STN (Subthalamic)
Medication Reduction Lead
Impact Profile
Superior for medication reduction (up to 50%). Improves tremor, rigidity, and bradykinesia.
Nuances & Risks
Higher risk of mood/cognitive fluctuation and dysarthria.
GPi (Globus Pallidus)

Impact Profile
Unbeatable for L-dopa induced dyskinesia control. More stable cognitive profile.
Nuances & Risks
Lower potential for dramatic PD medication reduction.
Vim (Thalamus)
Isolated Tremor Lead
