In this modern age of health care where telemedicine rules, conversational agents (CAs) that use text messaging systems are becoming a major mode of communication.

Many people are familiar with voice-enabled agents, such as Apple’s Siri, Google Now, and Microsoft’s Cortana. However, CAs come in different forms of complexity, ranging from a short message service–based texting platform to an embodied conversational agent (ECA).

ECAs allow participants to interact with a physical or graphical figure that simulates a person in appearance, behavior, and dialect. These are essentially virtual humans, or avatars, who talk with participants. By taking greater advantage of these automated agents, some have projected there may be $11 billion in combined cost savings across a variety of business sectors by 2023.¹ The health care field is one sector in which CAs can play an important role. Because of their accessibility, CAs have the potential to improve mental health by combating health care inequities and stigma, encouraging disclosure from participants, and serving as companions during the COVID-19 pandemic.

CAs provide accessible health care for rural, low socioeconomic status (SES), and minority communities in a variety of advantageous ways. For example, one study found that long-term use of a text-based agent that combines motivational interviewing and cognitive-behavioral therapy (CBT) can support smoking cessation in adolescents of low SES.²

CAs can help vulnerable participants advocate for themselves and proactively maintain their mental health through access to health care resources. In specific cases, these agents equalize health care treatment for different populations. Even though some participants live in secluded areas or are blocked by barriers, these text-based agents can still provide self-help intervention for them at any time on an individual basis, regardless of their location or socioeconomic status. Furthermore, they serve as highly cost-effective mental health promotion tools for large populations, some of which might not otherwise be reached by mental health care.

In combating mental illnesses such as depression and anxiety, studies have found that CAs are great treatment tools. For example, participants in an experimental group who received a self-help program based on CBT from a text-based CA named Woebot experienced significantly reduced depression symptoms when compared to the control group of participants, who received only information from a self-help electronic book.³ As a result, CAs might prove successful in treating younger populations who find online tools more feasible and accessible. Often, this population self-identifies depressive and anxiety symptoms without consulting a health care professional. Thus, this tool would prove useful to those who are bothered by the stigma of seeing a mental health professional.

Virtual human–based CAs also encourage participants to disclose more information in a nonjudgmental manner, especially among people with diseases with stigma. CAs use neutral languages, which may be helpful when dealing with stigmatized issues such as HIV, family planning, and abortion care because this heightens confidentiality and privacy. When participants believe that the agent does not “judge” or evaluate their capabilities, this elicits more sensitive information from them. For example, one study found that military service members who believed that they were interacting with a computer rather than a human operator reported lower fear of self-disclosure, displayed more sadness, and were rated by observers as more willing to disclose posttraumatic stress disorder symptoms.⁴ Additional findings show that participants prefer CAs when topics are highly sensitive and more likely to evoke negative self-admissions.

In what we hope will soon be a post–COVID-19 landscape of medicine, CAs are fast being used on the front lines of health care technology. Empathetic CAs can combat adverse effects of social exclusion during these pressing times. Etsuko Ishii, a researcher affiliated with the Hong Kong University of Science and Technology, and associates demonstrated that a virtual CA was as effective as a COVID-19 companion because it uses natural language processing (NLP) and nonverbal facial expressions to give users the feeling that they are being treated with empathy.⁵ While minimizing the number of in-person interactions that could potentially spread COVID-19, these agents promote virtual companionship that mirrors natural conversations and provide emotional support with psychological safety as participants express their pent-up thoughts. Not only do these agents help recover mood quickly, but they also have the power to overcome geographic barriers, be constantly available, and alleviate the high demand for mental health care. As a result, CAs have the potential to facilitate better communication and sustain social interactions within the isolated environment the pandemic has created.

CAs can predict, detect, and determine treatment solutions for mental health conditions based on behavioral insights. These agents’ natural language processing also allows them to be powerful therapeutic agents that can serve different communities, particularly for populations with limited access to medical resources. As the use of CAs becomes more integrated into telemedicine, their utility will continue to grow as their proven versatility in many situations expands the boundaries of health care technology.

At Wayne State University’s Stress, Trauma, and Anxiety Research Clinic (STARC) in Michigan, researchers are developing novel interventions for treating some very ancient phobias hardwired into the human brain. By using augmented reality as means of conducting exposure therapy, STARC researchers – including Shantanu Madaboosi, Rakesh Ramaswamy, and Lana Grasser – and STARC director Arash Javanbakht, MD, have produced compelling evidence that they can free patients of their often debilitating fears of spiders, dogs, and snakes. Yet their work doesn’t stop there, and research into treating anxiety and posttraumatic stress disorder among first responders and others with high-stress occupations is ongoing.

This news organization spoke with Dr. Javanbakht, a psychiatrist, about the technological advances that have made this work possible; the future of remote-based psychiatry; and his tarantula colleague, Tony.
 

Augmenting exposure therapy

How did you begin using artificial intelligence as a way of delivering exposure therapy?

Exposure therapy is a very effective treatment for phobias, obsessive-compulsive disorder, and PTSD. But the problem we had is that, if someone comes to me and says they’re afraid of dogs, snakes, or spiders, I don’t have those in my office. Or, if its social phobia, I can’t create those scenarios. So, despite being such an effective treatment, it’s not utilized as much as it should be.

Several years ago, I saw a TED talk by the CEO of an augmented reality company who happened to be a neuroscientist. I thought the concept was amazing, because it offered a way to overcome those limitations.

Mixed augmented reality allows us to bring all those feared objects to the clinic. I can bring my Labrador to the office for someone who’s afraid of dogs, and they can get the exposure to that one dog. But we know good exposure therapy needs to be generalizable, with as many different breeds of dogs as possible, and is context dependent. If the patient sees a dog in their neighborhood, their fear response may come back. Doing it in a real-life context, and offering as many contexts as possible, makes it more effective.

Augmented reality allows all of these options because you can have as many different types of virtual objects as you want, and the difference between augmented reality and virtual reality is that augmented reality happens in a real-life context. You wear the goggles and you can walk around the environment and track the object, so the context is more realistic.
 

When did you begin researching augmented reality as a clinical tool?

I became a faculty member here in 2015, right out of my residency training, and I think it was around 2016 or 2017 that we began this work.

I’m very much involved in exposure therapy, utilize it myself, train others, and research how it works and changes the brain. I knew the ins and outs and what would make a better exposure therapy, based on my knowledge of neuroscience.

We spend time thinking about how we can apply these neuroscientific principles in software that can also be easily used by a not very technologically savvy therapist. Because that has been a big barrier when it comes to technology and human use in medicine.

Initially, we had a company create the software for us, but we’ve since brought all the programming inside.

The cool thing about these augmented reality devices is that they have excellent surface mapping. As soon as the person wears the goggles, it automatically maps the surfaces and provides a 3D view of the patient’s environment on the therapist’s computer. Say you’re treating a patient with a fear of spiders. Through drop-down menus, the therapist can choose what type of spider, its color and size, where it should be placed, and the motion. I can choose to move the spider from 6 feet away on the floor to the walls to the ceiling.
 

Virtual phobias, real fear

A big question for a lot of people was if the spiders are virtual, will they be scary, because it has to be realistic enough to create a fear response for the therapy to work. We use a couple of wires that you can put on a person’s finger and hook them up to a tablet or a cell phone. This provides an online measure of a person’s autonomic sympathetic response.

Like a lie detector test?

Exactly. We put that on their fingers and exposed them to a real-life tarantula and to our virtual tarantulas, and the fear response was no different. That means these do create an objective fear reaction in the body.

We also had people who said, “I know this is not real. I won’t be scared.” And when we started the therapy, it was with a tiny spider 5 meters away from them, and they’d lift their legs off the floor.

With the treatment, we’d come to one room and start with a very little spider, far from them. Then gradually we move them up to bigger, more diverse types of spiders, which are moving around. The patient comes near and tries to touch them.

Then at some point, I’d put a spiderweb on the door, put a few spiders on that, open the door, and have the patient walk through it. They kept walking through this spiderweb.

