[Cases of abnormal movements].

Four patients with abnormal movements were treated with tiapridal. Very good results were obtained in a case of buccofacial dyskinesia associated with an extrapyramidal syndrome and dementia, and in another patient with middle-of-the-dose dyskinesias induced by L-dopa treatment for Parkinson's disease. No effect was observed, however in a case of beginning of the dose dyskinesias, and the extrapyramidal symptoms increased in severity. A dopadecarboxylase-inhibitor was associated with the L-dopa treatment in these three cases. In the fourth case, there was an increase in the spasms of the medial part of the face.
