Four common motor abnormalities in schizophrenia patients were associated with at least one poor functional outcome, based on data from 156 individuals.

Approximately half of adults with schizophrenia suffer from motor abnormalities that may impair their ability to work and decrease their quality of life, wrote Niluja Nadesalingam, MD, of the University of Bern, Switzerland, and colleagues. “Although previous reports show strong associations between single movement abnormalities and global as well as social functioning, we still struggle to understand the contribution of various motor domains,” they said.

The impact of these abnormalities on social and global functioning and on functional capacity remains unclear, but the researchers proposed that motor abnormalities would be associated with worse functional outcomes in schizophrenia patients.

In a study published in Comprehensive Psychiatry, the researchers identified patients with diagnosed schizophrenia spectrum disorders who were treated on an inpatient or outpatient basis at a single center. They collected data on five motor abnormalities: parkinsonism, catatonia, dyskinesia, neurological soft signs (NSS), and psychomotor slowing (PS). They assessed functional outcomes using the Global Assessment of Functioning (GAF), the Social and Occupational Functioning Assessment Scale (SOFAS), and the UCSD Performance-Based Skills Assessment (UPSA-B). The average age of the participants was 37.9 years and 88 of the 156 were male. The average duration of illness was 12.5 years.

Overall, patients with catatonia and parkinsonism scored significantly lower on GAF and SOFAS scale compared to those without catatonia and parkinsonism (P < .035 and P < .027, respectively).

No significant differences in functional outcomes appeared between patients with and without dyskinesia.

However, significant negative correlations were identified for parkinsonism and PS with GAF, SOFAS, and UPSA-B (P < .036 for all). “Our study further found that parkinsonism and psychomotor slowing also impair the functional capacity of patients,” which may be influenced by factors including deficits in social interaction and cognitive impairment, the researchers said.

Overall, the study findings demonstrate that motor abnormalities in patients with schizophrenia are strongly associated with poor functional outcomes, and the stronger the motor impairment, the worse the global and social functioning, the researchers said.

As for potential pathways, “motor abnormalities are readily observable signs, allowing laypersons to perceive subjects with schizophrenia as somebody with severe mental illness. Thus, motor abnormalities might lead to stigmatization of patients suffering from schizophrenia,” they wrote in their discussion.

The researchers emphasized the need to explore alternative treatment options that might improve motor abnormalities, such as transcranial magnetic stimulation, given the potential of antipsychotic medications to introduce additional motor abnormalities.

The study findings were limited by several factors including the potential for missed confounding variables, the small number of patients with dyskinesia, and the inability to deduce the course of illness because most of the patients were in psychotic episodes, the researchers noted.

However, the results suggest that specific motor abnormalities are associated with poor global and social functioning, and with reduced functional capacity, in adults with schizophrenia, the researchers said. “Future studies need to test whether amelioration of motor abnormalities may improve community functioning,” they concluded.

The study was supported by the Swiss National Science Foundation, the Bangerter Rhyner Foundation, and the Adrian and Simone Frutiger Foundation. Lead author Dr. Nadesalingam had no financial conflicts to disclose.

Deaf babies and toddlers with developmental delays may benefit significantly from receiving cochlear implants over hearing aids.

A new study, published in the journal Pediatrics, pushes against the notion that children with low nonverbal cognition and adaptive functioning skills won’t improve if given cochlear implants. Some insurers cover hearing aids for children with developmental disorders but not the implants, which can cost between $60,000 and $100,000 per ear.

“We were surprised [by] the large magnitude of the improvements, not only in quality of life, but also in cognition, ability to function in daily living situations, and speech and language,” lead author John S. Oghalai, MD, of the University of Southern California, Los Angeles, told this news organization. “Remember, these are children with substantial developmental delays. Any improvements are incredibly important and meaningful.”

All children with severe hearing loss should be referred for cochlear implant evaluation, “regardless of the presence of other disabilities,” Dr. Oghalai said. “The younger this referral happens, the better the outcomes will be.”

Dr. Oghalai and his colleagues reviewed data from 204 children approximately 1-3 years old with hearing aids receiving treatment in Texas and California. Of these, 138 received a cochlear implant and had normal cognitive skills and social competence (referred to as adaptive behavior). Another 37 received a cochlear implant and also met criteria for early developmental impairment (EDI), defined by measures of nonverbal cognitive scores and adaptive functioning.

A third group of 29 children with EDI continued with hearing aids without a cochlear implant.

The children were evaluated annually for 1-5 years, with the average follow-up of 2 years. At baseline, no significant differences were noted between the children with EDI who received implants and those who did not on cognition, language, auditory skills, or measures of parental or child stress.

Overall, children who received implants scored higher on cognitive and social measures than those who continued using hearing aids.

Compared with children with EDI who received implants, children without EDI who received implants had significantly higher developmental scores by the study’s end (P ≤ .001), whereas children with EDI who did not receive implants had significantly lower scores (P ≤ .04).

Children who received implants, and their parents, also experienced less stress than those who did not receive the devices, according to the researchers.

Dr. Oghalai and colleagues also measured developmental trajectories for each cohort. Children without delays who received implants had the best outcomes, but those with EDI who received implants had better outcomes than those with EDI and hearing aids.
 

Findings ‘overdue’

“This study is overdue,” Howard Francis, MD, chair of the department of head and neck surgery & communication sciences at Duke University, Durham, N.C., told this news organization.

Dr. Francis called the new research “reasonably powered and designed,” and said it “documents benefits in the cognitive, language, and patient-child relationship domains” in children who received cochlear implants “compared to children with similar levels of developmental delay whose hearing loss was treated using hearing aids.”  

However, “larger studies will be needed to account for potential effects of older age at intervention in the hearing aid group,” he said. Socioeconomic effects are a topic for future research as well, Dr. Francis added.

The researchers initially wanted to perform a controlled clinical trial. However, by the time they secured funding, health insurance policy had changed to cover cochlear implants for children without EDI because of demonstrated benefits shown in studies.

They also were unable to determine the reasons for families’ decisions to choose implants or hearing aids and were unable to assess the impact of insurance on the choice of implantation. But they did find that families with insurers who would cover implants often did choose the devices. Children were also followed for an average of 2 years, so long-term outcomes are unknown.  

Despite these limitations, the results support the value of cochlear implantation in children with disabilities and developmental delays, and it should be discussed with parents, the researchers concluded.

“Cochlear implants are just a tool; they do not provide speech and language,” Dr. Oghalai said. “Any child with severe hearing loss requires significant therapy and education via sign language, auditory-verbal therapy, or both. Making the decision about what type of therapy to do is personal, and it depends upon the family and the options that are available to them in their community.”

The study was funded by the National Institutes of Health. The researchers and Dr. Francis have disclosed no relevant financial relationships.

Spending more time doing light-intensity activities and less time being sedentary was associated with a reduced risk for first stroke in a population-based study of middle aged and older adults.

The study also found relatively short periods of moderate to vigorous exercise were associated with reduced stroke risk.

