Most gut – brain axis studies have focused on serious brain diseases such as Alzheimer’s, Parkinson’s and dementia. Very limited research has been conducted related to cognitive decline through aging. Age-related cognitive decline is inevitable for all of us.

 

Scientists decided to study the impact of gut health and aging as reported in SciTech Daily (article link below). University of North Carolina at Chapel Hill and North Carolina State University researchers examined cognitive scores of study participants and found they experienced improvement from mild cognitive impairment after receiving the probiotic Lactobacillus rhamnosus GG(LGG) for a three-month period (reported in the August 2023 issue of Science Tech Daily). Likewise, the report sighted that a decrease in abundance of Prevotella bacteria correlated with improved cognitive scores.

 

Mashael Aljumaah who is affiliated with both aforementioned universities and King Saud University in Saudi Arabia, says it “opens up new avenues for combating cognitive decline associated with aging,” as quoted in Science Daily.
