|Tic disorders cause rapid, uncontrollable movements or sounds that a person makes for no apparent reason. They are involuntary actions and often tend to happen in sudden bouts. Usually occurring on a daily basis, tics are almost always an unwelcome experience for the sufferer.
People with tics may succeed in suppressing them for a short time, but most often not long- term. They are as difficult to suppress as the urge to sneeze! Like the sneeze, it can be very uncomfortable to suppress a tic, and many people describe a feeling of relief afterwards.
