  ABSTRACT: Hemiballismus has traditionally been linked to lesions in the subthalamic nucleus. We studied six patients with hemiballismus presumably caused by ischaemic stroke. They were followed for up to two years. Cerebral MRI with special projections showed that four out of six patients had ischaemic lesions in other parts of the brain than the subthalamic nucleus. Knowledge of the basalganglio-thalamocortical circuits is used to try to explain the cause of hemiballismus. Neuroleptics and benzodiazepines are the usual medical treatment for hemiballism and were helpful also in our patients. The prognosis in hemiballismus is good; four of our six patients had spontaneous recovery within nine months. The prognosis was not related to the site of the lesion.

  ABSTRACT: The aim of this study was to evaluate neurological clinical findings and cerebral computed tomography (CT) findings in patients with acute stroke within six hours after stroke onset. 42 patients with presumed stroke in the middle cerebral artery territory were clinically assessed with the Scandinavian Stroke Scale Score. CT scans were assessed in a standardized manner by one neuroradiologist. The clinical deficit did not forecast the CT findings. Patients with several early CT signs of ischaemia, and especially those with hypodensity in less than one third of the middle cerebral artery area had lower clinical scores than patients with fewer signs. Hypodensity in the insular region was the overall most frequent finding. Clinical findings do not give definite information about the ischaemic damage in the acute phase of cerebral infarction. CT scans may give valuable information primarily when there are positive findings.
