Research suggests that poor sleep quality is related to the occurrence of sleep paralysis, although the precise relationship between these two variables is unknown. This association has generated interest due to the related possibility that improving sleep quality could help to combat episodes of sleep paralysis. To date, studies examining the association between sleep quality and sleep paralysis have typically measured sleep quality using general measures such as the global score of the Pittsburgh Sleep Quality Index (PSQI)...

Many studies investigating sleep and memory consolidation have evaluated full-night sleep rather than alternative sleep periods such as daytime naps. This multi-centre study followed up on, and was compared with, an earlier full-night study (Schabus et al., 2004) investigating the relevance of daytime naps for the consolidation of declarative and procedural memory. Seventy-six participants were randomly assigned to a nap or wake group, and performed a declarative word-pair association or procedural mirror-tracing task...

Rapid eye movement sleep behavior disorder (RBD) is a brain disorder, characterized by the dream enactment during rapid eye movement (REM) sleep due to a lack of physiologic muscle atonia and increased muscle twitching. Schenk was the first to describe this disorder in 1986; however, few authors reported in the 1970-1980s loss of physiological muscle atonia combined with dream enactment in the course of brainstem disorders and as a consequence of alcoholism and antidepressant treatment. RBD affects less than 1% of the adult population, but can be found in up to 25-50% of neurodegenerative disorders including Parkinson's disease, multisystem atrophy, and dementia with Lewy body...

Due to its low rate of diagnosis, in the general population over half of those experiencing obstructive sleep apnea (OSA) are unaware that they have the condition. However, any acute medical event may exacerbate OSA and could have serious health consequences. In this context the management of the perioperative period, from anesthesia through the surgery itself and into the postoperative period, is more problematic for patients with sleep disordered breathing than for others. There is prolific literature in this area although large randomized trials are few due to the high sample size needed and possible ethical difficulties of withholding OSA treatment in the perioperative period...

Sleep disturbances are associated with future risk of Alzheimer's disease. Disrupted sleep increases soluble amyloid-β, suggesting a mechanism for sleep disturbances to increase Alzheimer's disease risk. We tested this response in humans using indwelling lumbar catheters to serially sample cerebrospinal fluid while participants were sleep-deprived, treated with sodium oxybate, or allowed to sleep normally. All participants were infused with 13 C6 -leucine to measure amyloid-β kinetics. We found that sleep deprivation increased overnight amyloid-β-38, amyloid-β-40, and amyloid-β-42 levels by 25-30% via increased overnight amyloid-β production relative to sleeping controls...

Obstructive sleep apnea (OSA) is associated with increased cardiovascular morbidity and mortality. This study systematically reviews the effects of oral appliance therapy (OAT) on a broad spectrum of cardiovascular outcomes. A literature search was performed up to December 31st 2016. Twenty-five relevant full-text articles were retrieved. Sixteen articles were considered methodologically sufficient, including 11 randomized controlled trials. Pooled data of the RCTs showed significant reductions in daytime systolic and diastolic blood pressure compared to baseline, but no significant reductions in heart rate, except for daytime heart rate when compared to inactive/placebo OAT...

Sleep deprivation is a major source of morbidity with widespread health effects, including increased risk of hypertension, diabetes, obesity, heart attack, and stroke. Moreover, sleep deprivation brings about vehicle accidents and medical errors and is therefore an urgent topic of investigation. During sleep deprivation, homeostatic and circadian processes interact to build up sleep pressure, which results in slow behavioral performance (cognitive lapses) typically attributed to attentional thalamic and frontoparietal circuits, but the underlying mechanisms remain unclear...

The prevalence and consequences of nasal obstruction in untreated obstructive sleep apnea patients are not known. The study objectives were to investigate the frequency of subjective and objective nasal obstruction in untreated sleep apnea patients and the associations with sleep and quality of life. Patients in the Icelandic Sleep Apnea Cohort were subjected to a type 3 sleep study, answered questionnaires and had their nasal dimensions measured by acoustic rhinometry. In total, 810 patients participated (including 153 females), aged 54...

Rapid eye movement sleep behavior disorder (RBD) is diagnosed by a clinical history of dream enactment accompanied by polysomnographic rapid eye movement sleep atonia loss (rapid eye movement sleep without atonia). Rapid eye movement sleep behavior disorder is strongly associated with neurodegenerative disease, especially synucleinopathies such as Parkinson disease, dementia with Lewy bodies, and multiple system atrophy. A history of RBD may begin several years to decades before onset of any clear daytime symptoms of motor, cognitive, or autonomic impairments, suggesting that RBD is the presenting manifestation of a neurodegenerative process...

