INTRODUCTION: Clinical outcomes of Parkinson's disease patients treated for 12 months with STN-DBS were analyzed. PATIENTS ADN METHODS: Twelve patients were selected using the CAPSIT protocol criteria and placement of electrodes in the appropriate target was performed according to results of fusion image techniques and intraoperative microrecording. RESULTS: A reduction in motor UPDRS (44 %) and activities of daily living (58 %) scores during <<off>> phases were observed. <<On>> time with dyskinesias was reduced (86 %), while severe dyskinesias disappeared. Levodopa dosage was also lowered (44 %). Patients and caregivers showed a clear-cut benefit on quality of life (58 % and 61 % respectively). No cognitive deterioration was observed and morbidity was in the same range as that published by other teams. CONCLUSION: Bilateral STN-DBS is an effective symptomatic therapy for complicated Parkinsońs disease patients. It improves the quality of life of patients and their caregivers and allows a reduction of levodopa dosage.
