An Indian-American scientist in the US has come up with a probiotic drink that may guard against dementia, a brain ailment that impacts over 57 million individuals worldwide. The new combination, devised by Dr. Hariyom Yadav at the University of South Florida, is intended to nourish the gut microbiome, which experts are increasingly connecting to mental wellness.
How the gut and brain are linked.
The gut harbors trillions of microbes, good and bad. In a healthy person, this intricate system operates in harmony. However, when pathogenic bacteria or viruses become dominant, it may result in mass inflammation and systemic issues, including cognitive impairment.
Testing the Brain-Boosting Cocktail
To try out their formula, the researchers fed the probiotic cocktail to mice in their drinking water for 16 weeks. Then the mice received a "water maze" test to assess their spatial learning and memory. The probiotic-fed mice searched for the hidden platform more quickly and consistently than did the mice given no probiotics.
More Than Just Memory Boosting
Aside from maze performance, treated mice exhibited biological indicators of protection. The cocktail decreased detrimental proteins associated with the creation of Alzheimer’s associated brain plaques. It seemed to decrease inflammation in the brain and preserve the integrity of the blood-brain barrier, which acts as a protective buffer that keeps dangerous substances from entering the brain.
Power in Probiotic Synergy
What differentiates this probiotic is its blend of multiple strains, a different approach than what is traditionally used.
“Normally, people look at some single-strand probiotics. But we discovered that when they are put together as a consortia, they actually have more power for manipulating microbiomes, switching them from the bad side to the good side,” Yadav said.
The cocktail achieves this by inhibiting inflammatory bacteria within the gut, allowing for a more hospitable environment for good microbes to grow.
What's next for the brain-enhancing compound?
With promising clinical outcomes, Dr. Yadav's team is now pursuing commercial collaborations to take this innovation to the market. The goal is to provide a noninvasive, gut-based solution for lowering the risk of dementia and Alzheimer's disease in humans.
