NIH to study COVID vaccine booster in people with autoimmune disease
In the wake of the Centers for Disease Control and Prevention’s recommendation for a third COVID-19 mRNA vaccine dose for immunocompromised people and the Food and Drug Administration’s authorization of the third dose, the according to an announcement.
The investigators of the trial, called COVID‐19 Booster Vaccine in Autoimmune Disease Non‐Responders, also want to determine if pausing immunosuppressive therapy for autoimmune disease improves the antibody response to an extra dose of a COVID-19 vaccine.
The trial will specifically look at the effects of mycophenolate mofetil (MMF) or mycophenolic acid (MPA), and methotrexate (MTX), or receipt of B cell–depletion therapy such as rituximab within the past 12 months on immune response to a booster dose in people with systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis, systemic sclerosis, or pemphigus. They have to have either no serologic response to their initial COVID-19 vaccine regimen or a suboptimal response, defined as a Roche Elecsys Anti-SARS-CoV-2 S (RBD) result greater than or equal to 50 U/mL.
The results of studies conducted in solid-organ transplant recipients who take immunosuppressants showed that an extra dose of vaccine could improve the immune response to the vaccine in many of the individuals, which suggests that the same approach might work in people with autoimmune disease who need treatment with immunosuppressive drugs. Improving the immune response of people with autoimmune disease to COVID-19 vaccines is important because higher rates of severe COVID-19 and death have been reported in this group of patients than in the general population, and it is unclear whether this is attributable to the autoimmune disease, the immunosuppressive medications taken to treat it, or both.
The open-label trial, conducted by the NIAID-funded Autoimmunity Centers of Excellence, aims to enroll 600 people aged 18 years and older with those conditions at 15-20 sites in the United States.
Because medications commonly taken by people with these conditions have been associated with poorer immune responses to vaccines, the trial will randomize the following two cohorts to stop or continue taking their immunosuppressive medication(s) or stop them before and after the booster according to protocol:
- Cohort 1 includes people who are taking MMF or MPA, without additional B cell–depleting medications or MTX.
- Cohort 2 includes people who are taking MTX without additional B cell–depleting medications or MMF/MPA.
A third, nonrandomized cohort consists of people who have received B cell–depletion therapy within the past 12 months regardless of whether they are also taking MMF/MPA or MTX.
Besides the cohort-specific exclusions, other rheumatic disease medications, including biologics, are allowed in the groups.
The primary outcome of the trial is the proportion of participants who have a protective antibody response at week 4. Secondary outcomes will examine various antibody responses at intervals, changes in disease activity across autoimmune diseases, adverse events, and SARS-CoV-2 infections out to 48 weeks.
Study participants will be followed for a total of 13 months. Preliminary results are expected in November 2021, according to the National Institutes of Health.
The trial is being led by Judith James, MD, PhD; Meggan Mackay, MD, MS; Dinesh Khanna, MBBS, MSc; and Amit Bar-Or, MD.

Neurodegenerative nature of schizophrenia makes case for LAIs
Schizophrenia is a complex disease caused by dysfunction in specific brain regions or circuits. In fact, schizophrenia is not a single disease but several hundred different diseases, according to Henry A. Nasrallah, MD, who spoke on the topic at a virtual meeting presented by Current Psychiatry and the American Academy of Clinical Psychiatrists.
The underlying causes of schizophrenia can be either genetic or environmental, but all involve changes in brain development in the fetus or newborn. Psychosis can occur in a range of disorders, including epilepsy, Parkinson’s disease, cerebral tumors, and narcolepsy, to name just a few. Although it starts out as a neurodevelopmental disorder, schizophrenia becomes neurodegenerative after onset, with each new psychotic episode leading to further damage, said Dr. Nasrallah, professor of psychiatry, neurology, and neuroscience at the University of Cincinnati. Further damage leaves patients with greater and greater disability over time, said Dr. Nasrallah at the meeting presented by MedscapeLive. MedscapeLive and this news organization are owned by the same parent company.
The course of illness in some ways resembles the cascading disability associated with strokes. Schizophrenia relapses lead to subcortical atrophy, ventricular enlargement, and further loss of white matter. The accumulating damage is a result of microglia activation, which leads to neuroinflammation and oxidative stress. Mitochondria may also produce insufficient amounts of the antioxidant glutathione.
“The main reason for relapse in schizophrenia is poor adherence to antipsychotic medications, due to anosognosia, memory impairment, avolition, and substance use. It is absolutely necessary to realize that, while oral antipsychotics are effective in the hospital due to enforced compliance by the nursing staff, patients should be switched to long-acting injectable antipsychotics (LAIs) upon discharge from the first episode, which astonishingly is rarely done by 99% of clinicians,” said Dr. Nasrallah in an interview.
That frequent failure leads to further neurodegeneration and increasing disability, which in turn can lead to high rates of homelessness, suicide, and as well as incarceration, because many state hospitals that used to provide medical care for relapsing individuals have been closed down. All of these consequences place great financial and emotional burdens on families and loved ones.
Reconceptualizing the illness
Dr. Nasrallah also advocated that schizophrenia should be classified as a neurologic disorder instead of a psychiatric disorder. He said that the neuropsychiatric mechanisms behind these related diseases support that classification, and neurologic disorders receive much more insurance coverage.
The neuroinflammatory mechanisms underlying schizophrenia suggest that therapies such as omega-3 fatty acids could provide benefit during the prodromal stages of illness. Antioxidants like N-acetyl cysteine could potentially be useful during psychotic episodes, since it boosts levels of glutathione to reduce damaging free radicals. Other approaches could prevent microglia activation, which appears to initiate neurodegeneration.
Another consequence of psychosis is programmed cell death, or apoptosis, in response to reduced levels of neurotropic agents. That could potentially be countered using agents to prevent apoptosis.
Dr. Nasrallah believes clinicians should not use first-generation antipsychotics such as haloperidol, because research has shown that those drugs, while effective, also destroy neurons. Second-generation antipsychotics (SGAs) are safer and avoid that neurotoxicity, and they also have a neuroprotective effect. The SGAs may owe their improved efficacy and safety to the fact that they don’t bind as strongly to dopamine receptors, and they are stronger 5-hydroxytryptamine2A antagonists, according to Dr. Nasrallah. A meta-analysis of 18 studies showed that patients on SGAs maintained gray matter volume, and may even achieve increases in the hippocampus and the prefrontal cortex.
In the Q&A session after the presentation, Dr. Nasrallah was asked whether treatment should be kept up for the rest of the patient’s life, or whether medication should be tapered – and perhaps stopped. He likened treatment of schizophrenia to diabetes or high blood pressure.
“It’s an illness. A lot of medical disorders require lifetime treatment, and there is no difference between psychiatry and the rest of medicine,” he said. “You have to continue the medication at the dose that worked in the acute episode, hopefully the lowest possible dose.”
