Brief Summary
This pilot randomized, double-blind, crossover clinical trial will evaluate the effect of a synbiotic containing Lactobacillus acidophilus LA-5 and agave inulin on mild cognitive impairment (MCI) in adults aged 60-75 years attending the Defense Medical Specialties Unit. Forty participants with MCI will be randomized into two groups of 20 participants. The intervention will consist of daily administration of L. acidophilus LA-5 (4 × 10⁹ CFU), 7 g of agave inulin, and almond powder for 12 weeks, while the control group will receive almond powder as the vehicle. After a two-week washout period, participants will cross over to the alternate intervention for an additional 12 weeks. Cognitive function will be assessed using the Montreal Cognitive Assessment (MoCA), Memory Alteration Test (M@T), and Mini-Mental State Examination (MMSE). Secondary assessments will explore potential mechanisms of the microbiota-gut-brain axis by measuring fecal L. acidophilus LA-5 and butyrate, as well as serum BDNF and inflammatory biomarkers including IL-1β, IL-6, IL-10, and TNF-α. The study aims to determine whether synbiotic supplementation improves cognitive performance in older adults with MCI and whether these changes are accompanied by modifications in gut microbial activity, short-chain fatty acid production, neurotrophic signaling, and systemic inflammation.
