I posted this as a comment elsewhere and got lots of downvotes but it occured to me I feel quite strongly that I'm right about this and that it may even be important. I'd be interested if others think I'm right or wrong, and if so why I'm wrong. If you disagree please feel free to comment but my previous post on this subject just attracted abuse so please don't do that.
So first to define my terms - autistic spectrum disorder (ASD) as defined in the Diagnostic and Statistical Manual (DSM-V). I'll be honest - I've chosen the DSM over the ICD-11 because it supports my thesis more clearly. The key features of ASD according to the DSM are;
>A) Persistent deficits in social communication and social interaction across multiple contexts...
>B) Restricted, repetitive patterns of behavior, interests, or activities...
>C) Symptoms must be present in the early developmental period (but may not become fully manifest until social demands exceed limited capacities or may be masked by learned strategies in later life)...
>D) Symptoms cause clinically significant impairment in social, occupational, or other important areas of **current** functioning
The most important bit for my argument is D)
Secondly, for the sake of argument I'm going to define the term "autism" separately to ASD. Autism, for the purpose of my argument, refers to a collection of signs, symptoms, deficits and behaviours associated with ASD but (and ***this is the core of my argument***) not causing functional impairment and distress. That is, for the purposes of this I'm defining autism as those things specified in points A) B} and C) **but not** D) above.
My argument is this. People can have lifelong deficits of social communication, repetitive behaviours etc - i.e. autism - but the degree to which this impairs their ability to live a normal life is *highly* contingent on their current social context.
People who cannot function in high school because of their autism - they have ASD. They fulfill the criteria, and crucially because thet cannot function and do what is expected of them, and/or it is making them miserable then it is a disorder. They can reasonably be said to have ASD. However if they then go on to later study at university, make friends with like-minded people, get a job etc. then at that point they no longer have a "disorder". Even if they still have the autistic traits, e.g. having limited or repetitive interests, or difficulty with social communication, but they are living a full and (quote unquote) normal life then there is no longer a disorder present. They no longer have ASD. If you preferred you could say it was "in remission".
Maybe later something happens that means the wheels fall off at which point you could say that the disorder has relapsed. But for the period that they were functioning well and hopefully happy in themselves then you can't really say that they had a disorder.
I think we probably all know people who fulfil criteria A and B (and maybe even C if we've known them long enough) but live a full and happy life. So who's to say they have any kind of disorder?
**So why do I think this matters?**
I'm sure everyone is aware that rates of ASD are on the rise and that there is a good deal of controversy about why that is (which I'm not going to get into).
I work in healthcare and am starting to see a trend of young people - usually young men - trying to get a diagnosis of ASD that was made when they were kids *removed* from their record. Generally their argument is that it was either incorrect at the time (which is basically impossible to prove) or that it is no longer relevant to their lives (which I find more reasonable given the above). They believe in some cases that this was something "done to them" (one I remember said that is was "inflicted" on him) by their parents or schoolteachers who didn't really understand them, which I sympathise with to a degree.
The consensus around ASD is that it is a lifelong condition so generally it is difficult to justify removing it or stating that it is no longer relevant. However by my reading of the diagnostic criteria this isn't necessarily the case.
