Abstract
In the present review we address several mechanisms that could potentially explain these discrepancies. We focus in depth on mechanisms of central SNS reinforcement in OSA including dysfunctional baroreflex response, and inflammatory processes within the brain centres controlling the cardiovascular system. Additionally, novel insights into physiology of cerebral blood flow regulation are proposed, including the role of short-term blood pressure changes, heart rate fluctuations and baroreflex alterations. Finally, a potential role of increased blood flow pulsatility in cerebrospinal fluid circulation changes and its influence on SNS drive is highlighted. The presented review provides insights into how sympathetic nervous system reinforcement in OSA promotes maladaptive mechanisms that could alter cerebral perfusion regulation, and result in functional and structural cerebral changes.
