Sleep-Disordered Breathing After Stroke
نویسنده
چکیده
Sleep-disordered breathing is common after stroke and most often presents as obstructive sleep apnea (OSA), with an estimated prevalence between 43% and 70% compared with 4% and 24% in the general population. OSA is the result of partial or complete closure of the upper airway while attempting to breathe during sleep. It is characterized by snoring, hypopnea, and apnea with intermittent awakening accompanied by gasping or choking. Daytime sleepiness and fatigue are common features as well. The severity of OSA is measured using the apnea–hypopnea index, oxygen desaturations, and arousals during each hour of sleep. OSA after stroke has been shown to increase poststroke mortality and morbidity. Untreated, OSA may worsen cognition, functional outcome, and mood after stroke.

Sleep-disordered breathing and stroke.
Sleep-related breathing disorders are strongly associated with increased risk of stroke independent of known risk factors. The direction of causation favors sleep-disordered breathing leading to stroke rather than the other way around, although definitive proof of this awaits the results of prospective cohort studies. If causal, even a moderately elevated risk of stroke coupled with the high pr...

I nterest in abnormal breathing after stroke has a long history dating back at least to the observations of John Cheyne in 1818. In recent years this interest has been reawakened by a number of publications on the relations between sleep disordered breathing (SDB) and stroke. These studies have been of two main types—those investigating the possible increased risk of stroke in individuals with ...

R ecently, sleep-disordered breathing and nocturnal hypoxia have been recognized to increase the risk of cerebrovascular disease. Kirkham et al reported that nocturnal hypoxemia was a predictor of future cerebrovascular events in sickle-cell disease. However, it remains unclear whether nocturnal hypoxemic episodes directly lead to nocturnal onset stroke, because other predisposing conditions mi...

In acute stroke, OSA has been found to impair rehabilitation and increase mortality but the effect of central apnea is more unclear. The aim of the present study was to evaluate the feasibility of using limited ambulatory recording system (sleep mattress to evaluate nocturnal breathing and EOG-electrodes for sleep staging) in sleep disordered breathing (SDB) diagnostics in mild acute cerebral i...
