Tics are brief, suppressible, nonrhythmic, stereotyped abnormal movements; blinking, and throat clearing are typical, but tics can be more complex. Transient tics are common, and tics persist for at least a year in ~3% of all children. The differential diagnosis is broad, but most tics are relatively benign. Effective treatments are available.