Dr. Nasrallah did concede that it can be challenging to get patients to accept permanent treatment, and he shared his own strategy to achieve that outcome. “I don’t tell the patient, ‘You’re going to take this the rest of your life.’ It depresses them. So I say, ‘Let’s keep this on board for a year, and I’ll see you regularly, and I’ll monitor you, and we’ll see how it goes, and then we will make another decision at the end of the year.’ ”
During that year, Dr. Nasrallah educates the patient and develops a rapport. “I will show them a lot of data and information about the illness and the hazards of stopping [treatment]. And by the end of the year, most of my patients say: ‘Yeah, I agree. Let’s continue the good thing and let’s not fix something that’s not broken.’ ”
Dr. Nasrallah has consulted for Acadia, Alkermes, Allergan, Boehringer-Ingelheim, Indivior, Intra-Cellular, Janssen, Neurocrine, Otsuka, Sunovion, and Teva. He has also served on a speaker’s bureau for most of those companies, in addition to that of Noven.

REPORTING FROM FOCUS ON NEUROPSYCHIATRY 2021
Nonmotor symptoms common in Parkinson’s
The hallmark of Parkinson’s disease is the accompanying motor symptoms, but the condition can bring other challenges. Among those are nonmotor symptoms, including depression, dementia, and even psychosis.
The culprit is Lewy bodies, which are also responsible for Lewy body dementia. “What we call Lewy body dementia and Parkinson’s disease are caused by the same pathological process – the formation of Lewy bodies in the brain,” Leslie Citrome, MD, MPH, said in an interview. Dr. Citrome discussed some of the psychiatric comorbidities associated with Parkinson’s disease at a virtual meeting presented by Current Psychiatry and the American Academy of Clinical Psychiatrists.
In fact, the association goes both ways. “Many people with Parkinson’s disease develop a dementia. Many people with Lewy body dementia develop motor symptoms that look just like Parkinson’s disease,” said Dr. Citrome, professor of psychiatry and behavioral sciences at New York Medical College, Valhalla, and president of the American Society for Clinical Psychopharmacology.
The motor symptoms of Parkinson’s disease are generally attributable to loss of striatal dopaminergic neurons, while nonmotor symptoms can be traced to loss of neurons in nondopaminergic regions. Nonmotor symptoms – often including sleep disorders, depression, cognitive changes, and psychosis – may occur before motor symptoms. Other problems may include autonomic dysfunction, such as constipation, sexual dysfunction, sweating, or urinary retention.
Patients might not be aware that nonmotor symptoms can occur with Parkinson’s disease and may not even consider mentioning mood changes or hallucinations to their neurologist. Family members may also be unaware.
Sleep problems are common in Parkinson’s disease, including rapid eye-movement sleep behavior disorders, vivid dreams, restless legs syndrome, insomnia, and daytime somnolence. Dopamine agonists may also cause unintended sleep.
Depression is extremely common, affecting up to 90% of Parkinson’s disease patients, and this may be related to dopaminergic losses. Antidepressant medications can worsen Parkinson’s disease symptoms: Tricyclic antidepressants increase risk of adverse events from anticholinergic drugs. Selective serotonin reuptake inhibitors (SSRIs) can exacerbate tremor and may increase risk of serotonin syndrome when combined with MAO‐B inhibitors.
Dr. Citrome was not aware of any antidepressant drugs that have been tested specifically in Parkinson’s disease patients, though “I’d be surprised if there wasn’t,” he said during the Q&A session. “There’s no one perfect antidepressant for people with depression associated with Parkinson’s disease. I would make sure to select one that they would tolerate and be willing to take and that doesn’t interfere with their treatment of their movement disorder, and (I would make sure) that there’s no drug-drug interaction,” he said.
This can include reduced working memory, learning, and planning, and generally does not manifest until at least 1 year after motor symptoms have begun. Rivastigmine is Food and Drug Administration–approved for treatment of cognitive impairment in Parkinson’s disease.
As many as 60% of Parkinson’s disease patients suffer from psychosis at some point, often visual hallucinations or delusions, which can include beliefs of spousal infidelity.
Many clinicians prescribe quetiapine off label, but there are not compelling data to support that it reduces intensity and frequency of hallucinations and delusions, according to Dr. Citrome. However, it is relatively easy to prescribe, requiring no preauthorizations, it is inexpensive, and it may improve sleep.
The FDA approved pimavanserin in 2016 for hallucinations and delusions in Parkinson’s disease, and it doesn’t worsen motor symptoms, Dr. Citrome said. That’s because pimavanserin is a highly selective antagonist of the 5-HT2A receptor, with no effect on dopaminergic, histaminergic, adrenergic, or muscarinic receptors.
The drug improves positive symptoms beginning at days 29 and 43, compared with placebo. An analysis by Dr. Citrome’s group found a number needed to treat (NNT) of 7 to gain a benefit over placebo if the metric is a ≥ 30% reduction in baseline symptom score. The drug had an NNT of 9 to achieve a ≥ 50% reduction, and an NNT of 5 to achieve a score of much improved or very much improved on the Clinical Global Impression–Improvement (CGI-I) scale. In general, an NNT less than 10 suggests that a drug is clinically useful.
In contrast, the number needed to harm (NNH) represents the number of patients who would need to receive a therapy to add one adverse event, compared with placebo. A number greater than 10 indicates that the therapy may be tolerable.
Using various measures, the NNH was well over 10 for pimavanserin. With respect to somnolence, the NNH over placebo was 138, and for a weight gain of 7% or more, the NNH was 594.
Overall, the study found that 4 patients would need to be treated to achieve a benefit over placebo with respect to a ≥ 3–point improvement in the Scale of Positive Symptoms–Parkinson’s Disease (SAPS-PD), while 21 would need to receive the drug to lead to one additional discontinuation because of an adverse event, compared to placebo.
When researchers compared pimavanserin to off-label use of quetiapine, olanzapine, and clozapine, they found a Cohen’s d value of 0.50, which was better than quetiapine and olanzapine, but lower than for clozapine. However, there is no requirement of blood monitoring, and clozapine can potentially worsen motor symptoms.
Dr. Citrome’s presentation should be a reminder to neurologists that psychiatric disorders are an important patient concern, said Henry A. Nasrallah, MD, professor of psychiatry, neurology, and neuroscience at the University of Cincinnati, who moderated the session.
“I think this serves as a model to recognize that many neurological disorders actually present with numerous psychiatric disorders,” Dr. Nasrallah said during the meeting, presented by MedscapeLive. MedscapeLive and this news organization are owned by the same parent company.

This can include reduced working memory, learning, and planning, and generally does not manifest until at least 1 year after motor symptoms have begun. Rivastigmine is Food and Drug Administration–approved for treatment of cognitive impairment in Parkinson’s disease.
As many as 60% of Parkinson’s disease patients suffer from psychosis at some point, often visual hallucinations or delusions, which can include beliefs of spousal infidelity.
Many clinicians prescribe quetiapine off label, but there are not compelling data to support that it reduces intensity and frequency of hallucinations and delusions, according to Dr. Citrome. However, it is relatively easy to prescribe, requiring no preauthorizations, it is inexpensive, and it may improve sleep.
The FDA approved pimavanserin in 2016 for hallucinations and delusions in Parkinson’s disease, and it doesn’t worsen motor symptoms, Dr. Citrome said. That’s because pimavanserin is a highly selective antagonist of the 5-HT2A receptor, with no effect on dopaminergic, histaminergic, adrenergic, or muscarinic receptors.
