The Effect of Probiotic Supplementation on Cognitive and Emotional Functions in Healthy Elderly Subjects
The Effect of Probiotic Supplementation on Cognitive and Emotional Functions in Healthy Elderly Subjects: a Randomized, Double-blind, Cross-over and Controlled Trial
연구 개요
상세 설명
Gut microbiota (GM) has focused as an important target for emotional and cognitive diseases, moreover in a population that show an altered GM such as elderly population as age-related changes. Several studies have shown that ageing alter GM, both in diversity and integrity.
Probiotics have demonstrated that correct or prevent age-related dysbiosis, in order to reduce or prevent intestinal permeability and associated inflammation, inhibit the generation of harmful and/or toxic metabolites, as well as promote the production of beneficial bacterial components.
The aim of this study is to assess the effectiveness of a multiprobiotic formulation as a therapeutic strategy to attenuate the emotional and cognitive decline associated with ageing in healthy adults over 55 years of age. The hypothesis is that administration of a multi-species probiotic for 10 weeks will slow and/or ameliorate the decline in emotional and cognitive function inherent to senescence.
