Stereotactic neurosurgery for tremor



The role of the motor thalamus as surgical target in stereotactic neurosurgery for different kinds of tremor is discussed. For tremor in Parkinson's disease, the subthalamic nucleus becomes more and more often the surgical target, because this target also gives relief of other and more incapacitating symptoms (hypokinesia, rigidity). Stimulation is as effective in tremor suppression as coagulation but has less adverse events and permits bilateral surgery. In selected cases, thalamotomy can still be indicated. © 2002 Movement Disorder Society
