Signs & Symptoms

Emotion control eludes more girls than boys with autism, according to a new study of young people hospitalized for psychiatric issues.

A study that followed 126 autistic people in England from their preteen years to age 23 found little improvement in their behavioral and emotional problems.

Standardized tests can reliably assess memory, language ability, executive function and other traits in people with intellectual disability linked to autism.

Toddlers who sleep poorly or overreact or underreact to sensory stimuli have more repetitive behaviors and other autism traits later in childhood.

In younger siblings of children with autism, insecure attachments to their caregivers increases the odds of being diagnosed with autism.

Some people with autism have an unusually large head. What causes the enlargement? And does it have any bearing on outcome?

Individuals with mutations in an autism gene called TRIO may have a range of conditions, including intellectual disability and anomalous head size.

A short, widely used screening survey for autism called the AQ-10 may not be reliable for measuring traits of the condition in the general population.
