Sensing in Sleep Deep Brain Stimulation

3. juni 2026 opdateret af: Eleni Vaou, The University of Texas Health Science Center at San Antonio

Sensing in Sleep and Deep Brain Stimulation

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.

Detaljeret beskrivelse

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.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: STN-DBS Group
Participants diagnosed with Parkinson's Disease who have subthalamic nucleus (STN) deep brain stimulation as a primary target for their condition
Enhed: Polysomnography ON stimulation then OFF
Patients will undergo a 2-night Polysomnography (PSG). Stimulation will be set to "ON" stimulation for the 1st PSG night, then will cross over the 2nd PSG study night in the opposite stimulation state. Each subject will act as their own control.

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Sensing & Sleep: Parkinson's Disease Sleep Assessment
Tidsramme: Day 1 to Day 14
A 7 item to rate sleep experience scored 0=unsure, 1=No and 2=Yes. Total range of scores is from 0-14 with a higher score indicating more issues with sleep
Day 1 to Day 14
Motor severity
Tidsramme: Baseline to Day 14
Motor severity will be assessed by the Movement Disorders Society - Unified Parkinson's Disease Rating Scale - part III. This scale is the gold standard for measuring the severity and progression of PD. Part III entails motor examination which consists of 18 questions that are scored on a 0-4 scale. Higher scores suggest greater severity and progressing disease.
Baseline to Day 14
Epworth Sleepiness Scale (ESS)
Tidsramme: Baseline to Day 14
The ESS is a short, self-administered survey that asks respondents to rate their likelihood of dozing off in eight different situations on a scale of 0-3. The total score ranges from 0-24, and is used to estimate if the respondent has excessive daytime sleepiness that may require medical attention. A score over 10 is abnormal. Higher scores suggest greater severity of daytime sleepiness.
Baseline to Day 14
