Maternal antibodies that attack fetal brain proteins could underlie some cases of autism, says immunologist Betty Diamond.

Autism and attention deficit hyperactivity disorder show genetic and neurobiological overlap, which may provide clues to the origin of both disorders, says Joel Nigg.

Clinicians and autism researchers should learn the early signs of autism and take into account an individual’s developmental trajectory, says Tony Charman.

Blood from individuals with autism could help researchers identify biomarkers to diagnose the disorder and learn more about related symptoms, such as gastrointestinal complaints, says molecular biologist Valerie Hu.

Studying the cellular and molecular mechanisms that underlie autism is crucial to advancing our understanding of the disorder, says neuroscientist Eric Kandel.
