Obsessive-Compulsive Disorder (OCD)|
Obsessive-compulsive disorder (OCD) is an illness that causes people to have unwanted thoughts (obsessions) and repeat certain behaviors (compulsions). People with OCD create habits that interfere with their daily lives.
There is no single proven cause of OCD, but research suggests that OCD stems from problems with the communication between the front part of the brain and the deeper structures. These brain structures use the chemical messenger serotonin, whose low levels are believed to be responsible for OCD. OCD is treatable, often by drugs that raise these serotonin levels. OCD may also be associated with other types of anxiety, like panic attacks and phobias. If you or a loved one has the symptoms of OCD, talk with your doctor.
