| Annotation | Few studies have examined whether individuals with Mild Cognitive Impairment (MCI) tend to underestimate their deficits. In this study, the authors examined whether the degree of discrepancy between patient and informant reported everyday functioning was associated with cognitive status. The sample consisted of 111 ethnically diverse community-dwelling older people (46 Caucasian and 65 Hispanic) which was divided into four diagnostic categories: cognitively normal, MCI memory impaired, MCI non-memory impaired, and demented. Everyday functional abilities were measured using both a self-report and informant report version of the Daily Function Questionnaire (DFQ). A Difference Score was calculated by subtracting patients' DFQ score from their informants' score. DFQ Difference Scores were significantly higher in the demented group compared to normal and both of the MCI groups. However, the Difference Scores for the MCI groups were not significantly different than the normals. Further, while patient reported everyday functioning did not differ among the four diagnostic groups, informant reported functional status was significantly different across all diagnostic groups except MCI non-memory vs normals. Performance on objective memory testing was associated with informant-rated but not patient-rated functional status. Demographic characteristics of patients and informants, including ethnicity, had no association with the degree of discrepancy between raters. Although there may be some mild functional changes associated particularly with the MCI memory impaired subtype, individuals with MCI do not appear to under-report their functional status as can often be seen in those with dementia.
