Nosology

Nosology is a branch of medicine that deals with classification of diseases.

Diseases can be classified by etiology (cause), pathogenesis (mechanism in which the agent causes disease) or by symptom. Alternatively, diseases can be classified according to the organ system they involve, but this is often complicated as many diseases affect multiple organs.
