deep brain stimulation
Pronunciation: deep brayn stim-yoo-LAY-shun
Also written as: DBS — deep brain stimulation
Neurosurgical therapy involving implanted electrodes that deliver electrical pulses to specific brain targets.
Full Definition
Deep brain stimulation (DBS) is a neurosurgical treatment that involves the implantation of electrodes into specific deep brain structures, connected to a programmable pulse generator (similar to a cardiac pacemaker) placed subcutaneously. The system delivers controlled electrical stimulation to modulate abnormal neural activity. DBS is primarily used for movement disorders such as Parkinson's disease, essential tremor, and dystonia, with emerging applications in psychiatric conditions. The procedure requires precise stereotactic targeting and careful patient selection.
Usage
Usage note: Specify the target location (subthalamic nucleus, globus pallidus, etc.) in clinical documentation.
