Brains Of People With Autism Are More Symmetrical

Do people with autism have differently organized brains? A large-scale MRI study reports fewer differences between the right and left hemispheres in people with an autism spectrum disorder.

Acetaminophen In Pregnancy Linked To Higher Risk Of ADHD, Autism

Exposure to acetaminophen during pregnancy may raise a child’s risk for attention deficit/hyperactivity disorder and autism spectrum disorder, suggests a study from Johns Hopkins University. Researchers analyzed data from the Boston Birth Cohort, a long-term study of factors influencing pregnancy and child development. They collected umbilical cord blood from 996 births and measured the amount […]

First Evidence Of Immune Response Targeting Brain Cells In Autism

The presence of cellular features consistent with an immune response targeting specialized brain cells in more than two thirds of autistic brains analyzed postmortem is reported in a new paper[1]. These cellular characteristics — not previously observed in autism — lend critical new insight into autism’s origins and could pave the way to improved diagnosis […]
