Disrupted Sleep: The ideal number of hours to sleep for good health has long been a topic of discussion. But in recent years, specialists have argued that one should prioritise the quality of sleep over the quantity of sleep.
Recent Study on Disrupted Sleep
According to recent research that was published in the journal Neurology, persons who have sleep disturbances in their 30s and 40s may be more likely to experience memory and cognitive issues ten years later.
The study underlined the significance of getting enough sleep for an individual since poor sleep is associated with potential brain abnormalities.
The 11-year study, which included 526 participants with an average age of 40, found a correlation but not a direct cause-and-effect relationship between sleep disruption and cognitive deterioration.
The study’s lead author, Dr. Yue Leng of the University of California, San Francisco, emphasised the importance of comprehending the relationship between sleep and cognition at a younger age, especially in light of the fact that Alzheimer’s disease indications can be found in the brain decades before symptoms arise.
Through a variety of techniques, such as wrist activity monitors, sleep diaries, and sleep quality assessments, the study assessed the individuals’ sleep patterns.
Even though participants slept for an average of six hours, 46% of them had disrupted sleep. The study examined sleep fragmentation by quantifying sleep disruptions and found that participants’ average sleep fragmentation was 19%.
Even after accounting for variables including age, gender, race, and education, the study showed that people who experienced the greatest sleep disruption had more than double the likelihood of having poor cognitive function ten years later than people who experienced the least disruption.
Dr. Leng emphasised the necessity for more investigation into the connection between sleep disorders and cognitive functioning at various phases of life. The study acknowledged many limitations, such as a limited sample size and the absence of gender or race-based disparities. – DISRUPTED SLEEP
