[A case of hemiballism and a case of senile chorea].

Tiapride is potent on anormal movements. Its utilisation for aged persons seems to have good results. An hemiballism at a woman 83 years old had not regressed very much and the reapprenticeship of walking was possible again. The choreic movements of a woman 90 years old had disappeared and the walk was possible again. These two notes show us the possibilities of improvements in acting obtained even for the very old patients and good tolerance of tiapride.
