Various presentations including tremor, chorea-ballism, dystonia, athetosis, myoclonus, ataxia, and parkinsonism have been associated with vascular brain lesions [1,2,5,6]. The time course for the development of AIM attributed to stroke is not easily predicted, as the course differs according to the type of AIM; they can manifest with a variety ...

Disorders involving both hyperkinetic and hypokinetic movements can occur following a stroke. Chorea/ballism and dystonia are the most common types of hyperkinetic movement disorders that arise following basal ganglia and thalamic infarctions. Tremor is often develops following thalamic infarction and exhibits extensive cerebellar tract ...

The moyamoya disease is an uncommon cause of vascular chorea, it is an intracranial vasculopathy that evidences an ischemic lesion or, less commonly, hemorrhagic stroke of the basal ganglia . Post-stroke dyskinesia is usually reported as pure movement disorders, but it can be variable, enclosing several components and be difficult to classify ...

Chorea is the commonest movement disorder following stroke and appears in older patients. Involuntary movements tend to persist despite the functional recovery of motor deficit. Deep vascular lesions are more frequent in patients with movement disorders.

Hemichorea and other hyperkinetic movement disorders are a rare presentation of stroke, usually secondary to deep infarctions affecting the basal ganglia and the thalamus. Chorea can also result from lesions limited to the cortex, as shown in recent reports.

Post-stroke hemichorea is an uncommon involuntary hyperkinetic disorder involving unilateral body parts. The incidence and precise lesion location of post-stroke hemichorea remain unclear. The authors describe 27 consecutive patients with hemichorea after stroke.

2011年1月1日 · Patients with vascular-related chorea typically present with an acute or subacute onset of chorea of one side of the body (hemichorea), contralateral to the lesion. Cerebrovascular disease is the most common cause of sporadic chorea. Lesions are most frequently found in the thalamus and lentiform nucleus, and less often in subthalamic nucleus.

Movement disorders occur uncommonly after stroke and include both hyperkinetic and parkinsonian conditions. They can occur at the time of stroke or appear as a later manifestation. Stroke lesions are typically due to small vessel cerebrovascular disease in the middle or posterior cerebral artery territory, vessels supplying the basal ganglia.

2013年6月1日 · Cerebrovascular diseases represent up to 22% of secondary movement disorders, and involuntary movements develop after 1–4% of strokes. Post-stroke movement disorders can manifest in parkinsonism or a wide range of hyperkinetic movement disorders including chorea, ballism, athetosis, dystonia, tremor, myoclonus, stereotypies, and akathisia.

2021年10月29日 · Hemichorea is an uncommon manifestation of acute ischemic stroke [1]. The responsible lesions usually involve deep structures of brain, such as subthalamic nucleus (STN) or striatum, but cortical infarction can also give rise to hemichorea or hemiballismus [1, 2, 3, 4].
