This blog is based off of the AAST 2019 Annual Meeting Session "Obstructive Sleep Apnea and Stroke: Evidence, Mechanisms, and Treatment Strategies." For more information on this session and other session recordings click here. Ischemic stroke (or acute stroke) is the second leading cause of long-term disability. Many who suffer from ischemic stroke also have obstructive sleep apnea (OSA). Currently, ischemic stroke treatment therapies have a very limited therapeutic window and aren’t widely applicable to most patients. The treatment of OSA in patients with acute ischemic stroke is now being looked to as a novel, therapeutic approach to preventing stroke.
