Researchers at Kyushu University Target Alzheimer Disease (Association Between Serum b-alanine and Risk of Dementia: the Hisayama Study)
Mental Health News Daily
2019 JUN 11 (NewsRx) -- By a News Reporter-Staff News Editor at Mental Health News Daily -- New research on Neurodegenerative Diseases and Conditions - Alzheimer Disease is the subject of a report. According to news reporting out of Fukuoka, Japan, by NewsRx editors, research stated, “The aim of this study was to examine the association between serum concentrations of b-alanine, a metabolite from carnosine and anserine, and the risk of dementia in a general elderly population of Japanese. In 2007, 1,475 residents of Hisayama, Japan aged 60-79 years without dementia were divided into four groups according to the quartiles of serum b-alanine concentrations (Q1, lowest; Q4, highest) and followed up for 5.3 years (median).”
Our news journalists obtained a quote from the research from Kyushu University, “During the follow-up, 117 subjects developed all-cause dementia (Alzheimer’s in 77 cases and vascular dementia in 31). The risk of all-cause dementia decreased with elevating serum b-alanine levels after adjustment for potential confounding factors (hazard ratio [95% confidence interval]: Q1, 1.00 [reference]; Q2, 0.73 [0.45, 1.18]; Q3, 0.50 [0.28, 0.89]; Q4, 0.50 [0.27, 0.92]; p=0.01 for trend). A similar inverse association was observed for Alzheimer’s disease (Q1, 1.00 [reference]; Q2, 0.78 [0.44, 1.38]; Q3, 0.53 [0.26, 1.06]; Q4, 0.53 [0.25, 1.10]; p=0.04 for trend), but not for vascular dementia.”
According to the news editors, the research concluded: “Higher serum b-alanine levels were significantly associated with lower risks of all-cause dementia and Alzheimer’s disease. Since serum b-alanine levels reflect the intakes of carnosine/anserine, higher intakes of carnosine/anserine may be beneficial for the prevention of dementia.”
