Case reports suggest electroconvulsive therapy is effective for treating catatonia in people with autism.

Mice lacking one copy of a gene linked to autism are small and show striking changes in the number and quality of their cries.

A top autism gene called SCN2A plays a role at neuronal connections into adulthood, offering hope for treating mutations after infancy.

The U.S. Drug Enforcement Agency has made it legal for doctors to prescribe an epilepsy drug derived from marijuana. But all other compounds derived from marijuana remain under tight restrictions.

A new brain implant pumps chemical signals directly into a target region to ease seizure-like activity in mice.
