Schizophrenia and related mental illnesses can have a devastating effect on people who suffer from them, often making it impossible for them to work or maintain normal social relationships. Antipsychotic drugs are usually the first line of defense, but they can have serious side effects. A new study concludes that psychological approaches could be an alternative for patients who either can’t or won’t take medication, although some critics continue to question the effectiveness of these interventions. Schizophrenia, which can involve hallucinations, delusions, paranoia, emotional problems, and severe difficulty focusing on daily tasks, affects about 1% of populations worldwide. More than 20 antipsychotic medications, such as risperidone, haloperidol, and clozapine, are now on the market, and they are often effective in temporarily relieving the worse symptoms. But when taken for extended periods, such drugs can cause uncontrollable muscle movements, serious weight gain, and higher risk of heart attacks. In recent years, a number of psychiatrists and psychologists have begun to advocate psychological approaches, including an approach called cognitive behavioral therapy (CBT), as an adjunct to antipsychotic drugs. With CBT, which has long been shown to be effective for depression and anxiety disorders, a therapist takes the subject through a series of guided steps designed to explore alternative interpretations and explanations of what he or she is experiencing, with the goal of changing both outlook and behavior. A schizophrenic patient who is having hallucinations might be encouraged to stop trying to fight them off or suppress them, for example, or to stop engaging with voices in his or her head, to test how strong such symptoms really are and how much control they exert over the subject’s life. The technique also involves what practitioners call “normalization”: The patient might be reassured that hearing voices and seeing things that are not there is an experience that many normal people have from time to time, thus reducing some of the anxiety that makes sufferers feel distressed and isolated. © 2014 American Association for the Advancement of Science

By James Gallagher Health and science reporter, BBC News Changing the way people think about and deal with schizophrenia could be as effective as drugs, say researchers. Cognitive behavioural therapy is an officially recommended treatment, but is available to less than 10% of patients in the UK with schizophrenia. A study published in the Lancet indicates CBT could help the many who refuse antipsychotic medication. Experts say larger trials are needed. About four-in-10 patients benefit from taking antipsychotic medication. But the drugs do not work for the majority and they cause side-effects such as type 2 diabetes and weight gain. Up to half of patients with schizophrenia end up not taking the drugs. The study looked at cognitive behaviour therapy in 74 people. The therapy works by identifying an individual patient's problem - such as hearing voices, paranoid thinking or no longer going out of the house - and developing techniques to deal with them. Prof Tony Morrison, director of the psychosis research unit at Greater Manchester West Mental Health Foundation Trust, said: "We found cognitive behavioural therapy did reduce symptoms and it also improved personal and social function and we demonstrated very comprehensively it is a safe and effective therapy." It worked in 46% of patients, approximately the same as for antipsychotics - although a head-to-head study directly comparing the two therapies has not been made. Douglas Turkington, professor of psychiatry at Newcastle University, said: "One of our most interesting findings was that when given the option, most patients were agreeable to trying cognitive therapy."

By BENEDICT CAREY BETHESDA, Md. — The police arrived at the house just after breakfast, dressed in full riot gear, and set up a perimeter at the front and back. Not long after, animal rights marchers began filling the street: scores of people, young and old, yelling accusations of murder and abuse, invoking Hitler, as neighbors stepped out onto their porches and stared. It was 1997, in Decatur, Ga. The demonstrators had clashed with the police that week, at the Yerkes National Primate Research Center at nearby Emory University, but this time, they were paying a personal call — on the house of the center’s director, inside with his wife and two teenage children. “I think it affected the three of them more than it did me, honestly,” said Dr. Thomas R. Insel, shaking his head at the memory. “But the university insisted on moving all of us to a safe place for a few days, to an ‘undisclosed location.’ “I’ll say this. I learned that if you’re going to take a stand, you’re going to make some people really angry — so you’d better believe in what you’re doing, and believe it completely.” For the past 11 years, Dr. Insel, a 62-year-old brain scientist, has run an equally contentious but far more influential outfit: the National Institute of Mental Health, the world’s leading backer of behavioral health research. The job comes with risk as well as power. Patient groups and scientists continually question the agency’s priorities, and politicians occasionally snipe at its decisions. Two previous directors resigned in the wake of inflammatory statements (one on marijuana laws, one comparing urban neighborhoods to jungles), and another stepped down after repeatedly objecting to White House decisions. © 2014 The New York Times Company