“Our results suggest there are a number of ways to reduce stroke risk simply by moving about,” said lead author Steven P. Hooker, PhD, San Diego State University. “This could be with short periods of moderate to vigorous activity each day, longer periods of light activity, or just sedentary for shorter periods of time. All these things can make a difference.”

Dr. Hooker explained that, while it has been found previously that moderate to vigorous exercise reduces stroke risk, this study gives more information on light-intensity activities and sedentary behavior and the risk of stroke.

“Our results suggest that you don’t have to be a chronic exerciser to reduce stroke risk. Replacing sedentary time with light-intensity activity will be beneficial. Just go for a short walk, get up from your desk and move around the house at regular intervals. That can help to reduce stroke risk,” Dr. Hooker said.  

“Our message is basically to sit less and move more,” he added.  

The study was published online in JAMA Network Open.

The study involved 7,607 U.S. individuals without a history of stroke, with oversampling from the southeastern “Stroke Belt,” who were participating in the REGARDS cohort study.

The participants wore an accelerometer to measure physical activity and sedentary behavior for 7 consecutive days. The mean age of the individuals was 63 years; 54% were female, 32% were Black.

Over a mean follow-up of 7.4 years, 286 incident stroke cases occurred.

Results showed that increased levels of physical activity were associated with reduced risk of stroke.

For moderate to vigorous activity, compared with participants in the lowest tertile, those in the highest tertile of total daily time in moderate to vigorous activity had a 43% lower risk of stroke.

In the current study, the amount of moderate to vigorous activity associated with a significant reduction in stroke risk was approximately 25 minutes per day (3 hours per week).

Dr. Hooker noted that moderate to vigorous activity included things such as brisk walking, jogging, bike riding, swimming, or playing tennis or soccer. “Doing such activities for just 25 minutes per day reduced risk of stroke by 43%. This is very doable. Just commuting to work by bicycle would cover you here,” he said.

In terms of light-intensity activity, individuals who did 4-5 hours of light activities each day had a 26% reduced risk for first stroke, compared with those doing less than 3 hours of such light activities.

Dr. Hooker explained that examples of light activity included household chores, such as vacuuming, washing dishes, or going for a gentle stroll. “These activities do not require heaving breathing, increased heart rate or breaking into a sweat. They are activities of daily living and relatively easy to engage in.”

But he pointed out that the 4-5 hours of light activity every day linked to a reduction in stroke risk may be more difficult to achieve than the 25 minutes of moderate to vigorous activity, saying: “You have to have some intentionality here.”
 

Long bouts of sedentary time are harmful

The study also showed that sedentary time was associated with a higher risk for stroke.

The authors noted that time spent in sedentary behavior is of interest because most adults spend most of their awake time being physically inactive.

They report that participants in the highest tertile of sedentary time (more than 13 hours/day) exhibited a 44% increase in risk of stroke, compared with those in the lowest tertile (less than 11 hours/day), and the association remained significant when adjusted for several covariates, including moderate to vigorous activity.

“Even when controlling for the amount of other physical activity, sedentary behavior is still highly associated with risk of stroke. So even if you are active, long bouts of sedentary behavior are harmful,” Dr. Hooker commented.

They also found that longer bouts of sedentary time (more than 17 minutes at a time) were associated with a 54% higher risk of stroke than shorter bouts (less than 8 minutes).

“This suggests that breaking up periods of sedentary behavior into shorter bouts would be beneficial,” Dr. Hooker said.

“If you are going to spend the evening on the couch watching television, try to stand up and walk around every few minutes. Same for if you are sitting at a computer all day – try having a standing workstation, or at least take regular breaks to walk around,” he added.

This research was supported by grants from the National Institute of Neurological Disorders and Stroke and the National Institute on Aging. Additional funding was provided by an unrestricted grant from the Coca-Cola Company. The authors report no disclosures.

The authors noted that time spent in sedentary behavior is of interest because most adults spend most of their awake time being physically inactive.

They report that participants in the highest tertile of sedentary time (more than 13 hours/day) exhibited a 44% increase in risk of stroke, compared with those in the lowest tertile (less than 11 hours/day), and the association remained significant when adjusted for several covariates, including moderate to vigorous activity.

“Even when controlling for the amount of other physical activity, sedentary behavior is still highly associated with risk of stroke. So even if you are active, long bouts of sedentary behavior are harmful,” Dr. Hooker commented.

They also found that longer bouts of sedentary time (more than 17 minutes at a time) were associated with a 54% higher risk of stroke than shorter bouts (less than 8 minutes).

“This suggests that breaking up periods of sedentary behavior into shorter bouts would be beneficial,” Dr. Hooker said.

“If you are going to spend the evening on the couch watching television, try to stand up and walk around every few minutes. Same for if you are sitting at a computer all day – try having a standing workstation, or at least take regular breaks to walk around,” he added.

NATIONAL HARBOR, MD. – While patients with multiple sclerosis (MS) don’t seem to be more likely to be infected with COVID-19, a neurologist told colleagues, the jury is still out over whether they face a higher mortality risk, especially if they take certain disease-modifying therapies (DMTs)

In regard to MS overall, “the data is conflicting, but any increased risk of mortality appears to be slight. And it appears to be chiefly the consequences associated with comorbidities as seen in other populations,” Joseph R. Berger, MD, said at the John F. Kurtzke Memorial Lecture at the annual meeting of the Consortium of Multiple Sclerosis Centers. “If you’re old, if you’re infirm, if you have obesity and cardiovascular disease and underlying pulmonary disease, you’re at risk of dying yourself. It’s not so much the MS,” said Dr. Berger, professor of neurology at the Hospital of the University of Pennsylvania and chief of the multiple sclerosis division at the University of Pennsylvania, Philadelphia.

Dr. Berger had his own COVID-19 story to tell: He couldn’t attend the conference in person because he was quarantining in Portugal since he tested positive. At press time, he was faring well but had reported 4 days of intense back pain.

In regard to MS and COVID-19, Dr. Berger said consistent research suggests that patients with MS aren’t at higher risk of COVID infection, although hospitalization may be more common. There may be a very small increase in risk of MS relapse in patients with COVID-19, he said, but pseudorelapses are far more common. As for mortality, he highlighted a 2021 pooled analysis of 18 studies with 5,634 patients that suggested they had a crude death rate of 1.97%, standardized lethality ratio of 1.24, and a 24% increased risk of death.

Dr. Berger is skeptical of these findings, however, in light of overall death rate numbers. Early on in the pandemic, the fatality rate in China was estimated at 2.3%.

He said he’s more convinced by a retrospective 2021 German COVID-19 study that compared 551 patients with MS to 156,973 other patients and found lower rates of ICU admission (17.1% in patients with MS vs. 22.7% in those without it), ventilation (9.8% vs. 14.5%), and in‐hospital mortality (11.1% vs. 19.3%).

Meanwhile, a 2021 systematic review found no increase in mortality among 4,310 patients with MS (3% death rate, 20.7% hospitalization), but the death risk was highest among those on no DMTs and those taking anti-CD20 monoclonal antibodies. The COViMS Registry has reported similar findings regarding the anti-CD20 drugs rituximab and ocrelizumab, Dr. Berger noted, and a pooled study of Italian and French data links the monoclonal antibodies to more severe COVID. A 2021 aggregated study also linked the antibodies to increased risk of hospitalization and ICU admission.

