Research from the University of Liege indicates a link between frequent nighttime micro-awakenings and a higher genetic risk of Alzheimer's disease in older adults.

•Research from the University of Liege in Belgium found a link between micro-awakenings and Alzheimer's risk.
•Adults aged 50–69 with frequent micro-awakenings showed higher genetic risk for Alzheimer's even without symptoms.
•No similar link was found in the younger study group aged 18–31.
•The findings were published in the journal Sleep.

Overview

•On September 15, 2026, research from the University of Liege in Belgium regarding micro-awakenings and Alzheimer's risk was reported.
•Researchers studied the sleep patterns of over 500 people across two age groups: 18–31 years and 50–69 years.
•Adults in the 50–69 age group who experienced frequent micro-awakenings had a higher genetic risk for Alzheimer's disease.
•Micro-awakenings are defined as brief brain awakenings during sleep cycles that may not fully wake the person but disrupt sleep quality.
•Researchers stated that it cannot yet be concluded that frequent micro-awakenings cause Alzheimer's due to study limitations.
•Experts state sleep is vital for brain health as it allows the brain to store memories and remove waste related to Alzheimer's risk.
•People experiencing memory problems that impact daily life, such as difficulty conversing or getting lost in familiar places, should consult a doctor.
•Recommended brain health practices include exercising at least 150 minutes per week, eating healthy food, avoiding smoking, limiting alcohol, and treating sleep apnea.
