ICMR-NIN study links vitamin deficiencies to cognitive decline in elderly
Healthy ageing requires attention not only to disease management but also to nutritional well-being, says ICMR-NIN Director Bharati Kulkarni
A recent study conducted by researchers at the ICMR-National Institute of Nutrition (NIN) in Hyderabad has discovered a strong link between vitamin deficiencies and cognitive decline in older adults. The investigation, published in the journal 'Nutrients', surveyed over 184 individuals aged 55 to 85 years and found that 36.4% exhibited mild cognitive impairment (MCI).
The affected individuals displayed lower blood levels of several key micronutrients, with vitamin D, B1, B2, B6, B9, and B12 deficiencies being particularly prevalent among those with MCI. The study, titled 'Neuronal Biomarkers and Micronutrient Status in Adults with Mild Cognitive Impairment', also identified significant associations between blood levels of essential vitamins, neuronal biomarkers, and cognitive performance.