When they were desensitized to these spiders in this context – and as I said, context is important – we’d go to another room. This was darker, more like a basement, and we’d continue the same thing. That would actually take much less time because they already had desensitized a lot.

In our field, sense of control is very important, especially for when a patient goes home. So at the end, I’d leave the room and talk to the patient via a baby monitor. The patient was surrounded by 20 tarantulas, without the prompt moving around the environment.

Now that they’re desensitized to my virtual spiders, the question is, how would that apply to a real spider? So, we had a real live tarantula, whose name was Tony Stark, because we’re the STARC lab. We’d put Tony at the end of a long hallway before the treatment and see how close the patients could get to him.

Everybody who got the treatment was able to touch the tank containing the tarantula. It was only one treatment session; nobody’s was longer than 1 hour, and the average treatment time was 38 minutes.
 

That’s pretty effective.

It’s pretty good, compared with other studies. And I believe this is because of all the components I mentioned: being able to use your real environment; combining it with the real tarantula; the variety of the types of the feared objects; and, of course, giving the patient a sense of autonomy at the end.

Then we had to see how prolonged the effects are. We had them come in 1 week and 1 month after the treatment. I’d remind them of the principles of good exposure therapy and ask them to keep practicing at home between the sessions, looking at pictures and videos. But we never tested who did or did not do it.

After 1 week and 1 month, the effects were either the same or better. A larger number of people at 1 month were able to touch the tarantula than right after treatment.
 

Treating PTSD in first responders

Did you start with spiders and dogs because those are common fears?

We started with spiders because that worked with the initial goal of creating a prototype. Spiders’ behavior is simple enough for the programming, which takes a lot of time. Another reason for choosing spiders was that we had a lot of other studies of real and virtual reality exposure therapy to compare against.

I think another reason for our success is that, when you do real exposure therapy, you have just one scared tarantula in the corner of their tank, and they don’t listen to you. But my spiders listen to me and do exactly what I tell them.

After our initial success, we obtained more funds to expand it to other phobias. The cool thing is that we don’t need separate software for different phobias. You can choose dogs or snakes, add it to the person’s environment, and decide their behaviors.

We just started a clinical trial using dogs, and another group in Turkey is running a clinical trial with dogs. Eastern Michigan University is working with spiders. And a clinic at the University of Nebraska Medical Center is going to start using them in real-world clinics, not for research.

We have another project whose goal is helping reduce the impact of trauma and also treating PTSD in first responders, who are exposed to a lot of horrible things. Rates of PTSD are around 20%-30% among cops, firefighters, and EMS personnel.

They commonly find it very painful being in crowds because the fight-or-flight instinct in the brain is constantly screening for any sign of threat in their environment. We’re working on them walking into an empty room wearing the goggles, and then their therapist can scale the stimulus up and down.

There’ll be two people in front of you talking to each other, and then another group comes in, and people get louder. People can look at you and talk to you. There’s kids running, Fourth of July fireworks, and other things that might bother someone who’s been involved in gun- or explosion-related traumas. You gradually scale up when the person is next to their therapist.

Another thing we’re doing is related to cardiopulmonary resuscitation. If a young person dies in a CPR situation, that is really painful and traumatic. So, for exposure therapy to that, we’re creating a difficult CPR scenario when that person may die. The responder wears the goggles and basically watches a group of people doing CPR while standing next to a therapist who can help them navigate it and then scale it off.

Another goal is combining this with telemedicine, where the person can do it in their real-life environment. Imagine a person with military trauma. You can put them back in the barracks, connected with their psychiatrists via telemedicine. Then we would put humans in military fatigues near them and have them interact with them to feel comfortable with that situation.
 

What else is next for you and your group?

The next biggest challenge that we’re tackling is PTSD, because of course creating human-encounter scenarios is much more complicated than spiders and dogs. We’re in the midst of developing this so we can basically bring it to people’s homes.

We’ve been working with some military personnel to see if we can basically give a device to a veteran with PTSD, so they can go home and practice on their own.

There’s another possibility for training. Let’s take the example of a police force, which can have a lot of difficulties and mistakes because of lack of exposure and training. They can wear these goggles, get fully geared up, and be placed in encounters with people of different backgrounds, of different severity, with people who could be severely mentally ill or present different challenges for the officers.

Those situations can teach them a lot. I’m the creator of this thing, but even I’m often surprised by how realistic this technology can be. I find myself interacting with avatars the same way I would if they were real humans. I actually had one of my colleagues, when we started launching the programming with the dogs, immediately jump back. It’s just like the animal brain reacts to them.
 

Last question: Do you actually interact with Tony, the tarantula?

Oh, Tony is my friend. Unfortunately, he’s not with our lab at this moment. He’s on a sabbatical at Eastern Michigan University for their clinical trials. But yes, I’ve held him. He’s very friendly.

We’d put Tony at the end of a long hallway before the treatment and see how close the patients could get to him.

Everybody who got the treatment was able to touch the tank containing the tarantula. It was only one treatment session; nobody’s was longer than 1 hour, and the average treatment time was 38 minutes.
 

That’s pretty effective.

It’s pretty good, compared with other studies. And I believe this is because of all the components I mentioned: being able to use your real environment; combining it with the real tarantula; the variety of the types of the feared objects; and, of course, giving the patient a sense of autonomy at the end.

Then we had to see how prolonged the effects are. We had them come in 1 week and 1 month after the treatment. I’d remind them of the principles of good exposure therapy and ask them to keep practicing at home between the sessions, looking at pictures and videos. But we never tested who did or did not do it.

After 1 week and 1 month, the effects were either the same or better. A larger number of people at 1 month were able to touch the tarantula than right after treatment.
 

Treating PTSD in first responders

Did you start with spiders and dogs because those are common fears?

We started with spiders because that worked with the initial goal of creating a prototype. Spiders’ behavior is simple enough for the programming, which takes a lot of time. Another reason for choosing spiders was that we had a lot of other studies of real and virtual reality exposure therapy to compare against.

I think another reason for our success is that, when you do real exposure therapy, you have just one scared tarantula in the corner of their tank, and they don’t listen to you. But my spiders listen to me and do exactly what I tell them.

After our initial success, we obtained more funds to expand it to other phobias. The cool thing is that we don’t need separate software for different phobias. You can choose dogs or snakes, add it to the person’s environment, and decide their behaviors.

We just started a clinical trial using dogs, and another group in Turkey is running a clinical trial with dogs. Eastern Michigan University is working with spiders. And a clinic at the University of Nebraska Medical Center is going to start using them in real-world clinics, not for research.

We have another project whose goal is helping reduce the impact of trauma and also treating PTSD in first responders, who are exposed to a lot of horrible things. Rates of PTSD are around 20%-30% among cops, firefighters, and EMS personnel.

They commonly find it very painful being in crowds because the fight-or-flight instinct in the brain is constantly screening for any sign of threat in their environment. We’re working on them walking into an empty room wearing the goggles, and then their therapist can scale the stimulus up and down.

There’ll be two people in front of you talking to each other, and then another group comes in, and people get louder. People can look at you and talk to you. There’s kids running, Fourth of July fireworks, and other things that might bother someone who’s been involved in gun- or explosion-related traumas. You gradually scale up when the person is next to their therapist.

Another thing we’re doing is related to cardiopulmonary resuscitation. If a young person dies in a CPR situation, that is really painful and traumatic. So, for exposure therapy to that, we’re creating a difficult CPR scenario when that person may die. The responder wears the goggles and basically watches a group of people doing CPR while standing next to a therapist who can help them navigate it and then scale it off.

Another goal is combining this with telemedicine, where the person can do it in their real-life environment. Imagine a person with military trauma. You can put them back in the barracks, connected with their psychiatrists via telemedicine. Then we would put humans in military fatigues near them and have them interact with them to feel comfortable with that situation.
 

What else is next for you and your group?

The next biggest challenge that we’re tackling is PTSD, because of course creating human-encounter scenarios is much more complicated than spiders and dogs. We’re in the midst of developing this so we can basically bring it to people’s homes.

We’ve been working with some military personnel to see if we can basically give a device to a veteran with PTSD, so they can go home and practice on their own.

