It is a specialized neurosurgical treatment used to manage certain neurological conditions such as Parkinson’s disease, essential tremor, dystonia, and some cases of epilepsy. It involves implanting a small device, similar to a pacemaker, that sends controlled electrical impulses to specific areas of the brain responsible for movement and coordination. These signals help regulate abnormal brain activity and improve symptoms.

Before the procedure, detailed brain imaging such as MRI or CT scans are used to precisely identify the target brain regions. During surgery, thin electrodes are placed deep within the brain, and a pulse generator is implanted under the skin in the chest or abdomen. The device is then programmed and adjusted externally to achieve the best therapeutic effect.

For movement disorders like Parkinson’s disease, DBS can significantly reduce tremors, stiffness, and slowed movements, especially when medications become less effective. It does not cure the condition but helps improve quality of life and daily functioning. Based on the patient’s symptoms, diagnosis, and response to medications, a neurologist evaluates whether DBS is suitable and tailors the stimulation settings for optimal long-term results.
