What is Bilateral DBS?

Deep brain stimulation places electrodes in specific brain targets (subthalamic nucleus or globus pallidus interna for Parkinson's) connected to a pacemaker-like device. Continuous high-frequency stimulation modulates abnormal circuit activity, dramatically reducing tremor, rigidity, and bradykinesia.

Why China?

• Pinnacle expertise: Tiantan, Xuanwu, and Huashan perform 200-400 DBS/year each
• Cost: $30,000-$50,000 vs. $80,000-$150,000 in the US
• Domestic IPG: NMPA-approved PINS Medical and SceneRay systems at 1/3 Medtronic cost
• Directional leads: Latest 8-contact directional leads for precision steering

Who is a candidate?

• Idiopathic Parkinson's disease ≥4 years duration
• Motor fluctuations or dyskinesia despite optimal medication
• Robust L-DOPA response (≥30% UPDRS improvement)
• Essential tremor refractory to medication (Vim target)
• Dystonia (GPi target)

Outcomes

Off-medication UPDRS-III improvement: 50-60%. Levodopa equivalent dose reduction: 50%. Dyskinesia reduction: 60-70%. Battery life: 3-5 years (rechargeable models 15+ years).
