Naturalistic Sleep Assessed by Wearable Devices in Parkinson Disease
What this study is about
The cardinal motor features of Parkinson's disease (PD) include bradykinesia, rest tremor, and rigidity. Though non-motor features have been recognized for centuries, only recently has the prevalence and impact of non-motor symptoms become the focus of intense study.
View original scientific description
The cardinal motor features of Parkinson's disease (PD) include bradykinesia, rest tremor, and rigidity. Though non-motor features have been recognized for centuries, only recently has the prevalence and impact of non-motor symptoms become the focus of intense study. Disturbances of sleep are among the most common non-motor manifestations of PD; approximately two-thirds of PD patients experience sleep dysfunction of some kind. Given that sleep contributes to the regulation of many physiological processes, sleep disturbance has a significant impact on quality of life in PD, and places high strain on caregivers. Though numerous symptomatic therapies exist, the treatment of sleep disorders in PD is limited by a lack of adequately powered, randomized studies providing high quality evidence. Although deep brain stimulation (DBS) is primarily used to treat PD motor symptoms and reduce the need for dopaminergic medications, several studies have shown that DBS provides benefit for non-motor symptoms, including sleep disturbance. Few studies have used an objective measure to assess the impact of DBS on sleep in PD, and none have done so by studying sleep in the home environment. Existing studies have largely been limited to a single night of sleep recording in a sleep lab. Furthermore, no studies have assessed sleep both on and off medication, before and after DBS implantation. This study will enroll patients undergoing evaluation for DBS implantation. Sleep will be assessed before DBS implantation, both while patients continue their usual medication regimen and while withholding medications. After DBS implantation and programming, sleep will again be assessed with stimulation on, both while continuing medications and subsequently while withholding medications.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Research subjects must be willing and able to do the following:
- Be able to learn to use and maintain a wristband-style sleep monitor
- Wear a wristband-style sleep monitor for two weeks
- Be able to learn to use and maintain a headband sleep monitor
- Wear a headband sleep monitor for two weeks
- Log daily routine events, such sleeping, eating, and medication regimens for the two-week study period
- Withhold dopaminergic medications after 5:00pm for three consecutive nights
Exclusion criteria
- Subjects will be excluded if they:
- Carry a diagnosis of dementia (e.g., Parkinson's Disease Dementia or Dementia with Lewy Bodies)
- Currently use or recently (within past 30 days) used a sedative-hypnotic agent for sleep (e.g., Zolpidem, Suvorexant, Eszopiclone)
- Fulfill criteria or carry a diagnosis of a circadian sleep-wake rhythm disorder, as defined by the International Classification of Sleep Disorders, Third Edition
Where
- Aurora, Colorado
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
