The aim of this study was to compare patterns of cognitive decline in older Latinos and non-Latinos. At annual intervals for a mean of 5.7 years, older Latino (n=104) and non-Latino (n=104) persons of equivalent age, education, and race completed a battery of 17 cognitive tests from which previously established composite measures of episodic memory, semantic memory, working memory, perceptual speed, and visuospatial ability were derived. In analyses adjusted for age, sex, and education, performance declined over time in each cognitive domain, but there were no ethnic group differences in initial level of function or annual rate of decline. There was evidence of retest learning following the baseline evaluation, but neither the magnitude nor duration of the effect was related to Latino ethnicity, and eliminating the first two evaluations, during which much of retest learning occurred, did not affect ethnic group comparisons. Compared to the non-Latino group, the Latino group had more diabetes (38.5% vs. 25.0; χ2[1]=4.4; p=.037), fewer histories of smoking (24.0% vs. 39.4%, χ2[1]=5.7; p=.017), and lower childhood household socioeconomic level (−0.410 vs. −0.045, t[185.0]=3.1; p=.002), but controlling for these factors did not affect results. Trajectories of cognitive aging in different abilities are similar in Latino and non-Latino individuals of equivalent age, education, and race. (JINS, 2016, 22, 58–65)

He was born in 1893 in the New York brownstone house near Washington Square where he lived all his adult life, a member of Edith Wharton's settled, circumscribed world of ordered privilege whose affluent, well-travelled, and sophisticated men and women traced their lineage back to the Founding Fathers and their principles to the American Revolution. His father was an artist who served as Consul General to Italy, and Armstrong was brought up in a milieu which took for granted the fact that there existed a world outside the United States. He died in 1973, as the United States finally withdrew from the Vietnam War, a conflict which deeply distressed him and shattered the foreign policy elite and its controlling consensus, whose creation had been a major part of his life's work. In an obituary notice Arthur M. Schlesinger, Jr., described him as “a New York gentleman of a vanishing school,” who “treated every one, old or young, famous or unknown, with the same generous courtesy and concern.”
