Objective: The present study aimed to investigate the relationship among neurocognitive variables, depressive symptoms, functional activities, and the quality of life (QoL) in patients with mild dementia and single-domain amnestic mild cognitive impairment (a-MCI). Materials and Methods: Thirty-seven mild dementia patients and thirty a-MCI participants were recruited. All subjects participated in a series of neuropsychological measures (Cognitive Abilities Screening Instrument, family pictures, and digit span), geriatric depression scale-15 (GDS-15), activities of daily living (ADL), The Lawton instrumental ADL scale (IADL) and QoL-Alzheimer's disease. Results: Multiple regression analysis revealed that only depressive symptoms was a predictor for the QoL in mild dementia (β = −0.56, P < 0.001). In contrast, all variables were not associated with the QoL in a-MCI. Mildly demented people scored significantly lower on most aspects of cognitive functioning and reported poorer performances on IADL than a-MCI. There were no significant differences on GDS, ADL, and QoL between the two groups. Conclusion: Findings indicated that depressive symptoms contributed to the QoL in mild dementia. Interventions targeting depressive symptoms in mild dementia may improve their QoL during their early stages of dementia.