“Anti-CD20 monoclonal antibodies appear to increase the risk of hospitalization and perhaps the acquisition of the virus, ICU admission, maybe death,” he said, with rituximab appearing to pose the most risk, followed by ocrelizumab and ofatumumab. “And it appears that the platform [older] therapies may be associated with lesser mortality.”

As for nondrug factors, Dr. Berger said, studies have linked higher risk to age, male sex, and comorbidities.

COVID-19 vaccines are another area of concern, he said. “The recommendation is to administer vaccination prior to the initiation of the anti-CD20s, alemtuzumab, and cladribine, and wait a period of time. Three months is ideal, maybe a little longer, because it appears that the antibody response seems to be best as your CD19 count starts to return.”

Finally, Dr. Berger noted that “passive vaccination” is now available via Evusheld (tixagevimab and cilgavimab) as a preexposure treatment for people with moderate to severe immune compromise who may not mount an effective immune response to COVID-19 vaccination or those who are allergic.

NATIONAL HARBOR, MD. -- Over 25 years of clinical research, phase 3 trials of approved disease-modifying therapies (DMTs) for multiple sclerosis (MS) were overwhelmingly made up of White subjects, a new analysis finds, and many studies failed to report percentages of non-White subjects at all. Researchers also found that the websites of multiple major drug manufacturers don’t include any trial data about how medications may affect people of different races and ethnicities.

It’s clear that “non-White participants are significantly underreported and unrepresented,” said study corresponding author and Dell Medical School/The University of Texas at Austin neurologist Leorah Freeman, MD, PhD, in an interview. “Despite the globalization of MS trials over time, we do not see that trials are enrolling more diverse populations.”

The study was presented at the annual meeting of the Consortium of Multiple Sclerosis Centers and published in Neurology.

“The lack of diversity in MS research is something that has been sporadically discussed in the past. By conducting this systematic review of MS phase 3 trials, we wanted to put numbers on this issue and review the evidence systematically,” Dr. Freeman said. “By doing so, we hoped to raise awareness about the problem of underreporting and underrepresentation of non-White participants in trials so that we, as a community involved in MS research, can start having the difficult conversations needed for change to occur.”
 

25 years of clinical research

The researchers reviewed 44 phase 3 studies from 1995-2020 that represented 45 trials. “We wanted to capture data from the very first global trials being conducted for the approval of MS DMTs, and the first was published in 1995,” Dr. Freeman said. “We were interested in understanding the impact of trial globalization over a long period of time on diversity of enrollment.”

The studies include trials of mainstays of MS treatment such as interferon, glatiramer acetate, teriflunomide, dimethyl fumarate, diroximel fumarate, fingolimod, natalizumab, and others.

The researchers found that 17 (37.8%) of the trials did not report race or ethnicity, 14 (31.1%) reported race and ethnicity as proportion of White participants only, and 14 (31.1%) reported 2 or more races/ethnicities.

Of the 28 trials with racial breakdowns, the median percentage of White participants was 93.8% (range 78.5-99.6% across 28 studies), 1.9% for Black participants (range 0.1-8.1% across 14 studies), and 0.5% for Asian participants (range 0.1-14.5% across 11 studies).

The studies often failed to account for non-White subjects even though “Black people, in particular, have been shown to have a more severe disease course,” Dr. Freeman said.

A 2022 study of more than 2.6 million Southern California adults finds that prevalence of MS was similar among White and Black people at about 230 per 100,000. “Taken together with previous studies, these findings indicate that the burden of MS in the United States Black community has long been underrecognized,” the researchers wrote.

According to Dr. Freeman, it’s unclear why the studies were so dominated by White subjects. “Lack of awareness about the importance of this information likely explains why this information often goes unreported.”

She highlighted the TOWER (teriflunomide) and DEFINE and CONFIRM (dimethyl fumarate) studies as positive examples. “We noted the inclusion of trial sites in Asia and consequently a higher representation of Asian people with MS in those trials. We felt these studies were examples of how trial globalization can support better representation of underrepresented groups.”

And she noted that the ongoing CHIMES trial is examining the use of ocrelizumab in Black and Hispanic people with MS. “This study was designed in partnership with MS patients and advocacy groups to bridge gaps in clinical trial participation in these communities,” she said. “Innovative strategies were developed to increase participation of Black and Hispanic patients in this trial.”
 

What should happen next?

Going forward, Dr. Freeman said, “MS researchers, DMT manufacturers, sponsors, and publishers need to set better standards for racial and ethnic representation and reporting in trial publications.”

In an interview, epidemiologist Luisa N. Borrell, DDS, PhD, a professor who studies race and medicine at City University of New York, said the new study is valid and useful. She noted that it reflects the findings of a 2022 analysis of more than 20,500 clinical trials in the U.S. from 2000-2020: Only 43% reported racial/ethnic breakdowns, and the subjects were much more White than the population at large.

Possible reasons for the disparity include distrust among possible participants and lack of health literacy, she said, which are both “modifiable issues.”

Dr. Borrell added: “Clinical trials should aim to recruit populations affected by the outcome of interest. That would allow for the intervention to effectively treat those who need it the most. Moreover, the lack of diversity of trials brings issues of generalizability and transportability of the findings.”

No funding is reported. Dr. Freeman and some of the other study authors report various disclosures.

It happens quickly: A child on the autism spectrum bolts from supervision and disappears – an emergency called “autism elopement.” While any child can wander off, children on the autism spectrum face particular risks. These include the lure of water and the risk of drowning.

Some youngsters on the spectrum will follow this strong attraction to water and head for a nearby pond, river, or swimming pool. Such circumstances have made drowning a leading cause of death for these missing youths.

Autism elopement can happen any time. Summer can be especially dangerous. When the weather warms, the risk of drowning death rises, says Lori McIlwain, cofounder of the National Autism Association.

“The fatality risk is higher in May, June, July for that child to exit the setting unnoticed, especially if there’s an outdoor gathering and then they go directly to water,” Ms. McIlwain says. For instance, she says children can dart away during outdoor play, barbecues, gatherings, and other activities. Or they might wander off while vacationing near a beach or hotel pool.
 

Autism elopement

Many people don’t know about this risk, including some families with youngsters on the autism spectrum. The National Center for Missing and Exploited Children is working to change that – and find solutions.

About 12 years ago, “we started noticing a very disturbing trend that children with autism were going missing and they were having grave results,” says John Bischoff, vice president of the Center’s Missing Children Division.

The Center analyzed a decade of data on accidental deaths of children on the autism spectrum. Drowning was the #1 cause, accounting for 84% of those deaths.

In 2012, researchers reported on autism and wandering in the journal Pediatrics. They analyzed answers from about 1,000 families to an online survey on the topic. Parents who had children on the spectrum and children not on the spectrum responded. Nearly half of the parents said their child with autism had tried to wander off after age 4, and 26% had gone missing long enough to cause concern.

