Obstructive Sleep Apnea and Wake-up Stroke - A 12 Months Prospective Longitudinal Study.

Background: Wake-up stroke (WUS) are strokes that are noted upon awakening in patients previously going to bed in a normal state of health. The role of sleep abnormalities in WUS is uncertain. The objective was to determine clinical characteristics, respiratory abnormalities during sleep and outcomes in patients with WUS versus non-WUS.
