Approximately five million people in the U.S., or about one in every 50 Americans, suffer from OCD. That’s about 2%, a substantial number of sufferers. It affects men, women, and children, as well as people of all races, religions, and socioeconomic backgrounds. OCD is an anxiety disorder characterized by symptoms that can include powerful, unwanted, or recurrent thoughts and/or compulsive, repetitive behaviors. Some of the most common obsessions are:

Some people who are familiar with TS may think of people shaking wildly of cursing a lot, but that is only in a severe case.