“Of those who went missing, 24% were in danger of drowning and 65% were in danger of traffic injury,” the researchers wrote. Children on the spectrum might also be drawn to traffic signs, highways, fire trucks, and trains.

In comparison, brothers and sisters of all ages who were not on the spectrum were much less likely to have wandered off.
 

Seeking a quiet place

It’s not entirely clear why children with autism are so drawn to water, Ms. McIlwain says. But there are some clues.

“What we see is that these children exit settings that are usually bothersome,” Ms. McIlwain says. “[Those settings are] loud, with a high amount of stimuli or stress or commotion, and they go to a quiet place, usually water in a quiet area. It’s calm. It’s peaceful.”

Water isn’t the only dangerous draw. When autism elopement happens, “they also go to the woods, they go to abandoned vehicles,” she says. “So any quiet thing is usually where they will head.”
 

A family’s loss

Beth Dilg, a mother in Maryland, lost her 7-year-old daughter, Savannah Martin, who was on the autism spectrum, to drowning in 2011. Ms. Dilg had been living in Oklahoma and raising her three children alone after separating from her husband. On a chilly February day, Savannah and her 2-year-old brother left their house after Ms. Dilg had asked her 11-year-old son to keep watch while she went into the bathroom for a few minutes.

When Ms. Dilg realized the two younger kids had left, she searched the property frantically. She shouted Savannah’s name repeatedly, but the child, who had limited language, didn’t come when called. “I feel like she knew what her name was,” Ms. Dilg says, “but it wasn’t like you’d call her name and she’d come to you.”

Ms. Dilg ran to a pond near her property after her 11-year-old son said that the two siblings were in the water. Ms. Dilg entered the water and grabbed her toddler, who had survived after having been kept afloat by his bicycle helmet. But when Ms. Dilg reached Savannah, she was already unresponsive. A neighbor helped pull the children out.

It can happen in any family. Even when a parent takes precautions, a child can slip out in a moment, perhaps while the parent is asleep or taking care of personal needs or if the child is at school or elsewhere.

“It’s unrealistic to say that you’d never take your eyes off your kid,” Ms. Dilg says.

She had tried to protect Savannah by starting her on swimming lessons, installing high locks on the doors, and trying to teach her about how to stay safe.

Still, children can be skillful in finding ways to escape, Ms. Dilg says. “These kids with autism are so smart. They may not be verbal, but they have this level of intelligence,” she says. “You always have to stay a step ahead of them.”

Ms. Dilg has been a longtime volunteer with Team HOPE, a peer support group with the National Center for Missing and Exploited Children. She offers emotional support to parents whose children are missing or who have died, including the parents of youngsters with autism who have drowned.
 

Teaching first responders

If a child on the autism spectrum goes missing, searching for them can be complicated by their condition. For instance, some children cannot speak or aren’t able to respond to searchers calling their name. The National Center for Missing and Exploited Children offers training to law enforcement and provides search protocols for first responders.

The center has drawn on expertise from Laurie Reyes, an officer with Maryland’s Montgomery County Police Department. In 2005, Ms. Reyes created a special unit within the department to focus on safety for people at risk for wandering. They have conditions that include autism/intellectual and developmental disabilities, as well as Alzheimer’s and other forms of dementia.

“We have a culture of awareness here,” Ms. Reyes says. All Montgomery County recruits and officers receive training in how to interact with those on the autism spectrum, who may not respond to police commands. Police also learn how to search, including immediately checking bodies of water. “We’ve had many times where we’ve located individuals in bodies of water,” Ms. Reyes says.

Don’t wait to call 911. When a child goes missing, time matters. Ms. Reyes advises families not to search on their own. “Call 911 right away,” she says.
 

Top safety tips to help prevent autism elopement

Use these tips to help keep kids on the autism spectrum safe and prevent drownings.

Secure your home. Use window and door alarms to alert you if a door or window becomes ajar. “Those door alarms are essential,” Ms. McIlwain says.

You can buy alarms online or get them free from the National Autism Association through its Big Red Safety Box program.

You can also buy portable door alarms for travel and arrange to have door alarms at your child’s school.

Ms. McIlwain advises securing the home with adequate locks and using baby monitors. Installing visual prompts, such as a stop sign on the door, might also cue a child not to leave.

Use personal identification. Ms. McIlwain says that children with autism must wear identification, such as a wristband, that includes their name, autism diagnosis, and the name and phone number of a contact person.

If children won’t wear a wristband, IDs on shoelaces are an option, she says. But parents should be aware that kids might leave without shoes or take them off before entering water.

Parents can also weigh the pros and cons of using tracking and locater devices, Ms. McIlwain says.

Identify triggers. “What’s going to make the child want to leave the setting? Is it noise? Is it a certain thing that they fear?” Ms. McIlwain says. “There’s always a reason.”

If parents can identify particular triggers, they can use calming techniques, for example, or provide headphones to counteract bothersome noises.

Teach safety skills, such as swimming lessons. Swimming lessons are important, Ms. McIlwain says. However, children with autism are often bothered by noise and commotion. So a regular swim class might not work for them.

Instead, Ms. McIlwain encourages parents to ask their local YMCA about special-needs swimming lessons or to search for such lessons online. What usually turns out to be best is to give the child a few private swimming lessons “with somebody who understands autism.”

For the child’s final lesson, they should swim fully clothed and with shoes on, Ms. McIlwain says. “A lot of our kids go straight into water fully clothed, and they just need to be able to be familiar with how that feels and the weight of that and be able to swim like that as well.”

If a child is drawn to water, discuss a scheduled time to go so that the youngster can wait, Ms. McIlwain says. “They can see that they’re going to get that water time. They’re going to be able to go to that place. They’re going to wait instead of trying to go on their own.”

Keep a close watch and team up. “When there is a family gathering or an outdoor barbecue, a lot of times, we all think, there are more adults here, so there are going to be more eyes on all the kids. And that always ends up being opposite, right?” Ms. McIlwain says.

Be specific about who is monitoring the child’s safety.

“We encourage parents to do the ‘Tag, you’re it’ game with one another. So you basically tag an adult who is responsible for keeping an eye on that child for a period of time so that there’s always supervision.”
 

Be prepared

There are a few things you can do now to be ready in case your child slips away. These measures may help find the child quickly.

Take photos today. Keep a full-length shot and a head shot of your child and store them electronically. If your child wanders away, you can immediately send the images to law enforcement to help them search.

Write a 911 script. Have this document ready in case your child wanders. It describes, among other things, points of interest that might draw your child, as well as locations of nearby bodies of water. By having it all written down, you’ll be able to share the information quickly with first responders. The Montgomery County Police Department has a “Wandering 911 Script” that you can download and use.

It happens quickly: A child on the autism spectrum bolts from supervision and disappears – an emergency called “autism elopement.” While any child can wander off, children on the autism spectrum face particular risks. These include the lure of water and the risk of drowning.

Some youngsters on the spectrum will follow this strong attraction to water and head for a nearby pond, river, or swimming pool. Such circumstances have made drowning a leading cause of death for these missing youths.

