Sleep Apnea and Stroke
Obstructive sleep apnea, a form of sleep-disordered breathing, is associated with multiple major stroke risk factors but is also an independent risk factor for stroke.
Cardioembolic stroke is far more common in patients with OSA than in patients without OSA.
Obstructive sleep apnea doubles the risk of stroke in men.
Men with moderate to severe sleep apnea were about three times more likely to have a stroke than men with mild or no sleep apnea.
Sleep apnea is common in people with silent strokes and small lesions in the brain.
An estimated 70% of acute ischemic stroke patients may have sleep apnea.
Sleep apnea may negatively affect the short and long-term outcome in acute ischemic stroke patients.
Early treatment of sleep apnea may help reduce risk of silent strokes in these patients.
