Alan is correct. People routinely say things like āMS was thought to be hysteria until the advent of the MRIā when in reality the same neurologist most famous for describing both MS *and* hysteria in the nineteenth century differentiated them clinically AND pathologically.
It's remarkable how off Zeynep is. Just repeating talking points, utterly unfamiliar with the history of these conditions.
MS and ulcers were psychologized?
False. MS was never "psychologized," it was widely understood to be a neurological condition since Charcot in the late 1800s. Only very, very fringe people psychologized it, and that happened far later.
Ulcers were not psychologized. Everyone understood that the pain people experienced came from sores in the stomach lining. They never claimed that was "psychogenic." The question was what *caused* the sores. Most thought stress! Then h pylori was discovered to be necessary for (most) ulcers.
However, many people have h pylori (50%)! Not everyone gets ulcers. To this day, there's still debate about why some people get them and others don't. Stress remains a likely culprit.
