By Jessica Hamzelou JACK NICHOLSON has a lot to answer for. One of the knock-on effects of hit 1975 movie One Flew Over the Cuckoo’s Nest was a public backlash against electroconvulsive therapy (ECT). The treatment, used since the 1930s for a wide range of mental health conditions, delivers a jolt of electricity to the brain big enough to trigger a seizure. The film’s brutal depiction of ECT and lobbying helped it fall out of favour in the 1980s and 1990s. But ECT may now be undergoing a revival, led by psychiatrists who champion it because of its success rate. “It’s the most effective treatment we have in psychiatry,” says George Kirov at Cardiff University, UK, who oversees ECT treatments in the area. A report from the UK Royal College of Psychiatrists last September showed that three-quarters of people with mental health problems felt improvement after having ECT. And psychiatrists say that a similar percentage of people who have schizophrenia that doesn’t respond to drug treatment find ECT effective. “I’ve never seen an ECT treatment that doesn’t work,” says Helen Farrell, a psychiatrist at the Beth Israel Deaconess Medical Center in Boston. “People have such a skewed view of electroconvulsive therapy. It is seen as primitive and horrific“ Mounting evidence has convinced the US Food and Drug Administration (FDA) to consider reclassifying ECT devices to make the technology more accessible for people with depression or bipolar disorder. The public will still take some convincing, however. In a 2005 survey in Switzerland, for example, 56 per cent were against ECT, while just 1 per cent said they were in favour. © Copyright Reed Business Information Ltd.

By MIKE SACKS You’ve seen me. I know you have. I’m the guy wearing gloves on the subway in October. Or even into April. Perhaps I’m wearing just one glove, allowing my naked hand to turn the pages of a book. No big deal. Just another one-gloved commuter, heading home. If it’s crowded, you may have noticed me doing my best to “surf,” sans contact, until the car comes to a stop, in which case I may knock into a fellow passenger. Aboveground you may have seen me acting the gentleman, opening doors for others with a special paper towel I carry in my front left pocket for just such a momentous occasion. No? How about that guy walking quickly ahead of you, the one impishly avoiding sidewalk cracks? Or perhaps you’ve noticed a stranger who turns and makes eye contact with you for seemingly no reason. You may have asked, “You got a problem?” Oh, I definitely have a problem. But it has nothing to do with you, sir or madam. (And, yes, even in my thoughts I refer to you as “sir” and “madam.”) The problem here is what multiple doctors have diagnosed as obsessive-compulsive disorder. You may refer to it by its kicky abbreviation, O.C.D. I prefer to call it Da Beast. Da Beast is a creature I have lived with since I was 11, a typical age for O.C.D. to snarl into one’s life without invitation or warning. According to the International O.C.D. Foundation, roughly one in 100 adults suffers from the disorder. Each of us has his or her own obsessive thoughts and fears to contend with. My particular beast of burden is a fear of germs and sickness. It’s a popular one, perhaps the most common. © 2016 The New York Times Company

Laura Sanders A busy protein known for its role in aging may also have a hand in depression, a study on mice hints. Under certain circumstances, the aging-related SIRT1 protein seems to make mice despondent, scientists report August 10 in the Journal of Neuroscience. The results are preliminary, but they might ultimately help find new depression treatments. Today’s treatments aren’t always effective, and new approaches are sorely needed. “This is one potential new avenue,” says study coauthor Deveroux Ferguson of the University of Arizona College of Medicine in Phoenix. Ferguson and colleagues subjected mice to 10 days of stressful encounters with other mice. After their demoralizing ordeal, the mice showed signs of depression, such as eschewing sugar water and giving up attempts to swim. Along with these signs of rodent despair, the mice had more SIRT1 gene activity in the nucleus accumbens, a brain area that has been linked to motivation and depression. Resveratrol, a compound found in red grapes, supercharges the SIRT1 protein, making it more efficient at its job. When Ferguson and colleagues delivered resveratrol directly to the nucleus accumbens, mice displayed more signs of depression and anxiety. When the researchers used a different compound to hinder SIRT1 activity, the mice showed the opposite effect, appearing bolder in some tests than mice that didn’t receive the compound. |© Society for Science & the Public 2000 - 2016.