There’s another possibility for training. Let’s take the example of a police force, which can have a lot of difficulties and mistakes because of lack of exposure and training. They can wear these goggles, get fully geared up, and be placed in encounters with people of different backgrounds, of different severity, with people who could be severely mentally ill or present different challenges for the officers.

Those situations can teach them a lot. I’m the creator of this thing, but even I’m often surprised by how realistic this technology can be. I find myself interacting with avatars the same way I would if they were real humans. I actually had one of my colleagues, when we started launching the programming with the dogs, immediately jump back. It’s just like the animal brain reacts to them.
 

Last question: Do you actually interact with Tony, the tarantula?

Oh, Tony is my friend. Unfortunately, he’s not with our lab at this moment. He’s on a sabbatical at Eastern Michigan University for their clinical trials. But yes, I’ve held him. He’s very friendly.

A version of this article first appeared on Medscape.com.

At Wayne State University’s Stress, Trauma, and Anxiety Research Clinic (STARC) in Michigan, researchers are developing novel interventions for treating some very ancient phobias hardwired into the human brain. By using augmented reality as means of conducting exposure therapy, STARC researchers – including Shantanu Madaboosi, Rakesh Ramaswamy, and Lana Grasser – and STARC director Arash Javanbakht, MD, have produced compelling evidence that they can free patients of their often debilitating fears of spiders, dogs, and snakes. Yet their work doesn’t stop there, and research into treating anxiety and posttraumatic stress disorder among first responders and others with high-stress occupations is ongoing.

This news organization spoke with Dr. Javanbakht, a psychiatrist, about the technological advances that have made this work possible; the future of remote-based psychiatry; and his tarantula colleague, Tony.
 

Augmenting exposure therapy

How did you begin using artificial intelligence as a way of delivering exposure therapy?

Exposure therapy is a very effective treatment for phobias, obsessive-compulsive disorder, and PTSD. But the problem we had is that, if someone comes to me and says they’re afraid of dogs, snakes, or spiders, I don’t have those in my office. Or, if its social phobia, I can’t create those scenarios. So, despite being such an effective treatment, it’s not utilized as much as it should be.

Several years ago, I saw a TED talk by the CEO of an augmented reality company who happened to be a neuroscientist. I thought the concept was amazing, because it offered a way to overcome those limitations.

Mixed augmented reality allows us to bring all those feared objects to the clinic. I can bring my Labrador to the office for someone who’s afraid of dogs, and they can get the exposure to that one dog. But we know good exposure therapy needs to be generalizable, with as many different breeds of dogs as possible, and is context dependent. If the patient sees a dog in their neighborhood, their fear response may come back. Doing it in a real-life context, and offering as many contexts as possible, makes it more effective.

Augmented reality allows all of these options because you can have as many different types of virtual objects as you want, and the difference between augmented reality and virtual reality is that augmented reality happens in a real-life context. You wear the goggles and you can walk around the environment and track the object, so the context is more realistic.
 

When did you begin researching augmented reality as a clinical tool?

I became a faculty member here in 2015, right out of my residency training, and I think it was around 2016 or 2017 that we began this work.

I’m very much involved in exposure therapy, utilize it myself, train others, and research how it works and changes the brain. I knew the ins and outs and what would make a better exposure therapy, based on my knowledge of neuroscience.

We spend time thinking about how we can apply these neuroscientific principles in software that can also be easily used by a not very technologically savvy therapist. Because that has been a big barrier when it comes to technology and human use in medicine.

Initially, we had a company create the software for us, but we’ve since brought all the programming inside.

The cool thing about these augmented reality devices is that they have excellent surface mapping. As soon as the person wears the goggles, it automatically maps the surfaces and provides a 3D view of the patient’s environment on the therapist’s computer. Say you’re treating a patient with a fear of spiders. Through drop-down menus, the therapist can choose what type of spider, its color and size, where it should be placed, and the motion. I can choose to move the spider from 6 feet away on the floor to the walls to the ceiling.
 

Virtual phobias, real fear

A big question for a lot of people was if the spiders are virtual, will they be scary, because it has to be realistic enough to create a fear response for the therapy to work. We use a couple of wires that you can put on a person’s finger and hook them up to a tablet or a cell phone. This provides an online measure of a person’s autonomic sympathetic response.

Like a lie detector test?

Exactly. We put that on their fingers and exposed them to a real-life tarantula and to our virtual tarantulas, and the fear response was no different. That means these do create an objective fear reaction in the body.

We also had people who said, “I know this is not real. I won’t be scared.” And when we started the therapy, it was with a tiny spider 5 meters away from them, and they’d lift their legs off the floor.

With the treatment, we’d come to one room and start with a very little spider, far from them. Then gradually we move them up to bigger, more diverse types of spiders, which are moving around. The patient comes near and tries to touch them.

Then at some point, I’d put a spiderweb on the door, put a few spiders on that, open the door, and have the patient walk through it. They kept walking through this spiderweb.

When they were desensitized to these spiders in this context – and as I said, context is important – we’d go to another room. This was darker, more like a basement, and we’d continue the same thing. That would actually take much less time because they already had desensitized a lot.

In our field, sense of control is very important, especially for when a patient goes home. So at the end, I’d leave the room and talk to the patient via a baby monitor. The patient was surrounded by 20 tarantulas, without the prompt moving around the environment.

Now that they’re desensitized to my virtual spiders, the question is, how would that apply to a real spider? So, we had a real live tarantula, whose name was Tony Stark, because we’re the STARC lab. We’d put Tony at the end of a long hallway before the treatment and see how close the patients could get to him.

The Devil’s own face covering?

It’s been over a year and a half since the COVID-19 emergency was declared in the United States, and we’ve been starting to wonder what our good friend SARS-CoV-2 has left to give. The collective cynic/optimist in us figures that the insanity can’t last forever, right?

Maybe not forever, but …

A group of parents is suing the Central Bucks (Pa.) School District over school mask mandates, suggesting that the district has no legal authority to enforce such measures. Most of their arguments, Philadelphia Magazine says, are pretty standard stuff: Masks are causing depression, anxiety, and discomfort in their children; masks are a violation of their constitutional rights; and “masks are being used as a control mechanism over the population.”

There are some unusual claims, though. One of the parents, Shannon Harris, said that “wearing masks interferes with their religious duty to spread the word of God and forces them to participate in a satanic ritual,” according to the Philadelphia Inquirer.

Philadelphia Magazine decided to check on that “satanic ritual” claim by asking an expert, in this case a spokesperson for the Church of Satan. The Reverend Raul Antony said that “simply ‘wearing a mask’ is not a Satanic ritual, and anyone that genuinely thinks otherwise is a blithering idiot,” adding that the group’s rituals were available on its website.

You’re the (hurricane) wind beneath my wings

Marriage isn’t easy. From finances to everyday stressors like work and children, maintaining a solid relationship is tough. Then a natural disaster shows up on top of everything else, and marriages actually improve, researchers found.

pxfuel

In a study published by Psychological Science, researchers surveyed 231 newlywed couples about the satisfaction of their marriage before and after Hurricane Harvey in 2017. They found after the hurricane couples had a “significant boost” in the satisfaction of their relationship.

One would think something like this would create what researchers call a “stress spillover,” creating a decrease in relationship satisfaction. Destruction to your home or even displacement after a natural disaster seems pretty stressful. But, “a natural disaster can really put things in perspective. People realize how important their partner is to them when they are jolted out of the day-to-day stress of life,” said Hannah Williamson, PhD, the lead author of the study.

And although everyone saw an increase, the biggest jumps in relationship satisfaction belonged to the people who were most unhappy before the hurricane. Unfortunately, the researchers also found that the effects were only temporary and the dissatisfaction came back within a year.

Dr. Williamson thinks there may be something to these findings that can be beneficial from a therapy standpoint where “couples can shift their perspective in a similar way without having to go through a natural disaster.”

Let’s hope she’s right, because the alternative is to seek out a rampaging hurricane every time your relationship is on the rocks, and that just seems impractical after the second or third year.
 

Not-so-essential oils

Many people use essential oils as a way to unwind and relax. Stressed? Can’t sleep? There’s probably an essential oil for that. However, it seems like these days a lot of things we love and/or think are good for us have a side that’s not so.

