In a psychiatry tutorial, we learned just how focussed we are on physical symptoms (I don’t think that was its goal, but I learned it in anycase).
Students had to act out certain psychiatric symptoms, while the other students guessed.
One student was being “interviewed”, rattled off a few sentences, and then abruptly stopped:
Someone shouted: ABSENCE SEIZURE!
The real answer was “thought blocking”.
Another student scratches wildly at his arms, informing the doctor that he think he has lice under his skin.
Someone shouts: PRURITIS!
The real answer is formication (not to be confused with fornication).
At any rate, it’s not a wonder that psychiatric conditions are so often misdiagnosed. The great impersonator, indeed.
