BACKGROUND: It has been estimated that the prevalence of Alzheimer disease (AD) and related dementias will triple by 2035, unless effective interventions or treatments are found for the neurodegenerative disease. Understanding sleep changes as a marker for both AD risk and progression is a burgeoning area of investigation. Specifically, there is emerging evidence that both sleep disturbances and the APOE ε4 allele are associated with increased dementia risk. Previous research has suggested that in AD, individuals carrying the APOE ε4 allele have decreased sleep quality compared to individuals without the APOE ε4 allele...

PURPOSE: To explore the validity of cone beam computed tomography (CBCT) as one of many predictive tools that can be used (alone or in conjunction) to help in identifying high-risk cases of obstructive sleep apnea (OSA) that should get the earliest possible referral to a sleep specialist for standard diagnostic polysomnography, and to identify imaging airway parameters that may be predictive of OSA severity. METHODS: Using a case-control design, 45 subjects matched by age and sex (22 OSA cases and 23 controls) were included in this study...

OBJECTIVE: Sleep-disordered breathing (SDB) is among the most common diseases and includes a group of pathological conditions that form a severity continuum from primary snoring (PS) to obstructive sleep apnea (OSA). SDB presents a multifactorial etiology and in children, it is often linked to adenotonsillar hypertrophy, which may lead to an alteration of the breathing pattern. Therefore, several studies hinted at the existence of a correlation between SDB and the alteration of craniofacial growth...

Rapid eye movement sleep behavior disorder (RBD) is thought to be one of the most frequent preceding symptoms of Parkinson's disease (PD). However, the prevalence of RBD in PD stated in the published studies is still inconsistent. We conducted a meta and meta-regression analysis in this paper to estimate the pooled prevalence. We searched the electronic databases of PubMed, ScienceDirect, EMBASE and EBSCO up to June 2016 for related articles. STATA 12.0 statistics software was used to calculate the available data from each research...

PURPOSE: Obstructive sleep apnoea (OSA) is a prevalent disorder, characterised by collapse of the upper airways during sleep. The impact of sleep-disordered breathing on pulmonary function indices is however currently not well described. The aim of the study was to evaluate diurnal change in lung function indices in a cohort of patients with OSA and relate pulmonary function changes to disease severity. METHODS: 42 patients with OSA and 73 healthy control subjects participated in the study...

The French Society of Research and Sleep Medicine (SFRMS) organized a meeting on obstructive sleep apnea syndrome (OSAS) in children. A multidisciplinary group of specialists (pulmonologist, ENT surgeons, pediatricians, orofacial myofunctional therapists, neurophysiologists, and sleep specialists) reached a consensus on the value of isolated or clustered clinical symptoms and of questionnaires completed by parents in the clinical diagnosis and in assessing the severity of OSAS. Are clinical history with validated questionnaires and a rigorous physical examination sufficient to suspect OSAS, to appreciate its severity, and finally to confirm the diagnosis? Usually, a sleep recording of respiratory parameters remains mandatory for the diagnosis of OSAS to be made...

INTRODUCTION: Noise is one of the factors that can seriously disturb sleep, and sound volume is an important factor in this context. One strategy involves avoiding exposure to sounds in the night, while entail the minimization of background noise in a bedroom. The goal of this study was to investigate the effect of systematic sound attenuation on nocturnal sleep by influencing sound volume and reverberation within the context of room acoustics. MATERIALS AND METHODS: On this basis, we designed a randomized, controlled crossover trial investigating 24 healthy sleepers (15 men and 9 women, aged 24...

Obstructive sleep apnea is a sleep disorder which may lead to various results. While some studies used real-time systems, there are also numerous studies which focus on diagnosing Obstructive Sleep Apnea via signals obtained by polysomnography from apnea patients who spend the night in sleep laboratory. The mean, frequency and power of signals obtained from patients are frequently used. Obstructive Sleep Apnea of 74 patients were scored in this study. A visual-scoring based algorithm and a morphological filter via Artificial Neural Networks were used in order to diagnose Obstructive Sleep Apnea...

To investigate whether seizure lateralization affects sleep macrostructure in patients with left and right temporal lobe epilepsy (TLE), as rapid eye movement (REM) sleep is shorter in patients with right hemispheric cerebral infarction than with left. We retrospectively analyzed data from 16 patients with TLE (6 men and 10 women aged 34.9 ± 11.4 years) who underwent polysomnography as well as long-term video electroencephalography. Ten patients were diagnosed with left TLE and six patients with right TLE...

OBJECTIVE: Menopause is widely believed to be an established cause of sleep disorders, but evidence for this theory is inconclusive. Attributing any sleep problem to normal processes of menopause may lead to underdiagnosis of treatable sleep disorders in midlife women. This study uses detailed longitudinal data on sleep and menopausal health from participants in the Sleep in Midlife Women Study to investigate whether risk and severity of sleep-disordered breathing increase with progression through menopause, accounting for changes in age and body habitus...

Resistant hypertension is defined as blood pressure that remains above 140/90 mmHg in spite of the concurrent use of three antihypertensive agents of different classes at optimal dosing, of which one should be a diuretic. Accordingly, it is not synonymous with uncontrolled hypertension. Among a variety of risk factors, obstructive sleep apnea (OSA), which is a common type of sleep-disordered breathing, has been recognized a well-established risk factor for resistant hypertension. Indeed, both European and American guidelines for the management of arterial hypertension stated that OSA is a modifiable cause of resistant hypertension...

OBJECTIVE: Primary aldosteronism (PA) and sleep apnea syndrome (SAS) are common form of secondary hypertension. Some papers reported the group of high risk of SAS was higher rate of complication with PA than that of low risk of SAS. However, there are few reports which evaluated CPAP implementation rate of the PA patients with SAS diagnosing by Polysomnography (PSG). We aim to clarify clinical characteristics of patients of PA with SAS. DESIGN AND METHOD: We screened with Apnomonitor 284 PA patients who underwent adrenal venous sampling (AVS)...

OBJECTIVE: Current study sought to evaluate the effects of obstructive sleep apnea (OSA) plus hypertension (HTN) on prevalent cardiovascular diseases (CVD). DESIGN AND METHOD: This was a cross-sectional study and a total of 1889 subjects were enrolled. The apnea-hypopnea index (AHI) was measured by polysomnography and OSA degree was classified as mild (AHI 5-14.9) and moderate-severe (AHI ≥ 15), and AHI < 5 was considered no-OSA. Mean and lowest oxyhemoglobin saturation (SaO2) was detected by pulse oximetry...

OBJECTIVE: Obstructive sleep apnoea (OSA) is known to commonly co-exist with primary aldosteronism (PA), but it is unknown if treatment via mineralocorticoid receptor blockade or adrenalectomy (for aldosterone producing adenoma, APA), improves sleep apnoea parameters in these patients. We therefore aimed to determine if specific medical or surgical treatment of PA improves OSA, as measured by the apnoea hypopnoea index (AHI). DESIGN AND METHOD: Patients undergoing diagnostic workup for PA were recruited if they had symptoms suggestive of OSA...

OBJECTIVE: Obstructive sleep apnea (OSA) causes blood pressure (BP) surge while OSA episode occurs which could lead to increase the cardiovascular risk. We recently developed a triggered nocturnal BP monitoring (TNP) that initiates BP measurement when oxygen desaturation falls below a variable threshold. In this study, we evaluated the distribution of the nocturnal BP parameters measured by TNP, classification of nocturnal hypertension(HT) and its reproducibility. DESIGN AND METHOD: 147 outpatients in whom polysomnography (PSG) was planned for the diagnosis of OSA (mean age 59...
