Study Notes
Pathophysiology Overview
- Pathophysiology examines the processes and changes in the body due to disease.
- It differentiates between symptoms (felt by the individual) and signs (observed by clinicians).
Key Components of Pathophysiology
- Clinical Course: The progression and development of a disease over time.
- Prognosis: The forecast of the likely outcome of a disease, including chances of recovery or complications.
Focus Areas
- Investigates structural, biochemical, and functional alterations in cells, tissues, and organs due to diseases.
- Utilizes techniques from molecular biology, microbiology, immunology, and morphology to interpret disease manifestations.
Core Aspects of Diseases
- Aetiology: The cause or origin of the disease.
- Pathogenesis: The mechanism through which the disease develops.
- Molecular and Morphological Changes: Biochemical and structural alterations in body cells and organs.
- Clinical Manifestations: Functional consequences arising from the aforementioned changes, impacting patient health.
Aetiology of Diseases
- Numerous causes exist for diseases, categorized mainly into genetic and acquired factors.
- Genetic causes include inherited mutations that can predispose individuals to certain diseases.
- Acquired diseases arise from various factors:
- Infections caused by pathogens.
- Nutritional disorders resulting from dietary deficiencies or imbalances.
- Chemical or physical agents that may induce harm or illness.
- Interventions by allied health professionals that could exacerbate existing conditions.
Pathogenesis of Diseases
- Refers to the progression of a disease from onset to resolution.
- Defined as the series of cellular and biochemical changes that occur during disease development.
- Pathogenesis is crucial for understanding disease mechanisms, allowing for:
- Insights into how diseases evolve over time.
- Evaluation of the impact of different interventions at various stages of disease progression.
- Can be studied at multiple levels to gain a comprehensive understanding of disease dynamics.
