| Low Vitamin D may increase Risk of Alzheimer's
| 17 May 2007 |
Low levels of Vitamin D are strongly associated with a greater likelihood of being depressed and also developing Alzheimer's disease in elderly individuals.
Consuelo H.Wilkins, MD, of Washington University School of Medicine, St.Louis, Missouri, and colleagues studies 80 seniors, of whom 40 had signs of dementia. She found that 58% of the subjects were deficient in vitamin D, with blood levels below 20 ng/ml. People with low levels of vitamin D were almost 12 times more likely to suffer from depression, compared with people who had high levels of the vitamin. In addition, low vitamin D levles were strongly associated with two of four tests given to measure cognitive performand and Alzheimer's disease.