By RICHARD A. FRIEDMAN, M.D. “How the Federal Government Destroyed the Mental Illness Treatment System”: That subtitle is the opening shot across the bow in this jeremiad of a book by the psychiatrist Dr. E. Fuller Torrey. It could just as well have read: “How a group of well-intentioned, starry-eyed idealists made a hash of mental health care.” You could hardly blame them for trying, though. The care of people with serious mental illness was long a national disgrace. By the 1950s, slightly more than half a million psychiatric patients resided in overcrowded and underfunded state mental hospitals, often under appalling conditions. Related Coverage Enter a group of high-minded psychiatrists with a vision to “create a brave new world, a mentally healthy America,” in Dr. Torrey’s words. Armed with little more than optimism, they helped start the National Institute of Mental Health and set in motion an ambitious agenda for the next half-century: closing the state mental hospitals, initiating a federal takeover of the mental health system, and creating a nationwide network of community mental health centers. Reform was well underway when President John F. Kennedy endorsed this new era in mental health in a 1963 speech, calling for a “bold new approach” in which “reliance on the cold mercy of custodial isolation will be supplanted by the open warmth of community concern and capability.” Those were heady days in American psychiatry, when psychoanalysis and the mental hygiene movement held sway and promised to cure all manner of ills by early intervention and improving the social environment. In hindsight, the therapeutic zeal of these professionals was impressively naïve: They were certain that severely mentally ill patients in state hospitals — many living there for decades — would magically adjust to the community and do well with outpatient treatment. How wrong they proved to be. © 2014 The New York Times Company

By Tia Ghose and LiveScience Neurons derived from schizophrenic patients. Image: Dr. Kristen Brennand, Salk Institute for Biological Studies. Some so-called jumping genes that copy and paste themselves throughout the genome may be linked to schizophrenia, new research suggests. The new study, published Jan. 2 in Neuron, suggests these jumping genes may alter how neurons (or nerve cells in the brain) form during development, thereby increasing the risk of schizophrenia, study co-author Dr. Tadafumi Kato, a neurobiologist at the RIKEN Brain Science Institute in Japan, wrote in an email. Jumping genes, or retrotransposons, are mobile genetic elements that copy and paste themselves at different places throughout the genome. About half of the human genome is made of these mysterious elements, compared with the 1 percent of genes that actually code for making proteins, Kato said. Earlier studies had found that a certain type of jumping gene, known as long interspersed nuclear element-1 (LINE-1), was active in human brain cells. Kato and his colleagues wondered whether they might play a role in mental illness. To find out, the team conducted a post-mortem analysis of 120 human brains, 13 from patients who had been diagnosed with schizophrenia. The team found a higher number of LINE-1 copies in the brains of schizophrenics compared with other groups. © 2014 Scientific American

People with severe mental illness such as schizophrenia or bipolar disorder have a higher risk for substance use, especially cigarette smoking, and protective factors usually associated with lower rates of substance use do not exist in severe mental illness, according to a new study funded by the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health. Estimates based on past studies suggest that people diagnosed with mood or anxiety disorders are about twice as likely as the general population to also suffer from a substance use disorder. Statistics from the 2012 National Survey on Drug Use and Health indicate close to 8.4 million External Web Site Policy adults in the United States have both a mental and substance use disorder. However, only 7.9 percent of people receive treatment for both conditions, and 53.7 percent receive no treatment at all, the statistics External Web Site Policy indicate. “Drug use impacts many of the same brain circuits that are disrupted in severe mental disorders such as schizophrenia,” said NIDA Director Dr. Nora D. Volkow. “While we cannot always prove a connection or causality, we do know that certain mental disorders are risk factors for subsequent substance use disorders, and vice versa.” In the current study, 9,142 people diagnosed with schizophrenia, schizoaffective disorder, or bipolar disorder with psychotic features, and 10,195 controls matched to participants according to geographic region, were selected using the Genomic Psychiatry Cohort program. Mental disorder diagnoses were confirmed using the Diagnostic Interview for Psychosis and Affective Disorder (DI-PAD), and controls were screened to verify the absence of schizophrenia or bipolar disorder in themselves or close family members. The DI-PAD was also used for all participants to determine substance use rates.

