differences, said Mr. Chen. These differences may also be due to the study’s limited sample size.
Analyzing the two datasets separately, the researchers found there was a significant association between CO concentration and epileptic seizure risk in the NV dataset (RR, 1.10; 95% CI, 1.03–1.17; P < .01).
There were no significant associations in the SD dataset for any air pollutants. This may be because only clinical seizures – those associated with evident symptoms – are self-reported, said Mr. Chen. He also noted that seizure diaries may be unreliable.
In the NV dataset, the epileptic seizure risk was significantly increased when only subclinical seizures were considered (RR, 1.20; 95% CI, 1.12–1.28; P < .001) for an IQR increase of CO concentration.
The risk was significantly decreased by 13% for subclinical seizures with an IQR increase of PM10 and by 9% for subclinical seizures with an IQR increase of SO2 concentrations.
These negative associations should be interpreted with caution, inasmuch as the associations were not robust in subsequent subgroup and sensitivity analyses, said Mr. Chen.
There were no significant associations when considering clinical seizures for any air pollutants.
The positive association for subclinical but not clinical seizures suggests that low-level CO exposure may not be strong enough to directly trigger clinical seizures, said Mr. Chen.
Although previous research has demonstrated adverse neurologic effects of exposure to air pollutants, most studies were based on hospital databases or registers. Thus, they may have missed seizures that did not lead to hospital admission.
Unclear mechanism
The exact mechanisms linking air pollution to seizures are unclear but probably involve the synergistic interaction of multiple pathways, said Mr. Chen. “Air pollution may affect brain metabolism, alter the immune response of the brain, and induce oxidative stress and neuroinflammation, causing the brain to be more susceptible to seizures,” he noted.
This is the first study to investigate seizure rates through intracranial EEG signals and self-reported seizure diaries. It’s also the first to look into the impact of pollutants at low concentration levels on subclinical seizures.
However, the study has some limitations. Self-reported seizures in the SD dataset might underestimate the influence of air pollution on seizures. The study used postal codes as proxies for exposure to pollution, which could introduce measurement errors and underestimate associations.
In addition, Mr. Chen noted that seizures from the NeuroVista dataset were recorded from patients with drug-resistant focal epilepsy. “Whether our findings can be generalized to other epilepsy types needs further investigation.”
The study could have important clinical and public health implications. For example, said Mr. Chen, it’s possible that seizure risk could be reduced through behavioral interventions, such as avoiding being outside or using an air filtration system when pollutant levels are high.
“Clinicians could counsel their patients to avoid the potential risk of high carbon monoxide exposure,” he said.
CO exposure could be a new factor for seizure risk forecasting, which could reduce the uncertainty of seizures and help guide epilepsy management, Mr. Chen added.
The study was supported by the Melbourne Monash Consciousness Research Seed Funding and an Australian National Health and Medical Research Council Ideas grant. Mr. Chen has disclosed no relevant financial relationships.

Investigators aggregated hourly observations into daily mean data. All daily concentrations of CO and SO2 and at least 95% of daily concentrations of NO2, O3, and PM10 were within Australian air quality standards, said Mr. Chen.
The study included 49 participants, with epilepsy data on 15 patients in the NeuroVista study and on 34 from the SD dataset.
Overall, 6,692 epileptic seizures on 3,639 seizure days were recorded during 23,349 follow-up days from 2010 to 2012 (NV dataset) and 2018 to 2021 (SD dataset).
The investigators found a significant positive association between CO concentrations and epileptic seizure risks. The relative risk (RR) was 1.04 (95% confidence interval, 1.01–1.07; P < .01) for an interquartile range (IQR) increase of CO (0.13 parts per million).
Sex differences
There were no significant relationships for the other four air pollutants. However, Mr. Chen noted that Australia has very low air pollution levels; most usually are within World Health Organization air quality guidelines.
“Our findings may not be generalized to other countries with high air pollution levels,” said Mr. Chen. He noted that the relatively small number of patients in the study may limit the statistical power to detect some associations.
The study showed that females had a significantly increased risk of epileptic seizures when exposed to elevated CO (RR, 1.05; 95% CI, 1.01–1.08; P < .05) and NO2 (RR, 1.09; 95% CI, 1.01–1.16; P < .05) concentrations. There were no significant associations in males for any air pollutants.
Differences in outdoor activities and behaviors such as smoking and exercise may lead to variations in environmental exposure and help explain the sex differences, said Mr. Chen. These differences may also be due to the study’s limited sample size.
Analyzing the two datasets separately, the researchers found there was a significant association between CO concentration and epileptic seizure risk in the NV dataset (RR, 1.10; 95% CI, 1.03–1.17; P < .01).
There were no significant associations in the SD dataset for any air pollutants. This may be because only clinical seizures – those associated with evident symptoms – are self-reported, said Mr. Chen. He also noted that seizure diaries may be unreliable.
In the NV dataset, the epileptic seizure risk was significantly increased when only subclinical seizures were considered (RR, 1.20; 95% CI, 1.12–1.28; P < .001) for an IQR increase of CO concentration.
The risk was significantly decreased by 13% for subclinical seizures with an IQR increase of PM10 and by 9% for subclinical seizures with an IQR increase of SO2 concentrations.
These negative associations should be interpreted with caution, inasmuch as the associations were not robust in subsequent subgroup and sensitivity analyses, said Mr. Chen.
There were no significant associations when considering clinical seizures for any air pollutants.
The positive association for subclinical but not clinical seizures suggests that low-level CO exposure may not be strong enough to directly trigger clinical seizures, said Mr. Chen.
Although previous research has demonstrated adverse neurologic effects of exposure to air pollutants, most studies were based on hospital databases or registers. Thus, they may have missed seizures that did not lead to hospital admission.
