Hearing difficulties and autism often overlap, exacerbating autism traits and complicating diagnoses.

Nearly all genes with moderate to strong ties to autism are expressed in the developing amygdala; a few show altered expression in the amygdalae of autistic people.

Having an autistic brother or sister can pose challenges, but it can also make children patient, empathetic and resilient.

Grouping autistic people based on their social abilities may reveal subtypes of the condition.

Growing ranks of researchers on the spectrum are overcoming barriers — from neurotypical bias to sensory sensitivities — to shape autism science.

Children with social difficulties are more likely than those without to develop problems with eating by age 14.

The overproduction of proteins in brain cells called microglia causes social impairments, cognitive deficits and repetitive behavior in male mice, a new study has found.

Isolated from their peers, some autistic men get drawn into extremist views — and, in rare cases, violence — associated with online groups for ‘celibates.’

Mice missing DLG2, a protein central to neuronal activity, are anxious, sleep poorly and overgroom themselves.

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.
