Researchers have found that people in their thirties and forties who experience sleep problems may have issues with memory and thinking as early as ten years later. The study, published in the journal Neurology, revealed that those with interrupted sleep were more than twice as likely to perform poorly on cognitive tasks compared to those who had uninterrupted sleep. Assistant professor Yue Leng emphasized the importance of sleep for brain health, stating that the signs of Alzheimer’s disease begin to accumulate in the brain several decades before symptoms begin.
The new research took into account both the duration and quality of participants’ sleep, as well as their subsequent memory and thinking tasks. It was found that those who had the most interrupted sleep were indeed more likely to perform poorly on cognitive tasks a decade later. However, it is important to note that the researchers were not able to draw proper conclusions about the differences between genders or ethnic groups due to the limitation of a small number of subjects in the study.
In conclusion, it appears that sleep plays a crucial role in maintaining cognitive health in middle age. It is essential to ensure good quality sleep habits and address any underlying sleep disorders promptly to minimize potential negative effects on cognitive function in later years.
