Obsessive – Compulsive Disorders The most common kinds of OCD behaviors: checking ,counting, collecting . These are all basic natural behaviors . Accompanied by intense anxiety and inability to inhibit the behavior. "I couldn't do anything without rituals. They invaded every aspect of my life. Counting really bogged me down. I would wash my hair three times as opposed to once because three was a good luck number and one wasn't. It took me longer to read because I'd count the lines in a paragraph. When I set my alarm at night, I had to set it to a number that wouldn't add up to a "bad" number. "Getting dressed in the morning was tough because I had a routine, and if I didn't follow the routine, I'd get anxious and would have to get dressed again. I always worried that if I didn't do something, my parents were going to die. I'd have these terrible thoughts of harming my parents. That was completely irrational, but the thoughts triggered more anxiety and more senseless behavior. Because of the time I spent on rituals, I was unable to do a lot of things that were important to me.”

ABA: Treating Tourette’s Syndrome With Habit-Reversal Therapy Analysis of the problem: a ‘positive feedback loop’. “Patients feel the need to tic and then experience relief when they do, thus reinforcing the neural circuits involved in that behavior.” Train patients to “replace the tic with a competing response.” Try to disrupt the “automatic chain of events underlying the expression of a tic.” This is effective.