Autism elopement can happen any time. Summer can be especially dangerous. When the weather warms, the risk of drowning death rises, says Lori McIlwain, cofounder of the National Autism Association.

“The fatality risk is higher in May, June, July for that child to exit the setting unnoticed, especially if there’s an outdoor gathering and then they go directly to water,” Ms. McIlwain says. For instance, she says children can dart away during outdoor play, barbecues, gatherings, and other activities. Or they might wander off while vacationing near a beach or hotel pool.
 

Autism elopement

Many people don’t know about this risk, including some families with youngsters on the autism spectrum. The National Center for Missing and Exploited Children is working to change that – and find solutions.

About 12 years ago, “we started noticing a very disturbing trend that children with autism were going missing and they were having grave results,” says John Bischoff, vice president of the Center’s Missing Children Division.

The Center analyzed a decade of data on accidental deaths of children on the autism spectrum. Drowning was the #1 cause, accounting for 84% of those deaths.

In 2012, researchers reported on autism and wandering in the journal Pediatrics. They analyzed answers from about 1,000 families to an online survey on the topic. Parents who had children on the spectrum and children not on the spectrum responded. Nearly half of the parents said their child with autism had tried to wander off after age 4, and 26% had gone missing long enough to cause concern.

“Of those who went missing, 24% were in danger of drowning and 65% were in danger of traffic injury,” the researchers wrote. Children on the spectrum might also be drawn to traffic signs, highways, fire trucks, and trains.

In comparison, brothers and sisters of all ages who were not on the spectrum were much less likely to have wandered off.
 

Seeking a quiet place

It’s not entirely clear why children with autism are so drawn to water, Ms. McIlwain says. But there are some clues.

“What we see is that these children exit settings that are usually bothersome,” Ms. McIlwain says. “[Those settings are] loud, with a high amount of stimuli or stress or commotion, and they go to a quiet place, usually water in a quiet area. It’s calm. It’s peaceful.”

Water isn’t the only dangerous draw. When autism elopement happens, “they also go to the woods, they go to abandoned vehicles,” she says. “So any quiet thing is usually where they will head.”
 

A family’s loss

Beth Dilg, a mother in Maryland, lost her 7-year-old daughter, Savannah Martin, who was on the autism spectrum, to drowning in 2011. Ms. Dilg had been living in Oklahoma and raising her three children alone after separating from her husband. On a chilly February day, Savannah and her 2-year-old brother left their house after Ms. Dilg had asked her 11-year-old son to keep watch while she went into the bathroom for a few minutes.

When Ms. Dilg realized the two younger kids had left, she searched the property frantically. She shouted Savannah’s name repeatedly, but the child, who had limited language, didn’t come when called. “I feel like she knew what her name was,” Ms. Dilg says, “but it wasn’t like you’d call her name and she’d come to you.”

Ms. Dilg ran to a pond near her property after her 11-year-old son said that the two siblings were in the water. Ms. Dilg entered the water and grabbed her toddler, who had survived after having been kept afloat by his bicycle helmet. But when Ms. Dilg reached Savannah, she was already unresponsive. A neighbor helped pull the children out.

It can happen in any family. Even when a parent takes precautions, a child can slip out in a moment, perhaps while the parent is asleep or taking care of personal needs or if the child is at school or elsewhere.

“It’s unrealistic to say that you’d never take your eyes off your kid,” Ms. Dilg says.

She had tried to protect Savannah by starting her on swimming lessons, installing high locks on the doors, and trying to teach her about how to stay safe.

Still, children can be skillful in finding ways to escape, Ms. Dilg says. “These kids with autism are so smart. They may not be verbal, but they have this level of intelligence,” she says. “You always have to stay a step ahead of them.”

Ms. Dilg has been a longtime volunteer with Team HOPE, a peer support group with the National Center for Missing and Exploited Children. She offers emotional support to parents whose children are missing or who have died, including the parents of youngsters with autism who have drowned.
 

Teaching first responders

If a child on the autism spectrum goes missing, searching for them can be complicated by their condition. For instance, some children cannot speak or aren’t able to respond to searchers calling their name. The National Center for Missing and Exploited Children offers training to law enforcement and provides search protocols for first responders.

The center has drawn on expertise from Laurie Reyes, an officer with Maryland’s Montgomery County Police Department. In 2005, Ms. Reyes created a special unit within the department to focus on safety for people at risk for wandering. They have conditions that include autism/intellectual and developmental disabilities, as well as Alzheimer’s and other forms of dementia.

“We have a culture of awareness here,” Ms. Reyes says. All Montgomery County recruits and officers receive training in how to interact with those on the autism spectrum, who may not respond to police commands.

A novel blood-based assay could one day be used to diagnose Parkinson’s disease and possibly other chronic inflammatory conditions, according to investigators. In addition to being highly accurate, the assay, which detects changes in expression of cytochrome P450s, is faster and easier to perform than other Parkinson’s disease assays under investigation, reported lead author Kohei Ihara, PhD, of Kobe University, Japan, and colleagues.

“Effective diagnostic systems and biomarkers for patients without subjective motor symptoms have not yet been established,” the investigators wrote in Nature Scientific Reports. “Consequently, the poor diagnostic options for Parkinson’s disease delay the development of therapeutic approaches and medication. Therefore, the development of efficient diagnostic systems and biomarkers is crucial for overcoming Parkinson’s disease.”

According to Dr. Ihara and colleagues, various cytochrome P450 expression patterns and associated serum metabolites correlate with chronic conditions, making them possible markers of disease. To detect these changes, they developed the present assay. It relies upon recombinant P450s expressed on the surface of Escherichia coli. By mixing the E. coli with serum and Vivid, a fluorescent substrate, the investigators can measure “the inhibition rate of the Vivid decomposition reaction” that was driven by “serum metabolites associated with P450s,” revealing underlying expression and, if present, disease.

After some promising initial experiments with mouse models of ulcerative colitis and diabetes, Dr. Ihara and colleagues focused on a rat model of Parkinson’s disease. Evaluating inhibition rates associated with four P450s revealed area-under-the-curve (AUC) values of 0.814-0.914. Two of those P450s were also associated with progression of disease symptoms.

“Therefore, we concluded that the P450 inhibition assay could discriminate between Parkinson’s disease model rats and control rats,” the investigators wrote.

Next, the investigators tested the approach with a case-control study involving 20 patients with Parkinson’s disease and 20 healthy volunteers. Twelve P450s were analyzed, three of which revealed significant differences between patients with Parkinson’s disease and controls, with AUCs ranging from 0.740-0.775. Each of the three P450 enzymes also correlated significantly with stage of disease on the Hoehn & Yahr scale, although severity and frequency of symptoms were not reported.

To increase accuracy of the technique, the investigators developed a logistic regression model using two of the three P450s, generating an AUC of 0.910. Further testing showed that the P450 inhibition assay could distinguish between patients with Parkinson’s disease and Alzheimer’s disease, as well as other chronic inflammatory diseases.

