Are there higher occurrences of other mental disorders among individuals with OCD?
Some disorders do appear to be more common among people with OCD. For example, depression and other anxiety disorders (such as generalized anxiety disorder and agoraphobia) occur more commonly in those with OCD. However, some disorders (such as alcoholism, drug abuse, and schizophrenia) do not occur more frequently in those with OCD. In our studies, anorexia nervosa was not associated with OCD, but other studies have shown higher rates of this eating disorder among people with OCD.