Unclear mechanism
The exact mechanisms linking air pollution to seizures are unclear but probably involve the synergistic interaction of multiple pathways, said Mr. Chen. “Air pollution may affect brain metabolism, alter the immune response of the brain, and induce oxidative stress and neuroinflammation, causing the brain to be more susceptible to seizures,” he noted.
This is the first study to investigate seizure rates through intracranial EEG signals and self-reported seizure diaries. It’s also the first to look into the impact of pollutants at low concentration levels on subclinical seizures.
However, the study has some limitations. Self-reported seizures in the SD dataset might underestimate the influence of air pollution on seizures. The study used postal codes as proxies for exposure to pollution, which could introduce measurement errors and underestimate associations.
In addition, Mr. Chen noted that seizures from the NeuroVista dataset were recorded from patients with drug-resistant focal epilepsy. “Whether our findings can be generalized to other epilepsy types needs further investigation.”
The study could have important clinical and public health implications. For example, said Mr. Chen, it’s possible that seizure risk could be reduced through behavioral interventions, such as avoiding being outside or using an air filtration system when pollutant levels are high.
“Clinicians could counsel their patients to avoid the potential risk of high carbon monoxide exposure,” he said.
CO exposure could be a new factor for seizure risk forecasting, which could reduce the uncertainty of seizures and help guide epilepsy management, Mr. Chen added.
The study was supported by the Melbourne Monash Consciousness Research Seed Funding and an Australian National Health and Medical Research Council Ideas grant. Mr. Chen has disclosed no relevant financial relationships.

Smartphone diagnosis in infant seizures could be highly effective
This video transcript has been edited for clarity.
Andrew N. Wilner, MD: Welcome to Medscape. I’m Dr Andrew Wilner, reporting from the American Epilepsy Society meeting.
Today, I have the pleasure of speaking with Dr. Chethan Rao, a child and adolescent neurology resident from the Mayo Clinic in Jacksonville, Fla. Dr. Rao has a particular interest in pediatric epilepsy. Welcome, Dr. Rao.
Chethan Rao, DO: Thank you, Dr. Wilner. It’s a pleasure to be here, and thanks for taking the time to highlight our work.
Dr. Wilner: You had a very interesting paper at the meeting that I wanted to talk about, focused on infantile spasms and smartphone video. Before we dive into the paper, tell us: What are infantile spasms, and why is it important to diagnose them early?
Dr. Rao: Infantile spasms, also known as epileptic spasms, are 1- to 2-second seizures, and they typically consist of sudden stiffening of the body with brief bending forward or backward of the arms, legs, and head. They usually happen around age 3-8 months, and they typically occur in clusters, most often after awakening from sleep.
The incidence is about 1 in 2,000-3,000 children. Many kids with spasms go on to develop seizures that are very difficult to treat, like Lennox-Gastaut epilepsy, and many go on to have developmental delays as well.
Dr. Wilner: Are these subtle? In other words, could a parent have a child like that and not really recognize that this is something abnormal? Or are they so dramatic that parents say: “We’re going to the emergency room?”
Dr. Rao: One of the problems that we encounter often is that in this age group of infants, they have benign sleep myoclonus; they have Sandifer syndrome related to reflux. Those can be very difficult mimics of spasms. They’re not the most clear-cut, but they look usually different enough from normal baby movements that they get parents to seek medical attention.
Dr. Wilner: You mentioned that the infantile spasms really are a type of epilepsy and symptomatic, usually, of some underlying neurologic condition. Why is it so important to diagnose them early?
Dr. Rao: Great question. Many studies have looked at developmental outcomes based on when spasms were diagnosed and treated, and all of them have replicated time over time that the earlier you get to treatment for the spasms, the better the outcomes are for seizure control and for development.
For this reason, infantile spasm is considered a neurologic urgency in our world. Like I said, accurate diagnosis is often complicated by these potential mimics. Prompt EEG is one of the most important things for confirmation of diagnosis.
Dr. Wilner: But to get that EEG, it has to get all the way to the neurologist, right? It’s not something they’re going to do in the ER. I saw a statistic: There are millions, if not billions, of smartphones out there. Where does the smartphone come in?
Dr. Rao: Absolutely. One of the things that we have on our side these days is that almost everyone has a smartphone at their disposal. One of the recent polls in 2021 showed that more than 95% of adults of childbearing age have smartphones with video access. As some other studies have shown in the adult world, we all really have an epilepsy monitoring unit minus the EEG in our own pockets.
It’s definitely a useful tool, as that first screening video can be used in adjunct to history and physical. There have been many of studies on the adult epilepsy side showing the predictive value of smartphone video for differentiating things like epileptic seizures and nonepileptic spells. What we wanted to do is use smartphone video to pin the diagnosis early of infantile spasms and get it treated as quickly as possible.
Dr. Wilner: I’m a fan. Every now and then, I do have a patient who brings in a video of some spell. I’m an adult neurologist. The patient had a spell, and you ask them – of course they don’t remember – and you ask the witness, who usually is not a trained observer. There have been one or two occasions where I thought: “Well, I don’t know if that was really a seizure.” Then they show me the video and it’s like, “Wow, that is definitely a convulsion.” A picture definitely can be worth a thousand words.
You studied this systematically for your poster. Tell me about what you did.
Dr. Rao: Since the poster, we’ve actually expanded the study, so I’ll give you the updated version. We looked at 101 infants retrospectively at two large children’s health care centers: Nemours Children’s, associated with Mayo Clinic in Jacksonville, Fla., and Texas Children’s Hospital in Houston. We narrowed it down to 80 patients whom we included. Of these, 43 had smartphone video capture when they first presented and 37 had no video when they first presented.
We found a 17-day difference by median in the time to diagnosis and treatment. In other words, the video group was diagnosed and treated 17 days by median, compared with the no-video group. Although 17 days may not sound like a big number, in this context it can make a huge difference. That’s been shown by one of these key studies in our field called the UK Infantile Spasms Study. The 2-week difference made about a 10-point difference on the developmental scale that they use – so pretty significant.