By MICHAEL M. PHILLIPS Roman Tritz’s memories of the past six decades are blurred by age and delusion. But one thing he remembers clearly is the fight he put up the day the orderlies came for him. “They got the notion they were going to come to give me a lobotomy,” says Mr. Tritz, a World War II bomber pilot. “To hell with them.” The orderlies at the veterans hospital pinned Mr. Tritz to the floor, he recalls. He fought so hard that eventually they gave up. But the orderlies came for him again on Wednesday, July 1, 1953, a few weeks before his 30th birthday. This time, the doctors got their way. The U.S. government lobotomized roughly 2,000 mentally ill veterans—and likely hundreds more—during and after World War II, according to a cache of forgotten memos, letters and government reports unearthed by The Wall Street Journal. Besieged by psychologically damaged troops returning from the battlefields of North Africa, Europe and the Pacific, the Veterans Administration performed the brain-altering operation on former servicemen it diagnosed as depressives, psychotics and schizophrenics, and occasionally on people identified as homosexuals. The VA doctors considered themselves conservative in using lobotomy. Nevertheless, desperate for effective psychiatric treatments, they carried out the surgery at VA hospitals spanning the country, from Oregon to Massachusetts, Alabama to South Dakota. The VA’s practice, described in depth here for the first time, sometimes brought veterans relief from their inner demons. Often, however, the surgery left them little more than overgrown children, unable to care for themselves. Many suffered seizures, amnesia and loss of motor skills. Some died from the operation itself. Mr. Tritz, 90 years old, is one of the few still alive to describe the experience. “It isn’t so good up here,” he says, rubbing the two shallow divots on the sides of his forehead, bracketing wisps of white hair.

Imagine this: Every day, you can feel people looking at you warily. They want to hurt you. Even the police are out to get you. You try to rid your mind of all the ill-intentioned people, but you can't ignore the other thing that is gnawing at you. Those bugs on your arm won't leave you alone, no matter how often you gouge at them. Such are the hallucinations and paranoia felt by those with a stimulant drug addiction. Sometimes the substance abuse is so severe it causes neurological damage and psychosis becomes a chronic condition. Combine untreated addiction with homelessness and physical health problems, and you get a health emergency. Vancouver police and the region's health authorities are desperately trying to figure out how to help the most vulnerable of mentally ill drug addicts. The province estimates that roughly 130,000 people in British Columbia suffer from a severe addiction and/or mental health illness. But police and emergency workers are increasingly dealing with a much smaller group of people whose brains have been damaged by their stimulant addiction and who appear to be responsible for random violent acts on Vancouver's streets. Dr. Nader Sharifi, addiction medicine lead with the Fraser Health Authority, said there are few good treatment options for those people. "It's a bit of a challenging question, because what we have available isn't necessarily structured for this patient sub-type. It's either structured for addiction, or structured for mental health illness, but not necessarily the two together." © CBC 2013

By JULIE CRESWELL RALEIGH, N.C. — As darkness fell on a Friday evening over downtown Raleigh, N.C., Michael Lyons, a paramedic supervisor for Wake County Emergency Medical Services, slowly approached the tall, lanky man who was swaying back and forth in a gentle rhythm. In answer to Mr. Lyons’s questions, the man, wearing a red shirt that dwarfed his thin frame, said he was bipolar, schizophrenic and homeless. He was looking for help because he did not think his prescribed medication was working. In the past, paramedics would have taken the man to the closest hospital emergency room — most likely the nearby WakeMed Health and Hospitals, one of the largest centers in the region. But instead, under a pilot program, paramedics ushered him through the doors of Holly Hill Hospital, a commercial psychiatric facility. “He doesn’t have a medical complaint, he’s just a mental health patient living on the street who is looking for some help,” said Mr. Lyons, pulling his van back into traffic. “The good news is that he’s not going to an E.R. That’s saving the hospital money and getting the patient to the most appropriate place for him,” he added. The experiment in Raleigh is being closely watched by other cities desperate to find a way to help mentally ill patients without admitting them to emergency rooms, where the cost of treatment is high — and unnecessary. While there is evidence that other types of health care costs might be declining slightly, the cost of emergency room care for the mentally ill shows no sign of ebbing. Nationally, more than 6.4 million visits to emergency rooms in 2010, or about 5 percent of total visits, involved patients whose primary diagnosis was a mental health condition or substance abuse. That is up 28 percent from just four years earlier, according to the latest figures available from the Agency for Healthcare Research and Quality in Rockville, Md. By one federal estimate, spending by general hospitals to care for these patients is expected to nearly double to $38.5 billion in 2014, from $20.3 billion in 2003. © 2013 The New York Times Company

