According to new research, low levels of a particular form of vitamin D could be linked with Alzheimer’s disease.
A team from London’s Kingston University collaborated with researchers from Brighton and Sussex Medical School and the Sussex Partnership NHS Foundation, and analysed blood samples from patients with Alzheimer’s over a six-month period.
They compared the results of individuals who were taking medication with those who were not being treated with any drugs and also a further group who did not have the condition. The results showed that Alzheimer’s patients who were not taking medication had very low levels of vitamin D2 – the type originating from food such as oily fish, rather than that obtained from exposure to the sun.
Those individuals who were either being treated with drugs to control their Alzheimer’s or who didn’t have the condition at all showed far higher levels of vitamin D2. Lead researcher Professor Declan Naughton commented: “Further investigations are now needed to determine whether simple dietary advice or giving a specific supplement could restore beneficial levels in Alzheimer’s patients.” The results were published in Current Alzheimer Research.
