Tic Disorders

Tics and twitches are spasm-like movements of particular muscles that often affect the face or eyelids but can occur anywhere in the body. While typically harmless and temporary, they may be caused by a tic disorder. The two types of tics – motor tics and vocal tics – occur suddenly and are often repetitive. Twitches differ from tics in that they are isolated occurrences and not repeated actions. These disorders can generally be managed with a combination of treatment and lifestyle changes.
