15 June 2021	Amended	The title and objectives have been changed to make it clear that screening tests alone cannot give a diagnostic formulation. There have been no other changes. Similar changes have been made to other Cochrane diagnostic test accuracy reviews relating to dementia. These changes were made by Cochrane Dementia and Cognitive Improvement in conjunction with the Cochrane Mental Health and Neuroscience Network and the review authors, following feedback from a group of dementia researchers, expressing concern that the review titles implied that short screening tests could make a diagnosis of a dementia subtype like Alzheimer’s disease. This interpretation was not intended, but the revised titles and objectives clarify the reviews’ scope.
