The authors have experimented tiapride in 37 cases of abnormal movements and 20 cases of shaking anxio depresive origin. The best indication of tiapride corresponds to lingual buccal an facial dyskinesia caused by neuroleptics and senile trembling increased by alcoholism. On the other hand its anxiolytic and anti shaking properties are more limited. Finally in the case of degenerative senile trembling its action is less effective. Tolerance to tiapride seemed to be excellent even at high dose.
