Abstract
Tremor research during the past year has focused on clinical differential diagnosis, and a new clinical classification has been developed. The origin of tremor is thought to depend on unstable central loops, and new coherence data suggest that these often involve the motor cortex. Gabapentine has been assessed for efficacy in some tremors, and deep brain stimulation of the ventrolateral thalamus has been shown to be safer and more effective for severe essential and parkinsonian tremor than thalamotomy.
