In medicine, the term syndrome is the association of several clinically recognizable features, signs, symptoms, phenomena or characteristics which often occur together, so that the presence of one feature alerts the physician to the presence of the others. In recent decades the term has been used outside of medicine to refer to a combination of phenomena seen in association.
The term syndrome derives from the Greek and means literally "run together," as the features do. The term syndrome is most often used when the reason that the features occur together (pathophysiology) has not yet been discovered. A familiar syndrome name often continues to be used even after an underlying cause has been found. Many syndromes are named after the physicians credited with first reporting the association; these are "eponymous" syndromes. Otherwise, disease features or presumed causes, as well as references to geography, history or poetry, can lend their names to syndromes.
