RESUMO
OBJECTIVE: To investigate the relationship between awareness of memory loss and psychological well-being in a nonclinically depressed sample of participants with mild to moderate Alzheimer disease (AD). METHODS: Study participants (N = 104) enrolled through Columbia University Medical Center and the University of Pennsylvania completed clinical and cognitive assessments. Participants were rated with regard to their degree of awareness of memory deficits and completed questionnaires relating to their psychological well-being, including mood and quality of life (QOL). Mediating models were used to establish the relationship between awareness, depression, and QOL and to examine potential mediators of awareness and depression, including psychological distress, objective memory deficits, and negative self-ratings. RESULTS: There was a direct association between awareness of memory deficits and depressed mood but not awareness and QOL. However, there was an indirect association between awareness and QOL through depression. Neither psychological distress, memory deficits, nor negative self-ratings mediated the relationship between awareness and depression. CONCLUSION: Awareness is associated with depressed mood in nonclinically depressed participants with mild to moderate AD. However, depressed mood does not appear to reflect the direct psychological reaction to awareness of memory loss. Moreover, awareness has only an indirect association with QOL via depressed mood. These results suggest that preserved awareness does not have a direct negative impact on overall psychological well-being in AD.
