Is ADHD not a developmental disorder, causing an underdevelopment or delayed development of the frontal lobe? It seems incorrect to refer to this as "brain damage"?
Edit: I guess I'm referring to the official "medical narrative" as it stands.
I do happen to believe that the DSM-5 criteria is wildly out of date for ADHD diagnosis and at odds with the findings of a lot of more recent research. But I'm just questioning the "brain damage" terminology - I've never heard it described in that way before.
Most medical professionals that I've encountered stick firmly to the line that ADHD is a lifelong condition that develops in very early childhood and is not currently curable. You can almost entirely alleviate symptoms. But this is != a cure.
My current understanding is that if your ADHD is "curable" by eg. vitamins or a change in sleep pattern then it is unlikely to be considered to have been ADHD in the first place (but the symptoms may well have been indistinguishable). That's not to say that the symptoms of ADHD can't be greatly reduced by these things.
However, I'm not a doctor. Happy to be corrected by anyone who is.
