Pediatric Sepsis-Associated Encephalopathy (SAE) poses a critical challenge in the management of septic children, presenting a spectrum of neurological dysfunctions within the context of sepsis. This comprehensive review aims to elucidate the multifaceted aspects of SAE, exploring its pathophysiological mechanisms, diverse clinical manifestations, diagnostic intricacies, treatment modalities, prognostic indicators, and long-term neurodevelopmental outcomes. SAE emerges as a consequence of systemic inflammation, leading to neuronal injury, neuroinflammation, and cerebral dysfunction. Clinical manifestations vary widely, encompassing altered mental status, focal neurological deficits, and autonomic dysregulation, complicating timely diagnosis. While supportive care targeting sepsis management remains fundamental, therapeutic approaches addressing cerebral dysfunction in SAE are evolving. Long-term outcomes exhibit significant variability, emphasizing the need for individualized prognostication and comprehensive follow-up strategies. Future research directions encompass precision medicine approaches, biomarker discovery, innovative therapeutics, advanced neuroimaging techniques, and ethical considerations, highlighting avenues for advancing SAE management and improving outcomes in septic pediatric patients.
