Gilles de la Tourette's syndrome: report of five cases in the Chinese.

Five cases of Gilles de la Tourette's syndrome occurring in the Chinese are described. The onset, course, symptomatology and family psychopathology are similar to those reported in Caucasians. On the parameters of APGAR score, psychological testing, EEG and psychiatric examination all had at least one abnormality. The response to haloperidol was uniformly good. Follow-up results showed that all were able to lead a fairly normal life after treatment. Though the cases are few in number, the findings seem to support the hypothesis that the syndrome has an organic substratum subject to psychological influences.
