The criteria specifies that "There is clear evidence that the symptoms interfere with, or reduce the quality of, social, school, or work functioning."
I don't see this as being the same thing as ADHD being a NEGATIVE. It's like saying that being short is a disorder because it interferes with picking fruit from tall trees, and being tall is a disorder because it interferes with your ability to be a jockey. While both of these are true, it's ultimately condescending to frame either of these as a "disorder" simply because both aspects negatively interfere with one lives in certain contexts.
The diagnostic criteria does not rule out that one can be an exceptional A+ student which still has their symptoms interfere with school functioning if they're for instance repeatedly sent to the principals office for disrupting classes. Simply the very fact they have an issue that other children typically do not typically have, wipes away all consideration of their positive merits, and justifies a rather insulting label. To me, this is reflective of the typical feeling superior to those who are atypical.
>I think the threshold for where we think some Neurotype is affecting our life has been lowered dramatically.
Undoubtedly, but this doesn't in itself justify not lowering the threshold.
