Deep brain stimulation as an effective treatment option for post-midbrain infarction-related tremor as it presents...

Benedikt syndrome is a rare but debilitating constellation of symptoms that manifests from infarction of the red nucleus, cerebral peduncle, oculomotor fascicles, and lower oculomotor nucleus. Clinically, it presents as ipsilateral cranial nerve III palsy, contralateral hemiataxia with intention tremor, contralateral hemiparesis, and hyperactive tendon reflexes. Commonly, the tremor upon purposeful movement proves to be the most debilitating manifestation of the infarction with significant impact on the patient's ability to perform activities of daily living and, therefore, quality of life. The authors report the successful management of this debilitating post-midbrain infarction tremor with the insertion of a deep brain stimulator with targets in the contralateral lenticular fasciculus.
