Researchers from the Indian Council of Medical Research-National Institute of Nutrition (ICMR-NIN) found that deficiencies in vitamin D and B-vitamins increase dementia risk.
These findings suggest that monitoring nutrient levels in middle-aged adults could provide a critical window for intervention to prevent long-term neurological decline.
The study focused on a sample of 556 middle-aged and older adults in Telangana [1]. Scientists found that low levels of vitamin D and specific B-vitamins, including B2, B6, and B9, are associated with a higher risk of cognitive decline and dementia [2, 3].
Experts said that these specific nutrient deficiencies may impair brain health, which increases the likelihood of developing dementia [3, 4]. Because these deficiencies can be identified through medical testing, researchers are calling for early blood-screening and consistent nutrient monitoring [2, 4].
Early detection allows for the correction of these deficiencies through diet or supplementation. This proactive approach may potentially lower the long-term neurological risk for at-risk populations [3, 4].
The collaborating scientists said the findings from New Delhi emphasize the need for better nutritional awareness among older populations in India [1].
“Deficiencies in vitamin D and B-vitamins are associated with a higher risk of cognitive decline.”
This research highlights a shift toward preventative neurology by focusing on metabolic markers. If nutrient deficiencies are a significant driver of cognitive decline, public health strategies may move toward routine vitamin screening for middle-aged adults to mitigate the growing global burden of dementia.
