Abstract Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS) presents a significant side-effect of CAR-T cell therapy, with cognitive dysfunction emerging as a core manifestation that can impact patient quality of life and their functional outcomes.To systematically review current evidence on the clinical impact, underlying mechanisms, assessment methodologies, and management strategies of ICANS-related cognitive dysfunction in CAR-T recipients.A systematic literature search was conducted across PubMed, EMBASE, Google Scholar and Web of Science databases following PRISMA guidelines. Studies reported ICANS affects 26.9% of CAR-T recipients overall, with cognitive dysfunction representing the most prevalent manifestation. Deficits in attention, memory, executive function, and language processing were consistently reported, with varying degrees of persistence ranging from days to months post-treatment.ICANS-related cognitive dysfunction represents a significant clinical concern requiring standardized assessment protocols and targeted interventions. Further research is needed to establish predictive biomarkers and effective management strategies.
