Sleep quality linked to dementia


New research suggests that sleep disruptions between the ages of 30 and 40 can lead to cognitive and memory problems a decade later. Although the study does not establish a causal relationship, it highlights an association between sleep quality and cognitive health.

The researchers followed 526 participants for 11 years and found that those with the most disrupted sleep were more than twice as likely to experience poor cognitive performance later in life.

Sleep quality, rather than quantity, plays an important role in cognitive health.

The study underscores the need for further research to understand the relationship between sleep and cognition at different stages of life.