Amanda Mascarelli In children with certain gene variants, symptoms similar to common learning disabilities could be omens of serious psychiatric conditions. People who carry high-risk genetic variants for schizophrenia and autism have impairments reminiscent of disorders such as dyslexia, even when they do not yet have a mental illness, a new study has found. The findings offer a window into the brain changes that precede severe mental illness and hold promise for early intervention and even prevention, researchers say. Rare genetic alterations called copy number variants (CNVs), in which certain segments of the genome have an abnormal number of copies, play an important part in psychiatric disorders: Individuals who carry certain CNVs have a several-fold increased risk of developing schizophrenia or autism1. But previous studies were based on individuals who already have a psychiatric disorder, and until now, no one had looked at what effects these CNVs have in the general population. In a study published today in Nature2, researchers report that people with these variants but no diagnosis of autism or a mental illness still show subtle brain changes and impairments in cognitive function. “In psychiatry we always have the problem that disorders are defined by symptoms that patients experience or tell us about, or that we observe,” says study co-author Andreas Meyer-Lindenberg, a psychiatrist and the director the Central Institute of Mental Health in Mannheim, Germany, affiliated with the University of Heidelberg. This work, on the other hand, provides a glimpse into the biological underpinnings of people who are at risk of psychiatric disorders, he says. The team searched a genealogical database of more than 100,000 Icelanders, focusing on 26 genetic variants that have been shown to increase the risk of schizophrenia or autism. They found that 1,178 people in the database, or 1.16% of the sample, carried one or more of these CNVs. © 2013 Nature Publishing Group

By Sandra Steingard, What does it mean that the man who killed 12 people at the Washington Naval Yard had told people that he was “hearing voices”? I have spent 30 years as a psychiatrist treating people who are psychotic. Almost every day I meet with individuals who hear voices that no one else hears, are sure the TV or radio is talking to them or have such confused thinking that it is hard to understand what they are trying to tell me. Sometimes these patients lead quiet lives. But not uncommonly these voices get them into trouble. I’ve had patients who call the police repeatedly, demanding that they stop bugging their phone. And others who stay up all night talking back at the voices. Some accuse family members of being involved in the torment. In many cases, this is a frightening experience — for the people I see and those who love them. And the labels we use — “schizophrenia,” “bipolar disorder,” “psychosis” — only crudely capture these experiences. About 60 years ago, a group of drugs was discovered that appeared to quiet the voices, improve the clarity of thought and lessen the preoccupation with delusion beliefs. Originally called major tranquilizers and later renamed antipsychotic drugs, these have been considered essential for the treatment of people with schizophrenia. Once it was clear that these drugs were helpful in the short term, questions arose over how long people should remain on them. Studies done in the 1970s and 1980s looked at people who were stabilized after being treated with antipsychotic drugs for several months and then followed them for up to two years. Some continued on the drugs, while others stopped taking them. The relapse rate was much higher in the group that stopped the medications. Based on these studies, treatment guidelines now state that people should stay on anti-psychotics indefinitely. The problem with “indefinitely” is that antipsychotic drugs have many troubling side effects. © 1996-2013 The Washington Post