Dr. Wilner: Let me think about this for a minute. Was that because the parents brought the child in with their video and the doctor said, “Hey, that’s infantile spasms. Here’s your shot of ACTH [or whatever they’re using these days].” Or was it because the parents who were attentive enough to use video brought their kids in sooner?
Or was this the time from when they brought the child in to treatment? Is that the time you looked at? So it wasn’t just that these were more attentive parents and more likely to use the video – you’re looking at the time from presentation with or without video until treatment, is that right?
Dr. Rao: We looked to the time from the start of the spasms, as reported by the parents, to the time of diagnosis and then the start of spasms to the time of treatment. What you asked was a fantastic question. We wanted to know who these parents are who are taking videos versus the ones that are not.
We looked at the race/ethnicity data and socioeconomic status data. There were no significant differences between the video and nonvideo group. That would not explain the difference in our results here.
Dr. Wilner: Do you have plans to follow these approximately 40 children 5 years from now and see who’s riding a bicycle and who’s still stuck in the stroller? Is there going to be a difference?
Dr. Rao: Because time to diagnosis and time to treatment were our primary outcomes, long-term follow-up may not really help as much in this study. We did have a couple of other ideas for future studies. One that we wanted to look at was kids who have risk factors for developing spasms, such as trisomy 21, tuberous sclerosis, and congenital cortical malformations; those kids are at a much higher risk for developing spasms around 3-8 months of life.
In giving targeted counseling to those families about how they can use smartphone video to minimize the time to diagnosis and treatment, we think we may be able to learn more and maybe do that prospectively.
The other interesting idea is using artificial intelligence technology for spasm detection in some of these smartphone videos. They’re already using it for different seizure types. It could be an efficient first pass when we get a whole bunch of smartphone videos to determine which ones we need to pursue further steps – to see whether we need to get long-term EEG monitoring or not.
Dr. Wilner: As an epileptologist, I was going to say that we have smartphone EKG. All we need now is smartphone EEG, and then you’ll have all the information you need on day one. It may be a ways away.
As a bottom line, would it be fair to say that parents should not hesitate to take a video of any suspiciously abnormal behavior and bring it to their family doctor or pediatric neurologist?
Dr. Rao: Yes. I was happy to see the Tuberous Sclerosis Alliance put out a promotional video that had some steps for when parents see things that are suspicious for spasms, and they do recommend using smartphone video and promptly showing it to their doctors. I think the difference that we hope to provide in this study is that we can now quantify the effect of having that smartphone video when they first present.
My takeaway from this study that I would like to show is encouraging the use of smartphone video as an adjunct tool and for providers to ask for the videos, but also for these pediatric centers to develop an infrastructure – either a secure, monitored email address like we have at our center or a patient portal – where parents can submit video concerning for spasms.
Dr. Wilner: Save the trip to the doctor. Get that video out there first.
Dr. Rao: Especially in the pandemic world, right?
Dr. Wilner: Yes. I understand that you are a neurology resident. To wrap up, what’s the next step for you?
Dr. Rao: I’m finishing up my child neurology residency this year, and I’m moving out to Stanford for pediatric epilepsy fellowship. We’re preparing this project we’re talking about for submission soon, and we’re working on another project, which is a systematic review of genetic testing and the presurgical workup for pediatric drug-resistant focal epilepsy.
Dr. Wilner: Excellent. That’s pretty exciting. Good luck to you. I want to thank you very much for telling us about your research.
Dr. Rao: It was a pleasure speaking with you, and I look forward to the next time.
Dr. Wilner: I’m Dr Andrew Wilner, reporting for Medscape. Thanks for watching.

Contraception for women taking enzyme-inducing antiepileptics
Topiramate, introduced as an antiepileptic drug (AED), is currently most widely used for prevention of migraine headaches.
Because reproductive-aged women represent a population in which migraines are prevalent, clinicians need guidance to help women taking topiramate make sound contraceptive choices.
Several issues are relevant here. First, women who have migraines with aura should avoid estrogen-containing contraceptive pills, patches, and rings. Instead, progestin-only methods, including the contraceptive implant, may be recommended to patients with migraines.
Second, because topiramate, as with a number of other AEDs, is a teratogen, women using this medication need highly effective contraception. This consideration may also lead clinicians to recommend use of the implant in women with migraines.
Finally, topiramate, along with other AEDs (phenytoin, carbamazepine, barbiturates, primidone, and oxcarbazepine) induces hepatic enzymes, which results in reduced serum contraceptive steroid levels.
Because there is uncertainty regarding the degree to which the use of topiramate reduces serum levels of etonogestrel (the progestin released by the implant), investigators performed a prospective study to assess the pharmacokinetic impact of topiramate in women with the implant.
Ongoing users of contraceptive implants who agreed to use additional nonhormonal contraception were recruited to a 6-week study, during which they took topiramate and periodically had blood drawn.
Overall, use of topiramate was found to lower serum etonogestrel levels from baseline on a dose-related basis. At study completion, almost one-third of study participants were found to have serum progestin levels lower than the threshold associated with predictable ovulation suppression.
The results of this carefully conducted study support guidance from the Centers for Disease Control and Prevention that women seeking contraception and using topiramate or other enzyme-inducing AEDs should be encouraged to use intrauterine devices or injectable contraception. The contraceptive efficacy of these latter methods is not diminished by concomitant use of enzyme inducers.

Antiseizure medication appears safe in pregnancy
SEATTLE – , according to new results from the Maternal Outcomes and Neurodevelopmental Effects of Antiepileptic Drugs (MONEAD) study.
