Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main objective is to investigate whether administration of probiotics to patients with mild Alzheimer's Disease (AD) reduces neuroinflammation, improves cognitive function and modifies neurophysiological measures, compared to a patient group that receives placebo (no active probiotics).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

We will measure specific blood inflammatory markers (primary outcome), neurophysiological activity, cognitive test scores, microbiome composition and dietary habits of participants in the probiotics and placebo group.
