OCD Risk Higher When Several Variations In Gene Occur Together
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.
OCD, an anxiety disorder, affects an estimated 2.2 million Americans age 18 or older. Symptoms usually begin sometime between childhood and early adulthood.
