Northern Countries: Environmental Risk Factors Behind Geographical Variations in Dementia Risk? (BBC News / Epidemiology)

Summary

People living further north appear to be more likely to develop dementia. Scientists mapped prevalence of dementia in Scotland among 37,000 people born in 1921. A second study involved over 26,000 Swedish twins living in different parts of that country. These two studies indicate that individuals living at higher latitudes tend to be more likely to suffer from dementia, perhaps due to environmental factors such as relative lack of sunlight (possibly implicating lower Vitamin D, which is a suspected risk factor previously identified) increasing the level of dementia risk.
