The aim of this thesis is to study what Dementia is costing the society in Sweden year 2020 and how the relationship between specialized care costs and outside sources relates to each other. In this study we use the economic model from Jo (2014) and the Two-Part model by Sauzet et al (2019). A binary logistic regression attempts to examine a potential relationship between specialized care costs and outside sources. We use the human capital approach to shed light on total care costs for Dementia and establish a Cost of Illness study. The results show an estimation that Dementia costed Sweden 68,5 billion SEK in 2020 and the regression establishes that there is a relationship between specialized costs and outside sources, for example age affecting the cost of being a dementia patient more than where you live.
