I don't disagree but the way they describe it sounds more like an autistic nightmare. I don't know ADHD to be commonly associated with sensory issues and social cues and that hasn't been my direct experience with it. I've had issues with social cues but I've found it easier to pick up on them when I had peers to practice with that weren't put off by my adhd.
Also I don't know that I would be focused if they just gave me a job because of the whole adhd thing. I'm certainly not significantly better than anyone else in the building at my current job...
There is a huge overlap between the two conditions. Probably far more behaviours in common than exclusive. We think of them as separate as a matter of convenience e.g. to administer healthcare, etc, but there is no precise scientifically reliable definition for either. It's like saying someone is white or black, superficially the difference is obvious but when we look closely we cannot define what we mean by those words with universally repeatable measurements.
Sure, but what's described in the post is very much in line with very common descriptions of things autistic people struggle with - so much so that it's basically in the definition of the diagnose - and it's not something that is typically (or ever) being ascribed to ADHD.
Just because these spectrums are related and interwoven (together with other ones as well) in mysterious ways we don't yet understand, we don't need to treat them as one. Especially as laymen. They are separate diagnoses with different definitions. By, as laymen in a social forum where people often times go before even considering going to get evaluated, cross-ascribing symptoms between diagnoses we risk steering people in the wrong direction and they could potentially waste years thinking they have a diagnosis they don't have (according to our current health care systems).
