Sleep quality and dementia

New research suggests that disrupted sleep in one's 30s and 40s may lead to memory and cognitive problems a decade later. While the study doesn't establish a causal relationship, it highlights an association between sleep quality and cognitive health.

Researchers followed 526 participants for 11 years and found that those with the most disrupted sleep had over twice the odds of experiencing poor cognitive performance later in life. 

This emphasizes the importance of addressing sleep quality for long-term cognitive health.

The study highlights the need for further research to understand the connection between sleep and cognition at different life stages.
