[Abnormal movements of vascular origin].
Three patients with hemichorea and ten with dystonia of vascular origin are reported. Five were secondary to ischemic infarcts, two to lacunar infarcts, three to intraparenchymal hematoma, and in the remaining three the type of lesion could not be determined. The patients with chorea, as opposed to those with dystonia, presented abruptly immediately after the stroke, and had a regressive evolution and good therapeutic response. The type of dyskinesia was not useful to identify the precise localization of the lesion or to determine its nature. In addition, in 5 patients multiple lesions were found and 5 had release of archaic reflexes or cortical atrophy in CT; this shows the importance of the overall functional impairment and focal lesions in the genesis of dyskinesia. There were sensory deficits in 7 patients. In 2 patients lesions were not found in the CT in spite of the presence of previous hemiparesis; this suggests that this technique has limitations to discover focal cerebral lesions in patients with focal or hemicorporal dyskinesia.