By Ann Griswold, Autism shares genetic roots with obsessive-compulsive disorder (OCD) andattention deficit hyperactivity disorder (ADHD). The three conditions have features in common, such as impulsivity. New findings suggest that they also share a brain signature. The first comparison of brain architecture across these conditions has found that all are associated with disruptions in the structure of the corpus callosum. The corpus callosum is a bundle of nerve fibers that links the brain’s left and right hemispheres. The results appeared July 1 in the American Journal of Psychiatry. Clinicians may find it difficult to distinguish autism from ADHD based on symptoms alone. But if the conditions are marked by similar structural problems in the brain, the same interventions might be useful no matter what the diagnosis is, says lead researcher Stephanie Ameis, assistant professor of psychiatry at the University of Toronto. The unique aspects of each condition might arise from other brain attributes, such as differences in the connections between neurons, says Thomas Frazier, director of research at the Cleveland Clinic Foundation. “A reasonable conclusion is that autism and ADHD don’t differ dramatically in a structural way, but could differ in connectivity,” says Frazier, who was not involved in the study. Ameis’ team examined the brains of 71 children with autism, 31 with ADHD, 36 with OCD and 62 typical children using diffusion tensor imaging. This method provides a picture of the brain’s white matter, the long fibers that connect nerve cells, by measuring the diffusion of water across these fibers. © 2016 Scientific American

By BENEDICT CAREY HOLYOKE, Mass. — Some of the voices inside Caroline White’s head have been a lifelong comfort, as protective as a favorite aunt. It was the others — “you’re nothing, they’re out to get you, to kill you” — that led her down a rabbit hole of failed treatments and over a decade of hospitalizations, therapy and medications, all aimed at silencing those internal threats. At a support group here for so-called voice-hearers, however, she tried something radically different. She allowed other members of the group to address the voice, directly: What is it you want? “After I thought about it, I realized that the voice valued my safety, wanted me to be respected and better supported by others,” said Ms. White, 34, who, since that session in late 2014, has become a leader in a growing alliance of such groups, called the Hearing Voices Network, or HVN. At a time when Congress is debating measures to extend the reach of mainstream psychiatry — particularly to the severely psychotic, who often end up in prison or homeless — an alternative kind of mental health care is taking root that is very much anti-mainstream. It is largely nonmedical, focused on holistic recovery rather than symptom treatment, and increasingly accessible through an assortment of in-home services, residential centers and groups like the voices network Ms. White turned to, in which members help one another understand each voice, as a metaphor, rather than try to extinguish it. For the first time in this country, experts say, psychiatry’s critics are mounting a sustained, broadly based effort to provide people with practical options, rather than solely alleging abuses like overmedication and involuntary restraint. “The reason these programs are proliferating now is society’s shameful neglect of the severely ill, which creates a vacuum of great need,” said Dr. Allen Frances, a professor emeritus of psychiatry at Duke University. © 2016 The New York Times Company

Nicola Davis Scientists have discovered 17 separate genetic variations that increase the risk of a person developing depression. The findings, which came from analysing DNA data collected from more than 300,000 people, are the first genetics links to the disease found in people of European ancestry. The scientists say the research will contribute to a better understanding of the disease and could eventually lead to new treatments. They also hope it will reduce the stigma that can accompany depression. According to Nice, up to 10% of people seen by practitioners in primary care have clinical depression, with symptoms including a continuously low mood, low self-esteem, difficulties making decisions and lack of energy. Both environmental and genetic factors are thought to be behind depression, with the interaction between the two also thought to be important. But with a large number of genetic variants each thought to make a tiny contribution to the risk of developing the condition, unravelling their identity has proved challenging. While previous studies have turned up a couple of regions in the genome of Chinese women that might increase the risk of depression, the variants didn’t appear to play a role in depression for people of European ancestry. © 2016 Guardian News and Media Limited

By David Levine Almost seven percent of U.S. adults—about 15.7 million people—are diagnosed with major depression disorder, according to the National Institute of Mental Health (NIMH). The Centers for Disease Control and Prevention report that depression causes 200 million lost workdays each year at a cost to employers of between $17 billion and $44 billion. The statistics for anxiety disorders are not great either. The most common mental illnesses in the U.S., they affect 40 million adults age 18 and older, costing the economy more than $42 billion a year. In my twenties, I developed panic disorder. I failed to get better on most medications and therapy. As I reported in an article earlier this year, it took me years to find a medication that worked. Because it took me so long to be diagnosed and treated properly, I have always been interested in alternative treatments for depression and anxiety. Two years ago I attended two sessions at the World Science Festival on the use of electrical therapy to treat depression and anxiety. The first event was Spark of Genius? Awakening a Better Brain, a panel discussion moderated by ABC News Chief Health & Medical Editor Richard Besser. The panel discussed what is known about treating the brain and the ethical and legal complications of brain enhancement. (You can watch it online at the World Science Festival website.) The second panel, "Electric Medicine and the Brain" was moderated by John Rennie, former editor in chief of Scientific American His panel focused on the use of "electroceuticals," a term coined by researchers at GlaxoSmithKline to refer to all implantable devices being used to treat mental illnesses and being explored in the treatment of metabolic, cardiovascular and inflammatory disorders. © 2016 Scientific American

