Digital Cognitive Tests for Dementia Screening:  A Systematic Review

Background: The number of people with dementia is increasing dramatically. With the outbreak of the COVID-19 pandemic, use of digital screening tests can play a significant role in the remote and timely detection of people with dementia. The aim of this study is to review digital cognitive tests for dementia screening. Methods: We searched Web of Science, ProQuest, PubMed, Scopus and Cochrane in June, 2022. 1348 articles were identified. After reviewing the articles and excluding duplicates and irrelevant articles, thirty-two articles met our inclusion criteria. Results: : The studies were classified into 3 groups as follows: 1) mobile-based screening tests 2) desktop-based screening tests 3) web-based screening tests. Conclusion: The use of digital cognitive tests, especially mobile-based screening tests, facilitates timely diagnosis of dementia. Development of AI-based screening tests and use of technologies such as virtual reality and chatbots will set a bright future in early detection of dementia.
