Dementia is one of the major causes of disability and dependency among older people worldwide, affecting thinking and behaviors as you age. But what if you could stop this degenerative disease in its tracks?
A world-first study from the University of South Australia could make this a reality as new genetic research shows a direct link between dementia and a lack of vitamin D.
Investigating the association between vitamin D, neuroimaging features, and the risk of dementia and stroke, the study found:
- low levels of vitamin D were associated with lower brain volumes and an increased risk of dementia and stroke
- genetic analyses supported a causal effect of vitamin D deficiency and dementia.
- in some populations as much as 17% of dementia cases might be prevented by increasing everyo...
