You know what? I kinda see A.D.D. as just a lame excuse. It doesn't really exist.
It was made-up by some Psych major to win a nobel prize, or make tons of dough off of Riddilin.
Because I know plenty of folks, aged 50+, who might have had some trouble in school, but...public schools' then did not treat you with 'kid gloves' like they do today. If you did not do your homework, they did not say you needed medication, and had to be given less work...They kept you after school in detention, or made you go to study hall, or called your parents', and the dean would take his paddle to your ass. You don't see too many of the previous' generations wigging out, and running into school with an automatic rifle, killing they're classmates. They just sucked it up and did they're work.
ADD and ADHD are just an excuse for schools' to not have to actually do anything with a student that is struggling. The teachers' aren't held accountable for it anymore. Now all they do is write a prescription.
