A sleeping beast: Obstructive sleep apnea and stroke.

Up to two-thirds of patients who have had a stroke have obstructive sleep apnea (OSA) afterward. These patients have worse outcomes than those without OSA in terms of short-term morbidity, functional and cognitive recovery, and mortality rates over the long term. Following a stroke, identifying OSA and treating it with positive airway pressure, if possible, are important clinical goals.
