We assessed the influence of race and education on informants’ reports of cognitive decline in 252 community-residing older persons who were receiving services from senior health agencies. An expert consensus panel made diagnoses of normal cognition, cognitive impairment no dementia (CIND), and dementia based on clinical evaluations and standardized neuropsychological testing (using both population and race-adjusted norms). Informants were interviewed using the Informant Questionnaire for Cognitive Decline in the Elderly (IQCODE).

An analysis of covariance which controlled…