The study follows results from the Neurodevelopmental Effects of Antiepileptic Drugs (NEAD) study, which found no evidence of cognitive harm in children who were exposed in utero to antiepileptic drugs. “[In the NEAD study] we followed our cohort to age 6 and found them to have actually an improvement in cognition by about 4 IQ points by the time they got to age 6,” Kimford J. Meador, MD, said during a presentation of the results of the MONEAD study at the 2022 annual meeting of the American Academy of Neurology.
Breastfeeding has health benefits for both mothers and children, including reduced risk of respiratory tract infections, atopic dermatitis, asthma, and diabetes in children, and reduced risk of diabetes, breast cancer, ovarian cancer, and postpartum depression in mothers. Despite those benefits, concerns about harms from exposure to antiepileptic drugs may prompt some women to avoid breastfeeding.
The results of NEAD and MONEAD should reassure patients, according to Dr. Meador, professor of neurology at Stanford (Calif.) University. “Given the known multiple benefits of breastfeeding … women with epilepsy should be encouraged to breastfeed,” he said.
A responsibility to ‘engage and educate’ patients
Jennifer Hopp, MD, who served as a discussant for the presentation, underscored the need for neurologists to address pregnancy with female patients of childbearing agents. “The issues may include fertility, peripartum management, and outcomes that really go through the lifespan to also include issues of menopause,” Dr. Hopp, associate professor of neurology at the University of Maryland, Baltimore, said during her presentation.
Dr. Hopp noted one study showing lower rates of breastfeeding among mothers with epilepsy. “Breastfeeding rates in women with epilepsy are strikingly lower than in women who do not have epilepsy,” said Dr. Hopp. Another study showed that women with epilepsy were less likely to sustain breastfeeding after 6 weeks.
Dr. Hopp implored neurologists to address this. “It’s our responsibility to engage and educate our patients. These data provide us messaging to our patients that the newer drugs do not adversely affect outcome independently of their other exposure, and really support well-informed choices in breastfeeding,” said Dr. Hopp.
Outdated attitudes still persist
Dr. Meador referred to the stigma that surrounds epilepsy, including some state laws that called for sterilization of women with epilepsy that lasted until the 1960s. One might think that such attitudes are gone, “but it’s still there,” said Dr. Meador, who recounted a story a colleague told him about a woman on antiseizure medication. In the hospital, the nurse told her not to breastfeed. The neurological consult told her not to breastfeed. She breastfed anyway. “Then they reported her for child neglect, and that was just a few years ago. So I think the message needs to be loud and clear that we encourage [women with epilepsy] to breastfeed because we have the known benefits, and now several studies showing clearly no adverse effects of breastfeeding while taking antiseizure medications,” said Dr. Meador.
MONEAD findings
The MONEAD study included women from 20 different sites, with 145 participating investigators. The researchers compared outcomes in 284 women with epilepsy and 87 healthy women. The maternal mean IQ was 98 among women with epilepsy (95% confidence interval [CI], 96-99), and 105 (95% CI, 102-107) among healthy women. Seventy-six percent of women with epilepsy breastfed, versus 89% of controls.
Among the study cohort, 79% of women with epilepsy were on monotherapy, and 21% were on polytherapy. Thirty-five percent received lamotrigine, 28% levetiracetam, 16% were on another monotherapy, 10% received a combination of lamotrigine and levetiracetam, and 11% received a different combination.
At age 3, there was no association between the verbal index score of the child and whether the mother had epilepsy or not (difference, 0.4; P = .770). The researchers did find associations with the mother’s IQ (0.3; P < .001), male versus female child sex (–4.9; P < .001), Hispanic or Latino ethnicity (vs. Non-Hispanic, –5.5; P < .001), mother without college degree (–7.0; P < .001), average Beck Anxiety Inventory score after birth (–0.4; P < .001), and weeks of gestational age at enrollment.
The researchers found no association between third trimester antiseizure medication blood levels and verbal index score after adjustment (–2.9; P = .149), with the exception of levetiracetam (–9.0; P = .033). “This is interesting (but) not to be overblown, because overall the children on levetiracetam did well. But it must be remembered that teratogens act in an exposure dependent manner, so we’re constantly in this balancing act of trying to make sure you get enough medication on board to stop the seizures and protect the mother and the child, and at the same time, not too much on board where we increase the risk of teratogenicity in the child,” said Dr. Meador.
The study was funded by the National Institutes of Health. Dr. Meador and Dr. Hopp have no relevant financial disclosures.

Psychotropic med use tied to ‘striking’ post-COVID dementia risk
, new research suggests.
Results from a large study of more than 1,700 patients who had been hospitalized with COVID showed a greater than twofold increased risk for post-COVID dementia in those taking antipsychotics and mood stabilizers/anticonvulsants – medications often used to treat schizophrenia, psychosis, bipolar disorder, and seizures.
“We know that pre-existing psychiatric illness is associated with poor COVID-19 outcomes, but our study is the first to show an association with certain psychiatric medications and dementia,” co-investigator Liron Sinvani, MD, the Feinstein Institutes for Medical Research, Manhasset, New York, said in an interview.
“Our study highlights the potential interaction between baseline neuropsychiatric disease, psychotropic medications, COVID-19, and dementia,” Dr. Sinvani added.
The findings were published online March 18 in Frontiers in Medicine.
‘Striking’ dementia rate
Using electronic health records, the researchers evaluated pre-COVID psychotropic medication use and post-COVID dementia onset in 1,755 adults aged 65 and older. All were hospitalized with COVID-19 at Northwell Health between March 1 and April 20, 2020.
A “striking” 13% of the participants (n = 223) developed dementia within 1-year of follow-up, the investigators report.
Among the 438 patients (25%) exposed to at least one psychotropic medication before COVID-19, 105 (24%) developed dementia in the year following COVID versus 118 of 1,317 (9%) patients with no pre-COVID exposure to psychotropic medication (odds ratio, 3.2; 95% confidence interval, 2.37-4.32).
