Patients with mild cognitive impairment and mild to moderate Alzheimer's disease can provide information about their quality of life. This study determined whether aggregating patient and informant quality-of-life reports on the Cornell-Brown Scale for Quality of Life in Dementia can provide a broader perspective on the quality of life relative to patient or informant reports separately. Aggregated Cornell-Brown Scale for Quality of Life in Dementia scores were hypothesized to correlate more strongly with both patient and informant perspectives of patient's memory, function, and neuropsychiatric symptoms than the unaggregated measures. Results indicated that aggregated Cornell-Brown Scale for Quality of Life in Dementia scores reflected a blend of patient and informant perspectives on patient function. This study contributes to a growing line of research that recommends integrating patient and informant perspectives to achieve the most complete assessment of quality of life.