Daniel Freeman and Jason Freeman Which illness frightens you most? Cancer? Stroke? Dementia? To judge from tabloid coverage, the condition we should really fear isn't physical at all. "Scared of mum's schizophrenic attacks", "Knife-wielding schizophrenic woman in court", "Schizo stranger killed dad", "Rachel murder: schizo accused", and "My schizophrenic son says he'll kill… but he's escaped from secure hospitals 7 times" are just a few of dozens of similar headlines we found in a cursory internet search. Mental illness, these stories imply, is dangerous. And schizophrenia is the most dangerous of all. Such reporting is unhelpful, misleading and manipulative. But it may be even more inaccurate than it first appears. This is because scientists are increasingly doubtful whether schizophrenia – a term invented more than a century ago by the psychiatric pioneer Eugen Bleuler – is a distinct illness at all. This isn't to say that individuals diagnosed with the condition don't have genuine and serious mental health problems. But how well the label "schizophrenia" fits those problems is now a very real question. What's wrong with the concept of schizophrenia? For one thing, research indicates the term may simply be functioning as a catch-all for a variety of separate problems. Six main conditions are typically caught under the umbrella of schizophrenia: paranoia; grandiosity (delusional beliefs that one has special powers or is famous); hallucinations (hearing voices, for example); thought disorder (being unable to think straight); anhedonia or the inability to experience pleasure; and diminished emotional expression (essentially an emotional "numbness"). But how many of these problems a person experiences, and how severely, varies enormously. Having one doesn't mean you'll necessarily develop any of the others. © 2013 Guardian News and Media Limited

By JOHN RUDOLF GUATEMALA CITY — DONALD RODAS, a baby-faced man in his late 20s with paranoid schizophrenia, arrived at Guatemala’s only public psychiatric hospital last year after being charged with murdering his parents. He says he often wanders freely through the sprawling facility of dilapidated one-story buildings and wooded courtyards, where detainees charged with crimes mingle with ordinary patients and the developmentally disabled. He sees ugly things. Those who refuse their medication are beaten and put in the “little room,” a barren isolation cell, he said. Desperate women sell their bodies for as little as 5 quetzales, or less than a dollar, to afford basic necessities. “I see when they have sex for money,” Mr. Rodas said in halting English. “To buy food. All they have is beans.” The United States began emptying out its vast asylum system in the 1960s, spurred by scathing reports of abuse and neglect, like a 1946 Life magazine exposé that described many institutions as “little more than concentration camps.” The transition to community-based care cut the institutionalized population by more than 90 percent by 1994. But community care resources failed to match demand in the United States, leading to widespread homelessness and an influx of the mentally ill into jails and prisons. Even so, deinstitutionalization is widely credited with ending the abuse and neglect that made mental institutions synonymous with a nightmarish netherworld. Yet this asylum-based model of mental health care remains the standard across much of the globe. In many poor and developing countries, thousands of mentally ill people are warehoused in dirty and dangerous institutions. Health experts and advocates who monitor such facilities say the picture varies little from country to country: overcrowded wards lacking in privacy; poor sanitation; physical and sexual abuse; routine use of restraints and long-term solitary confinement; and forced treatment, including electroshock without consent. The rights of patients judged to be mentally ill are easily stripped by the courts and are difficult if not impossible to regain. © 2013 The New York Times Company

Anne Trafton, MIT News Office Schizophrenia patients usually suffer from a breakdown of organized thought, often accompanied by delusions or hallucinations. For the first time, MIT neuroscientists have observed the neural activity that appears to produce this disordered thinking. The researchers found that mice lacking the brain protein calcineurin have hyperactive brain-wave oscillations in the hippocampus while resting, and are unable to mentally replay a route they have just run, as normal mice do. Mutations in the gene for calcineurin have previously been found in some schizophrenia patients. Ten years ago, MIT researchers led by Susumu Tonegawa, the Picower Professor of Biology and Neuroscience, created mice lacking the gene for calcineurin in the forebrain; these mice displayed several behavioral symptoms of schizophrenia, including impaired short-term memory, attention deficits, and abnormal social behavior. In the new study, which appears in the Oct. 16 issue of the journal Neuron, Tonegawa and colleagues at the RIKEN-MIT Center for Neural Circuit Genetics at MIT’s Picower Institute for Learning and Memory recorded the electrical activity of individual neurons in the hippocampus of these knockout mice as they ran along a track. Previous studies have shown that in normal mice, “place cells” in the hippocampus, which are linked to specific locations along the track, fire in sequence when the mice take breaks from running the course. This mental replay also occurs when the mice are sleeping. These replays occur in association with very high frequency brain-wave oscillations known as ripple events.

