Shared neurological factors in autism, ADHD, and obsessive compulsive disorder

New research published in the American Journal of Psychiatry has found shared irregularities in brain activity across autism spectrum disorder (ASD), obsessive compulsive disorder (OCD) and attention deficit hyperactivity disorder (ADHD). Similar tendencies – including impulsivity, difficulties in emotional regulation and a preference for routine – can be observed in all three disorders, and a recent study of 200 children has indicated that unusual activity in the corpus callosum, the pathway responsible for communication between the right and left sides of the brain, may be the root of these shared behaviours. In particular, the study highlighted a link between disruption in the corpus callosum and ASD, ADHD, and OCD children’s difficulties with independence in everyday tasks.
