EEGs May Someday Be Able to Diagnose Autism

A readily available brain test could someday be used to diagnose autism in children as young as 2 years old, offering the potential for earlier intervention, according to a new study published online in the journal BMC Medicine.
Researchers at Boston Children's Hospital used electroencephalograms (EEGs), tests that measure electrical activity in the brain, to compare the brains of 430 children with autism and 554 normal children between the ages of 2 and 12.
Children with autism showed reduced connectivity among a number of areas of the brain, and these patterns were different than the patterns observed in normal children.
