MODR 1760 Lecture Notes - Lecture 13: Causal Structure
Document Summary
All addicions can be seen as diseases, but not all diseases can be addicions. Disease concepts are paricularly interesing from this theoreical perspecive, because they display a rich causal structure schemaized in igure 1. Symptoms are the observable manifestaions of a disease, which can develop over ime in paricular ways that consitute the expected course of the disease. The symptoms arise from the cause or causes (eiology) of the disease. Treatment of the disease should afect the symptoms and course of the disease, oten by afecing the causal factors that produce the symptoms. Disease concepts are causal networks that represent the relaions among causes, disorders, symptoms, and treatments of diseases. Being symptomaic does not necessarily mean that symptoms must be visible, addicion sill has symptoms which the addict can hide, yet they are sill there.
