Definition

Noun: - A disease of unknown origin: An idiopathic disease is any illness or medical condition that arises spontaneously or from an internal dysfunction of the body, where the specific cause is unknown or cannot be determined.

Usage Notes

• The term "idiopathic" is primarily used in medical and clinical contexts to classify conditions whose etiology (cause) is not understood. It is a formal diagnostic label.
• It describes the state of medical knowledge about a condition's cause, not the condition itself. Over time, as research advances, a disease once called idiopathic may be reclassified once its cause is discovered.

Examples

• Noun:
  • The patient was diagnosed with an idiopathic disease, so the doctors focused on managing the symptoms rather than treating a known cause.
  • Essential hypertension is often considered an idiopathic disease because its exact cause in a specific individual is usually unknown.

Advanced Usage
