Treatment of Parkinson's Disease Tremor
Tremor is a prominent and often disabling feature of Parkinson's disease. In some patients, tremor remains difficult to control even after optimising standard oral pharmacotherapy, raising the question of when and how to escalate management.
Clinical Scenario
This protocol addresses Parkinson's disease where tremor is the defining management challenge. When standard oral therapy at established doses is insufficient to achieve adequate tremor control, a structured, evidence-based approach guides further decision-making.
Treatment Approach (overview)
When optimising oral medication based on akinesia and rigidity targets has not controlled tremor, the approach shifts toward specialised interventional strategies — including brain stimulation techniques — as the next considered option. The full protocol specifies which interventions apply, in what order, and under what conditions.

- For PD tremor refractory to standard Levodopa doses, increasing Levodopa daily dosage or high Levodopa single doses can be helpful in individual cases.
- When optimizing oral medication based on target symptoms of akinesia and rigidity failed to control tremor, special interventions such as deep brain stimulation (DBS) or pump therapies can be considered.
- STN DBS should also be offered to Parkinson's patients with severe, medication-resistant tremor, preferably performed bilaterally.
- Uni- or bilateral VIM DBS and GPi DBS are effective for treating medication-resistant PD tremor, especially when STN DBS is contraindicated.
- Anticholinergics may only be considered in exceptional cases for PD patients with otherwise untreatable tremor due to their anticholinergic side effects.
