When I was a kid back in the seventies ADHD as we know it now did not exist. Sure there were probably kids in my classroom who had this disorder but we just didn't have the diagnosis or the name for it. This is much akin to the fact that I didn't know people with autism existed until I wa...



If 'defect of moral control' were still the defining term, I should think that most of us suffer the disorder.
The truth is, acronyms drive me crazy unless I need to type out the term in full, ten times in an article, then they make perfect sense to me.

Not that, in my particular case, it was at fault, rather I just can't remember them all.

There exists a shadow world, many worlds, actually, of which we as a people remain ignorant. How to educate ourselves when our insular world contains no reference point. Even the terminology changes. Understanding and tolerance don't come cheap, paid for by those who suffer daily slights. Those would be never ending but for people like you, who write; one day what lies behind the acronym will be finally understood.
But there will always be people who fear something different, whose reaction is to hurt and insult. We just need to make them the outcast, with their own acronym.
