Semantic Memory Impairment for Biological and Man-Made Objects in Individuals With Amnestic Mild Cognitive Impairment or Late-Life Depression

摘要

Objective: Amnestic mild cognitive impairment (aMCI) and late-life depression (LLD) both increase the risk of developing Alzheimer disease (AD). Very little is known about the similarities and differences between these syndromes. The present study addresses this issue by examining the nature of semantic memory impairment (more precisely, object-based knowledge) in patients at risk of developing AD.
