“Tics are the most varied of all movement disorders.
Tics are brief and intermittent movements (
motor tics) or sounds (phonic
tics).
Motor tics typically consist of sudden, abrupt, transitory, often repetitive, and coordinated movements that may resemble gestures and mimic fragments of normal behavior, vary in intensity, and repeated at irregular intervals. The movements are most often brief and jerky however, slower, more prolonged movements also occur.
