Source: own calculations based on published sources (Wang et al., 2008, Mould-Quevedo et al., 2013, Wimo et al., 2010). NB: PADL — personal activities of daily living; IADL — instrumental activities of daily living. Non-care medical costs consist of AD-related outpatient costs, inpatient costs, medication costs and physical therapy costs, non-care non-medical costs include transportation and special equipment .