According to the Centers for Disease Control and Prevention, a woman from Georgia died from a rare bacteria called Burkholderia pseudomallei. There have been three previous infections in Kansas, Minnesota, and Texas throughout 2021; two of the four infections were in children. Melioidosis, the disease caused by B. pseudomallei, is usually found in southeast Asia and isn’t obvious or easy to diagnose, especially in places like decidedly untropical Minnesota.

The Georgia case was the real break in this medical mystery, as the infection was traced back to a Walmart product called “Better Homes and Gardens Essential Oil Infused Aromatherapy Room Spray with Gemstones” (a very pithy name). The bacteria were in the lavender and chamomile scent. The CDC is investigating all other product scents, and Walmart has recalled all lots of the product.

If you’ve got that particular essential oil, it’s probably for the best that you stop using it. Don’t worry, we’re sure there’s plenty of other essential oil–infused aromatherapy room sprays with gemstones out there for your scent-based needs.
 

Welcome to the Ministry of Sleep-Deprived Walks

Walking is simple, right? You put one foot in front of the other, and soon you’re walking out the door. Little kids can do it. Even zombies can walk, and they don’t even have brains.

riskms/Getty

Research from MIT and the University of São Paulo has shown that walking is a little trickier than we might think. One researcher in particular noticed that student volunteers tended to perform worse toward the end of semesters, as project deadlines and multiple exams crashed over their heads and they were deprived of solid sleep schedules.

In a study published in Scientific Reports, our intrepid walking researchers had a collection of students monitor their sleep patterns for 2 weeks; on average, the students got 6 hours per night, though some were able to compensate on weekends. On the final day of a 14-day period, some students pulled all-nighters while the rest were allowed to sleep as usual. Then all students performed a walking test involving keeping time with a metronome.

To absolutely no one’s surprise, the students who performed all-nighters before being tested walked the worst, but between the other students, the ones who compensated for sleep deprivation on weekends did better than those who got 6 hours every night, despite getting a similar amount of sleep overall. This effect persisted even when the compensating students performed their walking tests late in the week, just before they got their weekend beauty sleep.

The moral of the story? Sleep is good, and you should get more of it. But if you can’t, sleep in on weekends. Science has given you permission. All those suburban dads looking to get their teenagers up at 8 in the morning must be sweating right now.

Marijuana use is now a legal activity in many parts of the United States, but those managing patients with psychiatric disorders are in the difficult position of determining whether this use is helpful, harmful, or irrelevant to the underlying illness on the basis of limited and largely incomplete data, according to an overview of this issue presented at the virtual Psychopharmacology Update presented by Current Psychiatry and the American Academy of Clinical Psychiatrists.

While there is clear evidence that cannabis use relative to the general population “is more prevalent among patients with psychiatric disorders,” it is less certain how often this use is risky, said Diana M. Martinez, MD, professor of psychiatry at Columbia University in New York.

Independent of euphoric effects, cannabis can be perceived by individuals with psychiatric diagnosis as self-medication for feelings of stress, social anxiety, and insomnia, among other symptoms. These are the same reasons why many individuals without psychiatric conditions use cannabis-containing products.

The perception that cannabis use is generally benign presumably explains the successful efforts at legalization, but there are risks for those with or without psychiatric illnesses, Dr. Martinez pointed out at the meeting, sponsored by Medscape Live. Not least, about 20% of regular users of cannabis develop cannabis use disorder (CUD), a condition defined in the DSM-5 as the continued use of cannabis despite adverse consequences, such as dependence.
 

Impact of severe CUD ‘incapacitating’

“Of those who meet criteria for CUD, 23% have severe CUD, which is an incapacitating form,” reported Dr. Martinez, citing work led by Deborah Hasin, PhD, professor of clinical epidemiology at Columbia University.

However, relative to otherwise healthy individuals, those with a psychiatric diagnosis might face greater benefits or greater risks from cannabis use, according to Dr. Martinez, who cited a 2017 report from the National Academies of Science, Engineering, and Medicine (NASEM).

This report evaluated the potential risks and benefits on the basis of published studies.

There is limited evidence that regular cannabis increases rather than modifies symptoms of mania and hypomania in patients with bipolar disorder, according to the report. The report also cited limited evidence that cannabis use increases severity of posttraumatic stress disorder (PTSD). There was limited evidence of adverse effects on symptoms of anxiety, although this appeared to depend on daily or nearly daily use.

The report found no data of acceptable quality to draw conclusions about the effect of cannabis use on symptoms of depression.

In patients with attention-deficit/hyperactivity disorder (ADHD), “a recent study showed that daily but not occasional use of cannabis increased impulsivity but not inattention, working memory, or verbal intelligence,” said Dr. Martinez, citing a study published this year.

Some evidence also suggests that patients with a psychiatric disorder might benefit from cannabis use, but, again, this evidence is limited. For one example, it includes a potential reduction in symptoms of obsessive-compulsive disorder, Dr. Martinez said.
 

More support for cannabis in medical disease

Relative to the quality of evidence supporting benefit from cannabis in psychiatric disease, the data appear to be stronger for patients with medical illnesses, such as cancer. For example, Dr. Martinez cited evidence that tetrahydrocannabinol (THC), a major active ingredient in cannabis, improves sleep in the context of a medical illnesses. There is also evidence for anxiolytic effects in patients with a medical illness, although that is weaker.

In patients with or without a psychiatric disorder, marijuana does pose a risk of substance abuse disorder, and it shares the risks of intoxicants, such as inattention leading to increased risk of accidents, including motor vehicle accidents. This pertains to those with or without a psychiatric or medical condition, Dr. Martinez said.

While intermittent light use of cannabis appears to pose no risk or a very low risk of long-term adverse effects on cognition, at least in patients without psychiatric disorders, Dr. Martinez indicated that the risk-benefit ratio for any individual is use dependent. The risk of CUD, for example, increases with the frequency of exposure and the potency of the cannabis. Dr. Martinez indicated that a conservative approach is prudent with the limited evidence available for patients with psychiatric disorders.
 

Empirical evidence for therapeutic role

In published studies, other researchers have expressed interest in a potential therapeutic role of cannabis for psychiatric disorders, but there appears to be a general consensus that the supportive data remain weak. One expert who has written on this topic, Jerome Sarris, PhD, professor of integrative mental health, NICM Health Research Institute, Western Sydney University, Westmead, Australia, said that empirical evidence does support a benefit in selected patients.

“Of course, high THC forms are strongly discouraged in people with schizophrenia or high risk of developing psychotic disorder, or in youths,” Dr. Sarris explained. “However, there is a potential role for use in people with sleep and pain issues, and many find it beneficial to also assist with affective disorder symptoms.”

In a systematic review he led that was published last year, the evidence to support cannabis for psychiatric disorders was characterized as “embryonic.” However, small studies and case reports appear to support benefit for such indications as ADHD if precautions are taken.

“I certainly would not discourage use of prescribed standardized medicinal cannabis therapeutics for all people with psychiatric disorders,” Dr. Sarris said. He suggested that attention should be made to the THC potency and terpene composition of the products that patients with psychiatric disorders are taking.

The benefits of Pfizer’s COVID-19 vaccine for children ages 5 to 11 outweigh its risks, according to an independent panel of vaccine experts that advises the Food and Drug Administration (FDA).
 

Seventeen of the 18 members of the Vaccines and Related Biological Products Advisory Committee (VRBPAC) on Oct. 26 voted to recommend the 10-microgram shot for kids, which is one-third the dose given to adults.

One member, Michael Kurilla, MD, director of the division of clinical innovation at the National Institutes of Health, Bethesda, Md., abstained from voting.

If the FDA follows the recommendation, as it typically does, and issues an Emergency Use Authorization for the vaccine, the shots could be available within days.

After the FDA’s final decision, the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices will meet to make specific recommendations for its use. The CDC committee must stick closely to the conditions for use spelled out in the EUA, so their recommendations are likely to be similar to those made by the FDA. Their next meeting is scheduled for Nov. 2 and 3.

