[Djvacto]

Your diabetes analogy fails, because ADHD does not have an environmentally-caused Type 2.

ADHD is hereditary, genetic, and has to do with how the brain tends to be wired in that individual. ADHD can be helped through environment and habit changes, and impacts can be reduced, but you cannot cure it.

It seems that you think ADHD is not a real disease, given your quotes around the words "disease", "cure", etc. If some people are mis-diagnosed, it doesn't invalidate all the others.

ADHD is caused by a mix off environment and genetics. That environment could include several inputs, like diet, air pollution, etc.

And ADHD is not a disease, it is a disorder. There is no biological markers yet for a diagnosis either.
