This study aims to assess whether there are differences between the level of awareness in early-onset Alzheimer disease (EOAD) and late-onset Alzheimer disease (LOAD) and to test its association with quality of life (QOL). A consecutive series of 207 people with Alzheimer disease and their caregivers were selected from an outpatient unit. There were no significant differences in awareness. In LOAD, impairment on awareness was predicted by functional level (β = .37, P < .001), self (P = .006), and informant report of QOL (P = .010). The predictors of unawareness in EOAD were self (P = .002) and informant report of QOL (P < .001). There is a specific profile of functional deficits underlying awareness in people with LOAD. Additionally, reports of EOAD QOL were more strongly related to awareness than in people with LOAD.
