organic disease
C1-C2 / Low FrequencyFormal, Technical, Medical
Definition
Meaning
A medical condition caused by structural, demonstrable changes in bodily organs or tissues, as opposed to one of purely mental or functional origin.
In historical or less clinical contexts, it can sometimes refer more broadly to any physical illness with a clear physiological basis.
Linguistics
Semantic Notes
This term is primarily used in technical medical and psychiatric fields to differentiate from 'functional disorders' (e.g., certain anxiety disorders) or 'psychosomatic illnesses'. Its usage implies objective, identifiable pathology. In non-technical speech, it is rare and potentially confusing.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'органическая болезнь' in non-medical contexts as it may sound strange. In general Russian, 'органический' relates more to farming/food. The medical equivalent is 'органическое заболевание', but it is still highly technical.
Common Mistakes
- Using it interchangeably with 'serious disease'. Not all serious diseases are discussed as 'organic' (e.g., some cancers are, but severe depression might not be).
- Using it in casual conversation where 'physical illness' is meant, leading to confusion.

FAQ
Frequently Asked Questions
No, this is a common misunderstanding. In medicine, 'organic' refers to bodily organs/tissues, not to farming methods. The terms are homographs with different meanings.
Yes, if they have a clear, demonstrable physical cause in the brain. For example, dementia caused by Alzheimer's disease (with brain atrophy) is considered an organic disease, whereas generalised anxiety disorder without such physical markers is typically not.
No, it is a specialised medical term. In everyday language, people say 'physical illness', 'medical condition', or use the specific name of the disease (e.g., pneumonia, cancer).
The main clinical opposite is a 'functional disorder', where symptoms exist without currently detectable structural or biochemical abnormalities in the organs involved.
