I asked my daughter's neurologist what he thought would happen to her diagnosis after the change and his response was basically "She is autistic no matter what the diagnostic criteria says." IOW, I think there will be some clinicians who continue to use their experience and expertise.
IMHO, there are some people, like my daughter, who do not neatly fit any criteria--so it doesn't really matter what the criteria is--but if you really understand what autism is at the most fundamental level, you can see it. For her I think the biggest defining characteristic is the inability to learn anything incidentally, even though she has superior intelligence. She has had to learn everything from pointing, to waving, to speaking, to approaching other kids, to having reciprocal communications, etc. in a very systematic manner. This is a common trait of many people on the spectrum that I have crossed paths with, but it is nowhere in the diagnostic criteria. Or, I don't know...maybe it's just her and the people I've met?
The initial criteria were very upsetting for me because I know many kids who would lose their diagnoses and be left without support and assistance at school. However, the most recent ones I saw were broadened a bit. As long as people are not left to struggle needlessly, I don't see the harm in the change, though I still suspect the bottom line reason for the changes was...well...the bottom-line. That part leaves me sick.