“The P450 inhibition assay is easier to perform and is faster than other assays because this assay does not require pretreatment, such as purification of exosomes, and it involves a single enzymatic reaction,” the investigators wrote, suggesting that the assay may be suitable for real-world diagnosis.
 

‘Promising’ findings need replication

According to Douglas Galasko, MD, a neurologist and professor of neurosciences at UC San Diego Health, the reported accuracy of the assay “seems spectacular,” and the findings are “promising,” but they need to be replicated, “particularly in early-stage patients where the diagnosis [of Parkinson’s disease] is more difficult and important to make.” In practice, the assay would likely see greatest usage for “early diagnosis or diagnosis of unusual or challenging cases,” so accuracy testing needs to be conducted in this setting, he said.

Dr. Galasko, who was not involved in the study, predicted that liquid biopsy for detecting Parkinson’s disease is unlikely to hit the clinic floor anytime soon. “We’re not really close with blood-based biomarkers for Parkinson’s disease,” he said, “unlike the situation for Alzheimer’s disease, where there are several promising blood-based biomarkers.”

For diagnosing Parkinson’s disease, Dr. Galasko suggested that assays using skin biopsies to measure alpha-synuclein accumulation may be closer to approval.

The study was supported by JSPS KAKENHI Grant Number 20K20223 and the Sumitomo Electric Industries Group Corporate Social Responsibility Foundation. The investigators disclosed no conflicts of interest.

Twelve P450s were analyzed, three of which revealed significant differences between patients with Parkinson’s disease and controls, with AUCs ranging from 0.740-0.775. Each of the three P450 enzymes also correlated significantly with stage of disease on the Hoehn & Yahr scale, although severity and frequency of symptoms were not reported.

To increase accuracy of the technique, the investigators developed a logistic regression model using two of the three P450s, generating an AUC of 0.910. Further testing showed that the P450 inhibition assay could distinguish between patients with Parkinson’s disease and Alzheimer’s disease, as well as other chronic inflammatory diseases.

“The P450 inhibition assay is easier to perform and is faster than other assays because this assay does not require pretreatment, such as purification of exosomes, and it involves a single enzymatic reaction,” the investigators wrote, suggesting that the assay may be suitable for real-world diagnosis.
 

‘Promising’ findings need replication

According to Douglas Galasko, MD, a neurologist and professor of neurosciences at UC San Diego Health, the reported accuracy of the assay “seems spectacular,” and the findings are “promising,” but they need to be replicated, “particularly in early-stage patients where the diagnosis [of Parkinson’s disease] is more difficult and important to make.” In practice, the assay would likely see greatest usage for “early diagnosis or diagnosis of unusual or challenging cases,” so accuracy testing needs to be conducted in this setting, he said.

Dr. Galasko, who was not involved in the study, predicted that liquid biopsy for detecting Parkinson’s disease is unlikely to hit the clinic floor anytime soon. “We’re not really close with blood-based biomarkers for Parkinson’s disease,” he said, “unlike the situation for Alzheimer’s disease, where there are several promising blood-based biomarkers.”

For diagnosing Parkinson’s disease, Dr. Galasko suggested that assays using skin biopsies to measure alpha-synuclein accumulation may be closer to approval.

The study was supported by JSPS KAKENHI Grant Number 20K20223 and the Sumitomo Electric Industries Group Corporate Social Responsibility Foundation. The investigators disclosed no conflicts of interest.

SAN DIEGO – In a 2006 report of complications from laser dermatologic surgery, one of the authors, Dieter Manstein, MD, PhD, who had subjected his forearm to treatment with a fractional laser skin resurfacing prototype device, was included as 1 of the 19 featured cases.

Dr. Manstein, of the Cutaneous Biology Research Center in the department of dermatology at Massachusetts General Hospital, Boston, was exposed to three test spots in the evaluation of the effects of different microscopic thermal zone densities for the prototype device, emitting at 1,450 nm and an energy per MTZ of 3 mJ.

Two years later, hypopigmentation persisted at the test site treated with the highest MTZ density, while two other sites treated with the lower MTZ densities did not show any dyspigmentation. But he noticed something else during the experiment: He felt minimal to no pain as each test site was being treated.

“It took 7 minutes without any cooling or anesthesia,” Dr. Manstein recalled at the annual meeting of the American Society for Laser Medicine and Surgery. “It was not completely painless, but each time the laser was applied, sometimes I felt a little prick, sometimes I felt nothing.” Essentially, he added, “we created cell injury with a focused laser beam without anesthesia,” but this could also indicate that if skin is treated with a fractional laser very slowly, anesthesia is not needed. “Current devices are meant to treat very quickly, but if we [treat] slowly, maybe you could remove lesions painlessly without anesthesia.”

The observation from that experiment also led Dr. Manstein and colleagues to wonder: Could a focused laser beam pattern be used to assess cutaneous innervation? If so, they postulated, perhaps it could be used to not only assess nerve sensitivity of candidates for dermatologic surgery, but as a tool to help diagnose small fiber neuropathies such as diabetic neuropathy, and neuropathies in patients with HIV and sarcoidosis.

The current gold standard for making these diagnoses involves a skin biopsy, immunohistochemical analysis, and nerve fiber quantification, which is not widely available. It also requires strict histologic processing and nerve counting rules. Confocal microscopy of nerve fibers in the cornea is another approach, but is very difficult to perform, “so it would be nice if there was a simple way” to determine nerve fiber density in the skin using a focused laser beam, Dr. Manstein said.

With help from Payal Patel, MD, a dermatology research fellow at MGH, Dr. Manstein and colleagues have developed an intraepidermal nerve fiber density diagnostic device prototype that uses an erbium laser to conduct in vivo exposures, records each subject’s perception of a stimulus, and maps the areas of stimulus response. Current diameters being studied range from 0.076-1.15 mm and depths less than 0.71 mm. “We can focus the laser beam, preset the beam diameter, and very slowly, in a controlled manner, make a rectangular pattern, and after each time, inquire if the subject felt the pulse or not,” Dr. Manstein explained.

“This laser could become a new method for diagnosing nerve fiber neuropathies. If this works well, I think we can miniaturize the device,” he added.

Dr. Manstein disclosed that he is a consultant for Blossom Innovations, R2 Dermatology, and AVAVA. He is also a member of the advisory board for Blossom Innovations.

The combination of hearing loss and vision loss is linked to an eightfold increased risk of cognitive impairment, new research shows.

Investigators analyzed data on more than 5 million U.S. seniors. Adjusted results show that participants with hearing impairment alone had more than twice the odds of also having cognitive impairment, while those with vision impairment alone had more than triple the odds of cognitive impairment.

However, those with dual sensory impairment (DSI) had an eightfold higher risk for cognitive impairment.

In addition, half of the participants with DSI also had cognitive impairment. Of those with cognitive impairment, 16% had DSI, compared with only about 2% of their peers without cognitive impairment.

“The findings of the present study may inform interventions that can support older people with concurrent sensory impairment and cognitive impairment,” said lead author Esme Fuller-Thomson, PhD, professor, Factor-Inwentash Faculty of Social Work, University of Toronto.

