Hemispheric differences in hippocampal volume predict verbal and spatial memory performance in patients with Alzheimer's disease

Atrophy of the hippocampal formation, a region important for the acquisition of new declarative knowledge, has been well-documented in Alzheimer's disease (AD), although the relation of such atrophy to the extent of memory dysfunction in these patients has been less clear. In the present study, 18 patients with a clinical diagnosis of probable AD were studied with a high-resolution, quantitative magnetic resonance imaging (MRI) protocol, as well...
