Summary

This pilot study tests whether a combination of reducing alcohol and taking a probiotic supplement can improve thinking skills and brain metabolism in healthy older adults (ages 65-84) who are heavy drinkers. Twenty participants will receive either a probiotic or a placebo for 30 days, plus a single counseling session to help cut back on drinking. Researchers will measure changes in cognitive test scores and brain glucose levels.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Probiotic supplement (Visbiome) and behavioral counseling (motivational interviewing)
What this could lead to: If it works, this could point toward a simple way to protect brain function in older adults who drink heavily.
What could go wrong: This is a very small pilot study with only 20 people, so results may not apply widely. The combination approach makes it hard to know which part helps.
