I was a big fan of the show, but I don't see how a guy who just tried various treatments until he got it right was a diagnostic expert.
He thought outside the box, which would be helpful if you have something weird and disgnosis-resistant. But remember the old saying “If you hear hoofbeats, think horses, not zebras”. Thinking outside the box, while entertaining for TV, if carried to extremes can hinder more than help. You have to be able to balance both.
...because the are tens of thousands of possible treatments...and getting it down to a handful is an accomplishment.
I watched a couple of seasons, until it got to be too much of a soap opera. Did anyone else notice that most of the first season’s diagnoses were lifted from the book The Medical Detectives by Berton Roueche?
