[Stereotactic operation for Parkinson's disease].
The aim of stereotactic operation for Parkinson's disease is to improve or keep daily activity or quality of life by ablation or improvement of some parkinsonian symptoms. All of parkinsonian symptoms are not improved by stereotactic operation and classify roughly into three categories. The symptoms which are definitely improved are tremor, rigidity, L-dopa-induced dyskinesia, bradykinesia (secondary bradykinesia caused by rigidity) and wearing off phenomenon. Freezing gait, postural instability or postural abnormality is improved in some patients, but not always. Disturbance of speech or swallowing, L-dopa non-responsive akinesia, psychiatric symptoms or autonomic disturbances are not expected to be improved. Before stereotactic operation symptoms which cause disabilities of patients should be carefully examined. Aim of stereotactic operation should make clear and not ambiguous.
