The predictor variables comprised age, APOE ε4, sex, years of education, Body Mass Index (BMI), history of hypertension, history of alcohol abuse, history of smoking behavior, history of cardiovascular events, Cerebrospinal fluid (CSF) of tau and Amyloid β (Aβ), volumes measured from brain magnetic resonance imaging (sum of left and right hippocampal volumes, sum of left and right ventricle volumes, intracranial volume, fluorodeoxy-glucose-positron emission tomography (FDG-PET)), and Mini Mental State Exam score (MMSE)
