Adding Psychotherapy to Medication Treatment Improves Outcomes in Pediatric OCD

Science Update • September 21, 2011
Youth with obsessive compulsive disorder (OCD) who are already taking antidepressant medication benefit by adding a type of psychotherapy called cognitive behavior therapy (CBT), according to an NIMH-funded study published September 21, 2011, in the Journal of the American Medical Association.

Mice with Autism-related Mutations Replicate Autism-like Behaviors

Science Update • April 15, 2011
Mice bred to harbor mutations similar to those discovered in people with autism show autism-like repetitive behaviors and social impairments. The behaviors, triggered by deletions in a gene called SHANK3, implicated in some cases of autism, were traced to weak neural connections for functions disturbed in autism.

Silenced Gene for Social Behavior Found in Autism

Science Update • December 03, 2009
For the first time, inherited disruption of gene expression in a brain system for social behavior has been implicated in autism. NIMH grantee Margaret Pericak-Vance, Ph.D., at the University of Miami and Simon Gregory, Ph.D., at Duke University, and a multinational team of researchers found evidence for such epigenetic effects on the gene for the oxytocin receptor -- part of a brain system that mediates social behaviors disturbed in autism. The findings suggest a potential genetic biomarker for the disorder.

Journal Highlights Effectiveness of Research Based Psychotherapies for Youth

Science Update • April 15, 2008
Reviews of the current research on psychosocial and behavioral therapies, or psychotherapies, for children and adolescents found a number of "well established" and "probably efficacious" treatments for many mental disorders. For example, six were "probably efficacious" for anxiety disorders, and two were "well established" for attention deficit hyperactivity disorder (ADHD), according to scientists funded by NIMH and the National Institute on Drug Abuse, divisions of the National Institutes of Health.

OCD Risk Higher When Several Variations in Gene Occur Together

Science Update • April 07, 2008
Several variations within the same gene act together to raise the risk of obsessive-compulsive disorder (OCD), new NIMH research suggests. The gene produces a protein that helps make the brain chemical serotonin available to brain cells.