By DENISE GRADY Could pernicious anemia, a disease caused by a vitamin B12 deficiency, have explained the many strange behaviors of Mary Todd Lincoln? She was not exactly a model first lady. Historians have had a field day describing her violent temper, wild shopping sprees (she owned 300 pairs of kid gloves), depressed moods and all-consuming fears of burglars, storms and poverty. Late in life, at her son’s urging, she was committed to a mental hospital for several months. Plenty of theories, none proven, have been floated. She was bipolar. She had syphilis or that well known cause of feminine madness, menstrual trouble. She was spoiled and narcissistic. She never recovered from a road accident in which her head hit a rock. She lost her mind grieving the deaths of three of her four sons and her husband’s assassination. The latest addition to the list of possible diagnoses comes from Dr. John G. Sotos, a cardiologist, technology executive at Intel and one of the medical consultants who helped dream up the mystery diseases that afflicted patients on the television show “House.” Dr. Sotos has long been interested in difficult diagnoses, and has written a self-published book suggesting that Abraham Lincoln had a genetic syndrome that caused cancers of the thyroid and adrenal glands. In an interview, Dr. Sotos said that while he was studying President Lincoln, he came across something that intrigued him about Mrs. Lincoln: an 1852 letter mentioning that she had a sore mouth. He knew that vitamin B deficiencies could cause a sore tongue, and he began looking into her health. © 2016 The New York Times Company

By Nicholas Bakalar A new study has identified a bacterial blueprint for chronic fatigue syndrome, offering further evidence that it is a physical disease with biological causes and not a psychological condition. Chronic fatigue syndrome is a condition that causes extreme and lasting fatigue, preventing people from taking part in even the most routine daily activities. There are no tests to confirm the diagnosis, which has prompted speculation that it is a psychological condition rather than a physical illness. In a study published in Microbiome, researchers recruited 48 people with C.F.S. and 39 healthy controls. Then they analyzed the quantity and variety of bacteria species in their stool. They also searched for markers of inflammation in their blood. The stool samples of those with C.F.S. had significantly lower diversity of species compared with the healthy people — a finding typical of inflammatory bowel disease as well. The scientists also discovered that people with C.F.S. had higher blood levels of lipopolysaccharides, inflammatory molecules that may indicate that bacteria have moved from the gut into the bloodstream, where they can produce various symptoms of disease. Using these criteria, the researchers were able to accurately identify more than 83 percent of C.F.S. cases based on the diversity of their gut bacteria and lipopolysaccharides in their blood. Finding a biomarker for C.F.S. has been an ongoing goal for researchers who hope to one day develop a diagnostic test for the condition. Still, the senior author of the study, Maureen R. Hanson, a professor of molecular biology at Cornell, said the bacteria blueprint in the new study is not yet a method of definitively diagnosing C.F.S. The importance of the finding, she said, is that it may offer new clues as to why people have these symptoms. © 2016 The New York Times Company

By ERICA GOODE Irving Gottesman, a pioneer in the field of behavioral genetics whose work on the role of heredity in schizophrenia helped transform the way people thought about the origins of serious mental illness, died on June 29 at his home in Edina, Minn., a suburb of Minneapolis. He was 85. His wife, Carol, said he died while taking an afternoon nap. Although Dr. Gottesman had some health problems, she said, his death was unexpected, and several of his colleagues said they received emails from him earlier that day. Dr. Gottesman was perhaps best known for a study of schizophrenia in British twins he conducted with another researcher, James Shields, at the Maudsley Hospital in London in the 1960s. The study, which found that identical twins were more likely than fraternal twins to share a diagnosis of schizophrenia, provided strong evidence for a genetic component to the illness and challenged the notion that it was caused by bad mothering, the prevailing view at the time. But the findings also underscored the contribution of a patient’s environment: If genes alone were responsible for schizophrenia, the disorder should afflict both members of every identical pair; instead, it appeared in both twins in only about half of the identical pairs in the study. This interaction between nature and nurture, Dr. Gottesman believed, was critical to understanding human behavior, and he warned against tilting too far in one direction or the other in explaining mental illness or in accounting for differences in personality or I.Q. © 2016 The New York Times Company

