Michigan Health Lab: Stroke onset while asleep does not seem to be the direct link between sleep apnea and stroke.
“When someone wakes up with stroke symptoms, it’s unclear when the event actually began,” explains first author Sonja Schuetz, M.D., M.S., an assistant professor of neurology at Michigan Medicine. This is known as wake-up stroke, and was reported in 30% of the stroke survivors in the study. “Every minute matters in stroke care, so wake-up strokes complicate treatment. We wanted to explore if there’s a link between wake-up stroke and obstructive sleep apnea.”uofmhealth.org
