The authors of a recent study published in Neurology sought to, “examine associations between complexity of main lifetime occupation and cognitive performance in later life.” The study collected the childhood IQs of 1066 people from a 1936 study. The authors then grouped the participants according to profession and assessed their cognitive performance at age 70. The authors found that people who work at complex jobs generally did better on a range of cognitive ability measures and were associated with better cognitive performance in later life.
