AD subjects were scanned at baseline and after donepezil treatment. CN subjects were scanned only at baseline as a reference to identify regions correlated or anticorrelated to the hippocampus. Before each scan, participants underwent cognitive, behavioral, and functional assessments.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>After donepezil treatment, neural correlates of cognitive improvement measured by Mini\u2010Mental State Examination scores were identified in the left parahippocampus, dorsolateral prefrontal cortex (DLPFC), and inferior frontal gyrus.
