Syndrome
This is a complex of symptoms linked by a common pathogenesis but with various causes, e.g., Addison’s syndrome (adrenal insufficiency). Medicine and psychology use the term to denote a group of clinically appearing symptoms noticed by the physician and the patient (symptoms) and their physiological cause (disease, disorder) that has not yet been identified or is unknown. Sometimes the term “syndrome” is adopted as the name of a disease or disorder or used when a set of corresponding symptoms can be caused not by one but by several different disorders or diseases.
