Ganguli M, Ratcliff G, Belle S, Huff FJ, Kancel MJ, Fischer L, Kuller LH: Effects of age, gender, and education on cognitive tests in an elderly rural community sample: norms from the Monongahela Valley Independent Elders Survey (MoVIES). Neuroepidemiology, 10 (1); 42-52, 1991.
A random sample of 1,350 persons aged 65 years and older in a rural
community underwent cognitive screening as part of a survey to establish a
population-based registry of dementing disorders. The screening battery
included the neuropsychological tests of the assessment protocol used in
the National Institute on Aging multicenter Consortium to Establish a
Registry for Alzheimer's Disease (CERAD). This paper reports a large body
of normative neuropsychological data from this sample with members of
relatively low socioeconomic status. Age, sex, and educational level were
found to have statistically significant effects on test scores. The
implications of these findings for the establishment of screening cutoff
scores are discussed.
