6 パーキンソン病のDBS治療における神経内科医の役割

Deep brain stimulation of subthalamic nucleus (STN-DBS) is currently the most common therapeutic surgical treatment for patients with Parkinson's disease (PD) who have failed medical management. The percentage improvement in Unified Parkinson's disease Rating Scale (UPDRS) part II (activities of daily living) and III (motor) scores was more than 50%. Furthermore, levodopa-induced dyskinesias are dramatically improved because STN stimulation permits an approximately 50% reduction in antiparkinsonian treatment.
How should we decide an appropriate candidate for DBS? It seems that there is a little difference about indication of DBS between neurosurgeons and neurologists.
Since the efficacy of DBS is the improvement in dopaminergic drug-sensitive motor symptoms, we offer surgery to patients only when medical therapy has failed; (1) severe motor fluctuations, (2) severe dyskinesia, (3) tremor uncontrollable by medications, (4) painful dystonia, (5) side-effect for medication (drug-induced psychosis, nausea, vomitting). Taking account of contraindications is important to get successful outcome of the surgery. Dementia, cognitive deficits and psychosis (not drug-induced) are not improved by DBS. When patients are not able to see experienced doctors who manage in programming and dealing with postoperative problems, they are not appropriate candidates. Though benefit to mobility is evident, a risk-benefit assessment should to be made for each patient.
