  • a medical term meaning 'of unknown cause' as in: idiopathic epilepsy.

    A doctor friend used to say, "imagine that you are having seizures and you don't know why. You rush off to a fancy diagnostic clinic which does extensive neurological and other testing. At last you sit down with the doctor who gives you a diagnosis of 'Idiopathic Epilepsy.' which means, 'you are having seizures and we don't know why'

    You are troubled to hear that you have epilepsy, and you spent a lot of money but you are somewhat relieved that at least you now have a 'diagnosis.' "

    As my doctor friend said, "you can't send them a bill that repeats back their own words ie. 'you have seizures and we don't know why'. When they hear the long medical term they think you really KNOW something!"
