Relative importance of patient disease indicators on informal care and caregiver burden in Alzheimer's disease

Abstract

For patients residing in community dwellings, the direct influence of patients' cognition on caregiver burden is limited and rather mediated by other disease indicators. Instead, the patients' ADL-abilities are the main predictor of informal care hours, and both ADL-abilities and behavioral disturbances are important predictors of perceived caregiver burden, where the latter has the strongest effect. These results were consistent across Sweden, U.K. and the U.S.A.
