The rates of high blood pressure among African Americans, as a group, are the highest in the world. The implications for higher average blood pressure include complications for many major chronic conditions, such as cardiovascular disease and diabetes. Less well studied is the effect of blood pressure on the cognitive functioning of African Americans. The purpose of this study was to examine the effect of blood pressure on memory measures in a sample of adult African Americans. Analyses were conducted on a sample of 361 African American adults (mean age 61.50 years, standard deviation 9.39 years). We found significant correlations between systolic blood pressure and most cognitive measures but only for one of the measures and diastolic blood pressure. Regressions revealed significant effects for systolic blood pressure on Digit Symbol, Telephone Interview of Cognitive Status, and Immediate Recall on the Wechsler Logical Memory test. These findings suggest that blood pressure is a source of individual variability in cognitive aging among African Americans. [ABSTRACT FROM AUTHOR]

The article offers information on a study which examined the effects of blood pressure on the memory of older African Americans. Results of the study, which gathered information from 631 African American adults, showed links between levels of systolic blood pressure and cognitive functioning and the importance of blood pressure in aging and health processes.
