The Gut-Brain Axis and Academic Performance: A Multidisciplinary Review of Mechanisms, Disruptions, and Evidence-Based Interventions”

The gut-brain axis (GBA) is a bidirectional communication system linking the central nervous system, enteric nervous system, endocrine and immune pathways, and the gut microbiota. Recent advances show that this axis plays a crucial role in regulating cognition, mood, and neuroplasticity, with growing implications for learning and academic performance. Dysregulation of the GBA through poor diet, stress, sleep deprivation or environmental toxins has been associated with systemic inflammation, metabolic dysfunction, and mental health challenges that compromise educational outcomes. Conversely, interventions such as probiotics, prebiotics, dietary fiber, exercise, and stress management have shown promise in improving emotional resilience and cognitive capacity. This review synthesizes recent findings on the mechanisms of GBA signaling, factors that disrupt its balance, and strategies to optimize gut health in ways that may enhance student well-being and performance. While preliminary evidence is encouraging, further longitudinal and interventional studies are needed to establish causal links and develop practical applications in educational settings.
