The authors of “Neurotribes” and “In a Different Key” urge scientists to question their biases and to translate their findings into tangible benefits for those on the spectrum.

A new collection stores genetic and behavioral information about children with autism in inpatient psychiatric units.

Electrically stimulating a particular circuit in the brain shows promise for reversing symptoms of Rett syndrome, a disorder that shares features with autism.

Researchers have defined a new syndrome that results from carrying two mutated copies of CNTNAP2, a gene linked to autism.

Autism is not the only brain disorder that is more common in one sex than in the other.

New evidence implicates the neurotransmitter glycine, which dampens brain signals, in autism.

Autism will cost the U.S. $268 billion this year — a price expected to balloon to $461 billion by 2025.

Researchers have discovered an enzyme that lowers brain levels of FMRP, the protein missing in people with fragile X syndrome. Blocking the enzyme may ease fragile X symptoms in people with the disorder who have low levels of FMRP and mild symptoms.

The social deficits and repetitive behaviors seen in boys with fragile X syndrome seem to stem from their cognitive difficulties, rather than arising independently as they do in autism.

A new mathematical method confidently ranks genes based on their likely impact in a disorder. The approach may help researchers home in on important autism genes.
