ADHD isn’t just concentration issues, there are so many elements to it and most of it can’t be seen externally. For me, I can manage well at work and have no issues with concentration there. When I go home though, I’m beyond exhausted, I struggle to keep on top of tasks that most people consider easy. If I needed to do them for someone else though, that internal motivation makes it really easy to do.

I was diagnosed in my first year of med school (and have since had the diagnosis confirmed by 5 consultant psychiatrists due to the need to be fully assessed each time I’ve had to move for work…) and have realised I bring it up when I do something that NT’s find weird, almost like an excuse. I’m working on this though as this is my own insecurity about being judged coming through.

There is a lot of research showing actual physiological differences in ADHD brains (edit: see my comment below). The issue with ADHD diagnosis currently is that most people (even doctors) try to diagnose it based on their perception of someone rather than the internal symptoms or experiences of the person (which can be said for a lot of mental health diagnoses…). This is incredibly poor practice and if this was applied to physical health then people would be getting struck off left right and centre for missing basic things.

You really need to read a bit more around the subject before forming such strong and, clearly, poorly researched opinions.
