Demographic variables including gender, age, mini-mental state examination (MMSE) scores and education scores. Education level is quantified as: 1. Illiterate; 2. Elementary school studies; 3. Secondary school studies; 4. Technical or Mid-level studies; 5. Higher-education or University studies. Data are given as mean (standard deviation). 1p < 0.01 significant difference after paired t-test statistical evaluation in comparison between HC and sdMCI. 2p < 0.01 significant difference after paired t-test statistical evaluation in comparison between HC and mdMCI.
