METHODS
Data sources:Medline and PsycINFO (2000 to April 2006). Earlier studies were covered by a previously published review.*
Study selection and assessment:English-language studies that evaluated screening tests for dementia, suitable for use by generalist physicians, in people >60 years of age without clinically obvious dementia. Included studies were required to use an acceptable criterion standard to diagnose dementia. Studies in patients in institutions or memory clinics or with <6 years of education and those involving diagnostic imaging or laboratory or physiological tests were excluded. 29 studies involving 42 assessments of 25 screening instruments met the selection criteria. Quality of individual studies was assessed based on sample size, participant selection, and use of a credible reference standard applied blindly and independently.
Outcomes:positive (+LR) and negative (–LR) likelihood ratios.