The drug improves positive symptoms beginning at days 29 and 43, compared with placebo. An analysis by Dr. Citrome’s group found a number needed to treat (NNT) of 7 to gain a benefit over placebo if the metric is a ≥ 30% reduction in baseline symptom score. The drug had an NNT of 9 to achieve a ≥ 50% reduction, and an NNT of 5 to achieve a score of much improved or very much improved on the Clinical Global Impression–Improvement (CGI-I) scale. In general, an NNT less than 10 suggests that a drug is clinically useful.
In contrast, the number needed to harm (NNH) represents the number of patients who would need to receive a therapy to add one adverse event, compared with placebo. A number greater than 10 indicates that the therapy may be tolerable.
Using various measures, the NNH was well over 10 for pimavanserin. With respect to somnolence, the NNH over placebo was 138, and for a weight gain of 7% or more, the NNH was 594.
Overall, the study found that 4 patients would need to be treated to achieve a benefit over placebo with respect to a ≥ 3–point improvement in the Scale of Positive Symptoms–Parkinson’s Disease (SAPS-PD), while 21 would need to receive the drug to lead to one additional discontinuation because of an adverse event, compared to placebo.
When researchers compared pimavanserin to off-label use of quetiapine, olanzapine, and clozapine, they found a Cohen’s d value of 0.50, which was better than quetiapine and olanzapine, but lower than for clozapine. However, there is no requirement of blood monitoring, and clozapine can potentially worsen motor symptoms.
Dr. Citrome’s presentation should be a reminder to neurologists that psychiatric disorders are an important patient concern, said Henry A. Nasrallah, MD, professor of psychiatry, neurology, and neuroscience at the University of Cincinnati, who moderated the session.
“I think this serves as a model to recognize that many neurological disorders actually present with numerous psychiatric disorders,” Dr. Nasrallah said during the meeting, presented by MedscapeLive. MedscapeLive and this news organization are owned by the same parent company.

The hallmark of Parkinson’s disease is the accompanying motor symptoms, but the condition can bring other challenges. Among those are nonmotor symptoms, including depression, dementia, and even psychosis.
The culprit is Lewy bodies, which are also responsible for Lewy body dementia. “What we call Lewy body dementia and Parkinson’s disease are caused by the same pathological process – the formation of Lewy bodies in the brain,” Leslie Citrome, MD, MPH, said in an interview. Dr. Citrome discussed some of the psychiatric comorbidities associated with Parkinson’s disease at a virtual meeting presented by Current Psychiatry and the American Academy of Clinical Psychiatrists.
In fact, the association goes both ways. “Many people with Parkinson’s disease develop a dementia. Many people with Lewy body dementia develop motor symptoms that look just like Parkinson’s disease,” said Dr. Citrome, professor of psychiatry and behavioral sciences at New York Medical College, Valhalla, and president of the American Society for Clinical Psychopharmacology.
The motor symptoms of Parkinson’s disease are generally attributable to loss of striatal dopaminergic neurons, while nonmotor symptoms can be traced to loss of neurons in nondopaminergic regions. Nonmotor symptoms – often including sleep disorders, depression, cognitive changes, and psychosis – may occur before motor symptoms. Other problems may include autonomic dysfunction, such as constipation, sexual dysfunction, sweating, or urinary retention.
Patients might not be aware that nonmotor symptoms can occur with Parkinson’s disease and may not even consider mentioning mood changes or hallucinations to their neurologist. Family members may also be unaware.
Sleep problems are common in Parkinson’s disease, including rapid eye-movement sleep behavior disorders, vivid dreams, restless legs syndrome, insomnia, and daytime somnolence. Dopamine agonists may also cause unintended sleep.
Depression is extremely common, affecting up to 90% of Parkinson’s disease patients, and this may be related to dopaminergic losses. Antidepressant medications can worsen Parkinson’s disease symptoms: Tricyclic antidepressants increase risk of adverse events from anticholinergic drugs. Selective serotonin reuptake inhibitors (SSRIs) can exacerbate tremor and may increase risk of serotonin syndrome when combined with MAO‐B inhibitors.
Dr. Citrome was not aware of any antidepressant drugs that have been tested specifically in Parkinson’s disease patients, though “I’d be surprised if there wasn’t,” he said during the Q&A session. “There’s no one perfect antidepressant for people with depression associated with Parkinson’s disease.

FROM FOCUS ON NEUROPSYCHIATRY 2021
Progressive disability in MS explained?
Results from a retrospective study show that complete resolution of brain lesions on MRI was more common among patients with myelin-oligodendrocyte-glycoprotein-IgG-associated disorder (MOGAD). Complete resolution occurred in 72% of the group with MOGAD, versus 17% of those with MS and 14% of those with aquaporin-4-positive neuromyelitis optica spectrum disorder (AQP4+ NMOSD).
“What we found was, with MOGAD in particular, many of the lesions resolved completely,” said co-investigator Eoin Flanagan, MBBCh, neurologist, Mayo Clinic, Rochester, Minn. “That fits with MOGAD having a fairly good prognosis and patients not developing much long-term disability with that disease,” he said.
The researchers also studied whether scarring may account for the absence of slowly progressive disability among patients with AQP4+ NMOSD and MOGAD compared with patients with MS. “The differences in scarring that we found will help physicians distinguish these three diseases more easily to aid in diagnosis. More importantly, our findings improve our understanding of the mechanisms of nerve damage in these three diseases and may suggest an important role of such scars in the development of long-term disability in MS,” Dr. Flanagan said in a statement.
The findings were published online July 14 in Neurology.
Lesion evolution
MOGAD, AQP4+ NMOSD, and MS are inflammatory demyelinating disorders that share certain manifestations. However, these disorders differ in important ways, including the severity of attacks and their clinical course.
Although patients with MOGAD and AQP4+ NMOSD generally have severe attacks that bring major disability, the clinical course of these disorders is better than initial attacks would suggest. In contrast, patients with MS have comparatively mild attacks that are associated with a high risk for progressive disability.
Previous studies of these demyelinating disorders have examined the shape and location of lesions but not change over time. Observing these lesions’ development and resolution could provide information about disease course and influence treatment and the monitoring of disease activity, the current researchers noted.
They retrospectively identified consecutive patients with MOGAD, AQP4+ NMOSD, or MS who presented to the Mayo Clinic between January 2000 and August 2019. Data from a cohort of patients with MS in Olmsted County, Minn., were also included.
Eligible participants had experienced a first brain or myelitis attack, had undergone MRI of the brain or spinal cord within 6 weeks of the attack nadir, and had undergone a follow-up MRI 6 months after the attack.
Patients who experienced a relapse during follow-up in the same region as the initial attack were excluded. Concomitant brain and myelitis attacks were analyzed separately.
An index lesion was identified for each patient. The index lesion was defined as an acute lesion that provided an anatomic explanation for the clinical symptoms. If multiple lesions were present, the largest of them was chosen as the index lesion. MRIs were examined by neuroradiologists who were blinded to patients’ diagnoses and serology results.
