Assessing Independence in Activities of Daily Living and Quality of Life in Patients with Dementia with Lewy Bodies

Abstract

Knowledge of performance in activities of daily living and quality of life is important for management decisions and research endpoints. The use of harmonized scales is essential for objective assessment of both caregivers and patients with dementia with Lewy bodies. Functionality and quality of life are more impaired in dementia with Lewy bodies than in Alzheimer’s disease, mostly due to higher prevalence of behavioral symptoms and motor manifestations in dementia with Lewy bodies. More longitudinal studies are required to assess if causality mediates the associations of clinical features with functional independence and worsened quality of life in these patients.
