Low vitamin D associated with faster decline in cognitive function

RATE THIS! +35

Researchs have found that Vitamin D insufficiency was associated with faster decline in cognitive functions among a group of ethnically diverse older adults. Research has increasingly examined the association between vitamin D and a variety of health outcomes, including dementia and cognitive decline.

 
The authors note limitations to their study including that they did not directly measure dairy intake, sun exposure or exercise, each of which can influence vitamin D levels. “Our data support the common occurrence of VitD [vitamin D] insufficiency among older individuals. In addition, these data show that African American and Hispanic individuals are more likely to have VitD insufficiency or deficiency.
 
“Independent of race or ethnicity, baseline cognitive ability, and a host of other risk factors, VitD insufficiency was associated with significantly faster declines in both episodic memory and executive function performance, which may correspond to elevated risk for incident AD [Alzheimer disease] dementia.
 
“Given that VitD insufficiency is medically correctable, well-designed clinical trials that emphasize enrollment of individuals of nonwhite race/ethnicity with hypovitaminosis D could be useful for testing the effect of VitD replacement on dementia prevention,” the study concludes.

VitD is expected to be required for many functions and it is not a surprise that brain also requires normal levels - this again points out that balanced diet and lifestyle are the key for human health Reply
