WebHemiballism is caused by a lesion of the subthalamic nucleus on one side of the brain. It is characterised by wild involuntary movements of the contralateral side of the body which may be so large as to prevent patients from feeding or dressing themselves. This is usually caused by a vascular lesion, and often resolves within a few weeks. Web19 Jun 2012 · When it fails (as seen in stroke cases where a lacunar infarct has occurred in the subthalamic nucleus), patients are unable to inhibit unwanted motor patterns, resulting in violent, flinging, involuntary movements of the contralateral hemibody, a condition known as hemiballismus.

Web31 Jan 2024 · Functionally, two additional nuclei are also part of the basal ganglia: subthalamic nuclei substantia nigra Terminology Whilst very widely used in English, the term 'basal ganglia' is actually a misnomer, as a ganglion is a collection of nerve cell bodies outside of the central nervous system. Chronic stimulation of the STN, called deep brain stimulation (DBS), is used to treat patients with Parkinson disease. The first to be stimulated are the terminal arborisations of afferent axons, which modify the activity of subthalamic neurons. However, it has been shown in thalamic slices from mice, that the stimulus also causes nearby astrocytes to release adenosine triphosphate (ATP), a precursor to adenosine (through a catabolic process). In turn, adenosine A1 receptor acti…
