Mean ± standard deviation (SD) and p-values. The p-values were obtained by two-independent samples t-test (∗) or chi-square test (∗∗) where relevant. M, male; F, female; MMSE, Mini Mental State Examination score; RH_ICV and LH_ICV, right and left hippocampal volume normalized with intracranial volume, respectively. Highest education completed, using five levels: (1) Illiterate, (2) Primary studies, (3) Elemental studies, (4) High school studies, and (5) University studies.
