Multicenter Study Observational StudyBeneficial effect of 24-month bilateral subthalamic stimulation on quality of sleep in Parkinson's disease.
Subthalamic nucleus (STN) deep brain stimulation (DBS) improves quality of life (QoL), motor, and sleep symptoms in Parkinson's disease (PD). However, the long-term effects of STN-DBS on sleep and its relationship with QoL outcome are unclear. ⋯ In this multicenter study with a 24 months follow-up, we report significant sustained improvements after bilateral STN-DBS using a PD-specific sleep scale and a significant relationship between sleep and QoL improvements. This highlights the importance of sleep in holistic assessments of DBS outcomes.
