title: Normative data for elderly adults: the Maine-Syracuse study.
abstract: The primary objective of this study was to provide supplementary normative data on aging and cognition from an ongoing community-based study. This dementia- and stroke-free sample (age range = 70-89; mean = 77.5) consisted of 228 women and 155 men participating in the Maine-Syracuse Longitudinal Study at waves 6 to 7 (2001-2009). The authors employed a battery of 23 widely utilized clinical cognitive tests. In this cross-sectional study, the authors focus on subjects 70 to 79 (n = 248) and 80 to 89 (n = 135) years old, and provide preliminary data for a smaller number of subjects aged 90 to 98 years old (n = 14). More highly educated and younger participants exhibited better performance on cognitive tests. Education was not significantly associated with every cognitive outcome, nor was age cohort membership. The addition of cardiovascular disease (CVD)/health variables to a model including age, education, and gender main effects provided statistically significant increases in R² (range = .021-.084) of performance on some tests. Results are discussed in relation to this study's value with respect to determining cognitive impairment in individuals free from probable dementia or stroke.
