Summary
This study redefines disease attributes, moving beyond outdated concepts to modern logic. It proposes that patient characteristics must be population or individual abnormalities linked to therapeutic, social, or medical concern.
Area of Science:
- Medical Philosophy
- Logic in Medicine
- Disease Definition
Background:
- Historical influence of scholastic doctrines on disease concepts.
- Need for modern class logic premises in defining disease.
- Scadding's criteria for disease attributes: species norm deviation and biological disadvantage.
Purpose of the Study:
- To redefine the distinguishing attributes of the universal class of patients.
- To propose a new framework for identifying disease based on modern logic.
- To align the definition of disease with contemporary medical practice.
Main Methods:
- Applying modern class logic to the concept of disease.
- Analyzing Scadding's criteria for disease attributes.
- Developing a new set of criteria based on population/individual norms and concern.
Main Results:
- Proposed attributes for the patient class must be abnormal relative to population or individual norms.
- These abnormalities must be associated with therapeutic, social, or medical concern.
- The proposed criteria align with current diagnostic practices.
Conclusions:
- Disease definition requires attributes abnormal to population or individual norms.
- The presence of therapeutic, social, or medical concern is crucial for identifying disease.
- This updated framework offers a more practical approach to disease diagnosis.