“Special attention, in particular, should be given to those aged 65-74 who have serious hearing and/or vision impairment [because], if the relationship with dementia is found to be causal, such interventions can potentially mitigate the development of cognitive impairment,” said Dr. Fuller-Thomson, who is also director of the Institute for Life Course and Aging and a professor in the department of family and community medicine and faculty of nursing, all at the University of Toronto.

The findings were published online in the Journal of Alzheimer’s Disease  Reports.
 

Sensory isolation

Hearing and vision impairment increase with age; it is estimated that one-third of U.S. adults between the ages of 65 and 74 experience hearing loss, and 4% experience vision impairment, the investigators note.

“The link between dual hearing loss and seeing loss and mental health problems such as depression and social isolation have been well researched, but we were very interested in the link between dual sensory loss and cognitive problems,” Dr. Fuller-Thomson said.

Additionally, “there have been several studies in the past decade linking hearing loss to dementia and cognitive decline, but less attention has been paid to cognitive problems among those with DSI, despite this group being particularly isolated,” she said. Existing research into DSI suggests an association with cognitive decline; the current investigators sought to expand on this previous work.

To do so, they used merged data from 10 consecutive waves from 2008 to 2017 of the American Community Survey (ACS), which was conducted by the U.S. Census Bureau. The ACS is a nationally representative sample of 3.5 million randomly selected U.S. addresses and includes community-dwelling adults and those residing in institutional settings.

Participants aged 65 or older (n = 5,405,135; 56.4% women) were asked yes/no questions regarding serious cognitive impairment, hearing impairment, and vision impairment. A proxy, such as a family member or nursing home staff member, provided answers for individuals not capable of self-report.

Potential confounding variables included age, race/ethnicity, sex, education, and household income.
 

Potential mechanisms

Results showed that, among those with cognitive impairment, there was a higher prevalence of hearing impairment, vision impairment, and DSI than among their peers without cognitive impairment; in addition, a lower percentage of these persons had no sensory impairment (P < .001).

The prevalence of DSI climbed with age, from 1.5% for respondents aged 65-74 years to 2.6% for those aged 75-84 and to 10.8% in those 85 years and older.

Individuals with higher levels of poverty also had higher levels of DSI. Among those who had not completed high school, the prevalence of DSI was higher, compared with high school or university graduates (6.3% vs. 3.1% and 1.85, respectively).

After controlling for age, race, education, and income, the researchers found “substantially” higher odds of cognitive impairment in those with vs. those without sensory impairments.

“The magnitude of the odds of cognitive impairment by sensory impairment was greatest for the youngest cohort (age 65-74) and lowest for the oldest cohort (age 85+),” the investigators wrote. Among participants in the youngest cohort, there was a “dose-response relationship” for those with hearing impairment only, visual impairment only, and DSI.

Because the study was observational, it “does not provide sufficient information to determine the reasons behind the observed link between sensory loss and cognitive problems,” Dr. Fuller-Thomson said. However, there are “several potential causal mechanisms [that] warrant future research.”

The “sensory deprivation hypothesis” suggests that DSI could cause cognitive deterioration because of decreased auditory and visual input. The “resource allocation hypothesis” posits that hearing- or vision-impaired older adults “may use more cognitive resources to accommodate for sensory deficits, allocating fewer cognitive resources for higher-order memory processes,” the researchers wrote. Hearing impairment “may also lead to social disengagement among older adults, hastening cognitive decline due to isolation and lack of stimulation,” they added.

Reverse causality is also possible. In the “cognitive load on perception” hypothesis, cognitive decline may lead to declines in hearing and vision because of “decreased resources for sensory processing.”

In addition, the association may be noncausal. “The ‘common cause hypothesis’ theorizes that sensory impairment and cognitive impairment may be due to shared age-related degeneration of the central nervous system ... or frailty,” Dr. Fuller-Thomson said.
 

Parallel findings

The results are similar to those from a study conducted by Phillip Hwang, PhD, of the department of anatomy and neurobiology, Boston University, and colleagues that was published online in JAMA Network Open.

They analyzed data on 8 years of follow-up of 2,927 participants in the Cardiovascular Health Study (mean age, 74.6 years; 58.2% women).

Compared with no sensory impairment, DSI was associated with increased risk for all-cause dementia and Alzheimer’s disease, but not with vascular dementia.

“Future work in health care guidelines could consider incorporating screening of sensory impairment in older adults as part of risk assessment for dementia,” Nicholas Reed, AuD, and Esther Oh, MD, PhD, both of Johns Hopkins University, Baltimore, wrote in an accompanying editorial.
 

Accurate testing

Commenting on both studies, Heather Whitson, MD, professor of medicine (geriatrics) and ophthalmology and director at the Duke University Center for the Study of Aging and Human Development, Durham, N.C., said both “add further strength to the evidence base, which has really converged in the last few years to support that there is a link between sensory health and cognitive health.”

However, “we still don’t know whether hearing/vision loss causes cognitive decline, though there are plausible ways that sensory loss could affect cognitive abilities like memory, language, and executive function,” she said

Dr. Whitson, who was not involved with the research, is also codirector of the Duke/University of North Carolina Alzheimer’s Disease Research Center at Duke University, Durham, N.C., and the Durham VA Medical Center.

“The big question is whether we can improve patients’ cognitive performance by treating or accommodating their sensory impairments,” she said. “If safe and feasible things like hearing aids or cataract surgery improve cognitive health, even a little bit, it would be a huge benefit to society, because sensory loss is very common, and there are many treatment options,” Dr. Whitson added.

Dr. Fuller-Thomson emphasized that practitioners should “consider the full impact of sensory impairment on cognitive testing methods, as both auditory and visual testing methods may fail to take hearing and vision impairment into account.”

Thus, “when performing cognitive tests on older adults with sensory impairments, practitioners should ensure they are communicating audibly and/or using visual speech cues for hearing-impaired individuals, eliminating items from cognitive tests that rely on vision for those who are visually impaired, and using physical cues for individuals with hearing or dual sensory impairment, as this can help increase the accuracy of testing and prevent confounding,” she said.

Dr. Whitson, who was not involved with the research, is also codirector of the Duke/University of North Carolina Alzheimer’s Disease Research Center at Duke University, Durham, N.C., and the Durham VA Medical Center.

“The big question is whether we can improve patients’ cognitive performance by treating or accommodating their sensory impairments,” she said. “If safe and feasible things like hearing aids or cataract surgery improve cognitive health, even a little bit, it would be a huge benefit to society, because sensory loss is very common, and there are many treatment options,” Dr. Whitson added.

Dr. Fuller-Thomson emphasized that practitioners should “consider the full impact of sensory impairment on cognitive testing methods, as both auditory and visual testing methods may fail to take hearing and vision impairment into account.”

Thus, “when performing cognitive tests on older adults with sensory impairments, practitioners should ensure they are communicating audibly and/or using visual speech cues for hearing-impaired individuals, eliminating items from cognitive tests that rely on vision for those who are visually impaired, and using physical cues for individuals with hearing or dual sensory impairment, as this can help increase the accuracy of testing and prevent confounding,” she said.

