Summary

This June 2025 review explores how different forms of programmed cell death (PCD) – like apoptosis, autophagy, ferroptosis, and pyroptosis – might contribute to cognitive problems in people with obstructive sleep apnea (OSA). Repeated low oxygen levels during sleep (called intermittent hypoxia) may trigger these cell death processes in key brain regions. The study suggests that targeting these pathways with drugs could offer new treatments to protect brain function in OSA patients.

Key Takeaways

✅ Sleep apnea can damage brain cells through various types of cell death
✅ Memory, attention, and emotional control are often affected in people with OSA
✅ Brain scans show shrinkage or damage in important memory-related areas
✅ Inflammation, oxidative stress, and iron overload play key roles
✅ Targeting these cell death mechanisms may help improve cognition in OSA

Why It Matters for You

If you or a loved one has sleep apnea, managing it isn’t just about better rest – it could also help protect your brain health. This study highlights the importance of treating OSA to reduce the risk of memory loss or other cognitive issues.
