What's Happening?
A systematic review has been conducted to assess the effects of oral probiotic interventions on brain structure and function in human adults. The review included 19 studies with a total of 762 participants,
examining the impact of various probiotic strains on brain connectivity, morphometry, and functional outcomes. The studies varied in their methodologies, including the types of probiotics used, the duration of interventions, and the health conditions of participants. Some studies reported changes in brain connectivity and structure, while others found no significant effects. The review highlights the complexity of probiotic effects on the brain, suggesting that outcomes may depend on specific strains, dosages, and individual health conditions.
Why It's Important?
This review is important as it explores the potential of probiotics to influence brain health, a growing area of interest in both scientific and consumer health communities. Probiotics are often marketed for their gut health benefits, but their impact on brain function could open new avenues for treating neurological and psychological conditions. Understanding the specific conditions under which probiotics affect brain health could lead to targeted therapies for conditions like depression, anxiety, and cognitive decline. However, the variability in study results also indicates the need for more standardized research to determine the most effective probiotic strains and dosages.
