Frequent Nighttime Waking Linked to Alzheimer’s Risk, Study Suggests
New research from the University of Liège indicates a potential link between frequent micro-awakenings during sleep and an increased risk of Alzheimer’s disease in older adults.
A study published in the journal Sleep and reported by Khaosod Online Thailand on September 15, 2026, has highlighted a potential correlation between frequent nighttime waking and Alzheimer’s disease. Researchers from the University of Liège in Belgium monitored the sleep patterns of over 500 participants, divided into age groups of 18–31 and 50–69, using EEG technology to track brain activity.
The findings indicate that adults aged 50–69 who experience frequent 'micro-awakenings'—brief moments of brain arousal during sleep cycles that may not lead to full consciousness—show a higher genetic risk for Alzheimer’s, even in the absence of clinical symptoms. Interestingly, this specific link was not observed in the younger participant group.
For residents and travelers in Thailand, this research serves as a reminder of the importance of sleep quality for long-term cognitive health. However, the researchers emphasize that the study has limitations and it cannot yet be concluded that frequent micro-awakenings directly cause Alzheimer’s disease. Further investigation is required to fully understand the causal relationship. As this is a scientific observation rather than a diagnostic tool, individuals concerned about their sleep patterns or cognitive health should consult with a qualified medical professional rather than drawing personal conclusions from these findings.
