Etymology: Thomas Addison was a physician at Guy's Hospital in London, and in 1855 he published a short monograph describing a disease that involved bronze-coloured skin and the failure of the adrenal glands. Within a few years, the condition was being called Addison's disease in medical writing, and the adjective "Addisonian" followed the same pattern: a surname with the suffix "-ian" attached, the way English forms "Darwinian" from Darwin or "Freudian" from Freud. The word therefore names no disease itself but describes anything tied to that disease, such as an Addisonian crisis or Addisonian symptoms. The noun use came from the same root. Doctors used "Addisonian" as a term for a patient with the disorder, a usage that sounds clinical and blunt today. Because the word is built on a person's name, it is capitalised in formal writing, though the lowercase form appears in many medical texts.
