Movement disorders are the third common neurological diseases after stroke and epilepsy. The prevalence of Parkinson's disease (PD), the commonest movement disorder, is 8-10/10000. Initially, for few years (5-10), PD can be managed with medical treatment. Thereafter, patients run into complications of medical treatment necessitating surgical intervention.

We started movement disorders surgery in 1997. We initially performed pallidotomies and thalamotomies for PD. However, in 1999, four years after the first published report of bilateral subthalamic nucleus (STN) stimulation for advanced PD by Prof. Benabid, we felt the need for introducing STN stimulation in our surgical armamentarium. I traveled to France and Austria to learn the finer aspects of these surgeries and performed the first STN stimulation as an Indian neurosurgeon in October 1999. Since then we have performed around 165 movement disorders surgeries including 104 cases of deep brain stimulation (DBS). The number of DBS surgeries, one of the most complex of all neurosurgeries, is not only highest in India but also in south East Asia . The other movement disorders for which we have performed surgeries include, dystonia, tardive dyskinesias, essential tremors, post stroke tremors, multiple sclerosis tremors, dystonic tremors etc. These surgeries have been performed in strict confirmation to international standards and protocol. The necessary clinical expertise infrastructure and results have been comparable to the best centres in the world.

The Functional neurosurgical program of Jaslok Hospital also offers surgical treatment for intractable epilepsy, spasticity, psychiatric disorders and chronic pain
