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.

The odds of getting an autism diagnosis depend on where in the United States a person lives.

Isabelle Rapin, a child neurologist who spent more than 50 years working with people with autism, passed away 24 May at the age of 89.

Coaching parents to provide early social stimulation may improve outcomes for children with 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?

Children missing a stretch of DNA on chromosome 16 show worsening motor and social skills in the first eight years of life; those with an extra copy of the region do not show this decline.

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.

Community mental health clinics, which serve millions of Americans, can help identify adults with undiagnosed autism — and change their lives for the better.

Asking parents autism screening questions orally instead of in writing may capture more young Latino children who have the condition.

The vast majority of children flagged for autism on a widely used screening test are never diagnosed with the condition, and some children who are not picked up are diagnosed years later.
