Strep infection in pregnant rats causes autism features in pups

by  /  18 November 2014

Infection with group B streptococcus bacteria in pregnant rats triggers brain abnormalities and autism-like behaviors in their pups — especially in males. Researchers presented the unpublished results today at the 2014 Society for Neuroscience annual meeting in Washington, D.C.

Scientists catalog effects of PTEN mutations in autism

by  /  27 October 2014

People with autism who have mutations in a gene called PTEN have a distinct profile of cognitive impairments and structural abnormalities in the brain. The profile, published 7 October in Molecular Psychiatry, points to a subtype of autism with these features.

Common brain malformation confers high risk for autism

by  /  29 May 2014

About one in every three adults who lack a brain structure called the corpus callosum meet the diagnostic criteria for autism, according to a study published 25 April in Brain. However, not all of these people develop symptoms in early childhood, as is typical in autism.

Molecular mechanisms: Mice link brain region to autism

by  /  21 May 2013

A strain of mice with autism-like behaviors is missing a corpus callosum, a bundle of nerve fibers that connects the two hemispheres of the brain. Two studies published this month investigate the link between these two features.
