Dr. Zeki Al Hazzouri and her colleagues examined the effects of sustained poverty and perceived financial difficulty on cognitive function in midlife using income data for about 3,400 adults who took part in the ongoing Coronary Artery Risk Development in Young Adults (CARDIA) prospective cohort study. The CARDIA study included black and white males and females 18 to 30 years of age at the start of the study in 1985-86.