Among the 156 participants, 67 had MS (76% women), 51 had AQP4+ NMOSD (80% women), and 38 had MOGAD (45% women). The median age at first attack for the groups was 37, 53, and 25 years, respectively.
In addition, 63 patients had relapsing-remitting MS, two had a single attack of progressive MS, and two had clinically isolated syndrome. No patients with NMOSD or MOGAD had developed progressive disease at final follow-up.
Participants experienced a total of 81 brain attacks and 91 myelitis attacks. Sixteen patients had experienced both a brain attack and a myelitis attack.
Symptoms corresponding to the index brain lesions were brainstem or cerebellar syndrome (56), encephalopathy or focal symptoms (12), or combinations of these (13). Among patients with an index myelitis attack, 31 had cervical involvement, 21 had thoracic involvement, and 39 had involvement of both regions.
Complete resolution
Results showed that 72% of patients with MOGAD experienced complete resolution of the brain index lesion, compared with 17% of patients with MS and 14% of patients with NMOSD (P < .001).
Similarly, 79% of the MOGAD group experienced complete resolution of the myelitis index lesion, compared with no members of the MS or NMOSD groups (P < .001 for both comparisons).
Complete resolution of all T2-abnormalities at MRI follow-up was more common in the MOGAD group than in the other two groups.
For brain attacks, complete resolution occurred in 39% of patients with MOGAD, 10% of patients with NMOSD, and 5% of patients with MS. For spinal cord attacks, complete resolution occurred in 79% of patients with MOGAD, versus none of the patients with NMOSD or MS.
Median reduction in T2 lesion area on follow-up axial brain MRI was larger in patients with MOGAD (213 mm2) than in those with NMOSD (104 mm2; P = .02) or MS (36 mm2; P < .001).
Reductions in lesion size on sagittal spine MRI follow-up were similar between the MOGAD (262 mm2) and NMOSD (309 mm2) groups; both experienced greater reductions than the MS group (23 mm2; P < .001).
Lesion prevention
Dr. Flanagan noted that the diagnosis of MOGAD is based on a test for MOG antibody, but sometimes false positive results occur. “A single follow-up MRI can be useful, showing that if all the lesions went away, you would be more confident that it would be MOGAD,” he said.
Study participants with MS experienced less lesion healing than the patients with MOGAD or NMOSD.
“We now have very effective medications in MS to prevent new lesions from occurring,” Dr. Flanagan said. The study highlights the importance of lesion prevention, “because when you do get a lesion, it does tend to stay and not recover completely,” he added.
He noted that the resolution of lesions in the study population may reflect remyelination. Future research examining whether remyelination is more efficient in MOGAD than in the other disorders could possibly lead to new approaches for MS treatment, said Dr. Flanagan.
“Maybe some of the MOGAD lesions are from edema. When we use steroids, that tends to resolve and not leave a scar. So, that’s another possibility. We’d like to better understand that,” he said.
Differences in pathology
Commenting on the findings, Bruce Cree, MD, PhD, professor of neurology, Weill Institute for Neurosciences, University of California, San Francisco, noted that the study is one of the first to systematically examine and compare MRI lesion evolution across three disease states.
“What they put their finger on are differences in the fundamental pathology of these three different diseases,” said Dr. Cree, who was not involved with the research.
The study’s cross-sectional comparison was its main strength, he noted.
“The main weakness, from my point of view, is that in these three disorders, optic nerve involvement is very common,” Dr. Cree said. “In this paper, no analysis of optic nerve lesions by MRI was performed.”
The researchers acknowledge this limitation and explain that they did not have consistent, dedicated orbital imaging for such an analysis.
Dr. Cree noted that the findings also provide a reminder that the pathogenesis of MOGAD is not yet clear.
“We know that these anti-MOG antibodies are associated with this demyelinating disorder, but whether these antibodies have a pathogenic role has yet to be clearly demonstrated,” said Dr. Cree. “What is actually going on within these lesions [is also] not fully understood.”
The finding that MOGAD lesions can resolve completely suggests that repair mechanisms are at work within the brain and spinal cord, he noted.
Being able to understand and comprehend what those mechanisms at work are and why they occur in MOGAD but not in NMOSD or MS “would be of enormous clinical advantage,” he said.
The current study also highlights the importance of incorporating imaging into clinical trials that study these rare disorders, especially serial imaging for MOGAD, Dr. Cree added.
This imaging is vital not only for developing new treatments but also for understanding the clinical impact of a given medication. “We really need rigorous imaging to be applied to these rare disorders, just as was done with MS,” Dr. Cree concluded.
The study was funded by the National Institute of Neurological Disorders and Stroke. Dr. Flanagan has received research support from MedImmune/Viela Bio. Dr. Cree is working with two of the researchers on the steering committee for the N-MOmentum trial of inebilizumab in patients with NMOSD. He has reported no relevant financial relationships.

“Maybe some of the MOGAD lesions are from edema. When we use steroids, that tends to resolve and not leave a scar. So, that’s another possibility. We’d like to better understand that,” he said.
Differences in pathology
Commenting on the findings, Bruce Cree, MD, PhD, professor of neurology, Weill Institute for Neurosciences, University of California, San Francisco, noted that the study is one of the first to systematically examine and compare MRI lesion evolution across three disease states.
“What they put their finger on are differences in the fundamental pathology of these three different diseases,” said Dr. Cree, who was not involved with the research.
The study’s cross-sectional comparison was its main strength, he noted.
“The main weakness, from my point of view, is that in these three disorders, optic nerve involvement is very common,” Dr. Cree said. “In this paper, no analysis of optic nerve lesions by MRI was performed.”
The researchers acknowledge this limitation and explain that they did not have consistent, dedicated orbital imaging for such an analysis.
Dr. Cree noted that the findings also provide a reminder that the pathogenesis of MOGAD is not yet clear.
“We know that these anti-MOG antibodies are associated with this demyelinating disorder, but whether these antibodies have a pathogenic role has yet to be clearly demonstrated,” said Dr. Cree. “What is actually going on within these lesions [is also] not fully understood.”
The finding that MOGAD lesions can resolve completely suggests that repair mechanisms are at work within the brain and spinal cord, he noted.
Being able to understand and comprehend what those mechanisms at work are and why they occur in MOGAD but not in NMOSD or MS “would be of enormous clinical advantage,” he said.
The current study also highlights the importance of incorporating imaging into clinical trials that study these rare disorders, especially serial imaging for MOGAD, Dr. Cree added.
This imaging is vital not only for developing new treatments but also for understanding the clinical impact of a given medication. “We really need rigorous imaging to be applied to these rare disorders, just as was done with MS,” Dr. Cree concluded.
The study was funded by the National Institute of Neurological Disorders and Stroke. Dr. Flanagan has received research support from MedImmune/Viela Bio. Dr. Cree is working with two of the researchers on the steering committee for the N-MOmentum trial of inebilizumab in patients with NMOSD. He has reported no relevant financial relationships.

