Abstract
The purpose of this study was to assess the influence of age on thalamic deep brain stimulation (DBS) in essential tremor (ET). Tremor, cognition, mood and adverse events in patients with thalamic DBS for ET were evaluated in 26 consecutive patients with established standardized methods for tremor and cognition. Twelve patients <70 and 14 patients ≥70 years were included and followed for 2 years. Clinical outcomes did not differ significantly. DBS seems to be safe and effective for ET independent of age.
