ADHD wasn't discovered yesterday

During one of Aspie teen's university studies he came across some confronting claims from a lecturer who stated that ADHD was a 'created label' rather than a recognised condition.
This was apparently seen as permission to the other students to vent their spleen at all the kids with ADHD who'd had the gall to cross their path; some claimed ADHD stood for Apparent Death of Hard Discipline, spouting recommendations for a length of garden hose or bamboo to sort the kids out instead of medication and therapy, with almost all of them stating there had never, ever been a kid with ADHD in their class/school when they were kids.
Others claimed it was an alternative form of controlling students in the age of not using the cane, others still stated they believed it was lazy parents unwilling to teach children social boundaries while another claimed it was older parents lacking the energy to stick to routines and discipline. Still another suggested the label had been invented to absolve the teacher and education system of any responsibility when children didn't conform to the accepted rules of the classroom.
Who knew so many people could turn rabid at the mention of a medically diagnosed and recognised condition?!
These were people who were possibly going to become teachers.
Amazingly the lecturer stated ADHD hadn't existed 50 years ago which many tended to believe and agree with.
Yet the behaviour was noted as far back as 1848 (possibly even earlier in 1798) and given further medical details and diagnosis from 1902 onwards.
Yet some in the education system insist on treating those with ASD, ADHD and other medically diagnosed and recognised learning disorders as nothing more than a stubborn child who refuses to do as he/she is told.
And it's little wonder when that belief was encouraged by one lecturer, at least.
Ironically, they are very inattentive to a condition that commonly causes inattention.
Perhaps there's a few more adults who are undiagnosed....?
