Thalamic stimulation for primary writing tremor

We report a patient with primary writing tremor whose tremor was treated wi th thalamic stimulation. He had undergone trials of multiple oral medicatio ns with no benefit for his tremor. An electrode lead was implanted in the t halamic nucleus ventralis intermedius with nearly complete control of his t remor and no postoperative complications. We conclude that nucleus ventrali s intermedius thalamic stimulation is safe and effective for primary writin g tremor.
