Although sleep makes up a modest portion of our daily routine, a recent study discovered that it can have a variety of effects, particularly on individuals in their 30s and 40s. According to a recent study published in Neurology, those who had sleep disturbances in their 30s and 40s may be more vulnerable to memory and cognitive problems ten years later.
The study shows a strong correlation between poor sleep quality and cognitive loss, even if it doesn’t prove a cause-and-effect link.
The University of California, San Francisco study author, Yue Leng, stressed the need of comprehending the relationship between sleep and cognition at an earlier age, particularly in light of the fact that Alzheimer’s disease exhibits brain abnormalities long before symptoms materialize.
Over an 11-year period, 526 participants, with an average age of 40, were followed up on. With an average sleep length of six hours, the researchers looked at the subjects’ sleep duration as well as quality. Using wrist sleep monitors, sleep diaries, and a sleep quality survey, the quality of the sleep was evaluated. A sleep quality survey revealed that over 46 percent of individuals had poor quality sleep. Tests of thinking and memory were administered in addition to the examination of sleep fragmentation, which measures the frequency of brief sleep disruptions.
On the basis of their sleep fragmentation ratings, the participants were split up into three groups. Ten individuals in the group with the least disturbed sleep showed impaired cognitive performance ten years later, but 44 individuals in the group with the most disturbed sleep did not. After adjusting for a number of variables, those who experienced the most sleep disruption were more than twice as likely to have poor cognitive function as people who experienced the least disruption.
Surprisingly, there was no discernible difference in the group with moderately disrupted sleep compared to the group with the least disturbance in terms of cognitive ability at midlife. The results highlight the importance of quality sleep over quantity for maintaining cognitive function in middle age.
