Probiotics in Mild Alzheimer's Disease

This trial is testing whether a daily probiotic capsule can reduce brain inflammation, improve thinking and memory, and change brain activity patterns in people who already have mild Alzheimer's disease. It compares the probiotic group to a placebo group. This is an Early Phase 1 trial, meaning it is a very early-stage safety and feasibility test — far from proven or approved.
