At baseline, T2DM-associated sphingolipids (ceramide C22\u200a:\u200a0, monohexylceramide C16\u200a:\u200a1, and lactosylceramide C24\u200a:\u200a0) were associated with poorer memory, attention, and psychomotor processing speed performance. Among 50 completers, an indirect effect of T2DM on less improvement in verbal memory was mediated by monohexylceramide C16\u200a:\u200a1 (0.86 fewer words recalled, 95% bootstrap confidence interval [\u20132.32, \u20130.24]), and an indirect effect of T2DM on less visuospatial memory improvement was mediated by ceramide C22\u200a:\u200a0 concentrations (0.42 fewer points, 95% bootstrap confidence
