ADD/ADHD is a psychiatric disorder. This means that its existence is confirmed purely by subjective citeria.
You're wrong. You appear to be one of those who opposes the existence of ADD/ADHD on ideological grounds. Why?
Perhaps, perhaps not. I do know what the doctor showed me. And I do know it helps me, personally.
This is an "ideological" malady, inasmuch as certain people will insist -- loudly, and often with flecks of spittle on the sides of their mouth -- that this which affects me, does not.
Luckily, the medical community will ignore the ideologically extremist on this issue, and continue treating me for a malady that -- at least in my life -- is 100% real.
