Abstract  Studying the EEG characteristics in mild cognitive impairment (MCI) of diabetes is helpful to the early prevention and diagnosis of the disease. Based on the multi-scale recurrence plot. We analyzed the deterministic characteristics of 15-electrode eye-closed resting state EEG of 14 patients with mild diabetes mellitus MCI(DM-MCI) and 11 patients with normal cognitive function of diabetes mellitus(DM-nMCI), and 16 patients with mild cognitive impairment without diabetes mellitus(nDM-MCI) and 10 patients with normal cognitive function without diabetes mellitus (nDM-nMCI). Deterministic values between the four groups were statistically analyzed using one-way ANOVA, and the correlations between deterministic values and cognitive function of each electrode were calculated by Pearson correlation method. The results showed that at small scale1≤s≤4, the values of DET in patients with nDM-MCI and nDM-nMCI were significantly higher than those with DM-MCI and DM-nMCI; At large scale12≤s≤15, four groups of DET values tend to be consistent. The deterministic values of all electrodes at different scales in the DM-MCI group were higher DM-nMCI group. The deterministic values of MCI at C3 (DM-MCI: 0.83±0.09, nDM-MCI: 0.86±0.09) and C4(DM-MCI: 0.85±0.08, nDM-MCI: 0.88±0.08) electrodes increased significantly at different scales, which were important characteristics in distinguishing MCI and their correlations between DET and neuropsychological test scores Boston (P=0.033), FAQ (P=0.026), WAIS (P=0.037), and MoCA (P=0.039, P=0.017) was significant. The DET values of Fp1 (DM-MCI: 0.80±0.09, DM-nMCI: 0.75±0.07), Fp2(DM-MCI: 0.80±0.09, DM-nMCI: 0.75±0.01) and Oz (DM-MCI: 0.76±0.06, DM-nMCI: 0.73±0.07) at small scale, and Fp2 (DM-MCI: 0.96±0.03, DM-nMCI: 0.94±0.01) at big scale increased significantly, which are the important characteristics in distinguishing DM. It was suggested that the determinacy based on multi-scale order recurrence plot was the EEG feature associated with cognitive decline and DM.
