Consideration of high order brain function after deep brain stimulation for Parkinson disease
Deep brain stimulation, following DBS, is performed for involuntary movements, such as Parkinson disease, idiopathic tremor, so on (see figure). Moreover, it is well-known that some patients show mental disorder or cognitive disorders, such as depression, apathy, so on. However, it is controversial as for the mechanism. We will perform a prospective study as for high order brain function after DBS using various clinical psychological examination and functional imaging (Independent clinical research; 014-0032).
