In Japan, the first case of DBS for controlling central pain syndrome was experienced in 1979 and DBS of the thalamic nucleus ventralis caudalis and periaqueductal gray matter have been used for pain control for many years. Neurosurgeons also initiated a clinical trial of DBS for controlling movement disorders, such as tremor, Parkinson’s disease (PD) and dystonia. Our government approved DBS to be covered by the public insurance system for pain control in 1992 and for movement disorders in 2000. In particular, DBS for subthalamic nucleus (STN) is currently the most common therapeutic surgical procedure for patients with PD. The long-lasting beneficial effects of STN-DBS on motor function have now largely been acknowledged. However, behavioral and/or psychiatric changes have been demonstrated in certain case reports and case series. DBS is also a successful therapeutic option for patients with primary dystonia and tremor syndrome who do not respond sufficiently to conservative therapies. The most common target of DBS in patients with dystonia is the internal region of the globus pallidus (GPi). GPi-DBS leads to long-lasting and remarkable improvement of dystonic movements in majority of patients. In Parkinson’s tremor or post-stroke movement disorder, the intermediate ventral nucleus of the thalamus (Vim) and the subthalamic region have proven to be promising targets for DBS electrodes. Especially in patients with essential tremor, Vim-DBS leads to an acute reduction of the tremor. In addition, DBS is beginning to be used as a new therapeutic procedure for psychiatric diseases, such as depression and obsessive-compulsive neurosis in many countries. We will summarize our experiences and previous reports, and discuss the mechanism and future perspectives for DBS in the management of central nervous system disorders.
