DBS
Pronunciation: D-B-S
Also written as: DBS — Deep Brain Stimulation
Deep brain stimulation; a neurosurgical treatment using implanted electrodes to modulate brain activity.
Full Definition
Deep brain stimulation (DBS) involves the surgical implantation of electrodes into specific brain regions to deliver controlled electrical impulses for treating neurological and psychiatric conditions. Common targets include the subthalamic nucleus for Parkinson's disease, the globus pallidus for dystonia, and the anterior limb of the internal capsule for obsessive-compulsive disorder. DBS systems consist of implanted leads, an extension wire, and a programmable pulse generator. In neurocritical care, DBS patients require special consideration for imaging protocols, medication interactions, and perioperative management. Clinical documentation must specify target location, stimulation parameters, and device-related precautions.
Usage
Usage note: Specify anatomical target and indication. Note device status for imaging and procedures.