The Chiari 1 malformation is characterized by > 5-mm herniation of the cerebellar tonsils through the foramen magnum. Consequent compression of the brain stem and nearby neuronal structures involved in respiratory control and maintenance of pharyngeal wall muscle tone may result in respiratory changes during sleep. These changes include respiratory failure and arrest, as well as sleep-related breathing disorders (ie, OSA and central sleep apnea). Although data have accrued on the significance of sleep-related breathing disorders in patients with the Chiari 1 malformation, many management questions remain unanswered...

Sleep disturbances and dementia are two common and significant health problems in older adults. Investigations suggest that sleep disturbances might increase the risk of dementia. The aim of the present study was to systematically review and meta-analyze the predictive roles of overall sleep disturbances, their subtypes (e.g., insomnia, sleep disordered breathing [SDB]), and other sleep problems (e.g., excessive daytime sleepiness, sleep-related movement disorder, circadian rhythm sleep disorder, and nonspecific sleep problems) in incident all-cause dementia and Alzheimer's disease (AD) and vascular dementia subtypes...

OBJECTIVE: Most studies have used cardiovascular and cerebrovascular disease (CVD) end-points to measure the effect of continuous positive airway pressure (CPAP), but pre-diagnostic morbidities involve a range of comorbidities that may influence the consequences of obstructive sleep apnea (OSA). We therefore aimed to evaluate all-cause total mortality after a diagnosis of OSA, the effect of CPAP in women and men, and the potential effect of major comorbidities. METHODS: We used national registry data as a historical cohort and included 22,135 OSA patients aged 20 years or more with comorbidity data three years before diagnosis and follow-up morbidity and mortality over a period of 17 years...

Increasing evidence proved that obstructive sleep apnea (OSA) is associated with a variety of diseases, especially cardiovascular diseases. This study systematically reviewed the existing publications to assess the influence of OSA on cardiovascular survival among patients who underwent percutaneous coronary intervention. Eleven eligible publications, including 3,008 participants, were finally evaluated. Eight studies conducted adjustment of risk ratio for potential cardiovascular risk factors, 5 studies defined OSA groups as AHI (apnea hypopnea index) ≥15/hour, whereas the remaining eligible studies used AHI ≥5/hour, AHI ≥10/hour, or AHI ≥30/hour as the criteria...

Importance: Growing evidence suggests an association between sleep-disordered breathing (SDB) and cognitive decline in elderly persons. However, results from population-based studies have been conflicting, possibly owing to different methods to assess SDB or cognitive domains, making it difficult to draw conclusions on this association. Objective: To provide a quantitative synthesis of population-based studies on the relationship between SDB and risk of cognitive impairment...

Sleep-disordered breathing (SDB) is a highly prevalent condition, and is associated with many debilitating chronic diseases. The role of untreated obstructive sleep apnea (OSA) in arterial hypertension has been recognized in international guidelines. Treatment with continuous positive airway pressure (CPAP) is associated with clinically-relevant reductions in blood pressure. In heart failure (HF), SDB is associated with worse prognosis and increased mortality. Major HF guidelines recommend that patients should be treated for sleep apnea to improve their HF status...

Although noninvasive ventilation (NIV) has been used since the 1950s in the polio epidemic, the development of modern bilevel positive airway pressure (BPAP) devices did not become a reality until the 1990s. Over the past 25 years, BPAP technology options have increased exponentially. The number of patients receiving this treatment both in the acute setting and at home is growing steadily. However, a knowledge gap exists in the way the settings on these devices are adjusted to achieve synchrony and match the patient's unique physiology of respiratory failure...

Obstructive sleep apnea (OSA) is a nocturnal breathing disorder that is associated with cognitive impairment. The primary determinants of cognitive deficits in OSA are thought to be sleep disruption and blood gas abnormalities. Cognitive impairment is also seen in other disorders that are characterised primarily by sleep disturbance (e.g., sleep restriction/deprivation, insomnia) or hypoxia/hypercarbia (e.g., chronic obstructive pulmonary disease (COPD)). Assessment of the cognitive deficits observed in these other disorders could help better define the mechanisms underlying cognitive deficits in OSA...
