Mice with Autism-related Mutations Replicate Autism-like Behaviors

Science Update

mouse synapses

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

epigenetic mechanism

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

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

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.

Gene Triggers Obsessive Compulsive Disorder-Like Syndrome in Mice

Press Release

Using genetic engineering, researchers have created an obsessive-compulsive disorder (OCD) - like set of behaviors in mice and reversed them with antidepressants and genetic targeting of a key brain circuit. The study, by National Institutes of Health (NIH) -funded researchers, suggests new strategies for treating the disorder.

Mutant Gene Linked to Obsessive Compulsive Disorder

Press Release

Analysis of DNA samples from patients with obsessive compulsive disorder (OCD) and related illnesses suggests that these neuropsychiatric disorders affecting mood and behavior are associated with an uncommon mutant, malfunctioning gene that leads to faulty transporter function and regulation.
