The loss of abilities that besets some toddlers with autism is probably less sudden and more common than anyone thought.

Autism and schizophrenia share a long and tangled history. Comparing the social features of the two conditions could lead to better treatments and a deeper understanding of each.

After a decade of fast-paced discovery, researchers are racing toward bigger datasets, more genes and a deeper understanding of the biology of autism.

Children with autism are often clumsy, physically awkward or uncoordinated. This understudied and nearly ubiquitous feature has researchers contemplating a new idea: Could motor problems be one source of autism’s social difficulties?

Having autism as a parent might seem impossibly challenging. But a generation of parents with the condition is showing that it can be an advantage — even when their child does not share the diagnosis.

People with autism fall in love. They marry. They even (gasp) have sex. Yet these deeply human needs have mostly gone ignored by scientists.

Many people on the spectrum take multiple medications — which can lead to serious side effects and may not even be effective.

Young adults with autism face many new expectations and challenges — with none of the support that is available during high school.

Mice have long been the mainstay of autism research, but a small group of scientists say rats are the superior choice. Rats are bigger, smarter, friendlier — and a lot more fun.

Conventional wisdom holds that people with autism don’t get hooked on alcohol or other drugs, but new evidence suggests otherwise.
