Tourette syndrome
Background
Tourette syndrome: Gilles de la Tourette syndrome
This is a condition characterised by multiple tics. Tics are involuntary twitch-like movements involving groups of muscles. In this syndrome, tics characteristically involve the facial area (e.g. blinking, grimacing, nodding) as well as phonic (vocal) tics, although any area can be involved. The tics range from very simple to more complex, purposeful movements. Vocal tics can be as simple as throat clearing or coughing. Tics can be suppressed for a short time and so, for example, the condition may appear different at school compared to home.
