"People that were highly functional and have low interpersonal abilities were just regarded as different now they have something that needs examination and limitations."
The following is speculation - I have no medical/psychiatric training.
Given:
ADHD is a relativly modern diagnosis - did not exist in my childhood/youth. If it did, you were considered a tad strange, bit of a personality, on a diffrent planet, etc but generally accepted as being part of the broad spectrum of human behavior. Sure there were "bad" kids who likly need a more empathetic approach than flogging but most of them seemed to "make their way" eventually.
Seems to be on the rise - why?
The accompanying rise in the use of medications that users are likly to become dependent on. May have a long term negative impact on the user.
I agree with the observation that there is no such thing as a monochrom "normal" human being - we all exhibit a range of behaviours that I am sure can be plotted on a Bell Curve (BC) demonstrating that at some times/situations, we may stray from the central "normal" range of behaviour and a few unfortunates, permanently on the lower slopes, must "live" and manage their lives somehow.
I accept that people who exhibit traits that are at the extremes of the BC may need some chemical assistance, to function in society and on what I hope is rare occasions, this may require lifelong usage.
I speculate, that the apparent pandemic (if true) in ADHD (& other personality disorders) is as much a fashion statement, brought on by the media and parental anxiety, as anything else.
I lived for much of my youth in Ireland and later England - eccentricity (difference in social interaction & presentation) was celebrated (to a point). It seems Australians are far less tolerant, seeming to seek a bland adherence to "the norm" .
I suspect that most of those diagnosed with ADHD & similar, would eventually find their own way in life, without recourse to medications, special behavioural interventions, etc, just like everyone else.
