Can sleep loss cause early brain aging
A new study reveals that lack of sleep does not affect the brain in the same way for everyone, as the extent of damage depends on genetic differences, particularly the AQP4 gene responsible for regulating brain fluids. The findings showed that some individuals who sleep only a few hours lose gray matter more rapidly and experience faster declines in memory and cognitive functions, while others tolerate variations in sleep better. This suggests that genes and sleep interact to determine the rate of brain aging.
