Can a lack of Vitamin D lead to Dementia?

Vitamin D deficiency is something I talk to my patients about all the time especially because of the limited amount of sunlight we get in the winter time here in the Midwestern part of the United States. I regularly run into patients who have low-vitamin D levels. I know I may at times sound like a broken record when it comes to vitamin D, but it is a major concern because a lack of vitamin D can be linked to many illnesses. The also CDC states that about 33% of the people in the US not get the sufficient amounts of vitamin D. According to a study published in Neurology that says that low vitamin D levels are linked to the development of Alzheimer’s disease. Alzheimer’s is the most common form of dementia affecting roughly 5.3 million Americans these are figures are from the Center for Disease and Prevention. In the study, the researchers tested 1,658 people who did not have dementia and were over the age of 65. The vitamin D levels were recorded, and the study checked back with the subjects about five years later. After five years, 171 of the participants had been diagnosed with dementia. The study revealed that the subjects with low levels of vitamin D were 53% more likely to develop dementia and those with extremely low levels were 125% likely. More studies will be needed to establish a direct correlation, but based on this study I would say that low-levels of vitamin D has a definite impact on our health. Vitamin D can be obtained from exposure to sunlight, and by eating foods like fish, milk, eggs and cheese.
