Overview Symptoms Treatment Prevention

Chronic motor tic disorder

• Vocalizations (grunts, throat clearing, abdominal or diaphragmatic contractions)
• Facial grimacing
• Excessive blinking
• Rapid, recurrent movement of the arms, legs, or other areas

These symptoms (or any combination of them present in an affected person) can be voluntarily suppressed for a relatively brief length of time. A sensation of relief is experienced when these movements have been carried out. Tics can also be suggestible, may persist during all stages of sleep, and may exacerbate with stress, heat, excitement, and fatigue.

Diagnosis of a tic is generally made during physical examination. No tests are usually necessary.
