Older people who start taking vitamin D before memory loss may be less likely to develop dementia, says a new study. The study, published in Alzheimer’s and Dementia, the journal of the Alzheimer’s Association, found that the higher the vitamin D levels in all four of her brain regions in the individuals tested, the more likely she was to develop dementia or mild cognitive impairment. was found to decrease by 25-33% of This study is important because it shows for the first time how vitamin D is involved in cell signaling pathways that may be part of the neurodegenerative process.
Indian experts say that although the sample size of the study was small, these are important findings and require further research studies. I warn you not to take it.
This study suggests that nutritional strategies play an important role in delaying or preventing the onset of cognitive decline and dementia, either by directly affecting neuropathology or by promoting resilience to pathology. One nutritional factor that has received considerable attention is vitamin D, an essential fat-soluble vitamin and prohormone obtained through diet and exposure to sunlight. said the researchers. Dr. Rajas Deshpande, Director of Neurology at Jupiter Hospital, Pune, said the results are significant, despite the small sample size, as they show less degeneration in the brain due to higher levels of vitamin D. I said yes. Advances and research in the field of dementia have led to many ways to prevent early dementia, such as including certain foods and walnuts in your diet, taking vitamin D supplements, and taking more steps. shown. However, it is not advisable to start taking high-dose vitamin D supplements on your own without consulting your doctor, as toxic levels can lead to heart arrhythmias. However, “a causal link between vitamin D and dementia needs to be established,” he added.
Dr. Anil Venkitachalam, Consultant Neurologist at Kokilaben Hospital, Navi Mumbai, said vitamin D is associated with many neurological disorders. “Studies have clearly demonstrated the role of vitamin D in multiple sclerosis. There is also some evidence linking low vitamin D levels to stroke. The cause-and-effect relationship is unknown, but the fact remains that vitamin D has neuroprotective effects and that adequate levels of it may slow neurodegeneration and prevent nerve damage.

Dementia is a general term for a group of progressive neurodegenerative brain disorders that occur in older people. Alzheimer’s disease is one of the specific causes of dementia. By 2050, the global prevalence of dementia is projected to exceed 150 million he, which is six times higher than it was in 2019. Therefore, with an aging population, there is an urgent need for preventive strategies to reduce the burden of Alzheimer’s disease (AD) and dementia. M Kyla Shea, Principal Investigator, USDA Human Nutrition Research Center on Aging, Tufts University, Boston, Massachusetts, said: According to 2020 estimates, her 5.3 million Indians over the age of 60 had dementia. However, this may be a conservative estimate. What is alarming, however, is that this number is expected to triple her figure over the next 30 years. Moreover, India’s geriatric population is growing rapidly, with reports predicting that by 2050, almost one-fifth of the total population will be over the age of 60.
