Deep Brain Stimulation
Also written as: DBS — Deep Brain Stimulation
Surgical procedure involving implanted electrodes that deliver electrical impulses to specific brain regions.
Full Definition
Deep Brain Stimulation (DBS) is a neurosurgical procedure that involves the implantation of a medical device called a neurostimulator, which sends electrical impulses through implanted electrodes to specific targets in the brain. This therapy is used to treat various neurological and psychiatric conditions including Parkinson's disease, essential tremor, dystonia, and treatment-resistant depression. The procedure requires precise targeting of brain structures and careful programming of stimulation parameters.
Usage
