Summary

Story summary

Future probiotic research should include longitudinal studies to assess long-term cognitive effects.
Durations range 6–12 weeks and dosages from 1 × 10^9 to 1.8 × 10^10 colony-forming units (CFU).
Older adults show cognitive benefits, especially memory and executive function, possibly via gut microbiota changes.
Language gains in young adults and executive function in children require longer interventions, with demographic gaps.
