Correlation results between cortical thickness of eight neocortical ROIs and total hippocampal volume in only AD individuals (n = 163).

Spearman's rank correlation coefficients listed with p-values in parentheses. All analyses included age, gender, education, and APOE-ε4 carrier status as co-variates. HV = Hippocampal volume, CMF = Caudal portion of middle frontal gyrus thickness, ERC = Entorhinal cortex thickness, IPL = Inferior parietal lobule thickness, ITG = Inferior temporal gyrus thickness, ISC = Isthmus portion of cingulate cortex thickness, LOC = Lateral portion of occipital cortex thickness, MOF = Medial portion of orbital frontal cortex thickness, TPC = Temporal pole thickness, NS = Not significant.
