1. The loss of central dopamine, which characterises Parkinson's disease, led to the main pharmacological strategy for treatment, namely levodopa, a dopamine-replacement therapy. Several years after treatment, the majority of patients experience dose-limiting side-effects and loss of symptom control. ⋯ Post-mortem analysis did not demonstrate substantial damage of the STN as a result of the electrodes. 4. Although unilateral subthalamotomy improves some aspects of parkinsonism, it causes postural abnormalities in animal models of Parkinson's disease. Because bilateral high-frequency STN stimulation improves disease symptoms, is reversible and is not reported to induce postural side-effects, it may be a better surgical therapy for Parkinson's disease than lesioning the STN.
