Mean values (±SE) of the clinical (i.e., Geriatric Depression Scale, Clinical Dementia Rating, and Hachinski Ischemic Score) genetic (i.e., Apolipoprotein E genotyping, APOE), and cerebrospinal fluid (i.e., beta amyloid 1-42, Aβ 42; protein tau, t-tau; and phosphorylated form of protein tau, p-tau) data as the results of their statistical comparisons (p < 0.05 corrected) in the groups of noADMCI-noEEA (N = 19) and noADMCI-EEA (N = 13) patients. The gene discussed is APOE; the disease is major depressive disorder.
