To The Editor: Kondziolka and coauthors1 make a strong case for Gamma Knife thalamotomy as a noninvasive therapeutic option for patients with severe tremor who are not candidates for or who choose not to undergo surgical procedures such as deep brain stimulation or radiofrequency ablation (Kooshkabadi A, Lunsford LD, Tonetti D, et al: Gamma Knife thalamotomy for tremor in the magnetic resonance imaging era. Clinical article. J Neurosurg 118:713–718, April 2013). Furthermore, they suggest that this option fulfills an unmet clinical need and is under-utilized.
