Some children diagnosed with autism by age 2 show unusual responses to sights, sounds and textures as infants.

Some autistic children don’t show traits of the condition until age 5 or later.

Autism and schizophrenia co-occur significantly more often than would be expected by chance, according to an analysis of nearly 2 million people.

Adding motor and sensory data boosts the accuracy of Research Domain Criteria — a broad research framework adopted by the U.S. National Institute of Mental Health — for predicting autism.

The rising prevalence of autism is not leveling off, according to a new study that accounts for every diagnosis made in Denmark over 32 years.

New and improved autism screens and diagnostic tools promise to streamline the long path to an autism diagnosis.

A recalibrated version of a widely used test for autism may accurately reflect autistic children’s development as they grow and become verbal.
