Current policy in many countries is aimed at increasing the rates of diagnosis of dementia and cognitive impairment.1 2 3 This policy drive has been accompanied by research into early detection of dementia, including preclinical identification of underlying neurobiology that might later be associated with dementia.4 Although the clinical features of people with established dementia are unmistakable,5 6 the ability of these preclinical features to predict future disease is less clear. Nevertheless, the belief that there is value in screening for “pre-dementia” or mild cognitive impairment is creeping into clinical practice, with the resulting overdiagnosis having potential adverse consequences for individual patients, resource allocation, and research.
