Tics are sudden twitches, movements, or sounds that people do repeatedly. People who have tics cannot stop their body from doing these things. For example, a person with a motor tic might keep blinking over and over again. Or, a person with a vocal tic might make a grunting sound unwillingly. The tic disorders differ from each other in terms of the type of tic present motor or vocal, or a combination of both , and how long the symptoms have lasted. People with TS have both motor and vocal tics, and have had tic symptoms for at least 1 year.

Blinking, twitching of the facial muscles or repetitive mouth movements all fall under the classifications of tics. Some children experience these tics as part of childhood development. The New York times reports that as many as one-quarter of all children experience facial tics. These transient tics go away on their own with time, according to the University of Maryland Medical Center. Stress can contribute to tics, so doctors advise against calling attention to tics or nagging a person about them. The New York Times reports that reducing stress in the environment can reduce tics and help them to go away altogether. Your doctor may prescribe risperidone or pimozide.

Tics are brief movements or sounds that resemble voluntary actions, but appear suddenly, without regularity, often exaggerated in intensity and are repetitive and inopportune to social context. Tics also lack behavioral flexibility, which is a characteristic marker for voluntary actions and defines normal human goal-directed behavior.
Tics are defined as repeated, sudden, rapid, nonrhythmic muscle movements including sounds or vocalizations. Diagnosis is clinical. Tics are treated only if they interfere with a child's activities or self-image; treatment may include cognitive-behavioral therapy and clonidine or an antipsychotic. Male to female ratio is Tics begin before age 18 yr typically between ages 4 yr and 6 yr ; they increase in severity to a peak at about age 10 to 12 yr and decrease during adolescence.
