OBJECTIVE: This study reports a retrospective analysis of 67 consecutive parkinsonian patients to assess changes in antiparkinsonian medications after Deep Brain Stimulation (DBS) of the Subthalamic Nucleus (STN). METHODS: All antiparkinsonian drugs, including levodopa, dopamine agonists, associated drugs such as COMT and MAO inhibitors, amantadine and anticholinergics, were evaluated pre- and post-operatively at 1 and 3 years follow-up. RESULTS: The levodopa mean daily dose was reduced approximately 60% after 1 year and remained stable after 3 years. Apomorphine, bromocriptine, tolcapone, entacapone and selegiline were withdrawn after STN DBS. Three years post-operatively, 9 patients (13.4%) no longer required levodopa and 6 patients (8.9%) completely stopped all dopaminergic medications. More patients were on monotherapy of either levodopa or dopamine agonist and fewer patients required a combined treatment of dopamine agonist and levodopa, compared to the pre-surgical condition. CONCLUSIONS: STN DBS treated PD patients experience a significant long-term reduction and simplification of the pharmacological treatment.

Abstract

OBJECTIVE: This study reports a retrospective analysis of 67 consecutive parkinsonian patients to assess changes in antiparkinsonian medications after Deep Brain Stimulation (DBS) of the Subthalamic Nucleus (STN). METHODS: All antiparkinsonian drugs, including levodopa, dopamine agonists, associated drugs such as COMT and MAO inhibitors, amantadine and anticholinergics, were evaluated pre- and post-operatively at 1 and 3 years follow-up. RESULTS: The levodopa mean daily dose was reduced approximately 60% after 1 year and remained stable after 3 years. Apomorphine, bromocriptine, tolcapone, entacapone and selegiline were withdrawn after STN DBS. Three years post-operatively, 9 patients (13.4%) no longer required levodopa and 6 patients (8.9%) completely stopped all dopaminergic medications. More patients were on monotherapy of either levodopa or dopamine agonist and fewer patients required a combined treatment of dopamine agonist and levodopa, compared to the pre-surgical condition. CONCLUSIONS: STN DBS treated PD patients experience a significant long-term reduction and simplification of the pharmacological treatment.
