Atypical patterns of neuronal activity and gene expression in the striatum may characterize autism in girls, according to a new study.

Federal funding for autism research increased by $23.2 million from 2016 to 2018, according to the latest report from the Interagency Autism Coordinating Committee.

The more scientists dig into DNA, the more intricate its contribution to autism seems to be. Here, we unravel the complex genetics of autism.

Elizabeth Berry-Kravis has spent decades uncovering molecular clues to fragile X syndrome and crafting trials of treatments. Her efforts are paying off.

The recognition of autism independently at different times and across different cultures shows the condition has clear boundaries, despite considerable heterogeneity.

Next-generation machine-learning tools are poised to upend how scientists study behavior in animal models of autism — and not everyone is happy about it.

Autistic boys and men show notable differences in brain development, according to magnetic resonance imaging scans taken over a 16-year period.

Researchers have uncovered more than 1,200 new protein-protein interactions involving proteins coded for by autism-linked genes.

Children with autism traits tend to show agitation, excitability, decreased sleep and other mild signs of mania in adolescence; the association is higher in identical twins than fraternal twins, suggesting that genetics plays a role.

Multiple types of bias and an overreliance on caregiver reports have clouded research on the effectiveness of early interventions for autism for nearly three decades.
