Dr. Davis is also involved in the clinical trial at Vanderbilt using the implanted Medtronic probe and device for thalmic-stimulation which will reduce drug-resistant essential as well as parkinsonian tremor. Clonazepam-Sensitive Intermittent Dystonic Tremor Thomas L. Davis, MD, P. David Charles, MD, Nashville, TN; and Stanley Burns,MD. ABSTRACT: We report three cases and a literature review describing a syndrome of intermittent idiopathic focal or segmental dystonic tremor dramatically responsive to clonazepam. All patients were young men who had intermittent symptoms. After magnetic resonance imaging of the brain and laboratory analysis of blood, each patient was treated with clonazepam and clinically observed for 1 year. In all three cases clonazepam produced full abatement of the tremor. None of the patients displayed progression of the symptoms, and all have remained tremor free with stable doses of clonazepam. Clonazepam-sensitive intermittent dystonic tremor may represent a benign syndrome occurring in young men. Southern Medical Journal October 95 88;10:1069-71.
