Deep brain stimulation (DBS) is a surgical treatment that uses implanted electrodes and a pulse generator to deliver controlled electrical stimulation to specific areas of the brain. It is most commonly used for Parkinson’s disease, essential tremor, and dystonia.
DBS does not cure these conditions but can significantly reduce symptoms such as tremor, rigidity, slowness of movement, and involuntary movements. For many patients, DBS allows reduction of medication dosages and provides more consistent symptom control throughout the day.
How the Procedure Works
The procedure typically occurs in two stages. First, thin electrodes are precisely implanted into the targeted brain area using stereotactic guidance. In the second stage, a pulse generator is implanted under the skin near the collarbone and connected to the brain electrodes through extension wires.
- Stereotactic electrode placement guided by MRI
- Targeted stimulation of specific brain circuits
- Implantable pulse generator with adjustable settings
- Programming sessions to optimize therapeutic benefit
What Recovery Looks Like
Hospital stays are typically one to two days for each stage. Initial programming begins two to four weeks after the pulse generator is implanted. Multiple programming sessions over the following months fine tune the stimulation parameters. Medications are gradually adjusted in coordination with stimulation settings.
