The associations between depression and medical illness are more intimate and more extensive than previously appreciated. We are beginning to see how the disease processes that overtake the body also affect the brain, and conversely how brain disorders like depression can affect medical illnesses. Depression influences the occurrence, presentation, course, and outcome of many medical illnesses, and conversely, comorbid medical illnesses can affect the onset, presentation, course, and outcome of depression. We owe this enhanced understanding to recent advances in scientific methods, to more precise clinical observation, and to greater diagnostic precision.
