The inverse\u2010variance weighted (IVW) method was utilized to estimate causal effects, supported by MR\u2010CAUSE and other sensitivity analyses to address pleiotropy and heterogeneity. Instrumental variables from genome\u2010wide association studies were applied, and initial associations were examined using linkage disequilibrium score (LDSC) regression analysis. Furthermore, mediation analysis was conducted to identify potential mediators.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    The MR analysis revealed significant positive associations between NAFLD occurrence and major depression (odds ratio [OR]\u2009=\u20091.294,\n                    <jats:italic>p<\/jats:italic>\n                    = 0.003), bipolar disorder (OR\u2009=\u20090.895,\n                    <jats:italic>p<\/jats:italic>\n                    = 0.004), and autism (OR\u2009=\u20091.118,\n                    <jats:italic>p<\/jats:italic>\n                    = 0.005). However, only the putative causal association of major depression on NAFLD remained statistically significant in further validation, including MR\u2010CAUSE and sensitivity analyses, and was not attributable to linkage disequilibrium. No causal effect of NAFLD on mental disorders was found in reverse MR analysis. In LDSC regression, significant positive associations with NAFLD occurrence were observed for major depression (Rg\u2009=\u20090.538,\n                    <jats:italic>p<\/jats:italic>\n                    = 1.36\n                    <jats:italic>E<\/jats:italic>\n                    \u2212 07), ADHD (Rg\u2009=\u20090.798,\n                    <jats:italic>p<\/jats:italic>\n                    = 1.10\n                    <jats:italic>E<\/jats:italic>\n                    \u2212 08), and PTSD (Rg\u2009=\u20090.579,\n                    <jats:italic>p<\/jats:italic>\n                    = 0.009).
