2019 AUG 12 (NewsRx) -- By a News Reporter-Staff News Editor at Hospital & Nursing Home Daily -- Fresh data on Neurodegenerative Diseases and Conditions - Dementia are presented in a new report. According to news reporting out of Seoul, South Korea, by NewsRx editors, research stated, “This study aimed to examine the association between normal-but-low folate levels and cognitive function in the elderly population using a prospective cohort study. We analyzed 3,910 participants whose serum folate levels were within the normal reference range (1.5-16.9 ng/mL) at baseline evaluation in the population-based prospective cohort study named the ‘Korean Longitudinal Study on Cognitive Aging and Dementia.’ The association between baseline folate quartile categories and baseline cognitive disorders [mild cognitive impairment (MCI) or dementia] was examined using binary logistic regression analysis adjusting for confounding variables.”
Our news journalists obtained a quote from the research from Seoul National University Hospital, “The risks of incident MCI and dementia associated with the decline of serum folate level during a 4-year follow-up period were examined using multinomial logistic regression analysis. The lowest quartile group of serum folate (1.5, 5.9 ng/mL) showed a higher risk of cognitive disorders than did the highest quartile group at baseline evaluation (odds ratio 1.314, p=0.012). Over the 4 years of follow-up, the risk of incident dementia was 2.364 times higher among subjects whose serum folate levels declined from the 2nd-4th quartile group to the 1st quartile than among those for whom it did not (p=0.031). Normal-but-low serum folate levels were associated with the risk of cognitive disorders in the elderly population, and a decline to normal-but-low serum folate levels was associated with incident dementia.”
According to the news editors, the research concluded: “Maintaining serum folate concentration above 5.9 ng/mL may be beneficial for cognitive status.”