Alison Abbott In a sign that psychiatric-disease research is entering a new era, the pharmaceutical giant Novartis has hired an expert in neural circuitry, rather than pharmacology, to head its relaunched neuroscience division. The appointment of 42-year-old Ricardo Dolmetsch, who has spent his entire career in academic research, signifies a radical policy shift for the company, as it moves away from conventional neurotransmitter research to concentrate on analysing the neural circuitry that causes brain diseases. The decision suggests Novartis is confident that after years of fruitless research in the field, revolutionary advancements in, for example, genetic and stem-cell technologies will pay dividends. The company intends to hire 100 new staff members for the department over the next 3 years. But the move is risky: even if it pans out, new drugs for common disorders such as schizophrenia could be decades away from reaching the market. Dolmetsch, a former senior director at the Allen Institute for brain Science in Seattle, Washington, who has also worked at Stanford University School of Medicine in California, says that his new role gives him access to previously unimaginable resources. “I had this idea that big pharma was a slow, plodding, conservative giant,” he says. “I was surprised by the depth of science at Novartis.” An expert in autism spectrum disorder, he was also attracted by the prospect of contributing to the development of therapies — something that academic institutions are poorly equipped to do — particularly because one of his own sons has autism. There was “not much enthusiasm” for studying disease at the Allen Institute, which focuses instead on basic research into brain science, he says. © 2013 Nature Publishing Group

By T. M. LUHRMANN STANFORD, Calif. — THE specter of violence caused by mental illness keeps raising its head. The Newtown, Conn., school killer may have suffered from the tormenting voices characteristic of schizophrenia; it’s possible that he killed his mother after she was spooked by his strange behavior and tried to institutionalize him. We now know that Aaron Alexis, who killed 12 people at the Washington Navy Yard on Monday, heard voices; many observers assume that he, too, struggled with schizophrenia. To be clear: a vast majority of people with schizophrenia — a disease we popularly associate with violence — never commit violent acts. They are far more likely to be the victims of violence than perpetrators of it. But research shows us that the risk of violence from people with schizophrenia is real — significantly greater than it is in the broader population — and that the risk increases sharply when people have disturbing hallucinations and use street drugs. We also know that many people with schizophrenia hear voices only they can hear. Those voices feel real, spoken by an external, commanding authority. They are often mean and violent. An unsettling question is whether the violent commands from these voices reflect our culture as much as they result from the disease process of the illness. In the past few years I have been working with some colleagues at the Schizophrenia Research Foundation in Chennai, India, to compare the voice-hearing experience of people with schizophrenia in the United States and India. The two groups of patients have much in common. Neither particularly likes hearing voices. Both report hearing mean and sometimes violent commands. But in our sample of 20 comparable cases from each country, the voices heard by patients in Chennai are considerably less violent than those heard by patients in San Mateo, Calif. © 2013 The New York Times Company

By JEREMY W. PETERS and MICHAEL LUO WASHINGTON — Despite deep divisions that have kept Congress from passing new gun safety laws for almost two decades, there is one aspect of gun control on which many Democrats, Republicans and even the National Rifle Association agree: the need to give mental health providers better resources to treat dangerous people and prevent them from buying weapons. Yet efforts to improve the country’s fraying mental health system to help prevent mass shootings have stalled on Capitol Hill, tied up in the broader fight over expanded background checks and limits on weapons sales. Now the shooting at the Washington Navy Yard by a man who authorities say showed telltale signs of psychosis is spurring a push to move ahead with bipartisan mental health policy changes. The new debate over gun control is beginning to turn not on weapons or ammunition, but on the question of whether to spend more money on treating and preventing mental illness. Proponents again face a steep uphill push, but they see an opening even if it remains unclear whether any changes under consideration could have headed off the latest attack, in which the authorities say Aaron Alexis, a former Navy reservist, bought the shotgun he used in Virginia. “Given the clear connection between recent mass shootings and mental illness, the Senate should not delay bipartisan legislation that would help address this issue,” Senators Kelly Ayotte, Republican of New Hampshire, and Mark Begich, Democrat of Alaska, wrote Wednesday in a joint statement to the Senate leadership. The legislation they are pushing, which was held up when a more sweeping gun measure was defeated earlier this year, would establish programs to train teachers to recognize the signs of mental illness and how to defuse potentially violent situations. © 2013 The New York Times Company