In the end, some on the panel felt uneasy with their decision.

“I voted yes primarily because I wanted to make sure that children who really need this vaccine, the Black and brown children of our country, get the vaccine,” said James Hildreth, MD, PhD, president and CEO of Meharry Medical College in Nashville.

“But to be honest, the best way to protect the health of some children will be to do nothing because they will be just fine,” he said.

Others said they were surprised by how difficult the decision had been.

“This is a much tougher one than we had expected going into it,” said committee member Eric Rubin, MD, editor and chief of the New England Journal of Medicine, during the FDA advisory committee’s meeting.

Ahead of the vote, the committee heard presentations outlining the expected benefits of vaccinating children along with potential risks.

“Children have been greatly impacted by the pandemic,” said Fiona Havers, MD, a medical officer with the CDC in Atlanta who reviewed the epidemiology of COVID-19 in kids.

In the second year of the pandemic, as more seniors have been vaccinated against the virus, COVID cases have largely shifted from older to younger age groups.

So far, there have been more than 1.9 million COVID-19 cases in children ages 5 through 11 in the United States.. Cases in kids saw a big jump in July and August with summer travel, schools reopening, and the dominance of the Delta variant.

And those are just the cases reported to the CDC. Regular testing of anonymous blood samples collected at sites across the United States indicates that 6 times as many kids have had COVID than what is reflected in official counts.

Last winter, blood sample testing showed about 13% of children had antibodies against the virus, suggesting they’d been infected. By this summer, that number had risen to 42%.

That figure clearly made an impression on many members of the committee who asked the FDA’s vaccine reviewers if they had tried to account for immunity from past infections in their modeling. They had not.

Some felt that even with a highly effective vaccine — new data presented by Pfizer showed the children’s dose was 90% effective at preventing symptomatic infections in kids — caution was warranted as much is still unknown about myocarditis, a rare side effect of the mRNA vaccines.

Myocarditis has been more common in younger age groups. It usually goes away over time but requires hospital care. It’s not known if myocarditis could have lingering effects for those who experience it.

There were no cases of myocarditis seen in Pfizer’s studies of the vaccine in children, and no other serious events were seen. Vaccine side effects reported in the Pfizer studies were mostly mild and included fatigue, headache, and pain at the injection site.

“We think we have optimized the immune response and minimized our reactions,” said William Gruber, MD, senior vice president vaccine research and clinical development at Pfizer.

But the studies didn’t include enough participants to pick up rare, but serious adverse events like myocarditis.

“We’re worried about a side effect that we can’t measure yet, but it’s probably real, and we see a benefit that isn’t the same as it is in older age groups,” said Dr. Rubin.

Benefits vs. risks

FDA modeled the benefits and risks for children under a variety of scenarios. The benefits of the vaccines to children very much depend on the amount of transmission in the community.

When transmission is high, the benefits to children — in terms of infections, hospitalizations, ICU admissions — clearly outweigh its risks.

But when COVID-19 rates are low in the community, as they were in June, FDA analysts predicted the vaccines might send more children to the hospital for myocarditis than the virus would.

The FDA noted that kids who are hospitalized for myocarditis tend not to be as ill as children with COVID-19, however.

“If the trends continue the way they are going, the emergency for children is not what we might think it would be. That was my concern,” Dr. Hildreth said.

But others warned against complacency.

“Thinking that this is going to be the end of the wave permanently may be a little overly optimistic,” said committee chairman Arnold Monto, MD, a professor of public health and epidemiology at the University of Michigan, Ann Arbor.

The majority of COVID-19 cases in children are mild. Only about 1% of kids are hospitalized for their infections, according to CDC data. But the rates of hospitalizations in kids are about 3 times higher for people of color — including Blacks, Hispanics, and Native Americans, as compared to Whites and Asian Americans.

Since the start of the pandemic, 94 children ages 5 to 11 have died, making it the eighth leading cause of death for kids this age last year.

More than 5,200 children have developed a delayed complication from their infections called Multi-System Inflammatory Syndrome (MIS-C).

MIS-C can be severe and require hospital care and can lead to myocarditis. Children ages 5 to 11 are the age group at greatest risk for this complication.

Kids can also get long COVID. There’s not a lot of data on how often this happens, though it appears to be less frequent in children than in adults.

But a survey in the United Kingdom found that 7%-8% of kids have symptoms from their infections that last longer than 12 weeks, Dr. Havers said. Symptoms that can linger for kids include fatigue, cough, muscle and joint pain, headaches, and insomnia.

More than 1 million children have been impacted by school closures so far this year, and quarantines have had lasting impacts on learning, social development, and mental health.

Even though kids aren’t usually COVID superspreaders, they can still pass the infection on to others.

“What is clear is that secondary transmission from children, both to other children and to adults, does occur,” Dr. Havers said.

For that reason, they can continue the spread of the virus and give it opportunities to mutate and become more dangerous.

Safety monitoring to continue

Some committee members referenced thousands of letters they had received within the past few days urging them to vote against the vaccine.

Jay Portnoy, MD, a professor of pediatrics at Children’s Mercy Hospital in Kansas City, Mo., said he had personally received about 4,000 emails.

“But I feel like I need to also represent the consumers, the parents that I see every day in the clinic who are terrified of sending their children to school because they’re not protected against COVID,” he said, explaining his vote to recommend authorization.

“Our kids are going to be dealing with this virus for many years to come. It’s going to come repeatedly. Getting this vaccine is just the first step that they can take to protect themselves from having bad outcomes,” Dr. Portnoy said.

Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, reminded members of the committee that there were several government surveillance systems in place to catch any potential safety issues in near real time.

“I really appreciate very much the concern here. The safety monitoring of this vaccine will continue,” Dr. Marks said. “I do view this as one of our greatest responsibilities.”

“I really am so grateful that we had this discussion and voted to approve,” said Capt. Amanda Cohn, MD, chief medical officer at the National Center for Immunization and Respiratory Diseases.

“I think the benefits in this age group really are super important even if they are lower than for other age groups.”

Some felt that even with a highly effective vaccine — new data presented by Pfizer showed the children’s dose was 90% effective at preventing symptomatic infections in kids — caution was warranted as much is still unknown about myocarditis, a rare side effect of the mRNA vaccines.

Myocarditis has been more common in younger age groups. It usually goes away over time but requires hospital care. It’s not known if myocarditis could have lingering effects for those who experience it.

There were no cases of myocarditis seen in Pfizer’s studies of the vaccine in children, and no other serious events were seen. Vaccine side effects reported in the Pfizer studies were mostly mild and included fatigue, headache, and pain at the injection site.

“We think we have optimized the immune response and minimized our reactions,” said William Gruber, MD, senior vice president vaccine research and clinical development at Pfizer.

But the studies didn’t include enough participants to pick up rare, but serious adverse events like myocarditis.

“We’re worried about a side effect that we can’t measure yet, but it’s probably real, and we see a benefit that isn’t the same as it is in older age groups,” said Dr. Rubin.

Benefits vs. risks

FDA modeled the benefits and risks for children under a variety of scenarios. The benefits of the vaccines to children very much depend on the amount of transmission in the community.

When transmission is high, the benefits to children — in terms of infections, hospitalizations, ICU admissions — clearly outweigh its risks.

But when COVID-19 rates are low in the community, as they were in June, FDA analysts predicted the vaccines might send more children to the hospital for myocarditis than the virus would.

The FDA noted that kids who are hospitalized for myocarditis tend not to be as ill as children with COVID-19, however.

“If the trends continue the way they are going, the emergency for children is not what we might think it would be. That was my concern,” Dr. Hildreth said.

But others warned against complacency.

“Thinking that this is going to be the end of the wave permanently may be a little overly optimistic,” said committee chairman Arnold Monto, MD, a professor of public health and epidemiology at the University of Michigan, Ann Arbor.

The majority of COVID-19 cases in children are mild. Only about 1% of kids are hospitalized for their infections, according to CDC data. But the rates of hospitalizations in kids are about 3 times higher for people of color — including Blacks, Hispanics, and Native Americans, as compared to Whites and Asian Americans.

