Deep brain stimulation of the centromedian thalamic nucleus for essential tremor: a case report.

The centromedian nucleus (CM) of the thalamus is an important site with anatomical connections to different cortical and subcortical motor areas; however, its role in tremor disorders is not clear, although deep brain stimulation (DBS) of the CM has been described to be effective in the treatment of parkinsonian tremor. We report a case of a patient with medication-refractory essential tremor (ET) who had excellent tremor suppression with DBS of the CM. The CM and the nearby region should be explored as a potential target for the treatment of ET and other forms of tremor.
