Abstract
Objective
Deep brain stimulation (DBS) targeting the subthalamic nucleus (STN) is a common treatment for motor symptoms of Parkinson’s disease but its influence on non-motor symptoms is less clear. Sleep spindles are known to be reduced in patients with Parkinson’s disease, but the effect of STN DBS is unknown. The objective of our study was to address this knowledge gap.
Method
Polysomnograms were recorded for three consecutive nights in 15 patients with advanced Parkinson’s disease (11 male, 4 female; age: 53–75 years), including at least one night each of unilateral STN DBS stimulation ON and OFF. Stimulation ON was set to 70 % of clinical amplitude to mitigate sleep being altered via changing motor symptoms or due to patient awareness of stimulation. Sleep spindles were detected in electroencephalogram (EEG) data by two previously published, validated automated sleep spindle detection algorithms: Ferrarelli et al. (2007) and Martin et al. (2013).
Results
Sleep spindle density was higher during stimulation ON than OFF nights in 11 of 12 subjects using either sleep spindle detection algorithm (p<=0.01, Wilcoxon rank sum). Stimulation ON versus OFF had no statistically significant effect on sleep spindle duration or amplitude.
Conclusion
Our analysis indicates that a single night of sub-optimal STN stimulation significantly increases sleep spindle density in Parkinson’s disease patients.
Significance
These results further our understanding of how DBS impacts non-motor symptoms of Parkinson’s disease.
期刊介绍：
As of January 1999, The journal Electroencephalography and Clinical Neurophysiology, and its two sections Electromyography and Motor Control and Evoked Potentials have amalgamated to become this journal - Clinical Neurophysiology.
Clinical Neurophysiology is the official journal of the International Federation of Clinical Neurophysiology, the Brazilian Society of Clinical Neurophysiology, the Czech Society of Clinical Neurophysiology, the Italian Clinical Neurophysiology Society and the International Society of Intraoperative Neurophysiology.The journal is dedicated to fostering research and disseminating information on all aspects of both normal and abnormal functioning of the nervous system. The key aim of the publication is to disseminate scholarly reports on the pathophysiology underlying diseases of the central and peripheral nervous system of human patients. Clinical trials that use neurophysiological measures to document change are encouraged, as are manuscripts reporting data on integrated neuroimaging of central nervous function including, but not limited to, functional MRI, MEG, EEG, PET and other neuroimaging modalities.
