Deep brain stimulation (DBS) is a medical procedure that involves implanting a device that sends electrical impulses to specific areas of the brain. This technique is primarily used to treat neurological disorders such as Parkinson's disease, essential tremor, and dystonia. The stimulation can help alleviate symptoms like tremors, rigidity, and movement difficulties. The DBS system consists of a pulse generator, electrodes, and a wire connecting them. Surgeons place the electrodes in targeted brain regions, while the pulse generator is usually implanted under the skin in the chest. Adjustments to the stimulation settings can be made to optimize treatment for each patient.
