“…Moreover, hemiballism predominantly in one leg caused by an isolated haemorrhage of the STN is very rare. Ohnishi12 and Maruyama et al 13 reported cases of patients with ballism confined to the contralateral leg, so-called monoballism. In the case reported by Ohnishi, a 62-year-old man developed monoballism in his right lower limb.…”

Hemiballism is a rare movement disorder characterised by high-amplitude movements of the limbs on one side of the body. Stroke of the contralateral basal ganglia, especially the subthalamic nucleus (STN) is the most common aetiology of acute development of hemiballism. Recently, the pathophysiology of hemiballism has been associated with abnormal firing patterns in the globus pallidus interna, with intermittent firing bursts followed by pauses, during which movements occur. An 87-year-old woman presented with a 5-day history of hemiballism predominantly in her leg. On the basis of her brain MRI findings, she was diagnosed as having vascular hemiballism caused by haemorrhage in the contralateral STN. Treatment with risperidone led to the clinical resolution of her condition. We discuss the distribution of the patient's ballistic movements on the basis of the somatotopic organisation of the STN.

Postmortem analysis of bilateral subthalamic electrode implants in Parkinson's disease

et al. 2002

This is the second neuropathological report detailing bilateral electrodes targeting the subthalamic nucleus (STN) in idiopathic Parkinson's disease (PD). The patient presented with unilateral tremor-dominant parkinsonism. Bilateral STN stimulation was carried out 7 years later due to significant disease progression and severe motor fluctuations. The patient exhibited bilateral improvements in rigidity and bradykinesia both intraoperatively and postoperatively. The patient died 2 months later from aspiration pneumonia. Neuropathological examination confirmed both the diagnosis of PD and the electrode placements. The tip of the left electrode was located medially and posteriorly in the left STN and the tip of the right electrode entered the base of the thalamus/zona incerta immediately above the right STN. Tissue changes associated with the subthalamic electrode tracts included mild cell loss, astrogliosis, and some tissue vacuolation. Our postmortem analysis indicates little tissue damage associated with STN stimulation for PD.
