Totally on board with your comments on disparagement, but there's been a rash of autism diagnoses in my daughter's school to the point where in some classes 20% of students have been diagnosed as autistic. I feel at that point people are diagnosing personality, and it's using the (UK) special educational needs system to force schools to pay attention to different learning styles. (My daughter's school is actually pretty good on that front if you point it out to the staff, so I'm not sure what's triggering it particularly in her school, but it may be to do with releasing government funding for extra classroom assistants).
