Abstract: Background:The World Health Organization has estimated that worldwide around 50 million people have dementia. The World Alzheimer Report estimated that between 2 and 10% of all cases of dementia begin before the age of 65. Early and young onset dementias (EYOD) provoke more working, social, family, and economic consequences than late onset dementias. All general studies about costs of dementias show that most of them are indirect or social costs. Despite that, very few studies have been performed in EYOD. Objective:To do a systematic review of literature about indirect or social costs in EYOD to know the state of knowledge and to discover gaps that should be filled. Methods:A systematic review was performed in the main database: Scopus, PsychInfo, Web of Science (Web of Science Core Collection, Medline and SciELO), and CINAHL. Additionally, we looked for reviews in Cochrane and in the International Prospective Register Of Systematic Reviews (PROSPERO). Results:Most of the studies are about costs of dementias in general, but they do no differentiate costs for the case of EYOD. Many studies highlight the increased costs for EYOD but very little included evidence of that. 135 papers were selected. Finally, only two were studies providing data. EYOD reduce the odds to get or maintain a job. Most of the care is provided by informal caregivers. The costs in EYOD are 39.26% higher among EYOD than in late onset. Conclusion:There is a lack of studies about social and indirect costs in EYOD. More evidence is needed.
