NCT ID: NCT05094271 Recruiting - Alzheimer Disease Clinical Trials

Is Obstructive Sleep Apnea Important in the Development of Alzheimer's Disease?

Start date: June 30, 2021
Phase: Phase 1
Study type: Interventional

Obstructive sleep apnea (OSA) is common in older adults and has recently been implicated in pathogenesis of Alzheimer's disease (AD). Research has shown that sleep disruptions have caused memory impairment. Sleep apnea is a form of sleep disruption. We would like to examine how obstructive sleep apnea may contribute to the progression of Alzheimer's disease.

NCT ID: NCT04948541 Completed - Pain Clinical Trials

Effect Of Sleep Apnea Treatment On Temporo-Mandibular Disorders

Start date: April 21, 2021
Phase: N/A
Study type: Interventional

Aims of this research are to detect if an improvement in sleep pattern in patients suffering from obstructive sleep apnea (OSA), produces a reduction in pain and dysfunction in the orofacial area by examining variation in temporo-mandibular disorder (TMD) signs and symptoms and if the prevalence of TMDs in OSA patients controlling this disease decreases to levels comparable to healthy subjects. 41 OSA patients will undergo a complete TMD examination prior to start any OSA treatment and after at least 18 months of therapy. Variations in TMD signs and symptoms will be recorded.

NCT ID: NCT04937036 Enrolling by invitation - Clinical trials for Cardiovascular Diseases

Impact of Bruxism Related Arousals on Cardiovascular Risk in Co-morbid Insomnia and Sleep Apnea

Start date: June 1, 2021
Phase:
Study type: Observational

Sleep disordered breathing is a common and serious health problem. According to epidemiological data, it may affect about 20% of adult population. The majority is not aware of the disease. The most common sleep disorder is obstructive sleep apnea (OSA). The essence of OSA are the episodes of airway obstruction repeated many times during sleep, as a result of which the level of partial oxygen in the blood decreases. Apnea episodes end up waking from sleep, causing sleep fragmentation, deep sleep and REM deficiency. Frequent complications of OSA are hypertension, stroke, cardiac arrhythmia, coronary artery disease and pulmonary hypertension. Comorbid Insomnia and Sleep Apnea (COMISA) is a highly prevalent and debilitating disorder that causes additional disturbances in sleep, daytime functioning, and quality of life for patients, and is a significant diagnostic and therapeutic problem for clinicians. Although the presence of COMISA was first noticed by Christian Guilleminault and his colleagues in 1973, it received very little research attention for almost three decades. There is still lack ofclinical trials concerning this topic. An additional problem in apnea patients is the increased incidence of bruxism. Bruxism is associated with increased masticatory muscle activity during sleep, which may be phased or tonic. It is estimated that the incidence of bruxism in the adult population is 13%. The most common symptoms of bruxism include: pathological wear and tooth sensitivity, damage to the periodontium and oral mucosa, muscle pain in the stomatognathic system, headaches and damage to prosthetic restorations. However, the symptoms of bruxism can go unnoticed for a long time, leaving patients often unaware of the problem. The aim of this project is: 1. to determine the prevalence of sleep bruxism in COMISA, OSA and insomnia, 2. to examine of arousals (type, frequency) in COMISA, OSA and insomnia, 3. to investigate the relationship between arousals and blood pressure values and variability, arrhythmias, sinus rhythm variability, vascular endothelial dysfunction, cardiovascular risk in COMISA, OSA and insomnia.

NCT ID: NCT04928157 Recruiting - Pain Clinical Trials

Prospective Randomized Trial of CPAP for SDB in Patients Who Use Opioids

PRESTO
Start date: August 10, 2021
Phase: Phase 2
Study type: Interventional

Patients with chronic pain who use opioids appear to be at increased risk for breathing issues during sleep, termed sleep disordered breathing (SDB). Treatment of SDB often consists of use of a device during sleep that provides continuous positive airway pressure (CPAP) via a mask interface. The goal of this study is to determine whether patients with chronic pain who use opioids and have SDB might benefit from the use of CPAP in terms of sleep quality, pain, quality of life, and other measures. In addition, the study will examine whether these individuals are able to adhere to CPAP, which will be important for future studies. Lastly, we anticipate that CPAP won't work for everyone due to the changes that opioids can cause in breathing patterns. We will examine how often CPAP is ineffective, and whether we can predict which individuals are least likely to resolve their SDB with CPAP.

NCT ID: NCT04903951 Not yet recruiting - Stroke Clinical Trials

Impact of Early Ventilation in Stroke Outcomes in Patients With Sleep Apnea After First Ever Stroke

Start date: November 2022
Phase: Phase 2
Study type: Interventional

To evaluate the impact of early ventilation in stroke outcomes in patients with sleep apnea and first ever stroke, 1 month after stroke.