Anthony Devlin/ Antidepressant use is at an all-time in high in England, where prescriptions filled for these drugs has doubled over the last decade. Figures from the Health and Social Care Information Centre show that in 2015, 61 million prescriptions were filled for antidepressant drugs, including citalopram and fluoxetine. This is up from 57.1 million in 2014, and 29.4 million back in 2005. “The reasons for this increase in antidepressant prescriptions could include a greater awareness of mental illness and more willingness to seek help,” says Gillian Connor of the charity Rethink Mental Illness. “However, with our overstretched and underfunded mental health services, too often antidepressants are the only treatment available.” UK guidelines suggest that people should be offered antidepressants as a first treatment option for moderate depression, but some critics argue that it would be better to steer people to talking therapies. In May, Andrew Green, a GP in East Riding and chairman of the British Medical Association’s Clinical and Prescribing Subcommittee, told a meeting of the UK’s All-Party Parliamentary Group for Prescribed Drug Dependence that one of the reasons doctors resort to prescribing antidepressants is because the waiting lists for talking therapies are so long. © Copyright Reed Business Information Ltd.

Jackie Goldstein Mental illness has been part of human society throughout recorded history, but how we care for people with mental disorders has changed radically, and not always for the better. In Colonial days, settlers lived in sparsely populated rural communities where sanctuary and community support enabled the tradition of family care brought from England. "Distracted persons" were acknowledged, but erratic behavior wasn't associated with disease. Records indicate unusual tolerance of bizarre behavior. When 18th century Pastor Joseph Moody of York, Maine, unable to face crowds, delivered sermons with a handkerchief covering his face, his behavior was tolerated for three years before he was relieved of his duties. As urban areas grew in size and number, a transient poor population with no access to family support led to almshouses, the first form of institutionalization, inspired by 18th century reforms in Europe. A Philadelphia Quaker who had visited an English retreat brought the idea to this country and in 1817 founded the Friends Asylum, a self-sufficient farm that offered a stress-free environment known as "moral treatment." Other private asylums followed, but they soon became overcrowded. By the late 19th century, this was addressed with larger state hospitals, which soon became overcrowded as well. People with mental disorders are more likely to be stigmatized owing to fear and misunderstanding when they aren't part of the community. And stigmatization can discourage those with a mental disorder from seeking or complying with treatment. © 2016 npr

By Tara Parker-Pope About one in eight women take an antidepressant at some time during pregnancy, reports Roni Rabin in today’s Science Times. But is it safe? Some new research shows that antidepressant use during pregnancy may be linked to certain problems in newborns. A new review of the medical literature concludes that treatment decisions for depression during pregnancy must be made on a case-by-case basis. “There’s not a one-size-fits-all answer,” said Dr. Kimberly Yonkers, a professor of psychiatry and obstetrics and gynecology at Yale School of Medicine who was the report’s lead author, and who acknowledged receiving research support from antidepressant manufacturers. “You can’t say, ‘Stop medication for all women because it’s harmful,’ and you can’t put all women on medication either.” To learn more, read the full story, “Depression Is a Dilemma for Women in Pregnancy,” and then please join the discussion below.

Angus Chen At the center of Geel, a charming Belgian town less than an hour's drive from of Antwerp, is a church dedicated to Dymphna, a saint believed to have the power to cure mental disorders. It's a medieval church with stone arches, spires and a half-built bell tower, and it has inspired an unusual centuries-old practice: For over 700 years, residents of Geel have been accepting people with mental disorders, often very severe mental disorders, into their homes and caring for them. It isn't meant to be a treatment or therapy. The people are not called patients, but guests or boarders. They go to Geel and join households to share a life with people who can watch over them. Today, there are about 250 boarders in Geel. One of them is a Flemish man named Luc Ennekans. He's slim and has green eyes, and he's 51 years old. NPR's Lulu Miller went to Geel and met him and his host family there and reported this story for Invisibilia. Like all of the guests in the town today, Ennekans first went to a public psychiatric hospital in Geel that manages the boarder program. Ennekans saw medical professionals and received treatment and an evaluation. Then he was paired with a household. His hosts, Toni Smit and Arthur Shouten, say that living with Ennekans was rough at the start. Ennekans became deeply attached to Smit. "If it were up to Luc, he would be hugging and kissing me all day," Smit says. He showered her with such affection, bringing her flowers, little kisses, linking arms with her on walks, that it began to interfere with Smit and Shouten's marriage. "You couldn't even give each other a hug or Luc is standing behind us," Shouten says. Wrinkles like this are common, according to the couple. They've had six boarders over the years, each with a unique set of challenges. © 2016 npr

