Participants with more income drops also scored worse on how much time it took to complete some tasks. The results were the same after researchers adjusted for other factors that could affect thinking skills, such as high blood pressure, education level, physical activity and smoking. There was no difference between the groups on tests that measured verbal memory.
Of the study group, 707 participants also had brain scans with magnetic resonance imaging (MRI) at the beginning of the study and 20 years later to measure their total brain volume as well as the volumes of various areas of the brain. Researchers found when compared to people with no income drops, people with two or more income drops had smaller total brain volume.
People with one or more income drops also had reduced connectivity in the brain, meaning there were fewer connections between different areas of the brain.
