Recent evidence links POD to mitochondrial dysfunction. While intermittent fasting (IF) has been shown to enhance mitochondrial function and exert neuroprotective effects, potentially through gut microbiota modulation, its ability to prevent POD and the underlying mechanisms remain unclear.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We examined the effects of preoperative IF on delirium\u2010like behavior in aged mice following anesthesia\/surgery. Assessments included neurobehavioral tests, gut microbiota composition, fecal shortchain fatty acids (SCFAs), hippocampal synaptic and mitochondrial ultrastructure via transmission electron microscopy, mitochondrial function, and related molecular markers. To establish causality, fecal microbiota transplantation and SCFA supplementation experiments were conducted.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Preoperative IF significantly attenuated anesthesia\/surgery\u2010induced delirium\u2010like behaviors. Mechanistically, IF reshaped the gut microbiota and preserved SCFA levels, which collectively maintained hippocampal mitochondrial homeostasis. Both fecal microbiota transplantation and SCFA supplementation replicated the protective effects of IF, confirming the causal role of gut microbiota and its metabolites.<\/jats:p>\n
