Specific keywords, MeSH terms, and Emtree terms were used to search for articles on dementia and getting lost. A total of 10,523 articles published from 2011-2020 that matched the search criteria were extracted. After screening the topics and deleting repetitions, 64 articles were selected for further analysis.
