  • Summary

  • Listen as we investigate the correlation between obstructive sleep apnea (OSA) severity and cognitive decline (CD), specifically focusing on vigilance. The study utilized polysomnography (PSG) to identify risk factors for CD in patients with suspected OSA and compared these factors across different OSA severity levels. The researchers employed the psychomotor vigilance task (PVT) to measure established CD and analyzed several risk factors, including oxygen desaturation and sleep arousal. Their findings suggest a link between severe risk factors identified via PSG and PVT-determined CD, particularly at higher OSA severities. Future studies are proposed to validate these findings and explore the relationship in other cognitive domains.