NEW ORLEANS – Patients experiencing brain fog and other persistent symptoms of long COVID show significant deficits on neuropsychiatric testing that correspond with prior acute COVID-19 infection, adding to mounting evidence of the significant toll the chronic condition can have on mental health.

“Many clinicians have observed the symptoms we describe in this study, however this report is among the first which identify the specific deficits using neuropsychological testing to better characterize the syndrome,” Sean T. Lynch, MD, first author of a study on the issue presented at the annual meeting of the American Psychiatric Association, said in an interview.

Dr. Lynch, of the department of psychiatry, Westchester Medical Center Health System, Valhalla, N.Y., and his colleagues enrolled 60 participants who had experienced acute COVID-19 disease 6-8 months earlier and had undergone neuropsychological, psychiatric, medical, functional, and quality-of-life assessments. Results from the study were published online in the Journal of the Academy of Consultation–Liaison Psychiatry (2022 Jan 25. doi: 10.1016/j.jaclp.2022.01.003).

Among the study participants, 32 were seeking treatment for brain fog in a clinical program for survivors of COVID-19, while the remaining 28 were part of an ongoing longitudinal investigation of neuropsychological, medical, and psychiatric sequelae of COVID-19, but were not seeking care for the persistent symptoms.

Assessments for neurocognitive impairment included a battery of tests used in infectious and other diseases, including the Test of Premorbid Function, the Patient Assessment of Own Function, the Trail Making Test parts A and B, the Stroop Color and Word Test, and others.

Overall, the battery of assessments showed that 37 (62%) of participants had neuropsychological test impairment, with results below the 16th percentile in two tests, while 16 (27%) showed scores indicative of severe impairment (below the second percentile in at least one test and below the 16th percentile in one test).

Those reporting brain fog had scores that were even lower than expected on tests of attention, processing speed, memory, and executive function. And among those reporting brain fog, significantly more had scores reflecting severe impairment compared with the controls (38% vs. 14%; P < .04).

“Based on what we’ve observed in our patients and what others have previously reported, we did expect to find some impairment in this study sample,” Dr. Lynch noted.

“However, we were surprised to find that 27% of the study sample had extremely low neuropsychological test scores, meaning that they scored at least two standard deviations below the expected score on at least one neuropsychological test based on their age and level of education.”

The brain fog group also reported significantly higher levels of depression, fatigue, PTSD, and functional difficulties, and lower quality of life.

Severe impairment on the neuropsychological tests correlated with the extent of acute COVID-19 symptoms, as well as depression scores, number of medical comorbidities, and subjective cognitive complaints.

An analysis of serum levels of the inflammatory markers among 50 of the 60 participants showed that 45% of the patients had an elevated IL-6, 20% had elevated TNF-alpha, and 41% had elevated CRP, compared with reference ranges.

IL-6 levels were found to correlate with acute COVID-19 symptoms, the number of medical comorbidities, fatigue, and measures of executive function, while C-reactive protein (CRP) correlated with current COVID-19 symptoms and depression scores.

In terms of clinical factors that might predict low neuropsychological test scores, Dr. Lynch noted that the “markers that we found to be significant included severity of acute COVID-19 illness, current post-COVID-19 symptoms, measures of depression and anxiety, level of fatigue, and number of medical comorbidities.”

Dr. Lynch noted that the ongoing study will include up to 18-month follow-ups that are currently underway. “The [follow-ups] will examine if symptoms improve over time and evaluate if any intervention that took place was successful,” he said.


 

Survey supports findings

The detrimental effects of mental health symptoms in long COVID were further supported in another study at the APA meeting, an online survey of 787 survivors of acute COVID-19.

In the community survey, presented by Michael Van Ameringen, MD, a professor in the department of psychiatry and behavioral neurosciences at McMaster University, in Hamilton, Ont., all respondents (100%) reported having persistent symptoms of the virus, and as many as 68% indicated that they had not returned to normal functioning, despite only 15% of the respondents having been hospitalized with COVID-19.

A large proportion showed significant depression, anxiety, and posttraumatic stress disorder (PTSD), and the most commonly reported persistent symptoms were fatigue in 75.9% of respondents, brain fog in 67.9%, concentration difficulties in 61.1%, and weakness in 51.2%.

As many as 88.2% of patients said they experienced persistent neurocognitive symptoms, with poor memory and concentration; 56% reported problems with word finding; and 54.1% had slowed thinking.

The respondents showed high rates of anxiety (41.7%) as well as depression (61.4%) as determined by scores above 9 on the Generalized Anxiety Disorder–7 (GAD-7) and Patient Health Questionnaires (PHQ-9).

As many as 40.5% of respondents showed probable PTSD, with scores above 30 on the PTSD checklist (PCL-5). Their mean resilience score on the Brief Resilient Coping Scale was 13.5, suggesting low resilience.

Among the respondents, 43.3% said they had received past treatment for mental health, while 33.5% were currently receiving mental health treatment.

Dr. Van Ameringen noted the important limitation of the study being an online survey with no control group, but said the responses nevertheless raise the question of the role of prior psychiatric disorders in long COVID.

“In our sample, 40% of respondents had a past psychiatric history, so you wonder if that also makes you vulnerable to long COVID,” he said in an interview.

“About a third were getting psychiatric help, but I think the more impaired you are, the more likely you are to seek help.”

Those who were hospitalized with COVID-19 were at a higher risk of PTSD compared with those not hospitalized (P < .001), as were those under the age of 30 (P < .05) or between 31 and 50 vs. over 50 (P < .01).

Dr. Van Ameringen noted that the survey’s high rate of subjects who had not returned to normal functioning was especially striking.

“This is not a minor issue – these are people who are no longer functioning in society,” he said.
 

In pandemics, the brain tends to be ‘overlooked’

Further addressing the neurological effects of COVID-19 at the APA meeting, Avindra Nath, MD, clinical director of the National Institutes of Neurologic Disorders and Stroke in Bethesda, Md., noted that the persisting cognitive and psychiatric symptoms after illness, such as brain fog and depression and anxiety, are not necessarily unique to COVID-19.

“We have seen this before,” he said. “There have been at least seven or eight human coronaviruses, and the interesting thing is each one affects the brain and causes neurological complications.”

The effects are classified differently and have slightly different receptors, “but the consequences are the same.”

Of note, however, research published in The Lancet Psychiatry (2021 May. doi: 10.1016/S2215-0366[21]00084-5) revealed that symptoms such as dementia, mood, and anxiety are significantly higher after COVID-19 compared with other respiratory infections, with the differences increasing at 180 days since the index event.

Dr. Nath noted that, over the decades, he has observed that in pandemics “the brain tends to get overlooked.” He explained that “what can be most important in the end is what happened in the brain, because those are the things that really cause the long-term consequences.”

“These patients are depressed; they have dementia, they have brain fog, and even now that we recognize these issues, we haven’t done a very good job of studying them,” he said. “There’s so much we still don’t know, and a lot of patients are left with these symptoms and nowhere to go.”

Dr. Lynch, Dr. Van Ameringen, and Dr. Nath had no disclosures to report.