Both pre-COVID psychotropic medication use (OR, 2.7; 95% CI, 1.8-4.0, P < .001) and delirium (OR, 3.0; 95% CI, 1.9-4.6, P < .001) were significantly associated with post-COVID dementia at 1 year.
In a sensitivity analysis in the subset of 423 patients with at least one documented neurologic or psychiatric diagnosis at the time of COVID admission, and after adjusting for confounding factors, pre-COVID psychotropic medication use remained significantly linked to post-COVID dementia onset (OR, 3.09; 95% CI, 1.5-6.6, P = .002).
Drug classes most strongly associated with 1-year post-COVID dementia onset were antipsychotics (OR, 2.8, 95% CI, 1.7-4.4, P < .001) and mood stabilizers/anticonvulsants (OR, 2.4, 95% CI, 1.39-4.02, P = .001).
In a further exploratory analysis, the psychotropics valproic acid (multiple brands) and haloperidol (Haldol) had the largest association with post-COVID dementia.
Antidepressants as a class were not associated with post-COVID dementia, but the potential effects of two commonly prescribed antidepressants in older adults, mirtazapine (Remeron) and escitalopram (Lexapro), “warrant further investigation,” the researchers note.
Predictive risk marker?
“This research shows that psychotropic medications can be considered a predictive risk marker for post-COVID dementia. In patients taking psychotropic medications, COVID-19 could have accelerated progression of dementia after hospitalization,” lead author Yun Freudenberg-Hua, MD, the Feinstein Institutes, said in a news release.
It is unclear why psychotropic medications may raise the risk for dementia onset after COVID, the investigators note.
“It is intuitive that psychotropic medications indicate pre-existing neuropsychiatric conditions in which COVID-19 occurs. It is possible that psychotropic medications may potentiate the neurostructural changes that have been found in the brain of those who have recovered from COVID-19,” they write.
The sensitivity analysis in patients with documented neurologic and psychiatric diagnoses supports this interpretation.
COVID-19 may also accelerate the underlying brain disorders for which psychotropic medications were prescribed, leading to the greater incidence of post-COVID dementia, the researchers write.
“It is important to note that this study is in no way recommending people should stop taking antipsychotics but simply that clinicians need to factor in a patient’s medication history while considering post-COVID aftereffects,” Dr. Freudenberg-Hua said.
“Given that the number of patients with dementia is projected to triple in the next 30 years, these findings have significant public health implications,” Dr. Sinvani added.
She noted that “care partners and health care professionals” should look for early signs of dementia, such as forgetfulness and depressive symptoms, in their patients.
“Future studies must continue to evaluate these associations, which are key for potential future interventions to prevent dementia,” Dr. Sinvani said.
The study was funded by the National Institutes of Health. Dr. Freudenberg-Hua co-owns stock and stock options from Regeneron Pharmaceuticals. Dr. Sinvani has disclosed no relevant financial relationships.

In a sensitivity analysis in the subset of 423 patients with at least one documented neurologic or psychiatric diagnosis at the time of COVID admission, and after adjusting for confounding factors, pre-COVID psychotropic medication use remained significantly linked to post-COVID dementia onset (OR, 3.09; 95% CI, 1.5-6.6, P = .002).
Drug classes most strongly associated with 1-year post-COVID dementia onset were antipsychotics (OR, 2.8, 95% CI, 1.7-4.4, P < .001) and mood stabilizers/anticonvulsants (OR, 2.4, 95% CI, 1.39-4.02, P = .001).
In a further exploratory analysis, the psychotropics valproic acid (multiple brands) and haloperidol (Haldol) had the largest association with post-COVID dementia.
Antidepressants as a class were not associated with post-COVID dementia, but the potential effects of two commonly prescribed antidepressants in older adults, mirtazapine (Remeron) and escitalopram (Lexapro), “warrant further investigation,” the researchers note.
Predictive risk marker?
“This research shows that psychotropic medications can be considered a predictive risk marker for post-COVID dementia. In patients taking psychotropic medications, COVID-19 could have accelerated progression of dementia after hospitalization,” lead author Yun Freudenberg-Hua, MD, the Feinstein Institutes, said in a news release.
It is unclear why psychotropic medications may raise the risk for dementia onset after COVID, the investigators note.
“It is intuitive that psychotropic medications indicate pre-existing neuropsychiatric conditions in which COVID-19 occurs. It is possible that psychotropic medications may potentiate the neurostructural changes that have been found in the brain of those who have recovered from COVID-19,” they write.
The sensitivity analysis in patients with documented neurologic and psychiatric diagnoses supports this interpretation.
COVID-19 may also accelerate the underlying brain disorders for which psychotropic medications were prescribed, leading to the greater incidence of post-COVID dementia, the researchers write.
“It is important to note that this study is in no way recommending people should stop taking antipsychotics but simply that clinicians need to factor in a patient’s medication history while considering post-COVID aftereffects,” Dr. Freudenberg-Hua said.
“Given that the number of patients with dementia is projected to triple in the next 30 years, these findings have significant public health implications,” Dr. Sinvani added.
She noted that “care partners and health care professionals” should look for early signs of dementia, such as forgetfulness and depressive symptoms, in their patients.
“Future studies must continue to evaluate these associations, which are key for potential future interventions to prevent dementia,” Dr. Sinvani said.
The study was funded by the National Institutes of Health. Dr. Freudenberg-Hua co-owns stock and stock options from Regeneron Pharmaceuticals. Dr. Sinvani has disclosed no relevant financial relationships.

New guidance on cannabis use for treatment-resistant epilepsy
A recent review article draws from existing clinical trials and clinical experience in New South Wales, Australia, to fill this gap with interim guidance for both pediatric and adult patients. The article was published in the British Journal of Clinical Pharmacology.
