organic disorder
Noun: A medical condition or illness that is caused by a detectable, physical change in the structure or function of a specific organ or bodily system. This contrasts with disorders that are considered functional, where no such physical abnormality can be identified.
This term is primarily used in medical and psychological contexts to classify the origin of a disease or syndrome. It emphasizes that the root cause is a tangible, physical problem.
- The patient's memory loss was diagnosed as an organic disorder resulting from a small stroke.
- Certain forms of dementia are considered organic disorders because they involve measurable brain degeneration.
- The doctor ruled out an organic disorder before considering a diagnosis of a functional gastrointestinal issue.
- In psychiatry, the term is used to distinguish conditions like organic brain syndrome (caused by physical injury or disease) from those like schizophrenia, where the primary etiology is not fully understood as a structural lesion.
- The phrase "rule out organic disorder" is common in diagnostic processes, meaning to first check for physical causes before attributing symptoms to psychological or functional origins.
- Organic: (Adjective) Of, relating to, or derived from living organisms; or, in medicine, relating to or affecting bodily organs. (e.g., ).
- Functional Disorder: (Noun) A disorder where symptoms exist without clear, detectable physical or structural changes to explain them. This is often contrasted with an organic disorder.
- Physiological disorder
- Structural disorder
- Somatic illness (in specific contexts)
- Functional disorder
- Psychogenic disorder
- Non-organic disorder
The key distinction lies in the presence of a "detectable physiological or structural change." This means the disorder has an objective, physical basis that can, in principle, be observed through tests like imaging (MRI, CT scan), biopsies, or laboratory analyses. The term does not describe the severity of the condition, only its proposed physical origin.
