Disease Nosology and Precision Medicine

Modern disease classification emerged in the late 1800s, contrasting with earlier, more general descriptions.
Disease definition relies on clinical and pathological observations.
Diseases were often categorized by the organ affected and late-stage symptoms, as autopsies were necessary for correlations.
Morgagni's work, "De Sedibus et Causis Morborum," pioneered this approach by correlating clinical cases with over 600 autopsies from Padua University, establishing an anatomical basis for disease.
This approach used inductive reasoning and Occam's Razor, simplifying disease definitions.
While this approach to describing diseases has been effective, its oversimplified nature has limitations.
Key limitations include inability to distinguish different diseases with similar symptoms and underlying pathology(e.g., different causes of kidney failure).
Growing understanding of disease etiologies is improving classifications, especially for neurodegenerative disorders, lymphomas, and other conditions.
Accurate disease classification improves prognostic predictions for individual patients.
Current therapies are sometimes ineffective due to a lack of understanding of underlying disease drivers at a molecular level.