By BENEDICT CAREY New York University’s medical school has quietly shut down eight studies at its prominent psychiatric research center and parted ways with a top researcher after discovering a series of violations in a study of an experimental, mind-altering drug. A subsequent federal investigation found lax oversight of study participants, most of whom had serious mental issues. The Food and Drug Administration investigators also found that records had been falsified and researchers had failed to keep accurate case histories. In one of the shuttered studies, people with a diagnosis of post-traumatic stress caused by childhood abuse took a relatively untested drug intended to mimic the effects of marijuana, to see if it relieved symptoms. “I think their intent was good, and they were considerate to me,” said one of those subjects, Diane Ruffcorn, 40, of Seattle, who said she was sexually abused as a child. “But what concerned me, I was given this drug, and all these tests, and then it was goodbye, I was on my own. There was no follow-up.” It’s a critical time for two important but still controversial areas of psychiatry: the search for a blood test or other biological sign of post-traumatic stress disorder, which has so far come up empty, and the use of recreational drugs like ecstasy and marijuana to treat it. At least one trial of marijuana, and one using ecstasy, are in the works for traumatized veterans, and some psychiatrists and many patients see this work as having enormous promise to reshape and improve treatment for trauma. But obtaining approval to use the drugs in experiments is still politically sensitive. Doctors who have done studies with these drugs say that their uncertain effects on traumatic memory make close supervision during treatment essential. © 2016 The New York Times Company

by German Lopez and Javier Zarracina After years of struggling with treatments for his worsening cancer, Roy was miserable — anxious, depressed, hopeless. Traditional cancer treatments had left him debilitated, and it was unclear whether they would save his life. But then Roy secured a spot in a clinical trial to test an exotic drug. The drug was not meant to cure his cancer; it was meant to cure his terror. And it worked. A few hours after taking a little pill, Roy declared to researchers, "Cancer is not important, the important stuff is love." His concerns about his imminent death had suddenly vanished — and the effects lasted for at least months, according to researchers. It was not a traditional antidepressant, like Zoloft, or anti-anxiety medication, like Xanax, that led Roy to reevaluate his life. It was a drug that has been illegal for decades but is now at the center of a renaissance in research: psilocybin, from hallucinogenic magic mushrooms. Psychologists and psychiatrists have been studying hallucinogens for decades — as treatment for things like alcoholism and depression, and to stimulate creativity. But support for studies dried up in the 1970s, after the federal government listed many psychedelics as Schedule 1 drugs. But now researchers are giving the drugs another look. © 2016 Vox Media, Inc.

By Sara Chodosh Although scientists have learned a lot about the brain in the last few decades, approaches to treating mental illnesses have not kept up. As neuroscientists learn more about brain circuits, Stanford psychiatrist Amit Etkin foresees a time when diagnoses will be based on brain scans rather than symptoms. Etkin, who will be speaking at the World Economic Forum’s Annual Meeting of the New Champions in Tianjin, China, from June 26 to 28, spoke with Scientific American about his research on the neurological basis of emotional disorders and the future of mental health treatment. The high cost of treating mental illness doesn’t get talked about very much. Why is that? It’s a really interesting issue. The costs associated with mental illness are not just the care of people who have an illness, which often starts early in life and continues as a lifelong process, but also the cost to employers in decreased productivity and the cost to society in general. A report that came out recently in Health Affairs showed that spending within our health system in the U.S. is greater for mental illness than for any other area of medicine, and yet our understanding of these illnesses is incredibly backwards. Treatments are no different than they were 40 years ago, so that feels like a problem that is only getting bigger without an obvious solution. Why hasn’t there been much progress? It was really not until about 10 years ago that [mental health professionals] started realizing how little difference we have made. There are a few fundamental issues and mistakes we’ve made. One is that in the absence of knowing what the causes of the illnesses that we treat are, we focus on the symptoms, and that has already led us down the wrong path. If you go to another country and you ask somebody to tell you their symptoms, as a clinician you might have the sense that they have anxiety or depression. In Asian countries they express that in a somatic way: “I can’t sleep” or “I feel weak.” The biology cannot be that different, but the symptoms are different because they’re culturally bound. If you look at different parts of the U.S. you’ll see people expressing symptoms in different ways depending on their local culture. If that’s the case, then a symptom-based definition is problematic. The long and short of it is that people have named syndromes or disorders that they don’t actually know represent a valid entity that is distinct from another entity. © 2016 Scientific American

