For researchers who work with study participants in person, lockdowns made it impossible to obtain fresh data, a survey finds.

The review of more than two dozen studies finds aripiprazole has side effects and does not change core autism features, but parents report improvements in self-injury, tantrums, and other challenging behaviors.

Five collaborations involving autistic scientists and experts are advancing autism research, from lending support for theories of the condition to shoring up trials of new treatments.

Conversations between the immune and central nervous systems are proving to be essential for the healthy social behavior, learning, and memory.

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

A large twin study in Sweden finds genetics has a much larger influence on the odds of an autism diagnosis, and has remained consistent over time.

An accumulation of T cells and astrocytes in postmortem brain tissue hints at possible autoimmune origins for many cases of autism.

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.
