A neuropsychological disorder related to alterations in
dopamine metabolism and neurotransmission involving frontal-subcortical neuronal circuits. Both multiple motor and one or more vocal
tics need to be present with
tics occurring many times a day, nearly daily, over a period of more than one year. The onset is before age 18 and the disturbance is not due to direct physiological effects of a substance or a general medical condition. The disturbance causes marked distress or significant impairment in social, occupational, or other important areas of functioning. (From DSM-IV, 1994; Neurol Clin 1997 May;15(2):357-79)
