Vitamin D is said to be one of the most important nutrients for our body as it helps in reducing the risk of heart disease, multiple sclerosis and even rheumatoid arthritis. A new study has found that the deficiency of Vitamin D could increase the risk of developing dementia, according to express.co.uk.
In a study, earlier this year, Austrian researchers said people with more exposure to sunlight, a major source of Vitamin D, had a lower risk of dementia. About 8,50,000 people in the UK have dementia. In India, this number is much higher with 4.1 million people having dementia and almost 47 million people living with dementia around the world. In 2014, a research claimed patients with a deficiency of Vitamin D were “substantially” more at risk of developing the condition.
Adults, who were moderately deficient in the vitamin had a 53% higher risk of getting dementia, while those who were severely deficient were 122% more likely to develop the condition. The research followed more than 1,600 people for six years to investigate who developed Alzheimer’s disease, as well as other forms of dementia.
Dr David Llewellyn, a researcher working on the study, said, “We expected to find an association between low Vitamin D levels and the risk of dementia and Alzheimer’s disease, but the results were surprising. We actually found that the association was twice as strong as we anticipated. Clinical trials are now needed to establish whether eating foods such as oily fish or taking Vitamin D supplements can delay or even prevent the onset of Alzheimer’s disease and dementia.”
More studies were needed to confirm the link between dementia and Vitamin D, but the scientists said the findings were very promising and encouraging.
Llewellyn noted, “Even if a small number of people could benefit, this would have enormous public health implications given the devastating and costly nature of dementia.”
