What about Freud, conversion disorder and neurastenia?
When I was starting out in medicine in the 1970s and early 80s these things made zero impact on my day to day thinking as a physician. The occasional patient would appear with apparent unconsciousness or paralysis that was clearly due to some mental process but rather than go to Freud, who was largely seen as a historical curiosity by physicians, we tended to think more in terms of fabricated illness. There was usually clear evidence that the person knew what they were doing. And these cases were rare.
By the 1990s there were psychologists in all the rheumatology clinics. The biopsychosocial approach suddenly became trendy. I was expected to send my rheumatoid patients along for psychology projects. I said no thanks.
