Misdiagnosis the other way: someone actually without ASD diagnosed as being on the spectrum

I have tried to find the answer to this via web searches, but I just can't get an answer. I would like to know the statistics for people who have misdiagnosed with ASD when they are later conclusively found not to have ASD (i.e. they have some other condition, or they don't have any condition at all). All I get when I search are stats for people misdiagnosed the other way: people on the spectrum who were wrongly diagnosed with something else at first, or people on the spectrum who were not thought to have any condition at all until ASD was considered.

Does anyone know the answer to this? Has anyone here been diagnosed with ASD only to find out later that you're not on the spectrum, or know someone this has happened to?

Can anyone point me to a site with stats for this type of misdiagnosis?

Is it possible to fake being on the spectrum to the extent that a professional expert would wrongly diagnose someone with ASD? Would anyone want to do so?

Any info whatsoever about this would be greatly appreciated.

  • I didn't really fulfill all the criteria so the person assessing me made them fit because she was convinced I should get a diagnosis and at hindsight I think the more upset I got about this the more convinced she became. I don't think I have obsessive interests, even if I may find 20 geocaches in a day, lots of people do that or a lot more. And yes, I can forget about the time solving puzzles or so, also for a couple of hours, but this will only happen when I actually have that time and it doesn't matter. So she made this fit. I also don't think I speak in any unusual way (friends don't think that either) but to fit the criteria she decided I make strange breaks. Could it be because English is not my first language and she made me talk about things I don't usually talk about? So I'm not sure myself. The things that have got me into trouble do unfortunately fit better and having been to a Go-Ape thing the other day, for autistic children and their parents (so didn't really fit but the climbing was great) I have to admit I felt reminded of myself a couple of times, especially when watching siblings, and it didn't really matter which one was the older or younger one. Anyway, I think I could just as well not have got a diagnosis, and I think there will be a fair few people like this. It's not measurable, so it is somewhat subjective.
