Obsessive-compulsive disorder, or OCD, is one of the most common anxiety disorders. OCD causes one to attempt to manage their fears, thoughts, and worries through sets of small rituals. OCD can cause disturbing images and thoughts that lead to increased anxiety. Although no one knows the exact cause, most experts believe a combination of brain abnormalities, genetics, and a person’s environment leads to OCD. People suffering from OCD often have a fixation on cleanliness, with a strong dislike for germs. They tend to be very neat, wanting things in a specific order. Harsher symptoms can excessive touching and counting, as well as, thoughts of violence and disturbing sexual acts. A variety of treatments can be drafted based on the person and their level of mental discomfort.
