The goal of this effort, set by the National Institute on Aging (NIA), is to devise a cognitive assessment that meets the following criteria: 1) Can be administered in the home by a survey interviewer in about one hour, 2) Has sufficient overlap with the 2002/03 HRS-ADAMS study that it can be used to establish trends in prevalence of dementia and cognitive impairment without dementia, and 3) Can be administered comparably and lead to comparably valid diagnoses in other developed and developing countries where HRS-type surveys are conducted. This goal is achievable because of substantial investment by the NIA in data collection in population studies focused on dementia. There is thus now an empirical basis for making test selection. Informant reports are a key element of most population-based approaches to assessment to establish the presence or absence of change in cognitive ability and of limitation in activity resulting from change. We intend to include informant reports in our data collection protocol and in the diagnostic algorithm. This document is focused on cognitive testing of the subject.
