ICMR Study Links Micronutrient Deficiencies to Dementia Risk in Ageing Indian Adults

A new study conducted by the Indian Council of Medical Research-National Institute of Nutrition (ICMR-NIN) has found that deficiencies in key vitamins and micronutrients may be associated with a higher risk of dementia among Indian adults. The findings underscore the importance of nutrition in maintaining brain health and suggest that dietary improvements could play a role in reducing the risk of cognitive decline as India's population continues to age.

The study examined 570 adults between the ages of 40 and 80 from both rural and urban areas of Telangana. Researchers identified multiple micronutrient deficiencies among participants who showed a higher predicted risk of dementia and cognitive impairment. The findings add to a growing body of evidence indicating that nutritional status may significantly influence long-term brain function, memory, and overall cognitive performance.

According to experts, while genetics can contribute to dementia risk, nearly half of all dementia cases may be linked to modifiable factors. These include conditions such as high blood pressure, diabetes, physical inactivity, depression, social isolation, and poor nutrition. Micronutrients, including essential vitamins and minerals, are known to support nerve function, brain development, and memory processes. Deficiencies in these nutrients may lead to inflammation, impaired neural communication, and other biological changes associated with cognitive decline.

Researchers noted that diets rich in fruits, vegetables, whole grains, and other nutrient-dense foods may help lower the burden of dementia-related risk factors. The study highlights the need for greater awareness of nutritional health and preventive measures aimed at improving dietary habits. As dementia cases are projected to rise globally, the findings reinforce the importance of addressing nutrition as a potentially manageable factor in preserving cognitive health and reducing the risk of age-related neurological disorders.
