The subjects were divided into no\u2010to\u2010mild and moderate\u2010to\u2010severe groups according to the severity of NAFLD. The levels of peripheral blood cytokines and the scores of the Montreal cognitive assessment scale (MoCA) were measured for all subjects. The scale scores and cytokine levels were compared between the two groups, and the correlations among NAFLD, cytokines, and cognitive function were analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Compared with those in the no\u2010to\u2010mild group, the levels of IL\u20101\u03b2, IL\u20106, IL\u201010, and TNF\u2010\u03b1 in the moderate\u2010to\u2010severe group were significantly higher, while the MoCA score was significantly lower. Multivariate linear regression analysis indicated that the NAFLD grade could significantly affect the MoCA score and the levels of IL\u20101\u03b2 and TNF\u2010\u03b1. Mediation analysis revealed that the level of TNF\u2010\u03b1 significantly mediated the relationship between NAFLD and cognitive function, with a mediation effect size of 0.36.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Elevated TNF\u2010\u03b1 levels may be a key intermediate factor in the development of PSCI in patients with NAFLD.
