Nearly half of siblings of children with autism have difficulties with attention, language, learning or mood.

The latest estimate of autism prevalence suggests the condition is more common than previously thought, and highlights the complexity in the seemingly simple statistic.

About 1 in 45 children in the U.S. have autism, up 79 percent from the estimate for 2013. But there is more to the apparent jump in diagnoses than meets the eye.

An online portal designed to give researchers easy access to genomic data may unwittingly reveal some sensitive information.

Roughly 13 percent of children with autism eventually lose their diagnosis, either because they outgrow it or because they never had autism to begin with.

Children who have both attention deficit hyperactivity disorder and autism receive their autism diagnosis an average of four years later than those who have autism alone.

By outfitting a child and a clinician with wireless motion sensors, researchers are quantifying the nuances of their social interaction in ways that may aid autism diagnosis.

It took me a while to see that my son had autism. Only then did I recognize the autism in myself.

Clinicians may need to go beyond the ‘masks’ to find autism in women.

It’s past time for mainstream discussions of ‘women with autism’ to recognize that a significant portion of the autistic community identifies as gender-queer or non-binary.
