Registry summary
The goal of this pilot study is to explore a combination of two interventions: (1) a behavioral alcohol-reduction intervention using motivational interviewing, and (2) a blinded probiotic microbiome or placebo intervention. The study examines whether these interventions improve cognitive and neurophysiological function, including brain metabolism, in older adults who are high-risk alcohol drinkers.
