Full study name & original research details

Official study title

Sensing in Sleep and Deep Brain Stimulation

Short title used by the registry

Sensing in Sleep Deep Brain Stimulation

Original description

Participants in this study have Parkinson's Disease and already have a device, called the Percept RC Deep Brain Stimulation device implanted. People with Parkinson's disease often have issues related to sleep such as bad quality of sleep, waking up often and sleep apnea (breathing stops and starts during sleep). For this study, participants will be sleeping overnight in the study sleep lab for two nights. One night, Deep Brain Stimulation (DBS) device turned on and one night with the DBS off, either in this order or the reverse.

Further description from the registry

This prospective study will use the Percept sensing tools, collectively referred to as Brainsense, to correlate STN and GPi-LFP activity to sleep stages, characterize sleep events and evaluate the effects of DBS stimulation on sleep quality and sleep events. This study may help identify and validate novel biomarkers to assess sleep quality, REM behavior disorder,sleep fragmentation, and awakenings in patients with Parkinson's Disease, which will support overall DBS' efficacy beyond motor symptoms, and supplement interventions to improve sleep, and potentially also guide more effective DBS programming.

Conditions reported: Parkinson's Disease and Parkinsonism; Dyssomnia
