Experimental surgeries to prevent seizures may help scientists understand the link between autism and epilepsy.

Brain scans of autistic and non-autistic men reveal an association between white matter aberrations and the ages of their fathers at the time the sons were born.

So far, the only evidence that treatments like this one work is anecdotal.

Independent scientists say the original analysis is flawed; the authors stand by their work and are seeking outside statisticians to reanalyze the data.

An RNA analysis of human brain cells reveals gene expression changes in cortical neurons and microglia linked to autism spectrum disorder (ASD).

Two clinical trials that altered vasopressin signaling report improved social functions in people with autism spectrum disorder, but researchers caution against overinterpreting the results.

Two studies, taken together, imply that sequencing can identify a genetic cause for ultrasound abnormalities in roughly 10 percent of cases.

Signaling imbalance, driven by too much excitatory activity, may be a consequence of whatever brain changes lead to autism rather than a cause of the condition.

Two studies find that connectivity patterns remain stable over time in people with ASD, while in typical subjects they change.
