![]() Especially, computer tests require further research. ![]() However, most tests are only validated in a memory clinic setting and description of the psychometric properties of the instruments is limited. ConclusionsĪ large number of screening tests for AD are available. Regarding computer tests, validation studies were only available for 7 out of 12 tests. Based on the number of studies (31 articles) and the sensitivity (84%) and specificity (74%) values, the Montreal Cognitive Assessment (MoCA) seems to be a promising (pencil and paper) screening test for memory clinic testing as well as for population screening. Eighty-nine papers discussed pencil and paper tests of which 80 were validated in a memory clinic setting. Out of 1454 papers, 96 clearly discussed the psychometric properties of the instruments. Therefore, the same databases were searched again to identify papers that described the psychometric properties of the instruments meanwhile applying diagnostic criteria for the diagnostic groups included. In a second step, the psychometric quality of these instruments was evaluated. ![]() All full-text papers about cognitive screening instruments for the early detection of AD were included, resulting in the identification of 38 pencil and paper tests and 12 computer tests. Only papers written in English or Dutch were considered. Methodsįirst, a systematic search of titles and abstracts of PubMed and Web of Science was conducted between February and July 2015 and updated in April 2016 and May 2018. The objective of this systematic review was (1) to give an overview of the available short screening instruments for the early detection of Alzheimer’s disease (AD) and (2) to review the psychometric properties of these instruments.