Lisa Fine Jess Thom says the word "biscuit" about 16,000 times every day. Her brother-in-law counted once. That's just one of the tics that Thom, a London-based performance artist, has to manage as part of her life with Tourette's syndrome, a neurological disorder characterized by involuntary vocal or motor tics. Specialists say the condition affects as many as 300,000 children in the United States, though many are undiagnosed. Thom has had tics since childhood, but she wasn't diagnosed until her 20s. "What disables me ... is other people's misunderstanding," she says. "What's exciting is that it's something we all have power to change." The condition is far more common than many people realize, and many misperceptions about it still exist, says Kevin McNaught, executive vice president of the advocacy group Tourette Association of America. "It's not a rare disorder," McNaught says, citing an estimated 1 in 100 school-age children with the condition, including many who aren't diagnosed until adulthood, if at all. Michael Chichioco, a California high school senior who has Tourette's syndrome, says he used to be bullied at school, with kids trying to trigger him to have outbursts. His tics come out more prominently when he is nervous or excited. © 2016 npr

Angus Chen Rachel Star Withers runs a YouTube channel where she performs goofy stunts on camera and talks about her schizophrenia. Since 2008, when the then 22-year-old revealed her diagnosis online, tens of thousands of people have seen her videos. Some of them have a psychotic disorder or mood disorders themselves, or know people who do. They say her explanation about what a symptom like hallucinations feels like can be really helpful. So can Rachel's advice on ways to cope with them, like getting a dog or a cat. If the animal doesn't react to the hallucination, then it's probably not real, she says. We talked with people about how Withers' videos have helped them understand these diseases. What follows is a Q&A with two of these people. The interviews have been edited for length and clarity. Julia Billingsley is 22 years old and from Peoria, Ill. She learned she has schizophrenia last year, but she says her earliest encounter with the disease was back when she was very young. Her mother has schizophrenia, too, Billingsley says, and often had a delusion that their home was bugged. Julia, you started developing symptoms last year. Do you remember the first thing that happened to you? I'd just started dating my current boyfriend. And I'd be over at his house and I'd go to the bathroom. And this thought, this intrusive thought that wasn't my own at all would pop into my head like with force. And it would be like, hey. This room is bugged. And I was like, what? It made me stop.

By ROBERT F. WORTH In early 2012, a neuropathologist named Daniel Perl was examining a slide of human brain tissue when he saw something odd and unfamiliar in the wormlike squiggles and folds. It looked like brown dust; a distinctive pattern of tiny scars. Perl was intrigued. At 69, he had examined 20,000 brains over a four-decade career, focusing mostly on Alzheimer’s and other degenerative disorders. He had peered through his microscope at countless malformed proteins and twisted axons. He knew as much about the biology of brain disease as just about anyone on earth. But he had never seen anything like this. The brain under Perl’s microscope belonged to an American soldier who had been five feet away when a suicide bomber detonated his belt of explosives in 2009. The soldier survived the blast, thanks to his body armor, but died two years later of an apparent drug overdose after suffering symptoms that have become the hallmark of the recent wars in Iraq and Afghanistan: memory loss, cognitive problems, inability to sleep and profound, often suicidal depression. Nearly 350,000 service members have been given a diagnosis of traumatic brain injury over the past 15 years, many of them from blast exposure. The real number is likely to be much higher, because so many who have enlisted are too proud to report a wound that remains invisible. For years, many scientists have assumed that explosive blasts affect the brain in much the same way as concussions from football or car accidents. Perl himself was a leading researcher on chronic traumatic encephalopathy, or C.T.E., which has caused dementia in N.F.L. players. Several veterans who died after suffering blast wounds have in fact developed C.T.E. But those veterans had other, nonblast injuries too. No one had done a systematic post-mortem study of blast-injured troops. That was exactly what the Pentagon asked Perl to do in 2010, offering him access to the brains they had gathered for research. It was a rare opportunity, and Perl left his post as director of neuropathology at the medical school at Mount Sinai to come to Washington. © 2016 The New York Times Company
