Abstract
<strong>Background:</strong> Hemiballism/hemichorea commonly occurs as a result of a lesion in the subthalamic region. <strong>Case Report:</strong> A 38-year-old male with Parkinson’s disease developed intractable hemiballism in his left extremities due to a small lesion that was located adjacent to the right deep brain stimulation (DBS) lead, 10 months after bilateral subthalamic nucleus (STN)-DBS placement. He underwent a right globus pallidus internus (GPi)-DBS lead implantation. GPi-DBS satisfactorily addressed his hemiballism. <strong>Discussion:</strong> This case offered a unique look at basal ganglia physiology in human hemiballism. GPi-DBS is a reasonable therapeutic option for the treatment of medication refractory hemiballism in the setting of Parkinson’s disease.
Highlights
Hemiballism is an involuntary hyperkinetic movement disorder characterized by unilateral, violent, and flinging movements of the limbs[1] and can result from a lesion in the contralateral or ipsilateral subthalamic nucleus (STN), the subthalamic region, the thalamus, and several other brain regions.[2,3,4] Hemiballism is more severe when resulting from an STN lesion than when caused by involvement of other brain regions
We report a unique case where deep brain stimulation (DBS) of the globus pallidus internus (GPi-DBS) was utilized to suppress hemiballism resulting from a subthalamic stroke
We present the details of the case and the physiological recordings from the DBS surgery
