  • Title: Hemiballism-hemichorea induced by subcortical ischemia.
    Author: Fukui T, Hasegawa Y, Seriyama S, Takeuchi T, Sugita K, Tsukagoshi H.
    Journal: Can J Neurol Sci; 1993 Nov; 20(4):324-8. PubMed ID: 8313249.
    Abstract:
    Four patients presented with hemiballism-hemichorea as a clinical manifestation of white matter ischemia. These patients illustrate "positive" motor phenomena rather than limb weakness as a consequence of cerebral ischemia. In each patient, the involuntary movements disappeared following worsening of paresis. Subcortical white matter infarction in three patients and hemodynamic hypo-perfusion in the cerebral hemisphere contralateral to dyskinetic movements were possible causes. Neuroradiologically, none had pathological changes in the vicinity of the subthalamic nucleus. We presume from these observations that ischemia of the subcortical white matter, without involvement of the basal ganglia or the subthalamic nucleus, may cause hemiballism-hemichorea.