Since the start of the pandemic, 94 children ages 5 to 11 have died, making it the eighth leading cause of death for kids this age last year.

More than 5,200 children have developed a delayed complication from their infections called Multi-System Inflammatory Syndrome (MIS-C).

MIS-C can be severe and require hospital care and can lead to myocarditis. Children ages 5 to 11 are the age group at greatest risk for this complication.

Kids can also get long COVID. There’s not a lot of data on how often this happens, though it appears to be less frequent in children than in adults.

But a survey in the United Kingdom found that 7%-8% of kids have symptoms from their infections that last longer than 12 weeks, Dr. Havers said. Symptoms that can linger for kids include fatigue, cough, muscle and joint pain, headaches, and insomnia.

More than 1 million children have been impacted by school closures so far this year, and quarantines have had lasting impacts on learning, social development, and mental health.

Even though kids aren’t usually COVID superspreaders, they can still pass the infection on to others.

“What is clear is that secondary transmission from children, both to other children and to adults, does occur,” Dr. Havers said.

For that reason, they can continue the spread of the virus and give it opportunities to mutate and become more dangerous.

Safety monitoring to continue

Some committee members referenced thousands of letters they had received within the past few days urging them to vote against the vaccine.

Jay Portnoy, MD, a professor of pediatrics at Children’s Mercy Hospital in Kansas City, Mo., said he had personally received about 4,000 emails.

“But I feel like I need to also represent the consumers, the parents that I see every day in the clinic who are terrified of sending their children to school because they’re not protected against COVID,” he said, explaining his vote to recommend authorization.

“Our kids are going to be dealing with this virus for many years to come. It’s going to come repeatedly. Getting this vaccine is just the first step that they can take to protect themselves from having bad outcomes,” Dr. Portnoy said.

Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, reminded members of the committee that there were several government surveillance systems in place to catch any potential safety issues in near real time.

“I really appreciate very much the concern here. The safety monitoring of this vaccine will continue,” Dr. Marks said. “I do view this as one of our greatest responsibilities.”

“I really am so grateful that we had this discussion and voted to approve,” said Capt. Amanda Cohn, MD, chief medical officer at the National Center for Immunization and Respiratory Diseases.

“I think the benefits in this age group really are super important even if they are lower than for other age groups.”

Sleeping too much or too little can lead to cognitive decline over time, but new research suggests there could be a sleep time “sweet spot” that stabilizes cognitive function.

In a longitudinal study, investigators found older adults who slept less than 4.5 hours or more than 6.5 hours a night reported significant cognitive decline over time, but cognitive scores for those with sleep duration in between that range remained stable.

“This really suggests that there’s this middle range, a ‘sweet spot,’ where your sleep is really optimal,” said lead author Brendan Lucey, MD, MSCI, associate professor of neurology and director of the Washington University Sleep Medicine Center, St. Louis.

The study, published online Oct. 20 in Brain, is part of a growing body of research that seeks to determine if sleep can be used as a marker of Alzheimer’s disease progression.
 

A complex relationship

Studies suggest a strong relationship between sleep patterns and Alzheimer’s disease, which affects nearly 6 million Americans. The challenge, Dr. Lucey said, is unwinding the complex links between sleep, Alzheimer’s disease, and cognitive function.

An earlier study by Dr. Lucey and colleagues found that poor sleep quality is associated with early signs of Alzheimer’s disease, and a report published in September found that elderly people who slept less than 6 hours a night had a greater burden of amyloid beta, a hallmark sign of Alzheimer’s disease.

For this new study, researchers monitored sleep-wake activity over 4-6 nights in 100 participants who underwent annual cognitive assessments and clinical studies, including APOE genotyping, as part of a longitudinal study at the Knight Alzheimer Disease Research Center at Washington University. Participants also provided cerebrospinal fluid (CSF) total tau and amyloid-beta42 and wore a small EEG device on their forehead while they slept.

The majority of participants had a clinical dementia rating (CDR) score of 0, indicating no cognitive impairment. Twelve individuals had a CDR >0, with most reporting mild cognitive impairment.

As expected, CSF analysis showed greater evidence of Alzheimer’s disease pathology in those with a baseline CDR greater than 0.

Changes in cognitive function were measured using a Preclinical Alzheimer Cognitive Composite (PACC) score, a composite of results from a neuropsychological testing battery that included the Free and Cued Selective Reminding Test, the Logical Memory Delayed Recall Test from the Wechsler Memory Scale-Revised, the Digit Symbol Substitution Test from the Wechsler Adult Intelligence Scale-Revised, and the Mini-Mental State Examination.

Researchers found an upside-down U-shaped relationship between PACC scores and sleep duration, with dramatic cognitive decline in those who slept less than 4.5 hours or more than 6.5 hours a night (P < .001 for both). The U-shaped relationship was also found with measures of sleep phases, including time spent in rapid eye movement and in non-REM sleep (P < .001 for both).

The findings persisted even after controlling for confounders that can affect sleep and cognition, such as age, CSF total tau/amyloid-beta-42 ratio, APOE ε4 allele carrier status, years of education, and sex.

Understanding how sleep changes at different stages of Alzheimer’s disease could help researchers determine if sleep can be used as a marker of disease progression, Dr. Lucey said. That could lead to interventions to slow that process.

“We’re not at the point yet where we can say that we need to monitor someone’s sleep time and then do an intervention to see if it would improve their risk for cognitive decline,” said Dr. Lucey, who plans to repeat this sleep study with the same cohort to track changes in sleep patterns and cognitive function over time. “But that’s a question I’m very excited to try to answer.”
 

A component of cognitive health

Commenting on the findings, Heather Snyder, PhD, vice president of medical and scientific relations for the Alzheimer’s Association, noted that the study adds to a body of evidence linking sleep and cognition, especially how sleep quality can optimize brain function.

“We’ve seen previous research that’s shown poor sleep contributes to dementia risk, as well as research showing sleep duration may play a role in cognition,” she said.

“We also need studies that look at sleep as an intervention for cognitive health,” Dr. Snyder said. “Sleep is an important aspect of our overall health. Clinicians should have conversations with their patients about sleep as part of standard discussions about their health habits and wellness.”

The study was funded by the National Institutes of Health, the American Sleep Medicine Foundation, the Roger and Paula Riney Fund, and the Daniel J. Brennan, MD Fund. Dr. Lucey consults for Merck and Eli Lilly. Dr. Snyder has disclosed no relevant financial relationships. Full disclosures are included in the original article.

People who don’t get vaccinated against COVID-19 should expect to be reinfected with the coronavirus every 16 to 17 months on average, according to a recent study published in The Lancet Microbe.

Since COVID-19 hasn’t existed for long enough to perform a long-term study, researchers at Yale University and the University of North Carolina at Charlotte looked at reinfection data for six other human-infecting coronaviruses, including SARS and MERS.

“Reinfection can reasonably happen in three months or less,” Jeffrey Townsend, PhD, lead study author and a biostatistics professor at the Yale School of Public Health, said in a statement.

“Therefore, those who have been naturally infected should get vaccinated,” he said. “Previous infection alone can offer very little long-term protection against subsequent infections.”

The research team looked at post-infection data for six coronaviruses between 1984-2020 and found reinfection ranged from 128 days to 28 years. They calculated that reinfection with COVID-19 would likely occur between 3 months to 5 years after peak antibody response, with an average of 16 months. This is less than half the duration seen for other coronaviruses that circulate among humans.

The risk of COVID-19 reinfection is about 5% at three months, which jumps to 50% after 17 months, the research team found. Reinfection could become increasingly common as immunity wanes and new variants develop, they said.

“We tend to think about immunity as being immune or not immune. Our study cautions that we instead should be more focused on the risk of reinfection through time,” Alex Dornburg, PhD, senior study author and assistant professor of bioinformatics and genomics at UNC, said in the statement.

“As new variants arise, previous immune responses become less effective at combating the virus,” he said. “Those who were naturally infected early in the pandemic are increasingly likely to become reinfected in the near future.”

