₁ H‐MRS, MRI‐Based Hippocampal Volumetry, and ^99m Tc‐HMPAO‐SPECT in Normal Aging, Age‐Associated Memory Impairment, and Probable Alzheimer's Disease

Abstract

These findings support the hypothesis of a continuum among the three conditions studied, or at least between AAMI and DAT, where AAMI seems to be an early, monosymptomatic stage of Alzheimer disease. Accepting this view, it would be questionable to maintain the term "age-associated memory impairment" as a discrete entity.
