Abstract

Stereotactic ventral intermediate nucleus (Vim) thalamotomy may improve drug resistant severe parkinsonian tremor. However, tremor may recur and bilateral thalamotomy is known to induce unacceptable side effects in a proportion of patients. A high frequency (130 Hz) chronic Vim stimulation was performed in 4 parkinsonian patients, 2 of them having previously undergone a thalamotomy on the other side. Tremor was suppressed in all patients at the price of slight paresthesias. This improvement has been lasting from 2 to 14 months. Beneficial and adverse effects were suppressed at once each time the stimulation was stopped. These preliminary results are encouraging but a longer delay and more patients are obviously needed.
