University of Liège study links nighttime awakenings to Alzheimer's risk

A new study from the University of Liège has identified a link between frequent nighttime micro-awakenings and a higher genetic risk for developing Alzheimer's disease, particularly in middle-aged individuals.

Researchers analyzed sleep patterns in over 500 healthy participants. While the correlation was significant in middle-aged subjects, the same connection was not observed in younger adults, suggesting that the relationship between sleep and neurodegenerative processes may change with age.

Researchers emphasized that these findings do not prove that waking up during the night causes Alzheimer's. Further studies are required to determine if sleep disturbances play a role in the development of neurodegenerative processes or if they are an early symptom of the disease. Other recent research has also noted connections between sleep structure changes and biological markers of Alzheimer's, such as beta-amyloid protein deposition.