A hot dog a day takes 36 minutes away
The death ‘dog’
Imagine you’re out in your backyard managing the grill for a big family barbecue. You’ve got a dazzling assortment of meat assorted on your fancy new propane grill, all charring nicely. Naturally, the hot dogs finish first, and as you pull them off, you figure you’ll help yourself to one now. After all, you are the chef, you deserve a reward. But, as you bite into your smoking hot sandwich, a cold, bony finger taps you on the shoulder. You turn and come face to face with the Grim Reaper. “YOU JUST LOST 36 MINUTES,” Death says. “ALSO, MAY I HAVE ONE OF THOSE? THEY LOOK DELICIOUS.”
Nonplussed and moving automatically, you scoop up another hot dog and place it in a bun. “WITH KETCHUP PLEASE,” Death says. “I NEVER CARED FOR MUSTARD.”
“I don’t understand,” you say. “Surely I won’t die at a family barbecue.”
“DO NOT CALL ME SHIRLEY,” Death says. “AND YOU WILL NOT. IT’S PART OF MY NEW CONTRACT.”
A new study, published in Nature Food, found that a person may lose up to 36 minutes for every hot dog consumed. Researchers from the University of Michigan analyzed nearly 6,000 different foods using a new nutritional index to quantify their health effects in minutes of healthy life lost or gained. Eating a serving of nuts adds an extra 26 minutes of life. The researchers determined that replacing just 10% of daily caloric intake from beef and processed foods with fruits, vegetables, and nuts can add 48 minutes per day. It would also reduce the daily carbon footprint by 33%.
“So you go around to everyone eating bad food and tell them how much life they’ve lost?” you ask when the Grim Reaper finishes his story. “Sounds like a drag.”
“IT IS. WE’VE HAD TO HIRE NEW BLOOD.” Death chuckles at its own bad pun. “NOW IF YOU’LL EXCUSE ME, I MUST CHASTISE A MAN IN FLORIDA FOR EATING A WELL-DONE STEAK.”
More stress, less sex
As the world becomes a more stressful place, the human population could face a 50% drop by the end of the century.
Think of stress as a one-two punch to the libido and human fertility. The more people are stressed out, the less likely they are to have quality interactions with others. Many of us would rather be alone with our wine and cheese to watch our favorite show.
Researchers have found that high stress levels have been known to drop sperm count, ovulation, and sexual activity. Guess what? There has been a 50% decrease in sperm counts over the last 50 years. That’s the second punch. But let’s not forget, the times are changing.
“Changes in reproductive behavior that contribute to the population drop include more young couples choosing to be ‘child-free,’ people having fewer children, and couples waiting longer to start families,” said Alexander Suvorov, PhD, of the University of Massachusetts, the paper’s author.
Let’s summarize: The more stress we’re dealing with, the less people want to deal with each other.
Who would have thought the future would be less fun?
‘You are not a horse. You are not a cow. Seriously, y’all. Stop it.’
WARNING: The following descriptions of COVID-19–related insanity may be offensive to some readers.
Greetings, ladies and gentlemen! Welcome to the first round of Pandemic Pandemonium. Let’s get right to the action.
This week’s preshow match-off involves face mask woes. The first comes to us from Alabama, where a woman wore a space helmet to a school board meeting to protest mask mandates. The second comes from Australia, in the form of mischievous magpies. We will explain.
It is not uncommon for magpies to attack those who come too close to their nests in the spring, or “swooping season,” as it’s affectionately called. The magpies are smart enough to recognize the faces of people they see regularly and not attack; however, it’s feared that mask wearing will change this.
While you’re chewing on that exciting appetizer, let’s take a look at our main course, which has a distinct governmental flavor. Jeff Landry is the attorney general of Louisiana, and, like our space-helmet wearer, he’s not a fan of mask mandates. According to Business Insider, Mr. Landry “drafted and distributed sample letters intended to help parents evade mask-wearing ordinances and COVID-19 vaccination requirements for their children in schools.”
Up against him is the Food and Drug Administration’s Twitter account. In an unrelated matter, the agency tweeted, “You are not a horse. You are not a cow. Seriously, y’all. Stop it.” This was in response to people using the nonhuman forms of ivermectin to treat very human COVID-19.
Well, there you have it. Who will win tonight’s exciting edition of Pandemic Pandemonium? The first reader to contact us gets to decide the fate of these worthy contestants.
From venomous poison to heart drug
It’s not likely that anyone who sees a giant, venomous spider is thinking, “Hey! That thing could save my life!” It’s usually quite the opposite. Honestly, we would run away from just about any spider. But what if one of the deadliest spiders in the world could also save you from dying of a heart attack?
You probably don’t believe us, right? That’s fair, but the deadly Fraser Island (K’gari) funnel web spider, might also be the most helpful. Investigators from the University of Queensland in Australia have found a way to extract a molecule from the spider’s venom that might help stop damage from heart attacks and may even preserve hearts being used for transplants. “The Hi1a protein from spider venom blocks acid-sensing ion channels in the heart, so the death message is blocked, cell death is reduced, and we see improved heart cell survival,” Nathan Palpant, PhD, of the university, noted in a written statement.
No one has ever developed a drug to stop the “death signal,” so maybe it’s time to befriend spiders instead of running away from them in horror. Just leave the venom extraction to the professionals.

Young Black and White athletes differ in how they recover from concussions
, according to a new study on racial differences in concussion recovery.
“The findings from this study provide novel evidence that the recovery experience following sport-related concussion likely differs between Black and White athletes, and understanding these differences may serve to provide better and more personalized intervention and management strategies,” wrote lead author Aaron M. Yengo-Kahn, MD, of Vanderbilt University Medical Center in Nashville, Tenn. The study was published in the Journal of Neurosurgery: Pediatrics.
To assess how postconcussion experiences and recovery time differ among young White and Black athletes, the researchers launched a retrospective cohort study of youths between the ages of 12 and 23 from the middle Tennessee, northern Alabama, and southern Kentucky regions who had been treated for sport-related concussion. Using data from the Vanderbilt Sports Concussion Center’s outcome registry, they examined the records of 247 student-athletes, 211 of whom were White and 36 of whom were Black.
The majority of the athletes were male – 58% of the White group and 78% of the Black group – and their average age across groups was roughly 16 years. Thirty-three percent of the Black athletes were on public insurance, compared with just 6% of the White athletes, and 41% of the Black athletes lived in low–median income areas while 55% of the White athletes lived in areas with a high median income. Approximately 90% of each group played contact sports.
The median time to symptom resolution was 21 days (interquartile range, 10.5-61.0) for White athletes but just 12.3 days (IQR, 6.8-28.0) for Black athletes. Multivariable regression confirmed that Black athletes reached asymptomatic status sooner than White athletes (hazard ratio, 1.497; 95% confidence interval, 1.014-2.209; P = .042). “The observed shorter symptom resolution among the Black athletes may be explained by a complex interplay among race, concussion knowledge, attitudes toward sport-related concussion, reporting behavior, and sociodemographic disparities,” the authors noted.
