In page Nosology:

"

Traditionally diseases were defined as syndromes by their symptoms. When more information is available, they are also defined by the damage they produce. When cause is known, they are better defined by their cause, though still important are their characteristics. This leads to a branching differentiation in which a clinical syndrome (pattern of signs and symptoms) can come to be understood as a nonspecific finding shared by a group of disease entities or endotypes. For example, concepts such as murrain and the grippe that were formerly undifferentiable to humans and thus understood as a single disease later can be logically unraveled as separate diseases with similar clinical presentations. Thus, nosology is dynamic, reclassifying as science advances.[citation needed]
