Active clinical trials for "Sleep Wake Disorders"

Background: People who have had a traumatic brain injury (TBI) often experience fatigue. Fatigue is the feeling tired all the time. Researchers want to learn more about how TBI and fatigue are related. Objective: To better understand fatigue after TBI in active duty military and veterans. Eligibility: Active duty service members or veterans ages 25-40 who have sustained at least 1 TBI more than 6 months but less than 5 years ago Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Participants will have Visit 1 the same day as screening. This will include questionnaires and interviews. These will be about their fatigue, quality of life, and health. Participants will wear an activity monitor on their wrist and complete a sleep diary for 7 days at home. Participants will have Visit 2: They will stay in the clinic for 2 nights. The visit will include: Tests of memory, attention, and thinking Placement of intravenous (IV) line: A needle will guide a thin plastic tube into the participant s arm vein. 2 overnight sleeps tests: Participants brain waves will be recorded while they sleep. Small electrodes will be placed on the scalp. Monitors will be placed on the skin. These will measure breathing, heart rate, and movement. Blood will be drawn overnight through the IV line. Optional hydrocortisone stimulation test: Participants will receive the hormone through the IV line. Blood will be drawn through the IV line 5 times over 1 hour. Optional MRI: Participants will lie in a machine. This machine is a metal cylinder that takes pictures of the brain.

Non Rapid Eye Movement (NREM) sleep parasomnias (sleepwalking and sleep terrors) are frequent and disabling sleep disorders characterized by arousal specifically from slow wave sleep (SWS) with dissociated brain activity that may be related to lower nociceptive state. The investigators recently reported frequent subjective complaints of chronic pain, migraine and headache during wakefulness in adult sleepwalkers. They also described frequent analgesia during severe and injuring episodes, suggesting a relationship between dissociated brain activity and nociceptive dysregulation. However, this study did not included objective nociceptive measures and the retrospective assessment of perceived pain during parasomnia episodes over a lifetime span might also introduce a recall bias. The aims of the present study are to measure objective pain sensitivity in patients with NREM parasomnias and matched controls during 1) parasomniac episodes, 2) light NREM sleep and SWS, and 3) wakefulness. Fifteen adults with severe NREM parasomnia and 15 age and sex-matched controls will be recruited. A 25 hours (8 AM to 9 AM) sleep deprivation protocol followed by auditory stimulations during SWS will be used to trigger parasomniac episodes. Thermoalgic stimulations of graduate intensity will be applied during wakefulness (8 PM) to determine the nociceptive threshold. During the recovery sleep following the sleep deprivation, the investigators will apply repeated subthreshold thermoalgic stimulations in NREM stage 2, SWS and triggered parasomniac episodes and report the behavioural/neurophysiologic nociceptive responses. The investigators hypothesized a lower nociceptive threshold during wakefulness in sleepwalkers and a decrease of the arousabiliy during SWS and parasomniac episodes. This study may help to better understand the etiology and mechanisms underlying the clinical enigma of the nociceptive dysregulation in NREM sleep parasomnias.

RATIONALE: Measuring levels of interleukin-6 and depression may help doctors understand the relationship between interleukin-6 and depression. It may also help the study of cancer in the future. PURPOSE: This clinical trial is studying depression and interleukin-6 production in patients with ovarian epithelial cancer.

Sleep disorders and disturbances are mostly underestimated in clinical practice. Moreover, this problem is generally neglected by the pregnant themselves. Today, it is important to underline any problem that may have an affect to improve the quality of life during pregnancy. This study assesses the sleep quality, insomnia patterns and obstructive sleep apnea in the second and third trimesters of pregnancy.

This study is to investigate sleep disorders in patients with dermatologic diseases by taking into consideration dermatologic (itch, pain) and non- dermatologic (medication, depression) factors.

The objective of this study is to collect data comparing the Zensorium Biosensing Wearable Device (zBWD) to polysomnography (PSG) in individuals with Sleep-Wake Disorders. zBWD is similar to other wearable devices (e.g., fitbit and apple watch) that use an optical light sensor and Tri-axis Accelerometer to record steps, activity, sleep/awake states, sleep staging, and statistical variation of pulse pressure to track stress. Specifically, it is designed to report sleep duration, non-rapid eye movement (NREM) and REM sleep duration. However, zBWD has not been validated against PSG for sleep tracking in healthy controls or in individuals with sleep-wake disorders.

The aim of this study is to examine sleep architecture in refugees with PTSD. Polysomnography (PSG) will be carried out to study the occurrence of sleep disorders in patients and healthy controls.

Heart failure (HF) is a common and progressive condition associated with significant morbidity and mortality. Only 25-35% of patients survive 5 years after diagnosis.Sleep disorders are frequently found in this population with up to 94% of patients complaining of sleep disorders. Of these, insomnia and sleep disorders are the most common. The frequency of restless legs syndrome (RLS) varies between 4 and 40% depending on the studies. Patients with HF frequently experience poor sleep quality which is associated with deterioration in quality of life, alertness, and mood. Few studies have examined the prognostic impact of sleep disturbances in this population. A greater morbidity and mortality is observed in the event of poor quality sleep or in the presence of sleep breathing disorders . The investigators therefore propose to evaluate the sleep disorders of patients with HF by self-administered questionnaires, hypothesizing that complaints of poor sleep are linked to a poorer cardiovascular prognosis.

The aim of this study is to describe and compare the anaesthesia history and possible problems encountered in 3 groups of patients with 3 chronic sleep diseases: narcolepsy, idiopathic hypersomnia, and restless legs syndrome followed at the Montpellier Sleep Unit. For each participant, existing data from the medical record will be used, with their consent. All participants will complete a standardized questionnaire, concerning their history of anaesthesia, the course and possible complications, and questions about their treatment for their sleep disorder.

Lymphangioleiomyomatosis (LAM) is a rare and progressive pulmonary disease of unknown etiology that almost exclusively affects women. It is characterised by cystic radiological lung pattern and by the possible presence of angiomyolipomas in other sites or organs. Functionally LAM is associated with airway obstruction or restriction and progressive hypoxemia up to chronic respiratory failure. There are no studies, so far, which have investigated whether during sleep these patients show changes in the sleep profile and gas exchange and if these changes are related to disease severity. Aim of the study, prospective and pilot, is to evaluate whether the physiological modification of respiratory mechanics during sleep is associated with polysomnographic alterations in LAM.