The only current U.S. guidelines are from the American Academy of Neurology’s position statement on the use of medical cannabis for neurologic disorders and the American Epilepsy Society’s position statement on cannabis as a treatment for epileptic seizures. The AAN statement “highlights the current evidence, which currently only supports [Food and Drug Administration]–approved CBD [cannabidiol] (Epidiolex) for specific epilepsy syndromes,” said Daniel Freedman, DO, an assistant professor of neurology at the University of Texas at Austin and coauthor of the AAN’s position statement.
“Rescheduling marijuana will enable researchers to study CBD, THC [tetrahydrocannabinol], and other cannabinoids in high-quality studies so that we can better understand what works and for which conditions,” said Dr. Freedman, who was not involved in the Australian guidance document. He noted that little consensus exists because little evidence exists outside the handful of trials for Epidiolex.
“There are some patients with epilepsy that can benefit from high-quality, pharmaceutical-grade CBD products,” Dr. Freedman said. “These patients need to be carefully identified by a neurologist or epileptologist and prescribed a legal, safe, quality-controlled, and FDA-regulated product.”
Appropriate patient populations
Drug-resistant epilepsy, defined as failure of two appropriate antiseizure medications, affects an estimated one third of people with epilepsy, the new guideline notes. Though many over-the-counter products are available at dispensaries in the 33 U.S. states that allow use of cannabis for medical purposes, Epidiolex (cannabidiol) is the only FDA-approved drug for epilepsy that contains a substance derived from cannabis and the only one for which evidence from randomized, controlled trials exists.
Dr. Freedman notes that hemp-derived CBD oils are classified differently in the United States than marijuana-derived CBD oil, including Epidiolex, and are loosely regulated supplements or food additives commonly seen, for example at gas station.
“The point I drive home to patients is that you wouldn’t get your antibiotics from a gas station, so please don’t get your seizure medication from there,” Dr. Freedman said. “Studies have been done on ‘over-the-counter’ CBD oils and shown that they have variable quality, sometimes no detectable CBD, and sometimes other chemicals added like THC.”
Studies of Epidiolex showed that cannabidiol more effectively reduced seizure frequency than placebo for pediatric patients with Dravet syndrome (42% reduction) and for pediatric and adult patients with Lennox-Gastaut syndrome (39% reduction) or tuberous sclerosis complex (49% reduction). Efficacy was similar across dosing from 10-50 mg/kg per day, but higher doses involved higher rates of serious adverse events.
No reliable evidence in humans exists for THC or other cannabinoids in treating epilepsy.
The Australian guidance recommends limiting cannabis treatment to patients with severe drug-resistant epilepsy; a diagnosis of Dravet syndrome, Lennox-Gastaut syndrome, or tuberous sclerosis complex; and previous treatment with four approved antiseizure medications and/or the ketogenic diet, epilepsy surgery, or neurostimulator. The authors provide specific criteria for each of these conditions and then address exceptional cases that may be considered outside that criteria, such as patients under 2 years old, severe epilepsy with extended or repeated hospitalization or ICU admission, or a dangerous seizure type. The review also includes a detailed list of exclusion criteria for CBD medicine use.
The authors advised a thorough consent process before prescribing any cannabinoids, including therapeutic goals and stopping criteria; the lack of evidence available on dosing, efficacy, and side effects; and the potential for dependence or withdrawal. Consent discussions should also note whether the products are unregistered and not covered by external payers (anything other than Epidiolex currently), any activity restrictions, and any implications for occupational drug screening.
Considerations for unapproved cannabinoids
The authors note several factors to consider if prescribing or recommending a nonapproved, nonregulated cannabis medicine, including the ”differences between registered plant-derived cannabis medicines, synthetic cannabis medicines, and unregistered hemp-derived products.” Epidiolex is plant derived while other cannabis-derived medications (Marinol, Syndos, and Cesamet) that have been approved for nonepilepsy conditions, such as nausea associated with chemotherapy, are synthetic.
The guidance document notes several reasons to use a regulated medication instead of an unregulated product:
- Manufacturing processes can differ for unregulated products, including inconsistency in batches and unknown shelf life.
- Quality control processes, including risk of impurities, are much better with regulated products, which also have a system in place for safety recalls.
- More scientific evidence is available for regulated products.
- Safety surveillance reporting is more robust and standardized for regulated products whereas adverse event reporting is less reliable for unregulated products.
- Nonregulated products are rarely covered by insurance or other reimbursement.
Legal considerations will also vary by jurisdiction. ”Right now in the U.S. we have a confused legality where state level programs are still technically illegal at the federal level and I imagine there are some quality differences amongst dispensaries and states,” Dr. Freedman said. “Whenever there is disagreement between state and federal laws, this creates tension for our patients.” He noted, for example, that a patient using a CBD product that contains THC may, even if legal in their state, be confiscated by the Transportation Security Administration at an airport since it is not FDA approved and is not legal, according to the Drug Enforcement Agency.
The authors noted that inadequate data on long-term CBD use and data on neurodevelopmental effects of THC in children, teens, and young adults means THC products should be contraindicated for these age groups. (Epidiolex has less than 2% THC.) Drug interactions should also be considered, particularly for clobazam, CYP3A4 inhibitors or inducers (including St. John’s wort), digoxin, or a mechanistic target of rapamycin inhibitor.
Dr. Freedman said that most neurologists are comfortable prescribing Epidiolex since it has FDA approval while prescribing unapproved products varies more in the field. “Now that many states have compassionate use programs for medical marijuana, some neurologists do this as well,” Dr. Freedman said. Patients often ask about unregulated CBD or CBD+THC products because they’re seen as “natural and therefore better than manufactured pharmaceuticals.”
“I think this is the naturalistic fallacy at work and try to educate my patients on that since our only high-level data to show marijuana products work for epilepsy comes from a pharmaceutical company,” Dr. Freedman said. “My reasons for hesitating on compassionate use are that there is often THC, with variable amounts of concentration, and we know that THC can harm the developing pediatric brain.”
