Movement disorders are a group of diseases and syndromes affecting the ability to produce and control movement. Though it seems simple and effortless, normal movement in fact requires an astonishingly complex system of control. Movement is produced and coordinated by several interacting brain centers, including the motor cortex, the cerebellum, and a group of structures in the inner portions of the brain called the basal ganglia.
The study area was a large district of Russia with a population of 1,237,900 inhabitants. Multiple sources of case ascertainment were used to identify incident cases of multiple disorders between July 2006 and December 2008. All incident cases were examined by a specialist and followed up prospectively to confirm the diagnosis. The incidence of Western populations and the male-to-female ratio was closer to those reported in studies from Asia.
Deep brain stimulation (DBS) is a surgical technique which is used for the treatment of Movement disorders in which an electrode (an uninsulated wire) is placed in the subcortical (below the surface) structures of the brain. This electrode is connected to a stimulator (a battery) usually placed near the collarbone.
The movement disorders group has defined the technical approach to microelectode-guided DBS implantation for dystonia, resulting in the first American publication on this technique. Another current investigational protocol is examining the use of interventional MRI during DBS, and surgery is performed within an MRI scanner to provide high-quality images of the brain during surgery and allow neurosurgeons to confirm accurate placement of the electrode while minimizing the risk of bleeding complications.
