A case report of complete disappearance of essential tremor after Gamma Knife radiosurgery.

Pharmacological therapy for essential tremor (ET), the most common movement disorder, remains largely unsatisfactory. Surgical options such as radiofrequency or thermocoagulation are only suitable for a select group of patients, the young and those free of pre-existing medical conditions. Radiosurgery using the Leksell Gamma Knife has recently gained acceptance as a viable treatment option for tremor control in ET patients. We describe our experience with the first reported ET patient treated with radiosurgery in Louisiana.
