One in five children in the United States have a psychiatric condition, but schools often lack the training and resources they need to give these students the support they need.

Mental health conditions crop up more than twice as often in families that include a child with autism as in the general population.

Researchers are studying more than 1,000 postmortem brains with the goal of unearthing shared genetic roots in neuropsychiatric conditions, including autism.

Left to languish in psychiatric institutions or drugged for disorders they never had, many older adults with autism were neglected or forgotten for decades. Efforts to help them are finally underway.

Autism is not the only brain disorder that is more common in one sex than in the other.

DNA sequences called enhancers — which boost the expression of genes from within or outside them — are enriched for genetic variants linked to autism, suggests a new study. The finding may help researchers understand how variants outside genes contribute to autism.

An ancient drug eases symptoms of fragile X syndrome in mice, and “The Imitation Game” draws ire over an autism innuendo.

The configuration of methyl groups that modify DNA in sperm change as men get older. These alterations may help explain why children of older fathers are at increased risk for neuropsychiatric disorders such as autism.

Severe mental illness such as schizophrenia or bipolar disorder in a parent significantly ups autism risk.

Adults with autism may suffer from various health problems, ranging from psychiatric conditions to motor symptoms that resemble Parkinson’s disease, according to two studies presented Thursday at the 2014 International Meeting for Autism Research in Atlanta.
