P < 0.001. A p-value of less than 0.05 was considered statistically significant and the corresponding results are shown in bold. MRI volumetric data are given in cubic centimeters.

Using Pearson’s correlation (r) for continuous variables, and t-test for categorical variables. FCSRT-IR = Buschke and Grober Free and Cued Selective Reminding Test–Immediate Recall; HV = hippocampal volume; TBV = total brain volume; TICV = total intracranial volume; LM-I= logical memory immediate subtest, and LM-=logical memory delayed subtest.
