[Deep brain stimulation in movement disorders: a Prague-center experience]

Area of Science:

• Neurology
• Neurosurgery

Context:

• Deep brain stimulation (DBS) is a crucial therapy for movement disorders.
• Electrodes target key basal ganglia structures like the subthalamic nucleus (STN), internal globus pallidus (GPi), and ventral intermediate nucleus (VIM).

Purpose:

• To evaluate the efficacy and safety of DBS in treating Parkinson's disease (PD), essential tremor (ET), and dystonia.
• To report outcomes from a large patient cohort at the Center for Movement Disorders in Prague.

Summary:

• DBS was performed on 127 patients: 86 with PD, 19 with dystonia, and 22 with tremor.
• Intraoperative success rates included eliminating rigidity in 95% of PD cases and tremor in 93% of ET cases.
• Dystonia symptom improvement occurred in 95% of patients within weeks, with overall low complication rates (8% transient morbidity, 1% hemorrhage, 6% infection, 7% hardware issues).

Impact:

• DBS offers significant symptom relief for debilitating movement disorders.
• The study demonstrates the clinical effectiveness and manageable safety profile of DBS in a substantial patient group.
• Findings support DBS as a valuable treatment option for selected patients with PD, ET, and dystonia.
