[Prevalence of breathing disorders during sleep in patients with cerebrovascular disease].

More of the half of the stroke patients have sleep-disordered breathing. Among them, snoring and the obstructive sleep apnea syndrome (OSAS) have been the most studied. From different epidemiologic studies focused in finding a casual relationship between sleep-disordered breathing and stroke result evidences that at least establish that snoring and principally OSAS are a cause and consequence of stroke. The possibility to modify the respiratory disorder with treatment emphasizes the importance of this association.
