Stroke and sleep apnea: Strange bed partners

Stroke and sleep apnea manStroke researchers now know that sleep apnea is very common after stroke. We have found that about 75% of stroke patients have sleep apnea. This is important because sleep apnea has wide-ranging consequences for stroke patients.

Why it’s important for sleep apnea to be diagnosed in stroke patients

Sleep apnea is a predictor of poor outcomes following stroke, such as greater disability and higher mortality. The exact reasons for this are unknown at this time and warrant further study.

In addition, it is possible that sleep apnea contributes to increased stroke risk by promoting atherosclerosis, hyper coagulability (an abnormally increased tendency for the blood to clot) and adverse effects on cerebral hemodynamics (the forces involved in the circulation of blood in the brain).  Continue reading
