Memory self-report in Alzheimer's disease and in age-associated memory impairment.
We investigated memory self-report in Alzheimer's disease (AD) and age-associated memory impairment (AAMI). AD and AAMI patients and healthy elderly subjects were administered a self-report memory questionnaire, memory tests, a family-rated memory questionnaire, and a depression scale. The AD group reported worse memory than the control group, but many individual AD subjects reported normal memory. This finding confirms clinical observations that unawareness of memory loss is common in AD but variable across patients. Multiple regression analysis revealed that worse memory self-ratings were associated with greater dementia severity and higher depression scores. In the AAMI group, memory self-ratings were predicted by family ratings of memory ability but not by memory test scores. There was a nonsignificant trend for depression scores to predict memory self-ratings. Finally, level of self-reported memory ability did not differ for AD and AAMI, contradicting clinical lore that memory complaint is a useful diagnostic indicator.
