5. Study Description
Brief Summary
Sleep disturbances are one of the most common non-motor symptoms in PD, with an estimated prevalence as high as 40-90%. Sleep disturbances (particularly sleep duration, sleep fragmentation, Rapid Eye Movement (REM) sleep behavior disorder and sleep-disordered breathing) have been associated with an increased risk of neurodegeneration and are an independent risk for cognitive decline and dementia in PD.
Although much is currently unknown about sleep changes in PD, sleep-related symptoms are increasingly recognized as a major contributor to disease burden and reduced quality of life among people with PD. The "gold standard" evaluation of nocturnal sleep is polysomnographic monitoring (PSG).
This study proposes to use novel wireless skin electrodes and wearable sensors to provide a "home PSG test" incorporating several physiologic recordings, over multiple nights in the person's home, enabling the objective evaluation of night-to-night fluctuations.
Detailed Description
Background Sleep disturbances are one of the most common non-motor symptoms in PD, with an estimated prevalence as high as 40-90%. Sleep disturbances (particularly sleep duration, sleep fragmentation, Rapid Eye Movement (REM) sleep behaviour disorder and sleep-disordered breathing) have been associated with an increased risk of neurodegeneration and are an independent risk for cognitive decline and dementia in PD. The etiology of impaired sleep and alertness in PD is multifactorial and may be due to the interactions between internal and external factors such as primary sleep disorders, primary neurodegeneration, medication side effects, environmental conditions and genetic factors (either associated with sleep or associated with disease phenotype). Each can contribute to sleep disturbances alone or as modifiers, resulting in variability of presentation and symptoms, affecting both the diagnosis, and the treatment of these disorders. Although much is currently unknown about sleep changes in PD, sleep-related symptoms are increasingly recognized as a major contributor to disease burden and reduced quality of life among people with PD.
The "gold standard" evaluation of nocturnal sleep is polysomnographic monitoring (PSG). PSG consists of measuring neural function, eye movements, muscle activity, respiratory status and electrocardiography activity while the person sleeps over-night in a laboratory setting. This assessment allows for quantification of the different sleep stages during non-REM and REM, evaluation of their distribution over the course of the night, and the identification of impairments in each of these stages. However, PSG is time, cost and labor-intensive, may not reflect the typical behavior of the person due to the unfamiliar environment and irregular sleeping conditions, and more importantly, only provides information on one night of sleep.
In recent years, there is heightened interest in home-based sleep monitoring via wearable sensors to address these shortcomings. Body-fixed electrophysiological sensors can objectively quantify sleep quality, generating a detailed map of the person's sleeping pattern and nocturnal movements. They are relatively inexpensive enabling wide-spread use.
This study proposes to use novel wireless skin electrodes and wearable sensors to provide a "home PSG test" incorporating several physiologic recordings, over multiple nights in the person's home, enabling the objective evaluation of night-to-night fluctuations. By applying these novel tools to the study of people with PD as well as controls and subjects at risk for developing PD, the results of this study will open the door for using a new method for assessment of prodromal signs and disease progression.
Study objective
Main objective is to use the combined wearable system described above to evaluate sleep disturbances across a wide spectrum of PD disease severity: from the prodromal phase with individuals at risk to mild and advanced PD:
To investigate changes in sleep architecture and unique patterns of sleep in individuals at risk for developing PD (patients with confirmed RBD and carriers of mutations in the LRRK2 and GBA genes) that can help to better identify increased risk of disease.
To assess the frequency, severity and types of sleep disturbances in patients with PD across the disease spectrum.
To identify classifiers of sleep measures indicative of disease characteristics, severity and progression.
To assess the association between sleep disorders, disease severity, autonomic, motor, cognitive functions, and medication.
Subjects will be recruited and evaluated from the Laboratory for Early Markers of Neurodegeneration (LEMON) at the Neurological Institute at the Tel Aviv Medical Centre (TLVMC). All subjects will provide informed written consent as approved by each TLVMC's ethical committee and in accordance with the Helsinki agreement prior to participation.The 'Genetics in Parkinson's Study' registry will be used for initial recruitment of participants. This is a registry of participants (patients and family members who have undergone genetic testing in our lab previously and have agreed to allow contact for future studies (under Helsinki agreement of 05-069 and 07-0381). PD patients will be approached by their physician to provide consent to participate in the sleep study. Asymptomatic participants will be recruited from the registry or from public advertisements and word to mouth approach. Those willing to participate will be invited to LEMON for an assessment meeting. Subjects will be provided with a detailed explanation of the study protocol before being asked to sign the consent form.
Procedures:
After signing an informed written consent, participants will be asked about their current and medical history, sleep habits, dietary, alcohol and caffeine consumption and any medication they are receiving. Subjects will then undergo a through neurological assessment and blood pressure supine and standing, pulse rates, weight, height will be obtained.
A blood sample (15 cc) will be drawn to test the association to metabolic, hormonal and inflammatory mediators known to affect sleep (specifically: iron stores, thyroid function, and hemoglobin). Subjects will also undergo several performance based assessments and questionnaires on sleep and behavior.
All subjects will then be scheduled for a sleep polysomnography (PSG). Subjects will be invited to the sleep lab at TLVMC and asked to arrive at 9 pm and will be instructed on all procedures. Several body functions will be recorded during the PSG including brain activity, eye movement, oxygen and carbon dioxide blood levels, heart rate and rhythm, breathing rate and rhythm, the flow of air through the mouth and nose, body muscle movements, and chest and belly movement. The standard PSG will be fitted first and then the Xtrode system will be placed on the subject's face and the Axivity sensor will be placed on the subjects back (L4-5) using medical tape. This process should take approximately 45 minutes. After the systems are turned on, the subjects will be left in the quite room for a night sleep. The session will be video-taped to enable a comparison of movement with the wearable systems. The PSG and Xtrodes systems will be removed no later than 8 am the next morning.
Subjects will then be instructed on how to use the sleep "tattoo" at home. The system provided will include the controller, seven skin adhesives and a smartphone app, which will be used to obtain the data collected. Data is automatically transferred from the skin tattoo directly to the smartphone via a Bluetooth connection. The Axivity device which was placed on the lower back of the subjects will remain in place for the remaining 7 days. The device is waterproof thus there is no need for the subjects to don or doff the device until the end of the collection period. After the study, the systems will be returned to the medical centers for data transfer and analysis via carrier.