Dosing and adverse effects
Pediatric and adult dosing differences need to be considered, and “patient response (efficacy and toxicity) to these medications varies widely,” the authors noted. They advised getting serum transaminases (ALT and AST) and total bilirubin levels before beginning treatment. All patients should begin Epidiolex at a low dose, such as 2-5 mg/kg per day of CBD in two divided doses, the authors advise, and titrate slowly while monitoring for side effects (no more than 5 mg/kg per day per week). The current dosing range for CBD is 5-20 mg/kg per day in two divided doses, with higher rates involving more risk of adverse events.
“Note that some cannabinoids auto-inhibit their own metabolism and some have active metabolites with longer half-lives,” the authors wrote. “Therefore, dose or frequency may need to be reduced over time, unless tolerance occurs.” These doses, specific to Epidiolex, “cannot necessarily be applied to other oral CBD formulations or other types of epilepsy.” This guidance also does not apply to inhaled or transdermal routes of administration.
The most common adverse events were sleepiness – which occurred in up to 60% of trial participants – as well as diarrhea, decreases in appetite and weight, and drug interactions. Risk of hepatotoxicity means there’s a need to monitor liver function and adjust dosing for patients with moderate or severe hepatic impairment. “Other short-term side effects reported only with THC-containing cannabinoid compounds include increased risk of cardiac and cerebrovascular events, anxiety and psychosis risk, dependency, and withdrawal,” the authors wrote.
Though no withdrawal syndrome has been linked to stopping CBD, the authors suggested decreasing the dose by 10% every 2 days if stopping is not urgent.
“The key points to this issue are that CBD and all marijuana products need to be safe and regulated,” Dr. Freedman said. “Any claims about them need to be backed by high-quality evidence looking at that specific product for that specific condition.”
Dr. Freedman noted the need for children to receive treatment from clinicians with expertise in their specific condition since many other evidence-based treatments exist even for patients with epilepsy syndromes that are difficult to treat, such as other medications, surgery, and specialized diets.
“We need to fix the inconsistent regulation between over-the-counter CBD products, state dispensaries, and federal laws,” Dr. Freedman added. “Any medicine being used to treat children should be held to the same FDA standard of safety and efficacy.”
Dr. Freedman and the authors had no conflicts of interest. No external funding was noted.

FROM THE BRITISH JOURNAL OF CLINICAL PHARMACOLOGY
Seizure phobia stands out in epilepsy patients
Anxiety and depression are known to affect quality of life in epilepsy patients, and previous studies have shown that anticipatory anxiety of epileptic seizures (AAS) was present in 53% of patients with focal epilepsy, wrote lead author Aviva Weiss of Psychiatric Hostels affiliated with Kidum Rehabilitation Projects, Jerusalem, and colleagues.
“Although recognized by the epilepsy and the psychiatric communities, seizure phobia as a distinct anxiety disorder among PWE is insufficiently described in the medical literature,” they said.
Seizure phobia has been defined as an anxiety disorder in which patients experience fear related to anticipation of seizures in certain situations.
In a study published in Seizure: European Journal of Epilepsy, the researchers recruited 69 PWE who were treated at an outpatient clinic. Data were collected from interviews, questionnaires, and medical records. The average age of the participants was 36.8 years, 41 were women, and 41 were married.
Overall, 19 individuals (27.5%) were diagnosed with seizure phobia. Compared with PWE without seizure phobia, the seizure phobia patients were significantly more likely to be women (84.2% vs. 44.2%; P = .005) and to have comorbid anxiety disorders (84.2% vs. 34.9%; P = .01). Individuals with seizure phobia also were significantly more likely than those without seizure phobia to have a past major depressive episode (63.2% vs. 20.9%; P = .003), and posttraumatic stress disorder (26.3% vs. 7%; P = .05).
Seizure phobia was significantly associated with comorbid psychogenic nonepileptic seizures (PNES) (36.8% vs. 11.6%; P = .034). PNES have been significantly associated with panic attacks, and “all patients with both panic attacks and comorbid PNES were diagnosed with seizure phobia,” the researchers noted. However, no significant association was found with epilepsy-related variables, they said.
A multivariate logistic regression model to predict seizure phobia showed that anxiety and a past MDE were significant predictors; the odds of seizure phobia were 10.45 times higher if a patient reported any anxiety disorder, and 6.85 times higher if the patient had a history of MDE.
The study findings were limited by several factors, including the use of semistructured interviews to diagnose seizure phobia, which are subject to interviewer bias, and by the small study population with a high proportion of comorbid PNES and epilepsy, the researchers noted. However, the results support seizure phobia as a distinct clinical entity worthy of management with education, psychosocial interventions, and potential medication changes, they said.
“Development of appropriate screening tools and implementation of effective treatment interventions is warranted for individual patients, combined with large-scale population-targeted psychoeducation, aimed to mitigate the risk of developing seizure phobia in PWE,” they concluded.
The study received no outside funding. The researchers had no financial conflicts to disclose.

A multivariate logistic regression model to predict seizure phobia showed that anxiety and a past MDE were significant predictors; the odds of seizure phobia were 10.45 times higher if a patient reported any anxiety disorder, and 6.85 times higher if the patient had a history of MDE.
The study findings were limited by several factors, including the use of semistructured interviews to diagnose seizure phobia, which are subject to interviewer bias, and by the small study population with a high proportion of comorbid PNES and epilepsy, the researchers noted. However, the results support seizure phobia as a distinct clinical entity worthy of management with education, psychosocial interventions, and potential medication changes, they said.
“Development of appropriate screening tools and implementation of effective treatment interventions is warranted for individual patients, combined with large-scale population-targeted psychoeducation, aimed to mitigate the risk of developing seizure phobia in PWE,” they concluded.
The study received no outside funding. The researchers had no financial conflicts to disclose.
