    Mice with a mutation linked to autism affect their littermates’ behavior

    The company mice keep can change their behavior. In some ways, genetically normal littermates behave like mice that carry an autism-related mutation, despite not having the mutation themselves, scientists report.  

    The results, published July 31 in eNeuro, suggest that the social environment influences behavior in complex and important ways, says neuroscientist Alice Luo Clayton of the...

    Most football players who donated their brains to science had traumatic injury

    A majority of football players whose brains were donated for research suffered a degenerative brain disease during their lives, according to the largest sample of players ever studied. The finding provides more evidence that the repetitive injuries to the brain sustained while playing American football are associated with the disease, researchers say.

    Of 202 deceased former football...

    Nerve cell miswiring linked to depression

    Researchers have pinpointed a gene that keeps important brain cells in mice from crossing their wires, providing a possible link between brain wiring and mood disorders like depression.  

    Without the gene, called Pcdhαc2, mice acted more depressed, researchers report April 28 in Science.

    Nerve cells, or neurons, that produce the chemical messenger molecule serotonin extend long...

    Autism, ADHD risk not linked to prenatal exposure to antidepressants

    Taking antidepressants during pregnancy does not increase the risk of autism or attention-deficit/hyperactivity disorder, two new large studies suggest. Genetic or environmental influences, rather than prenatal exposure to the drugs, may have a greater influence on whether a child will develop these disorders. The studies are published online April 18 in JAMA.

    Clinically, the message is...

    Readers question mental health research

    New normal

    People who stay mentally healthy throughout life are exceptions to the rule, a small study suggests. Only 17 percent of study participants experienced no bouts of anxiety, depression or other mental ailments from late childhood to middle age, Bruce Bower reported in “Lasting mental health may be unusual” (SN: 3/4/17, p. 7).

    Reader Lou Floyd found the article disturbing and the...

    Physically abused kids learn to fail at social rules for success

    Physical abuse at home doesn’t just leave kids black and blue. It also bruises their ability to learn how to act at school and elsewhere, contributing to abused children’s well-documented behavior problems.

    Derailment of a basic form of social learning has, for the first time, been linked to these children’s misbehavior years down the line, psychologist Jamie Hanson of the University of...

    Long-lasting mental health isn’t normal

    Abnormal is the new normal in mental health.

    A small, poorly understood segment of the population stays mentally healthy from age 11 to 38, a new study of New Zealanders finds. Everyone else encounters either temporary or long-lasting mental disorders.

    Only 171 of 988 participants, or 17 percent, experienced no anxiety disorders, depression or other mental ailments from late...

    Promise and perils of marijuana deserve more scientific scrutiny

    Marijuana’s medical promise deserves closer, better-funded scientific scrutiny, a new state-of-the-science report concludes.

    The report, released January 12 by the National Academies of Sciences, Engineering and Medicine in Washington, D.C., calls for expanding research on potential medical applications of cannabis and its products, including marijuana and chemical components called...

    Shape-shifting molecule aids memory in fruit flies

    A protein that can switch shapes and accumulate inside brain cells helps fruit flies form and retrieve memories, a new study finds.

    Such shape-shifting is the hallmark move of prions — proteins that can alternate between two forms and aggregate under certain conditions. In fruit flies’ brain cells, clumps of the prionlike protein called Orb2 stores long-lasting memories, report...

    Math offers new view of brain and its disorders

    Of the many disorders that can afflict the brain, schizophrenia and autism are among the most inscrutable. The long scientific searches to explain their causes have turned up many clues and inspired various theories. But no clear answers have emerged.

    A new way of thinking about these disorders has begun to show promise, Laura Sanders reports. This approach conceptualizes the...
