Study Links Sleep Quality in Midlife to Later Cognitive Health

A study published in Neurology has revealed that adults who experienced interrupted sleep in their 30s and 40s performed worse on cognitive function tests a decade later. Researchers evaluated the sleep patterns of over 500 adults from 2003 to 2005 and followed up with cognitive assessments eleven years later, testing memory, recall, perception, and organizational skills.

The findings indicated that individuals with a higher incidence of sleep disturbances were more likely to exhibit signs of cognitive decline compared to those with fewer disturbances. Interestingly, the length of sleep did not appear to influence these outcomes. The researchers concluded that the quality of sleep during early to midlife significantly affects cognitive health in later years. The study received funding from the NHLBI.
