Movement disorders: Current understanding of pathophysiology and management

In the last four decades, great strides have been made in understanding the pathophysiology and management of movement disorders. Several new molecules and methods of their delivery have made management of these disorders free of complications. New discoveries of genetic abnormalities have helped in better classification of these disorders along with improved prognostication. Improved imaging techniques that help in better localization of target for deep brain stimulation, refinement of stereotactic procedure, and development of safer anesthetic procedure have together encouraged more patients opting for deep brain stimulation for treatment. In the near future, it is expected that more genetic varieties of disorders will be known which may help in genetic intervention for therapy.
