Medication comes first
For most people with Parkinson's, tablets control the symptoms well for several years. Surgery is never the first step — it is considered only when medication alone stops being enough.
Signs that surgery may help
- Your medicines wear off before the next dose ("off" periods).
- You get strong, uncontrolled movements (dyskinesia) from the medication itself.
- Tremor stays severe despite good medical treatment.
What the surgery does
The goal is to calm the specific brain circuits that drive the tremor and stiffness — giving smoother, more predictable control through the day. Each patient is assessed individually before any decision.
