Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 65 and older with mild Alzheimer's Disease, as indicated by specific cognitive test scores.
✕Probably not a fit
Patients with other neurological or psychiatric disorders, gastrointestinal issues, or those who have recently used antibiotics or probiotics may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study investigates the effects of probiotics on patients with mild Alzheimer's Disease by comparing cognitive function and neuroinflammation levels between those receiving probiotics and a placebo group. Participants will undergo neuropsychological testing, blood tests for inflammatory markers, and assessments of their microbiome composition and dietary habits. The goal is to determine if probiotics can enhance cognitive performance and modify neurophysiological measures in this population.
Why it matters
Potential benefit: If successful, this could lead to new dietary interventions that improve cognitive function in patients with mild Alzheimer's Disease.
How similar studies have gone: While the use of probiotics in cognitive disorders is an emerging field, this specific approach in mild Alzheimer's Disease is relatively novel and has not been extensively tested.
