Vitamin D deficiency in older persons doubled the risk of developing
dementia and Alzheimer's disease, according to research published in
the journal Neurology.
Vitamin D is commonly sourced from exposure to the sun, as well as
consumption of eggs, milk and fatty fish such as tuna or mackerel,
among other foodstuffs.
Researchers looked at concentrations of the vitamin among 1658 elderly
adults who were free from dementia and cardiovascular disease.
Within six years, 171 participants had developed dementia, including
102 cases of Alzheimer's. The researchers found the risk of developing
dementia was markedly increased for those who had deficient or
severely deficient vitamin D levels.
The study is the first to confirm a strong link between the role of
vitamin D in preventing or delaying dementia.
"We expected to find an association between low Vitamin D levels and
the risk of dementia and Alzheimer's disease, but the results were
surprising - we actually found that the association was twice as
strong as we anticipated," said Dr David Llewellyn, who led the
research for the University of Exeter.
"Our findings are very encouraging, and even if a small number of
people could benefit, this would have enormous public
healthimplications given the devastating and costly nature of dementia."
Dementia is emerging as a key public health issue as populations
increasing in age around the world. These challenges were discussed
recently during a televised debate for Protection Now