NCT ID: NCT04882020 Active, not recruiting - Inflammation Clinical Trials

Inflammation and Neurocognitive Damage Markers in Elderly People With Obstructive Sleep Apnea

Start date: August 21, 2019
Phase:
Study type: Observational

The aging process tends to promote an overall increase in inflammation compromising the immunologic system regulation, sleep/wakefulness pattern, and neurocognitive performance. In elders, there is an increase in repetitive arousals during sleep, secondary to breathing interruption by pharynx collapse, generating a transient reduction in oxygen delivery to the brain known as obstructive sleep apnea. This lack in oxygen supply results in an inflammatory process producing brain damage. Some substances present in the blood seem to be associated to neurocognitive damage, like S100β protein, cortisol, interleukin 1-β,6 and TNF-α. In the other way, a substance called brain-derived neurotrophic factor (BDNF) enhances cognitive function, and memory consolidation improvement.

NCT ID: NCT04875364 Recruiting - Clinical trials for Obstructive Sleep Apnea

Do Endotypes Predict Response and Sequelae in OSA Patients

ExPRESSION
Start date: August 1, 2020
Phase: Phase 2
Study type: Interventional

This study will investigate why some people have Obstructive Sleep Apnea (OSA) and how the underlying cause may relate to OSA manifestations (including sleepiness and high blood pressure) and response to different therapeutic approaches (ie CPAP, eszopiclone, and supplemental oxygen). Understanding why someone has OSA could affect how best to treat that individual, but may also have an impact on what problems the disease might cause.

NCT ID: NCT04874727 Completed - Sleep Apnea Clinical Trials

Comparison of Standing Versus Supine 3D Cone Beam Computed Tomography in Patient With Obstructive Sleep Apnea

OSA
Start date: July 1, 2019
Phase:
Study type: Observational

The anatomical changes of the upper airway in a standing vs pseudo-supine position using Carestream Orthodontic Imaging (Volumetric) and Carestream Orthodontic Imaging module (AP measurements) of the patient's airway respectively, have been taken and the obtained results compared. In order to simulate the supine position, patients are placed in a supine position (180 degrees) in a dental exam chair, and asked to relax their lower jaw, allowing it to drop back, simulating their jaw falling back while sleeping. That bite is then captured with a Correct Plus™ Impression Material Superfast. Once the bite material hardens, it locks the bite in place. The patient then stands upright, and CBCT is taken standing while the jaw placement is still pseudo sleep-supine, supported by the bite material.

NCT ID: NCT04868682 Recruiting - Sleep Apnea Clinical Trials

Addressing Insufficient PAP Use in Older Veterans

Start date: January 10, 2022
Phase: N/A
Study type: Interventional

Sleep apnea is a common problem in middle-aged and older Veterans that is associated with poor nighttime sleep, more daytime sleepiness, poor functioning and worse quality of life. The recommended therapy for most patients with sleep apnea is positive airway pressure (PAP) therapy; however, over time many patients prescribed PAP therapy no longer use it regularly. This study will test the effects of an education program specifically designed for middle-aged and older Veterans who have stopped using their PAP device, or are not using it regularly. Eligible Veterans who are enrolled into the study will receive a baseline assessment that includes questionnaires about sleep, health, and quality of life. After completing the baseline assessment, participants will be randomly assigned to one of two education groups. Both groups will meet individually with a "sleep coach" for 5 session over 8 weeks, then they will be contacted monthly by telephone for up to 6 months. Participants will complete follow-up assessments immediately after the fifth education session and again at 6-months and 12-months. If successful, this approach has the potential to improve sleep, function and quality of life in middle-aged and older Veterans.

NCT ID: NCT04816136 Completed - Ischemic Stroke Clinical Trials

Consequences of Post Stroke Polysomnographic Abnormalities on Functionnal Recovery and Survival After an Ischemic Stroke

PSG-AVC
Start date: January 1, 2002
Phase:
Study type: Observational

Ischemic stroke is a major public health issue, likely to cause functional disability. It is well known that sleep has an impact on brain plasticity, and after an ischemic stroke, studies have shown subjective sleep quality alterations and sleep architecture abnormalities. Furthermore, there is no clear guideline showing the usefulness of a systematic sleep investigation following an ischemic stroke. The aim of the study is to identify retrospectively correlation between polysomnographic abnormalities (sleep apnea, periodic limb movements, disturbed sleep architecture…) and functional recovery after an ischemic stroke. The study also assesses the impact of sleep abnormalities on survival, and the risk of new cardiovascular event.
