Depressed people are twice as likely to develop certain forms of dementia, such as Alzheimer’s disease.
A new study found that 22 percent of participants who had depression at the beginning of the study ended up developing dementia, compared to about 17 percent of those who were not depressed.
Food Consumer reports:
“One real possibility ... is that depression and dementia share some common cause ... vitamin D may be the link between the two. [Researchers] found that in November, people with serum levels of vitamin D falling in the highest quartile were 49 percent less likely to experience depression ... Additionally, vitamin D helps prevent dementia, such as that exhibited in those with Alzheimer's disease.”