The median time until returning to school post injury was 2 school days (IQR, 0-5) for White athletes and 0 school days (IQR, 0-2) for Black athletes. After multivariable analysis, being Black was indeed associated with returning to school sooner, compared with being White (HR, 1.522; 95% CI, 1.02-2,27; P = .040). Being Black was also associated with being less likely to a report a change in daily activity post concussion (odds ratio, 0.368; 95% CI, 0.136-0.996; P = .049).
Adding race to research
To make headway toward understanding race’s impact on concussion research, the authors proposed three immediate steps: Work directly with schools instead of clinics or emergency departments, match the diversity of study cohorts with the racial makeup of the surrounding community, and consider race as a covariate during study design.
“In our work with concussions, there is very little reported on race or racism or how racism affects how patients are navigating these spaces,” said coauthor Jessica Wallace, PhD, of the department of health science at the University of Alabama in Tuscaloosa, Ala., in an interview. “But we have so many athletes at the youth level, adolescent level, even the collegiate level; it’s such a diverse array of patients. We need to have data representative of all of our groups so that we know where we need to be intentional about reducing disparities and closing gaps.”
Dr. Wallace, who recently authored a study on the underreporting of concussions among Black and White high school athletes, emphasized the need for concussion research to be a true collaboration across disciplines.
“I approach this work from this public health and athletic training lens, whereas a lot of my collaborators are in neurosurgery and neurology,” she said. “Moving forward, we as a scientific clinical community have to do interdisciplinary work and be very intentional about how we go about closing these gaps. We have to recognize that there are differences in knowledge and in care, and they’re unacceptable, and we have to work collaboratively in providing resources to communities equitably to decrease them.”
The authors acknowledged their study’s limitations, including the retrospective nature of the study, using zip codes to determine median household income, and an unbalanced number of White and Black athletes. They did add, however, that the ratio of participants “generally aligns with census data in the surrounding metropolitan and county areas.” That said, they also surmised that the scarcity of Black athletes could indicate a deeper disparity in health care system usage and asked future researchers to “consider enrolling athletes directly from schools rather than from within the concussion clinic only.”
Dr. Yengo-Kahn disclosed holding a compensated position on the scientific advisory board of BlinkTBI, but the authors noted that the company had no role in the study and its products were not used. No other conflicts of interest were reported.

They did add, however, that the ratio of participants “generally aligns with census data in the surrounding metropolitan and county areas.” That said, they also surmised that the scarcity of Black athletes could indicate a deeper disparity in health care system usage and asked future researchers to “consider enrolling athletes directly from schools rather than from within the concussion clinic only.”
Dr. Yengo-Kahn disclosed holding a compensated position on the scientific advisory board of BlinkTBI, but the authors noted that the company had no role in the study and its products were not used. No other conflicts of interest were reported.

Atogepant reduces migraine days: ADVANCE trial results published
full results from a phase 3 trial suggest.
AbbVie, the company developing the oral therapy, announced topline results of the ADVANCE trial of atogepant last year. Safety results were presented in April at the 2021 annual meeting of the American Academy of Neurology.
The full results were published online Aug. 19 in the New England Journal of Medicine ahead of the upcoming target action date of the U.S. Food and Drug Administration.
The multicenter study included nearly 900 patients who were randomly assigned to receive either placebo or one of three doses of atogepant for 12 weeks. The mean number of monthly migraine days decreased by about 4 for all three doses of the active treatment, compared with a reduction of 2.5 days with placebo.
“Overall, this study showed us that atogepant was safe and surprisingly seems to be pretty effective regardless of the dose,” said lead author Jessica Ailani, MD, director of MedStar Georgetown Headache Center and associate professor of neurology at Georgetown University, Washington.
All doses effective
The study included 873 patients with episodic migraine with or without aura. Patients who were not assigned to the placebo control group received either 10 mg, 30 mg, or 60 mg of atogepant once daily.
After a 4-week screening period, all patients received treatment for 12 weeks and then entered a 4-week safety follow-up period. In total, the participants completed eight scheduled clinical visits.
The mean reduction from baseline in the mean number of migraine days per month was 3.7 with the 10-mg dose of atogepant, 3.9 with the 30-mg dose, 4.2 with the 60-mg dose, and 2.5 with placebo. The differences between each active dose and placebo was statistically significant (P < .001).
Treatment with the CGRP inhibitor was also associated with a reduction in the mean number of headache days per month. The mean reduction from baseline was 3.9 days for the 10-mg dose, 4.0 days for the 30-mg dose, 4.2 days for the 60-mg dose, and 2.5 days for placebo (P < .001 for all comparisons with placebo).
In addition, for 55.6% of the 10-mg group, 58.7% of the 30-mg group, 60.8% of the 60-mg group, and 29.0% of the control group, there was a reduction of at least 50% in the 3-month average number of migraine days per month (P < .001 for each vs. placebo).
The most commonly reported adverse events (AEs) among patients who received atogepant were constipation (6.9%-7.7% across doses), nausea (4.4%-6.1%), and upper respiratory tract infection (1.4%-3.9%). Frequency of AEs did not differ between the active-treatment groups and the control group, and no relationships between AEs and atogepant dose were observed.
Multidose flexibility
“Side effects were pretty even across the board,” said Dr. Ailani. She noted that the reported AEs were expected because of atogepant’s mechanism of action. In addition, the rate of discontinuation in the study was low.
The proportion of participants who experienced a reduction in monthly migraine days of at least 50% grew as time passed. “By the end of this study, your chance of having a greater than 50% response is about 75%,” Dr. Ailani said.
“Imagine telling your patient, ‘You stick on this drug for 3 months, and I can almost guarantee you that you’re going to get better,’” she added.
Although the treatment has no drug-drug contraindications, drug-drug interactions may occur. “The availability of various doses would allow clinicians to adjust treatment to avoid potential drug-drug interactions,” said Dr. Ailani. “That multidose flexibility is very important.”
An FDA decision on atogepant could be made in the coming months. “I’m hopeful, as a clinician, that it is positive news, because we really have waited a long time for something like this,” Dr. Ailani said.
“You can easily identify patients who would do well on this medication,” she added.
In a different study of atogepant among patients with chronic migraine, there were recruitment delays because of the pandemic. That study is now almost complete, Dr. Ailani reported.
“Well-conducted study”
Commenting on the findings, Kathleen B. Digre, MD, chief of the division of headache and neuro-ophthalmology at the University of Utah Health, Salt Lake City, expressed enthusiasm for the experimental drug. “I’m excited to see another treatment modality for migraine,” said Dr. Digre, who was not involved with the research. “It was a very well-conducted study,” she added.
The treatment arms were almost identical in regard to disease severity, and all the doses showed an effect. Although the difference in reduction of monthly migraine days in comparison with placebo was numerically small, “for people who have frequent migraine, it’s important,” Dr. Digre said.
The results for atogepant should be viewed in a larger context, however. “Even though it’s a treatment that works better than placebo for well-matched controls, it may not be a medication that everybody’s going to respond to,” she noted. “And we can’t generalize it for some of the most disabled people, which is for chronic migraine,” she said.
It is significant that the study was published in the New England Journal of Medicine, Dr. Digre noted. “Sometimes migraine is dismissed as not important and not affecting people’s lives,” she said. “That makes me very happy to see migraine being taken seriously by our major journals.”
