Abstract
|

|
|
Classic essential tremor (ET) is a condition in which the upper extremities, and, less commonly, the head, face, voice, trunk, and lower limbs, exhibit a mixed postural and kinetic tremor without other neurologic abnormalities. Most patients with ET probably inherit the disease through an autosomal dominant genetic mutation, but the true ratio of hereditary versus sporadic ET is unknown. The diagnosis is clinical, and pharmacologic and surgical therapies exist. Currently, there are 4 effective surgical treatments for patients with ET. Most surgical interventions target the ventral intermediate nucleus of the thalamus and the adjacent ventral white matter tracts. The purpose of this review is to present the existing literature regarding outcomes of the 4 commonly performed surgical treatments for ET?(1) deep brain stimulation, (2) radiofrequency thalamotomy, (3) Gamma Knife radiosurgical thalamotomy and (4) focused ultrasound thalamotomy?and to compare the procedures. Gamma knife radiosurgery is well established for geriatric patients.
