Deep brain stimulation (DBS) devices are implantable neurostimulators used to treat a variety of neurological disorders, including Parkinson's disease, essential tremor, dystonia, and obsessive-compulsive disorder. These devices consist of electrodes that are surgically implanted into specific areas of the brain and connected to a pulse generator placed under the skin in the chest or abdomen. The electrodes deliver electrical impulses to modulate abnormal brain activity and alleviate symptoms associated with these conditions. DBS devices have been shown to significantly improve motor function, reduce tremors and dyskinesias, and enhance quality of life for patients who have not responded well to medication alone. While DBS therapy is generally safe and effective, it does carry some risks, such as infection, bleeding, or hardware malfunction. Therefore, careful patient selection and ongoing monitoring by healthcare professionals are essential for successful outcomes with DBS treatment.
