Spectrum spoke with three Black scientists about why they got into autism research, what keeps them excited about their work and how the field could become more diverse.

Genetic variants that contribute to autism may also be involved in attention deficit hyperactivity disorder and Tourette syndrome, according to a new study.

Gene therapies and the factors influencing autism traits top Spectrum’s list of the 10 most notable research findings we covered in 2020.

Genetic sequences from nearly 53,000 people with autism, developmental delay or intellectual disability reveal strong ties to 98 genes.

People who have large mutations associated with autism and schizophrenia share atypical patterns of brain connectivity, according to a new study, especially between areas that process sensory information.
