Abstract: The purpose of this article is to analyse the available literature describing the economic burden of
dementia and to compare costs between studies examining cost drivers. To shed light on this
field, a systematic review is performed using PubMed, the Cochrane Library and Web of Science.
An eight-year retrospective horizon was considered until 25 May 2018. Several papers were
obtained from the database search (n ¼ 23), being others (n ¼ 3) identified through other sources
(hand-searching) because we did not detect it through the three databases. The cost estimates
were compared between three perspectives: state/publicly funded health services, third-party/
private sector/not-for-profit organisations and patient and family and/or societal. The estimated
total annual cost per person with dementia in Europe is on average e32,506.73 (n ¼ 10), whereas
for the United States, it gets e42,898.65 (n ¼ 2). Furthermore, differences are appreciated by
type of costs. Besides, differences by severity groups are also considered. Overall, the higher the
severity the higher the associated costs. Dementia imposes a huge economic burden. The figures
here presented provide a good framework to quantify these costs for both, economic experts
and researchers, and policy decision makers.
