Stress-related illness is not a new disease. Greek physicians of the school of Hippocrates (460 – 377 BCE) recognized a disorder characterized by symptoms commonly seen in stress illness today: palpitations, migrating pain, difficulty breathing, a lump in the throat and others. This was diagnosed exclusively in women and attributed to the uterus wandering around inside the body. The Greek word for uterus (hystera) gave the disorder its name, hysteria, and this was a common diagnosis through the early 20th century. The term was finally dropped by the American Psychiatric Association in 1980, replaced with conversion disorder.
