The human brain is arguably the most complex system on the planet. We have a very poor understanding of how it functions so we fall back to the old, "is this useful metric" and DISORDER only refers to things that are less than optimal.

There are plenty of environments where a mild level of ADHD is not an issue; unfortunately children are expected to be able to sit and concentrate for several hours a day. In that context the term DISORDER is appropriate which is not to say it can be compensated for just that there is an issue. There are plenty of ways to compensate for poor vision and people are starting to think of mental issues in those terms. Unfortunately it's harder to change the environment or give extra attention than a cheap external prosthetic. Thus, drugs are often the first choice, even if they have minimal value or just trade harming the user to help those around them.
