Evidence of Subtle Gray-Matter Pathologic Changes in Healthy Elderly Individuals With Nonspecific White-Matter Hyperintensities

Abstract
NONSPECIFIC white-matter hyperintensities (WMHs) are frequently seen on conventional magnetic resonance (MR) images of the brain from elderly individuals.1-3 Although the nature and clinical significance of WMHs in the elderly are still unclear, the most plausible pathological substrate for such changes is thought to be ischemic damage.4,5
