Researchers have found that subtle changes in blood metabolites, produced by gut bacteria, may signal the earliest signs of cognitive decline years before symptoms appear. This insight comes from a study published in Gut Microbes by scientists at the University of East Anglia, who analyzed blood and stool samples from 150 adults aged 50 and … Weiterlesen …
New blood test predicts dementia years before symptoms appear A breakthrough in dementia screening now analyzes 33 microbial metabolites in blood samples, achieving 79 percent accuracy in predicting cognitive decline years in advance, with just six key metabolites delivering over 80 percent precision. Key Insight The gut-brain axis has emerged as a critical frontier in … Weiterlesen …
German researchers have identified a specific gut bacterium that undermines memory and muscle strength in aging by disrupting vagus nerve signaling, offering a potential explanation for why some people remain cognitively sharp into their 100s while others decline decades earlier. The bacterium Parabacteroides goldsteinii accumulates in the intestines of older individuals and triggers a cascade … Weiterlesen …
