Summary
The objective of this study was to identify neural correlates of cognitive improvement after 3 months of donepezil hydrochloride treatment using either or both of two functional magnetic resonance imaging (fMRI) measures - the functional Hippocampus Connectivity Index (HCI) and Cerebral Blood Flow (CBF) Perfusion; in the Medial Temporal Lobe (MTL) network in subjects in the early stage of Alzheimer's Disease (AD).
