Microbiome Could Play Role in Preventing Cognitive Decline

A new study published in Nature Communications suggests that a daily fiber supplement could improve brain function in older adults. Researchers found that in just 12 weeks, participants who took the supplement showed better performance in memory tests that are often used to detect early signs of Alzheimer’s disease. This placebo-controlled, double-blind trial was conducted on twins over the age of 65, offering insight into how gut microbiome interventions could benefit cognitive health in older adults.
