[Theory] Is ADHD just a euphemism for retardation?

[kathisterima]

i guess it's more overengineering than meaningless

person cannot function due to inability to focus. solution = give perfomance enchancing drugs and tell them to get a good night sleep, eat healthy and exercise 

do we need a whole field of study and special labels for this?

can you be direct, what is your argument, that ADHD is a meaningless term and all people who struggle to function regardless of the cause need to hop on meds? I think you need to read that article again.