Study estimates are based on average times of declining immunity across different coronaviruses, the researchers told the Yale Daily News. At the individual level, people have different levels of immunity, which can provide shorter or longer duration of protection based on immune status, immunity within a community, age, underlying health conditions, environmental exposure, and other factors.

The research team said that preventive health measures and global distribution of vaccines will be “critical” in minimizing reinfection and COVID-19 deaths. In areas with low vaccination rates, for instance, unvaccinated people should continue safety practices such as social distancing, wearing masks, and proper indoor ventilation to avoid reinfection.

“We need to be very aware of the fact that this disease is likely to be circulating over the long term and that we don’t have this long-term immunity that many people seem to be hoping to rely on in order to protect them from disease,” Dr. Townsend told the newspaper.

The popular antipsychotic quetiapine (Seroquel) seems to calm patients with multiple sclerosis (MS) who develop psychiatric distress after taking corticosteroids, a new case review says.

“Our case-report study observed that quetiapine was effective at decreasing irritability, reducing psychological distress, and improving sleep in patients with MS who experienced psychosis symptoms compared with patients who received no treatment. This has changed our practice as we now counsel all patients about the potential side effect of steroid-induced psychosis and discuss treatment options,” said Olinka Hrebicek, MD, medical director of Vancouver Island Multiple Sclerosis Clinic in Victoria, B.C., who was scheduled to present the study findings at the 2021 Annual Meeting of the Consortium of Multiple Sclerosis Centers (CMSC).

According to Dr. Hrebicek, who spoke in an interview, nursing staff and neurologists at the Canadian clinic had typically attributed symptoms such as irritability, anger, insomnia, and psychological distress to the stress of experiencing a relapse. The treatment often was a prescription for a benzodiazepine or zopiclone.

In fact, she and colleagues wrote in their report, psychosis following treatment with high-dose corticosteroids for MS may be underreported.

“The purpose of the study was to determine whether quetiapine was effective for treating symptoms of steroid-induced psychosis in patients with MS,” study coauthor and clinic research assistant Niall Murphy said in an interview. “We also wanted to highlight the importance of looking for symptoms of steroid-induced psychosis as this is likely not the primary concern when treating patients for a relapse. In addition, nurses and neurologists may have less experience with the spectrum of clinical symptoms of psychosis than psychiatrists.”

For the case review, researchers examined 10 reports (8 female) of patients who had signs of psychiatric distress after treatment with steroids. Eight of the patients were treated with quetiapine (six female, two male).

All those who took quetiapine experienced benefits, while the two others didn’t improve.

Commenting on the study, E. Sherwood Brown, MD, PhD, MBA, professor of psychiatry at the University of Texas Southwestern Medical Center, Dallas, said in an interview that psychosis may not appear as expected in patients who develop it as a result of corticosteroid use. “Typically, psychosis refers to delusions, hallucinations, or disorganized thought processes. However, with corticosteroids severe mood and cognitive changes [for example, delirium] are also often included in the definition. Mild mood and memory changes appear to be fairly common with prescription corticosteroids. More severe symptoms are less common.”

Higher doses of corticosteroids – like those used in MS – boost the risk of psychosis, said Dr. Brown, who was not involved in the study.

As for quetiapine, Dr. Brown said it could be a good treatment option. “The use of quetiapine, a drug approved for schizophrenia and mania, is consistent with the idea suggested in the literature that the symptoms with corticosteroids tend to be similar to those of bipolar disorder and that they respond to medications for bipolar disorder,” he said. “A potential concern is that both corticosteroids and quetiapine can cause weight gain. However, this may not be a major problem with a brief course of the corticosteroids. It would be great to see a randomized, controlled trial.”

In British Columbia, the Victoria clinic has changed policy as a result of the analysis, Dr. Hrebicek said. “Nurses and physicians now ask more specific questions to decide if patients are experiencing symptoms of steroid-induced psychosis and whether they should be treated with an antipsychotic medication.”

And now, report coauthor Mr. Murphy said, “our clinic proactively offers patients a prescription for quetiapine that they can fill if they are experiencing symptoms of steroid psychosis.”

Dr. Brown supported the new policy of alerting patients to the psychosis risk. “Counseling patients about common side effects is a good idea,” he said. “I have seen data suggesting that patients may be hesitant to report psychiatric symptoms with corticosteroids to their physicians. Letting them know about the potential for these kinds of side effects might make them more forthcoming in reporting this side effect.”

No study funding is reported. The study authors reported no disclosures. Dr. Brown has a National Institutes of Health grant for studying the effect of corticosteroids on the brain.

In British Columbia, the Victoria clinic has changed policy as a result of the analysis, Dr. Hrebicek said. “Nurses and physicians now ask more specific questions to decide if patients are experiencing symptoms of steroid-induced psychosis and whether they should be treated with an antipsychotic medication.”

And now, report coauthor Mr. Murphy said, “our clinic proactively offers patients a prescription for quetiapine that they can fill if they are experiencing symptoms of steroid psychosis.”

Dr. Brown supported the new policy of alerting patients to the psychosis risk. “Counseling patients about common side effects is a good idea,” he said. “I have seen data suggesting that patients may be hesitant to report psychiatric symptoms with corticosteroids to their physicians. Letting them know about the potential for these kinds of side effects might make them more forthcoming in reporting this side effect.”

The popular antipsychotic quetiapine (Seroquel) seems to calm patients with multiple sclerosis (MS) who develop psychiatric distress after taking corticosteroids, a new case review says.

“Our case-report study observed that quetiapine was effective at decreasing irritability, reducing psychological distress, and improving sleep in patients with MS who experienced psychosis symptoms compared with patients who received no treatment. This has changed our practice as we now counsel all patients about the potential side effect of steroid-induced psychosis and discuss treatment options,” said Olinka Hrebicek, MD, medical director of Vancouver Island Multiple Sclerosis Clinic in Victoria, B.C., who was scheduled to present the study findings at the 2021 Annual Meeting of the Consortium of Multiple Sclerosis Centers (CMSC).

According to Dr. Hrebicek, who spoke in an interview, nursing staff and neurologists at the Canadian clinic had typically attributed symptoms such as irritability, anger, insomnia, and psychological distress to the stress of experiencing a relapse. The treatment often was a prescription for a benzodiazepine or zopiclone.

In fact, she and colleagues wrote in their report, psychosis following treatment with high-dose corticosteroids for MS may be underreported.

“The purpose of the study was to determine whether quetiapine was effective for treating symptoms of steroid-induced psychosis in patients with MS,” study coauthor and clinic research assistant Niall Murphy said in an interview. “We also wanted to highlight the importance of looking for symptoms of steroid-induced psychosis as this is likely not the primary concern when treating patients for a relapse. In addition, nurses and neurologists may have less experience with the spectrum of clinical symptoms of psychosis than psychiatrists.”

For the case review, researchers examined 10 reports (8 female) of patients who had signs of psychiatric distress after treatment with steroids. Eight of the patients were treated with quetiapine (six female, two male).

All those who took quetiapine experienced benefits, while the two others didn’t improve.

Commenting on the study, E. Sherwood Brown, MD, PhD, MBA, professor of psychiatry at the University of Texas Southwestern Medical Center, Dallas, said in an interview that psychosis may not appear as expected in patients who develop it as a result of corticosteroid use. “Typically, psychosis refers to delusions, hallucinations, or disorganized thought processes. However, with corticosteroids severe mood and cognitive changes [for example, delirium] are also often included in the definition. Mild mood and memory changes appear to be fairly common with prescription corticosteroids. More severe symptoms are less common.”

Higher doses of corticosteroids – like those used in MS – boost the risk of psychosis, said Dr. Brown, who was not involved in the study.

As for quetiapine, Dr. Brown said it could be a good treatment option. “The use of quetiapine, a drug approved for schizophrenia and mania, is consistent with the idea suggested in the literature that the symptoms with corticosteroids tend to be similar to those of bipolar disorder and that they respond to medications for bipolar disorder,” he said. “A potential concern is that both corticosteroids and quetiapine can cause weight gain.

Several antiepileptic drugs (AEDs) are associated with an increased risk for priapism, new research suggests.

