(HealthDay News) -- Nearly one in 50 American adults has obsessive-compulsive disorder (OCD).
OCD is characterized by an unusually high level of concern or anxiety about a particular subject. It's believed to be caused by a brain abnormality that affects the way information is processed.
OCD can affect people of all ages, and studies have found a genetic link to the disorder. People with OCD may obsess about things like cleanliness, or be convinced of an accident or harm to a friend or family member.
According to the Obsessive-Compulsive Foundation, an antidepressant is typically used to treat OCD. Your doctor may also recommend behavioral therapy or counseling to help treat the disorder and minimize symptoms.
