Organic disease

An organic disease is one which involves or affects physiology or bodily organs. A disease in which there is a physiological change to some tissue or organ of the body.

Organic disease may also be used to mean a condition that is not caused by an infection.

The term "Organic Cause" also features in Obesity disorders, where for example "Regulatory Obesity" is a failure to regulate food intake but with no organic cause, whereas Metabolic Obesity involves an organic cause.

In neuropsychology the concept of an organic condition, as opposed to functional causes, is less used now than traditionally (for example Organic brain syndrome), but may still crop up in debates over certain thorny issues, such as Functional neurological deficit.