After analyzing U.S. adverse event reporting data, investigators found that among nearly 200 cases of priapism, a persistent, often painful erection unrelated to sexual interest or stimulation that lasts more than 4 hours, eight AEDs were associated with a positive “safety signal” for priapism.

These included valpromide, brivaracetam, valproic acid, topiramate, oxcarbazepine, clonazepam, levetiracetam, and carbamazepine. Of these, valpromide had the largest association.

“Based on our results, we would recommend to clinicians to be cautious about the possibility of encountering priapism” in patients receiving the eight AEDs identified, lead researcher Ana Pejcic, PhD, department of pharmacology and toxicology, University of Kragujevac, Serbia, told meeting attendees.

If clinicians encounter such cases, they should be “reported to the regulatory authorities,” Dr. Pejcic added.

The findings were presented at the virtual congress of the European College of Neuropsychopharmacology.
 

Noteworthy limitations

Dr. Pejcic told this news organization that the safety signal with AEDs “does not directly mean that a medicine has caused the reported adverse event” because an illness or other drug taken by the patient could be responsible instead.

She also noted that the U.S. Food and Drug Administration’s Adverse Event Reporting System relies on “spontaneous reports of adverse events,” which have multiple limitations.

These limitations include that the FDA “does not require that a causal relationship between a drug and event be proven, and reports do not always have enough information to properly evaluate an event.”

Nevertheless, Dr. Pejcic added that if a causal relationship was to be shown, the underlying mechanism could be linked to the pharmacological properties of the individual antiepileptic, such as altered alpha-1 adrenergic receptor expression or increased dopamine release.

Still, that would require “further evaluation in larger pharmacoepidemiological studies, with adjustment for potential confounding variables,” she said.
 

Replication needed

Priapism has recently been observed in case reports in association with the use of some AEDs. In addition, use of the drugs has been associated with hypo- and hypersexuality, as well as erectile and ejaculatory dysfunction.

Because the relationship between priapism and AED use “has not been well characterized,” the researchers mined data from the FDA’s Adverse Event Reporting System.

They examined entries from the first quarter of 2004 and the third quarter of 2020, focusing on 47 AEDs from the N03A subgroup of the Anatomical Therapeutic Chemical Classification System.

The researchers identified 8,122,037 cases for data analysis, of which 1,936 involved priapism as an adverse event. In total, 16 antiepileptic medications had at least one case of an adverse event involving priapism.

A positive safety signal was defined as a Proportional Reporting Ratio (PRR) of at least two, a chi-squared of at least four, or three or more cases. The signal was detected for valpromide, brivaracetam, valproic acid, topiramate, oxcarbazepine, clonazepam, levetiracetam, and carbamazepine.

The largest association with priapism was with valpromide, at a PRR of 61.79. That was followed by PRR of 9.61 for brivaracetam, 7.28 for valproic acid, and 3.23 for topiramate.

“Considering that the proportionality analysis we applied in our study is used for hypothesis generation, our results will need to confirm in large cohorts and case-control studies,” said Dr. Pejcic.
 

New and important hypothesis?

Commenting on the study, Daniel Goldenholz, MD, PhD, instructor in the Division of Epilepsy, Beth Israel Deaconess Medical Center, Boston, said priapism is not something that practicing epileptologists are instructed “to look for.”

He noted that “the idea of looking for a hidden signal in a massive database like this is very appealing” because it could reveal patterns that were previously undetected.

However, the event rate in the study suggests priapism, which “in the right context would be considered a medical emergency, [is] relatively uncommon,” said Dr. Goldenholz, who was not involved with the research.

He noted that medications that could cause priapism, “such as antidepressants, blood pressure meds, and anticoagulants,” are commonly used by many people – including those with epilepsy.

It is consequently possible that “the finding from this study can be explained by comorbid medical problems,” Dr. Goldenholz said. This is particularly likely because many of the AEDs in question “have been on the market for decades,” he added.

“If a seemingly dangerous symptom would be happening as a result of one of these medications, it is quite surprising that it has not been noticed sooner,” he said.

Still, Dr. Goldenholz noted that it is “possible that these authors have a new and important hypothesis which must now be tested: Does priapism occur in patients with antiseizure medications when other causes are already ruled out?”

The investigators and Dr. Goldenholz have disclosed no relevant financial relationships.

Near-infrared light delivered to the brain using a specially designed helmet appears to improve memory, motor function, and processing skills in cognitively healthy older adults, in new findings that suggest potential benefit in patients with dementia.

Studies in animals and people have shown “many positive effects” with near-infrared transcranial photobiomodulation therapy (PBM-T), study investigator Paul Chazot, PhD, department of biosciences, Durham University, United Kingdom, told this news organization.

For example, PBM-T has been shown to increase blood circulation (which keeps the brain well oxygenated), boost mitochondria function in neurons, protect neurons from oxidative stress, and help maintain neuronal connectivity, Dr. Chazot explained.

PBM-T has also been shown to reduce amyloid and phosphorylated tau load, pathological signs of Alzheimer’s disease.

“All these in combination improve memory performance and mobility,” Dr. Chazot said.

The study was published online October 18 in Photobiomodulation, Photomedicine and Laser Surgery. 
 

Promising early data

In the study, 14 healthy adults, aged 45 to 70 years, received 6 minutes of transcranial PBM-T twice daily at a wavelength of 1,068 nanometers over 4 weeks. PBM-T was delivered via a helmet that comprised 14 air-cooled light emitting diode panel arrays. A control group of 13 adults used a sham PBM-T helmet.

Before and after active and sham treatment, all participants completed the automated neuropsychological assessment metrics (ANAM) – a computer-based tool designed to detect speed and accuracy of attention, memory, and thinking ability.

According to the research team, compared with sham PBM-T, those receiving active PBM-T showed significant improvement in motor function (finger tapping), working memory, delayed memory, and brain processing speed, the research team reports. No adverse effects were reported.

“This study complements our other recent studies, which showed improvement in memory performance with no obvious side effects,” said Dr. Chazot.

“While this is a pilot study and more research is needed, there are promising indications that therapy involving infrared light might also be beneficial for people living with dementia, and this is worth exploring,” Dr. Chazot added in a news release.

The PBM-T helmet was devised by first author Gordon Dougal, MBChB, of Maculume in the U.K., and a general practitioner based in Durham.

A recent study by Mr. Dougal, Dr. Chazot, and collaborators in the United States provides early evidence that PBM-T can improve memory in adults with dementia.

In that study, 39 patients received 6 minutes of PBM-T twice a day for 8 weeks, alongside a control group of 17 patients who received sham PBM-T.

After 8 weeks, there was about a 20% improvement in Mini-Mental State Exam (MMSE) scores in the active PBM-T group compared with roughly a 6% improvement in the control group, the researchers report in the journal Cureus.
 

More research needed

Reached for comment, Rebecca Edelmayer, PhD, Alzheimer’s Association senior director of scientific engagement, said using light to stimulate the brain is “an emerging technology.”

“However, this is a very small study in healthy volunteers, therefore we don’t know from this work alone if this approach would work as an intervention or reduce [the] risk of cognitive decline,” Dr. Edelmayer told this news organization.

“That being said, we’re starting to see companies looking at similar, noninvasive methods of stimulating the brain. For example, brain stimulation devices have been applied to other neurodegenerative diseases like Parkinson’s to try to prevent degeneration of brain cells,” Dr. Edelmayer noted. 

She said more research is needed to understand how photobiomodulation might be used as a therapy or prevention for cognitive decline and dementia.

“Specifically, we need to understand what parts of the brain need to be targeted and at what point(s) in the disease course this treatment would be most impactful. If proven to be effective, this could possibly be part of an approach that’s combined with other treatments, like drugs and lifestyle interventions,” said Dr. Edelmayer.

The Alzheimer’s Association is funding a number of projects looking at noninvasive treatments for Alzheimer’s disease, including two clinical trials looking at deep brain stimulation and photobiomodulation.

Maculume provided funding for the study. Mr. Dougal is a majority shareholder in the company, which manufactures the helmet device used in the study. Dr. Chazot, study co-authors, and Dr. Edelmayer have disclosed no relevant financial relationships.