By PAULINE W. CHEN, M.D. One afternoon at a school not far from the hospital where I was working, a teacher opened a utility closet and found a staff member passed out on the floor. He was clutching a small bloody mass in one hand, a sharp knife in the other, she reported, a red stain spreading rapidly at his middle. He had amputated his genitals. Once he’d been brought to our emergency room and resuscitated, the man refused further treatment. Doctors and nurses, concerned that if they waited any longer to reattach the severed part the surgery might not work, took the necessary steps to deem him mentally incompetent to make such decisions. “The guy was seriously nuts,” I remember one of the doctors saying afterward. “He kept screaming that he didn’t want ‘it’ back.” For days after the successful operation, the gruesome story was all anyone at the hospital could discuss. Most of us chalked it up to his being “certifiable,” and several wondered if maybe they should have skipped the surgery. “After all,” said one clinician, “isn’t that what he wanted?” But in all the chatter none of us mentioned a key part of the patient’s story: the unbearable suffering that must have pushed him to commit so brutal an act. In fact, anyone overhearing our conversations might have been hard pressed to find any of the warmth and sensitivity we routinely displayed toward patients with cancer, AIDS or heart disease. I remembered the man and our reactions this past week while reading “Falling Into the Fire: A Psychiatrist’s Encounters With the Mind in Crisis,” a thought-provoking new book by Dr. Christine Montross. Of all the afflictions that fall upon us, few remain as misunderstood and stigmatized as those that affect the mind. Copyright 2013 The New York Times Company

By Brian Mossop A fine line separates creativity and madness. Bipolar disorder teeters along that line, with patients experiencing moments of impulsive thought, which can yield bold insights or quickly descend into confusion or rage. In her new book, Haldol and Hyacinths, Iranian-American author and activist Moezzi presents a captivating autobiographical account of her struggle with bipolar disorder. Using a series of vignettes, she reconstructs her downward spiral into psychosis, which eventually led to a suicide attempt and multiple stays in mental health facilities. From seemingly innocuous bouts of insomnia to full-blown hallucinations, Moezzi describes how she descended into madness. Moezzi's medical issues first emerged in her sophomore year of college, when she began to experience severe abdominal pain, later diagnosed as pancreatitis. Doctors decided to remove her pancreas to save her life and prevent a cyst from festering. Everyone she knew rallied alongside her during this time. Things were much different when Moezzi's bipolar disorder took hold in the years following her physical illness. She soon discovered that mental illness has no heroes, no celebrity spokesperson, no champions. Relying solely on the support of her immediate family and a devoted husband, Moezzi saw that the disorder carries a stigma, exacerbated by inaccurate media portrayals. Even worse is the plight of patients in places such as Moezzi's homeland of Iran, where mental illness is simply ignored. Despite bipolar disorder being the sixth leading cause of disability in the world, there is not even a word for the disease in Farsi. © 2013 Scientific American

By Fred Guterl Myths can be more harmful than lies, Nobel laureate Harry Kroto has said, because they are more difficult to recognize and often go unexamined. For many years, a diagnosis of schizophrenia was like a prison sentence, because many people (some of them in the medical profession) held to the notion that a schizophrenic could not recover from the illness and was condemned to an inexorable decline into madness. Like any myth, this one had some truth to it. Many people with severe symptoms do not recover. But some can, as Eleanor Longden discovered for herself. Longden began hearing voices when she was an undergraduate. At first they were somewhat benign, making mostly neutral, factual comments, but they grew more troublesome as she struggled to adjust to college life. Longden was diagnosed as schizophrenic and underwent conventional treatment. By her own account, in “Listening to Voices” in the September/October 2013 issue of Scientific American MIND, the label of schizophrenic and the attitudes of those around her to that label exacerbated her own internal struggles. The voices grew more menacing. Longden began her own slide into madness. But then something odd happened: she began to recover. She did so in part, she says, by accepting the voices in her head as an aspect of her own personality. She listened to them, and tried to understand them. In this way she was able to tame them, and she got enough control over her life to attend school and pursue her graduate studies. © 2013 Scientific American
