Deep Brain Stimulation

Deep Brain Stimulation

Deep brain stimulation (DBS) surgery is a type of neuro-modulation surgery for the treatment of Parkinson’s disease, essential tremor, dystonia, obsessive-compulsive disorder, and major depression.

Deep brain stimulation surgery is proven to be effective in advanced Parkinson’s disease, dystonia and essential tremor and its use in pscychiatric diseases such as obsessive-compulsive disorder and major depression is being evolved and there are promising publications in the literature.

How does deep brain stimulation work?

The rationale behind Deep brain stimulation surgery is to bypass the abnormal electrical circuits in the brain by applying low current- high frequency electrical impulses through tiny electrodes implanted in the deep seated nuclei of the brain which are responsibe for the synchronization of the fine movements in arms and legs.

DBS surgery is a type of brain surgery and tiny, slender electrodes are placed in the desired brain spot with a strict accuracy. Battery of DBS is generally switched on few days-1 week following surgery and DBS settings are arranged at the optimal level by specialized neurologist/neurosurgeon team.

The overall success rate of DBS surgery in experienced hands is around 85-95%.
