Daytime Sleepiness and Dementia: Is There a Cardiovascular Link?
Excessive daytime sleepiness (EDS) is more than just feeling drowsy during the day. Research has hinted at a connection between EDS and an increased risk of dementia. But what's the underlying cause? The CALERIE study delved deep into this, examining the potential role of cardiovascular health in this relationship. Over a 12-year period, the study observed older adults without dementia or vascular diseases. The findings were intriguing: those with EDS had a higher risk of developing dementia, especially types with a vascular component. While cardiovascular factors did play a role, they only accounted for a small portion of the link between EDS and dementia. This suggests that while heart health is important, other factors also contribute to the relationship between daytime sleepiness and dementia risk.