In addition, she noted that the prospects for FDA approval of atogepant seem favorable. “I’m hopeful that they will approve it, because it’s got a low side-effect profile, plus it’s effective.”
Migraine-specific preventive therapy has emerged only in the past few years. “I’m so excited to see this surge of preventive medicine for migraine,” Dr. Digre said. “It’s so important, because we see so many people who are disabled by migraine,” she added.
The study was funded by Allergan before atogepant was acquired by AbbVie. Dr. Ailani has received honoraria from AbbVie for consulting, has received compensation from Allergan and AbbVie for participating in a speakers’ bureau, and has received clinical trial grants from Allergan. Dr. Digre has reported no relevant financial relationships.

New recommendations address ME/CFS diagnosis and management
New consensus recommendations address diagnosis and management of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), with advice that may also be helpful for patients with lingering symptoms following acute COVID-19 infection.
The document was published online Aug. 25, 2021, in the Mayo Clinic Proceedings by the 23-member U.S. ME/CFS Clinician Coalition, headed by Lucinda Bateman, MD, of the Bateman Horne Center of Excellence, Salt Lake City. The document is the culmination of work that began with a summit held at the center in March 2018.
The target audience is both generalist and specialist health care providers. While ME/CFS is estimated to affect up to 2.5 million Americans, more than 90% are either undiagnosed or misdiagnosed with other conditions such as depression. And those who are diagnosed often receive inappropriate, outdated treatments such as psychotherapy and exercise prescriptions.
“Despite myalgic encephalomyelitis/chronic fatigue syndrome affecting millions of people worldwide, many clinicians lack the knowledge to appropriately diagnose or manage ME/CFS. Unfortunately, clinical guidance has been scarce, obsolete, or potentially harmful,” Dr. Bateman and colleagues wrote.
The urgency of appropriate recognition and management of ME/CFS has increased as growing numbers of people are exhibiting signs and symptoms of ME/CFS following acute COVID-19 infection. This isn’t surprising because the illness has long been linked to other infections, including Epstein-Barr virus, the authors noted.
The document covers the epidemiology, impact, and prognosis of ME/CFS, as well as etiology and pathophysiology. “Scientific studies demonstrate multiple dysfunctional organ systems, including neuro, immune, and metabolic, in ME/CFS. These findings are not explained merely by deconditioning,” document coauthor Lily Chu, MD, an independent consultant in Burlingame, Calif., said in an interview.
The document reviews the 2015 U.S. Institute of Medicine (now Academy of Medicine) diagnostic criteria that are now also recommended by the Centers for Disease Control and Prevention. They are based on four main symptoms: substantial reduction or impairment in the ability to engage in preillness levels of occupational, educational, social or personal activities for longer than 6 months; postexertional malaise, a worsening of all current symptoms, that patients often describe as a “crash”; unrefreshing sleep; and cognitive impairment and/or orthostatic intolerance.
“The new diagnostic criteria focusing on the key symptom of postexertional malaise rather than chronic fatigue, which is common in many conditions, may make the diagnostic process quicker and more accurate. Diagnosis now is both an inclusionary and not just exclusionary process, so it’s not necessary to eliminate all causes of fatigue. Diagnose patients who fit the criteria and be alert for it in people with persistent symptoms post COVID,” Dr. Chu said.
The document provides advice for taking a clinical history to obtain the information necessary for making the diagnosis, including use of laboratory testing to rule out other conditions. Physical exams, while they may not reveal specific abnormalities, may help in identifying comorbidities and ruling out alternative diagnoses.
A long list of nonpharmacologic and pharmacologic treatment and management approaches is offered for each of the individual core and common ME/CFS symptoms, including postexertional malaise, orthostatic intolerance, sleep issues, cognitive dysfunction and fatigue, immune dysfunction, pain, and gastrointestinal issues.
The document recommends against using the “outdated standard of care” cognitive-behavioral therapy and graded exercise therapy as primary treatments for the illness. Instead, the authors recommend teaching patients “pacing,” an individualized approach to energy conservation aimed at minimizing the frequency, duration, and severity of postexertional malaise.
Clinicians are also advised to assess patients’ daily living needs and provide support, including acquiring handicap placards, work or school accommodations, and disability benefits.
“There are things clinicians can do now to help patients even without a disease-modifying treatment. These are actions they are already familiar with and carry out for people with other chronic diseases, which often have limited treatment options as well. Don’t underestimate the importance and value of supportive care for patients.” Dr. Chu said.
The recommendations are based primarily on clinical expertise because there are very few randomized trials, and much of the evidence from other types of trials has been flawed, document coauthor Anthony L. Komaroff, MD, of Brigham and Women’s Hospital and Harvard Medical School, both in Boston, said in an interview.
“The sad reality is there aren’t very many large randomized clinical trials with this illness and so what a group of very experienced clinicians did was to gather their collective experience and report it as that. It’s largely uncontrolled experience, but from people who have seen a lot of patients, for what it’s worth to the medical community.”
Dr. Komaroff also advised that clinicians watch out for ME/CFS in patients with long COVID. “If we find that those called long COVID meet ME/CFS criteria, the reason for knowing that is that there are already some treatments that according to experienced clinicians are helpful for ME/CFS, and it would be perfectly appropriate to try some of them in long COVID, particularly the ones that have minimal adverse reactions.”
The guidelines project was supported by the Open Medicine Foundation. Dr. Komaroff reported receiving personal fees from Serimmune outside the submitted work. Dr. Chu has no disclosures.

Dr. Komaroff also advised that clinicians watch out for ME/CFS in patients with long COVID. “If we find that those called long COVID meet ME/CFS criteria, the reason for knowing that is that there are already some treatments that according to experienced clinicians are helpful for ME/CFS, and it would be perfectly appropriate to try some of them in long COVID, particularly the ones that have minimal adverse reactions.”

Anxiety, inactivity linked to cognitive impairment in Parkinson’s
Parkinson’s disease patients who develop anxiety early in their disease are at risk for reduced physical activity, which promotes further anxiety and cognitive decline, data from nearly 500 individuals show.
Anxiety occurs in 20%-60% of Parkinson’s disease (PD) patients but often goes undiagnosed, wrote Jacob D. Jones, PhD, of California State University, San Bernardino, and colleagues.
“Anxiety can attenuate motivation to engage in physical activity leading to more anxiety and other negative cognitive outcomes,” although physical activity has been shown to improve cognitive function in PD patients, they said. However, physical activity as a mediator between anxiety and cognitive function in PD has not been well studied, they noted.
In a study published in Mental Health and Physical Activity Participants were followed for up to 5 years and completed neuropsychological tests, tests of motor severity, and self-reports on anxiety and physical activity. Anxiety was assessed using the State-Trait Anxiety Inventory-Trait (STAI-T) subscale. Physical activity was assessed using the Physical Activity Scale for the Elderly (PASE). Motor severity was assessed using the Unified Parkinson’s Disease Rating Scale-Part III (UPDRS). The average age of the participants was 61 years, 65% were men, and 96% were White.
