Attention deficit disorder (ADD), with or without hyperactivity, affects up to 5 percent of the population, according to the DSM-5. It can be difficult to diagnose behaviorally, and coexisting conditions like autism spectrum disorder or mood disorders can mask it.
While recent MRI studies have indicated differences in the brains of people with ADD, the differences are too subtle and MRI too expensive to be a practical diagnostic measure. But new research suggests a role for an everyday, relatively cheap alternative: electroencephalography (EEG). …
Anxiety disorders are the most common mental illness in the U.S., but lack an ideal treatment. The current drugs, SSRIs and benzodiazepines, have many side effects. More recently developed treatments seek to block corticotropin-releasing hormone (CRH), the classic stress hormone that activates our “fight or flight” response; in people with anxiety, CRH gets activated at the wrong time or too intensely.
But in clinical trials, results have been disappointing: of the eight completed phase II and III trials of CRH antagonists for depression or anxiety, six have been published, with largely negative findings, says Joseph Majzoub, MD, of the Division of Endocrinology at Boston Children’s Hospital.
Rong Zhang, PhD, who works in Majzoub’s research lab, had a hunch that blocking CRH throughout the brain, as was done in these trials, isn’t the best approach. “Blocking CRH receptors all over the brain doesn’t work,” she says. “We think the effects work against each other somehow. It may be that CRH has different effects depending on where in the brain it is produced.”
Today in Molecular Psychiatry, Zhang, Majzoub and colleagues demonstrate that certain neurons in the hypothalamus play a central, previously unknown role in triggering anxiety. When they used genetic tricks to selectively remove the CRH gene from about 1,000 of these neurons in mice, the effect was startling — they erased the animals’ natural fears. …
More than 100,000 smartphone apps are currently categorized as “health apps.” There are apps for physical health—apps that log work-outs, track nutritional intake, and monitor sleeping patterns. And there are apps for mental health—apps that identify your mood, guide meditation and alleviate depression. But can an app tackle a public health problem as serious as teen suicide?
Turns out, mobile phones and suicide prevention may not be such strange bedfellows.
Elizabeth Wharff, PhD, and Kimberly O’Brien, PhD, clinician-researchers from the Department of Psychiatry at Boston Children’s Hospital, specialize in working with adolescents who struggle with suicidal thoughts. Noting that teens are already turning to their phones whenever they need something, they believe a mobile app may be the perfect platform to support them through tough times. Wharff feels that existing apps designed to help with depression and anxiety lack something crucial: parent mode.
Can a robotic talking bear have therapeutic value? “The Bear,” part of a New York Times video series called Robotica, offers a glimpse of Huggable’s potential when Beatrice Lipp, a child with a chronic medical condition, visits the hospital, nervous about what’s to come.
“We want to offer kids one more way of helping them to feel OK where they are in what’s otherwise a really stressful experience,” explains Dierdre Logan, PhD, director of Psychological Services for Pain Medicine at Boston Children’s Hospital.
Huggable, a creation of the MIT Media Lab’s Personal Robots Group and the Boston Children’s Simulator Program, comes into Beatrice’s room to chat, play games like “I Spy” and tell jokes. The session is recorded on video, and a bracelet called a Q Sensor collects Beatrice’s physiologic data–changes in skin conductance, temperature and motion that may indicate distress. Researchers at Northeastern University are analyzing these data to gauge the robot’s effect. Eventually, Huggable will be able to react to the data and respond accordingly—offering relaxation exercises and guided imagery, for example, if a child remains anxious.
Currently, Huggable is voiced by Child Life staff, but the ultimate goal is for it to work autonomously. Beatrice is part of a 90-child study comparing Huggable, an ordinary teddy bear and a tablet Huggable image.
I admit: My immediate thought on seeing Huggable was that kids would immediately see him (her?) as a fake, but the bear’s robotic nature doesn’t seem to faze them. As Logan says in the video:
I think there’s a way of connecting with kids that’s different than what grownups have to offer. They have incredible imaginations. And they can really suspend disbelief. There can be a true relationship that develops between Huggable and a patient.
Jason Kahn, PhD, is a co-founder of Neuro’motion, a research associate at Boston Children’s Hospital, and a part-time instructor at Harvard Medical School.
Earlier this month, I traveled to SXSW Interactive 2015 to introduce my company, Neuro’motion. We build mobile video games and toys to build emotional strength in children, improve access to mental health care and provide a drug-free alternative for behavioral health. We were born from research at Boston Children’s Hospital and our mission is to get our games into as many people’s hands as possible. …
Much has been written about the successes that result from medical hackathons, in which people from across the health care ecosystem converge to solve challenges. For example, PillPack, which formed out of MIT Hacking Medicine, recently closed an $8.75 million funding round. But is this a realistic snapshot of what happens after a hackathon? We took a look at two of the 16 teams that competed at Boston Children’s Hospital’s Hacking Pediatrics last year. …

Children and adolescents constitute almost a third of the world’s population—2.2 billion individuals—and almost 90 percent live in low-income and middle-income countries, where they form up to half of the population. Yet, for many years, child mental health has largely been glossed over—with long-term negative effects on educational attainment in addition to chronic disability and lost productivity.
Major international non-governmental organizations and United Nations agencies work in settings where children are at risk for mental health difficulties. However, with the exception of the World Health Organization (WHO), these agencies often fail to acknowledge or focus on child mental health issues. In 2005, the WHO Atlas of Child and Adolescent Mental Health Resources reported that less than one third of 66 countries surveyed had an entity with sole responsibility for child mental health programming, and that national budgets rarely had identifiable funding for child mental health services. …
When teenagers come to an emergency department expressing suicidal thoughts or after a suicide attempt, the accepted model of care is to evaluate, then either send them home or keep them in the ED until an inpatient psychiatric bed becomes available.
The wait for an inpatient bed can take hours, even days. No psychiatric treatment is given. The child is simply “boarded” – kept waiting in the ED under supervision, a practice that can increase distress for the child and family, while taking ED beds out of circulation for other acutely ill patients.
“Generally speaking, there is no history of providing psychiatric treatment in the emergency room setting,” says Elizabeth Wharff, director of the Emergency Psychiatry Service at Children’s Hospital Boston. “Since the late 1990s, we have seen a significant increase in the number of cases where an adolescent comes to our emergency room with suicidality and needs inpatient care, but there are no available psychiatric beds anywhere in the area.” …
Bill Bosl is used to looking for patterns. A computer scientist trained in atmospheric physics, geophysics and mathematics, he’s invented a method for computing properties of porous materials from CT scans. At the Lawrence Livermore National Lab, he worked on remote sensing problems, reading complex wave patterns to discern the location of groundwater, oil deposits and fault lines.
Today, he’s trying to measure thought – to compute what’s going on in hard-to-understand disorders like autism, which is currently diagnosed purely on the basis of behavior. “The mathematical methods are very similar,” he says. “You’re analyzing waves.”
The waves in this case are electroencephalograms (EEGs), those squiggly lines generated by electrical activity in the brain. In autism, …
I’m playing Space Invaders on a laptop in front of a group of psychiatrists and social workers, and frankly feeling pretty nervous. My finger is attached to a pulse oximeter, which measures my heart rate. As I struggle with the arrow keys to hit the incoming targets, I notice I’m shooting blanks. I take a deep breath to try to calm down. My heart rate drops, and once again I’m firing real missiles, scoring hits.
This same game, adapted from the old 1978 Space Invaders, is being tested in young psychiatry patients here …
