Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is an effective treatment for the motor symptoms of advanced Parkinson's disease (PD). The aim of this study was to assess the effect of the bilateral surgical procedure and STN DBS on the neuropsychological functions. Twenty Parkinson's disease patients underwent a neuropsychological assessment before and 6 months after surgery in four different conditions: medication on (with levodopa) and medication off (without levodopa) during the preoperative period, medication on/stimulation on (levodopa plus stimulators switched on) and medication off/stimulation on (stimulators switched on without levodopa) during the postoperative period. We did not find any significant difference in the four conditions for all the neuropsychological tests, confirming the lack of an overall cognitive decline after surgery. From a neuropsychological point of view, these results seem to indicate that bilateral STN DBS is a safe treatment for advanced PD. (C) 2001 Elsevier Science B.V. All rights reserved.

Abstract

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is an effective treatment for the motor symptoms of advanced Parkinson's disease (PD). The aim of this study was to assess the effect of the bilateral surgical procedure and STN DBS on the neuropsychological functions. Twenty Parkinson's disease patients underwent a neuropsychological assessment before and 6 months after surgery in four different conditions: medication on (with levodopa) and medication off (without levodopa) during the preoperative period, medication on/stimulation on (levodopa plus stimulators switched on) and medication off/stimulation on (stimulators switched on without levodopa) during the postoperative period. We did not find any significant difference in the four conditions for all the neuropsychological tests, confirming the lack of an overall cognitive decline after surgery. From a neuropsychological point of view, these results seem to indicate that bilateral STN DBS is a safe treatment for advanced PD. (C) 2001 Elsevier Science B.V. All rights reserved.