Using a direct-effect model, the researchers found that individuals whose anxiety increased during the study period also showed signs of cognitive decline. A significant between-person effect showed that individuals who were generally more anxious also scored lower on cognitive tests over the 5-year study period.
In a mediation model computed with structural equation modeling, physical activity mediated the link between anxiety and cognition, most notably household activity.
“There was a significant within-person association between anxiety and household activities, meaning that individuals who became more anxious over the 5-year study also became less active in the home,” reported Dr. Jones and colleagues.
However, no significant indirect effect was noted regarding the between-person findings of the impact of physical activity on anxiety and cognitive decline. Although more severe anxiety was associated with less activity, cognitive performance was not associated with either type of physical activity.
The presence of a within-person effect “suggests that reductions in physical activity, specifically within the first 5 years of disease onset, may be detrimental to mental health,” the researchers emphasized. Given that the study population was newly diagnosed with PD “it is likely the within-person terms are more sensitive to changes in anxiety, physical activity, and cognition that are more directly the result of the PD process, as opposed to lifestyle/preexisting traits,” they said.
The study findings were limited by several factors, including the use of self-reports to measure physical activity, and the lack of granular information about the details of physical activity, the researchers noted. Another limitation was the inclusion of only newly diagnosed PD patients, which might limit generalizability.
“Future research is warranted to understand if other modes, intensities, or complexities of physical activity impact individuals with PD in a different manner in relation to cognition,” they said.

AHA targets rising prevalence of obstructive sleep apnea in children
Obstructive sleep apnea is becoming more common in children and adolescents as the prevalence of obesity increases, but it may also be a preventable risk factor for cardiovascular disease, according to a new scientific statement from the American Heart Association.
The statement focuses on the links between OSA and CVD risk factors in children and adolescents, and reviews diagnostic strategies and treatments. The writing committee reported that 1%-6% of children and adolescents have OSA, as do up to 60% of adolescents considered obese.
The statement was created by the AHA’s Atherosclerosis, Hypertension, and Obesity in the Young subcommittee of the Council on Cardiovascular Disease in the Young and was published online in the Journal of the American Heart Association.
Carissa M. Baker-Smith, MD, chair of the writing group chair and director of pediatric preventive cardiology at Nemours Cardiac Center, Alfred I. duPont Hospital for Children, Wilmington, Del., explained the rationale for issuing the statement at this time, noting that the relationship between OSA and CVD in adults is well documented.
“There has been less focus on the importance of recognizing and treating sleep apnea in youth,” she said in an interview. “Thus, we felt that it was vitally important to get the word out to parents and to providers that paying attention to the quality and duration of your child’s sleep is vitally important to a child’s long-term heart health. Risk factors for heart disease, when present in childhood, can persist into adulthood.”
Clarity on polysomnography
For making the diagnosis of OSA in children, the statement provides clarity on the use of polysomnography and the role of the apnea-hypopnea index, which is lower in children with OSA than in adults. “One controversy, or at least as I saw it, was whether or not polysomnography testing is always required to make the diagnosis of OSA and before proceeding with tonsil and adenoid removal among children for whom enlarged tonsils and adenoids are present,” Dr. Baker-Smith said. “Polysomnography testing is not always needed before an ear, nose, and throat surgeon may recommend surgery.”
The statement also noted that history and physical examination may not yield enough reliable information to distinguish OSA from snoring.
In areas where sleep laboratories that work with children aren’t available, alternative tests such as daytime nap polysomnography, nocturnal oximetry, and nocturnal video recording may be used – with a caveat. “These alternative tests have weaker positive and negative predictive values when compared with polysomnography,” the writing committee noted. Home sleep apnea tests aren’t recommended in children. Questionnaires “are useful as screening, but not as diagnostic tools.”
Pediatric patients being evaluated for OSA should also be screened for hypertension and metabolic syndrome, as well as central nervous system and behavioral disorders. Diagnosing OSA in children and adolescents requires “a high index of suspicion,” the committee wrote.
Pediatricians and pediatric cardiologists should exercise that high index of suspicion when receiving referrals for cardiac evaluations for attention deficit hyperactivity disorder medication, Dr. Baker-Smith said. “Take the time to ask about a child’s sleep – snoring, apnea, etc. – especially if the child has obesity, difficulty focusing during the day, and if there is evidence of systemic hypertension or other signs of metabolic syndrome,” she said.
Risk factors for OSA in children
The statement also reviewed risk factors for OSA, among them obesity, particularly among children younger than 6 years. Other risk factors include upper and lower airway disease, hypotonia, parental history of hyperplasia of the adenoids and tonsils, craniofacial malformations, and neuromuscular disorders. However, the committee cited “limited data” to support that children with congenital heart disease may be at greater risk for OSA and sleep-disordered breathing (SDB).
Black children are at significantly greater risk, and socioeconomic factors “may be potential confounders,” the committee stated. Other risk factors include allergic rhinitis and sickle cell disease.
But the statement underscores that “obesity is the main risk factor” for OSA in children and adolescents, and that the presence of increased inflammation may explain this relationship. Steroids may alleviate these symptoms, even in nonobese children, and removal of the adenoids or tonsils is an option to reduce inflammation in children with OSA.
“Obesity is a significant risk factor for sleep disturbances and obstructive sleep apnea, and the severity of sleep apnea may be improved by weight-loss interventions, which then improves metabolic syndrome factors such as insulin sensitivity,” Dr. Baker-Smith said. “We need to increase awareness about how the rising prevalence of obesity may be impacting sleep quality in kids and recognize sleep-disordered breathing as something that could contribute to risks for hypertension and later cardiovascular disease.”
Children in whom OSA is suspected should also undergo screening for metabolic syndrome, and central nervous system and behavioral disorders.
Cardiovascular risks
The statement explores the connection between cardiovascular complications and SDB and OSA in depth.
“Inadequate sleep duration of < 5 hours per night in children and adolescents has been linked to an increased risk of hypertension and is also associated with an increased prevalence of obesity,” the committee wrote.
However, the statement left one question hanging: whether OSA alone or obesity cause higher BP in younger patients with OSA. But the committee concluded that BP levels increase with the severity of OSA, although the effects can vary with age. OSA in children peaks between ages 2 and 8, corresponding to the peak prevalence of hypertrophy of the tonsils and adenoids. Children aged 10-11 with more severe OSA may have BP dysregulation, while older adolescents develop higher sustained BP. Obesity may be a confounder for daytime BP elevations, while nighttime hypertension depends less on obesity and more on OSA severity.
“OSA is associated with abnormal BP in youth and, in particular, higher nighttime blood pressures and loss of the normal decline in BP that should occur during sleep,” Dr. Baker-Smith said. “Children with OSA appear to have higher BP than controls during both sleep and wake times, and BP levels increase with increasing severity of OSA.”
Nonetheless, children with OSA are at greater risk for other cardiovascular problems. Left ventricular hypertrophy may be a secondary outcome. “The presence of obstructive sleep apnea in children is associated with an 11-fold increased risk for LVH in children, a relationship not seen in the presence of primary snoring alone,” Dr. Baker-Smith said.
