Sleep and Breathing Disturbances in Children With Leigh Syndrome: A Comparative Study
(Elsevier, 2022)
Background: Leigh syndrome (LS) is a progressive neurodegenerative mitochondrial disease character-ized by necrotizing lesions affecting different parts of the central nervous system, especially in the brainstem and basal ...
Effects of the CPAP Treatment on the NON-REM Sleep Microstructures in Patients with Severe Apnea-Hypoapnea Syndrome
(OMICS International, 2014-03)
Sleep quality is affected in patients with sleep apnea- hypopnea syndrome (SAHS) with nocturnal and diurnal consequences. Most of these patients who are treated with positive airway pressure (CPAP) return to normal sleep ...
Sleep-wake stages classification using heart rate signals from pulse oximetry
(Elsevier, 2019-10)
The most important index of obstructive sleep apnea/hypopnea syndrome (OSAHS) is the apnea/hyponea index (AHI). The AHI is the number of apnea/hypopnea events per hour of sleep. Algorithms for the screening of OSAHS from ...
Cyclic Alternating Pattern Associated with Catathrenia and Bruxism in a 10-Year-Old Patient
(American Academy of Sleep Medicine, 2017)
Cyclic alternating pattern (CAP) is widely recognized as an expression of sleep instability in electroencephalogram activity during non-rapid eye movement sleep. We report a case with sequences of CAP followed by bruxism ...
Using time causal quantifiers to characterize sleep stages
(Elsevier, 2021-05)
Sleep plays a substantial role in daily cognitive performance, mood, and memory. The study of sleep has attracted the interest of neuroscientists, clinicians and the overall population, with an increasing number of adults ...
Discovery of key whole-brain transitions and dynamics during human wakefulness and non-REM sleep
(Nature Publishing Group, 2019-03-04)
The modern understanding of sleep is based on the classification of sleep into stages defined by their electroencephalography (EEG) signatures, but the underlying brain dynamics remain unclear. Here we aimed to move ...
Sleep Disordered Breathing in Four Resource-Limited Settings in Peru: Prevalence, Risk Factors, and Association with Chronic Diseases
(Oxford University Press, 2015)
STUDY OBJECTIVES: Sleep disordered breathing (SDB) is a highly prevalent condition in high-income countries, with major consequences for cardiopulmonary health, public safety, healthcare utilization, and mortality. However, ...
Modeling regional changes in dynamic stability during sleep and wakefulness
(Elsevier, 2020-07-15)
Global brain states are frequently placed within a unidimensional continuum by correlational studies, ranging from states of deep unconsciousness to ordinary wakefulness. An alternative is their multidimensional and ...
Neuroendocrine-metabolic dysfunction and sleep disturbances in neurodegenerative disorders: Focus on Alzheimer's disease and melatonin
(Karger, 2018-10)
Alzheimer's disease (AD) is associated with altered eating behavior and metabolic disruption. Amyloid plaques and neurofilament tangles are observed in many hypothalamic nuclei from AD brains. Some of these areas ...
Isovolemic hemodilution in chronic mountain sickness acutely worsens nocturnal oxygenation and sleep apnea severity
(American Academy of Sleep Medicine, 2022)
STUDY OBJECTIVES: Chronic mountain sickness (CMS) is commonly observed among Andean and other highland populations. Sleep-disordered breathing (SDB) is highly prevalent at high altitude, and SDB and nocturnal hypoxemia ...
