Original abstract
arkinson disease (PD) is the second most common degenerative disease in the central nervous system following the Alzheimer's disease. Although the specific progressive degenerative change of dopamineproducing cells in the substantia nigra compacta has been well documented, neither the cause nor the underlying mechanism of degeneration has been identified. Longterm use of Ldopa causes dyskinesia, motor fluctuation, and other side effects, preventing the patients with advanced PD from further medication. Since deep brain stimulation (DBS) was introduced in the late 1980s by Dr. Benabid, it has become the standard surgical treatment for the patient with advanced PD who has developed drug-induced side effects or motor fluctuation after longterm use of Ldopa. Since DBS had been first reimbursed by the National Health Insurance System in January 2005 in Korea, many patients with advanced PD had a chance to be treated with DBS. The subthalamic nucleus (STN), globus pallidus interna (GPi), and thalamic VIM nucleus have been utilized as the target of DBS in the treatment of the patients with advanced PD. In this paper, the author briefly reviews the current methodology of surgical treatment of advanced PD, focusing on the STN DBS. Abstract