Anxiety and depression are known to affect quality of life in epilepsy patients, and previous studies have shown that anticipatory anxiety of epileptic seizures (AAS) was present in 53% of patients with focal epilepsy, wrote lead author Aviva Weiss of Psychiatric Hostels affiliated with Kidum Rehabilitation Projects, Jerusalem, and colleagues.
“Although recognized by the epilepsy and the psychiatric communities, seizure phobia as a distinct anxiety disorder among PWE is insufficiently described in the medical literature,” they said.
Seizure phobia has been defined as an anxiety disorder in which patients experience fear related to anticipation of seizures in certain situations.
In a study published in Seizure: European Journal of Epilepsy, the researchers recruited 69 PWE who were treated at an outpatient clinic. Data were collected from interviews, questionnaires, and medical records. The average age of the participants was 36.8 years, 41 were women, and 41 were married.
Overall, 19 individuals (27.5%) were diagnosed with seizure phobia. Compared with PWE without seizure phobia, the seizure phobia patients were significantly more likely to be women (84.2% vs. 44.2%; P = .005) and to have comorbid anxiety disorders (84.2% vs. 34.9%; P = .01). Individuals with seizure phobia also were significantly more likely than those without seizure phobia to have a past major depressive episode (63.2% vs. 20.9%; P = .003), and posttraumatic stress disorder (26.3% vs. 7%; P = .05).
Seizure phobia was significantly associated with comorbid psychogenic nonepileptic seizures (PNES) (36.8% vs. 11.6%; P = .034). PNES have been significantly associated with panic attacks, and “all patients with both panic attacks and comorbid PNES were diagnosed with seizure phobia,” the researchers noted. However, no significant association was found with epilepsy-related variables, they said.

ILAE offers first guide to treating depression in epilepsy
The new guidance highlights the high prevalence of depression among patients with epilepsy while offering the first systematic approach to treatment, reported lead author Marco Mula, MD, PhD, of Atkinson Morley Regional Neuroscience Centre at St George’s University Hospital, London, and colleagues.
“Despite evidence that depression represents a frequently encountered comorbidity [among patients with epilepsy], data on the treatment of depression in epilepsy [are] still limited and recommendations rely mostly on individual clinical experience and expertise,” the investigators wrote in Epilepsia.
Recommendations cover first-line treatment of unipolar depression in epilepsy without other psychiatric disorders.
For patients with mild depression, the guidance supports psychological intervention without pharmacologic therapy; however, if the patient wishes to use medication, has had a positive response to medication in the past, or nonpharmacologic treatments have previously failed or are unavailable, then SSRIs should be considered first-choice therapy. For moderate to severe depression, SSRIs are the first choice, according to Dr. Mula and colleagues.
“It has to be acknowledged that there is considerable debate in the psychiatric literature about the treatment of mild depression in adults,” the investigators noted. “A patient-level meta-analysis pointed out that the magnitude of benefit of antidepressant medications compared with placebo increases with severity of depression symptoms and it may be minimal or nonexistent, on average, in patients with mild or moderate symptoms.”
If a patient does not respond to first-line therapy, then venlafaxine should be considered, according to the guidance. When a patient does respond to therapy, treatment should be continued for at least 6 months, and when residual symptoms persist, treatment should be continued until resolution.
“In people with depression it is established that around two-thirds of patients do not achieve full remission with first-line treatment,” Dr. Mula and colleagues wrote. “In people with epilepsy, current data show that up to 50% of patients do not achieve full remission from depression. For this reason, augmentation strategies are often needed. They should be adopted by psychiatrists, neuropsychiatrists, or mental health professionals familiar with such therapeutic strategies.”
Beyond these key recommendations, the guidance covers a range of additional topics, including other pharmacologic options, medication discontinuation strategies, electroconvulsive therapy, light therapy, exercise training, vagus nerve stimulation, and repetitive transcranial magnetic stimulation.
Useful advice that counters common misconceptions
According to Jacqueline A. French, MD, a professor at NYU Langone Medical Center, Dr. Mula and colleagues are “top notch,” and their recommendations “hit every nail on the head.”
Dr. French, chief medical officer of The Epilepsy Foundation, emphasized the importance of the publication, which addresses two common misconceptions within the medical community: First, that standard antidepressants are insufficient to treat depression in patients with epilepsy, and second, that antidepressants may trigger seizures.
“The first purpose [of the publication] is to say, yes, these antidepressants do work,” Dr. French said, “and no, they don’t worsen seizures, and you can use them safely, and they are appropriate to use.”
Dr. French explained that managing depression remains a practice gap among epileptologists and neurologists because it is a diagnosis that doesn’t traditionally fall into their purview, yet many patients with epilepsy forgo visiting their primary care providers, who more frequently diagnose and manage depression. Dr. French agreed with the guidance that epilepsy specialists should fill this gap.
“We need to at least be able to take people through their first antidepressant, even though we were not trained to be psychiatrists,” Dr. French said. “That’s part of the best care of our patients.”
Imad Najm, MD, director of the Charles Shor Epilepsy Center, Cleveland Clinic, said the recommendations are a step forward in the field, as they are supported by clinical data, instead of just clinical experience and expertise.
Still, Dr. Najm noted that more work is needed to stratify risk of depression in epilepsy and evaluate a possible causal relationship between epilepsy therapies and depression.
He went on to emphasizes the scale of issue at hand, and the stakes involved.
“Depression, anxiety, and psychosis affect a large number of patients with epilepsy,” Dr. Najm said. “Clinical screening and recognition of these comorbidities leads to the institution of treatment options and significant improvement in quality of life. Mental health professionals should be an integral part of any comprehensive epilepsy center.”
The investigators disclosed relationships with Esai, UCB, Elsevier, and others. Dr. French is indirectly involved with multiple pharmaceutical companies developing epilepsy drugs through her role as director of The Epilepsy Study Consortium, a nonprofit organization. Dr. Najm reported no conflicts of interest.
