What is your beef besides the fact that I posted it? Most kids are diagnosed while in school. How many parents take their kids for assessment before school? With some kids it may be apparent from shortly after birth but the vast majority of kids being diagnosed with many of these so called disorders are done so in schools because teachers are not trained nor do they have the time to deal with "problem" kids. Most of the disorders mentioned in the OP are made up to sell drugs and placate teachers. I say, put the teachers on Ritalin and leave the kids alone.
Gawd, they even now have a "disorder" for people who do not want to eat food poisoned by pesticides or herbicides. If you want to eat organic you have a mental disorder. They even have a drug for "restless leg syndrome". The book on mental disorders went from a couple of hundred pages to thousands of pages in the last few decades. I am beginning to think that shrinks are not qualified to diagnose any more than teachers are. The whole medical profession has become nothing more than legalized drug pushers.
And my "rant" has everything to do with the OP. If you can't make the connection, that is your problem.
How the f-ck would you know what does or doesn't happen in the real world based in reality?
