Ask HN: Is ADHD Real?

That's a pretty useless response when the entire premise is that you have no idea whether the task is simple or difficult. It really only makes sense when you already kind of understand the ease or difficulty of the task, at which point the response is kind of redundant. It would've been a lot more helpful if he'd said something more like, "This requires professional expertise, it's not something laymen can do." That would actually give you useful context.

Imagine how silly this exchange would sound when talking to a car mechanic regarding routine maintenance: "Are there any tools I can use to replace/jump-start/whatever my car battery?" "Would you want a mechanic messing with your code?" Uh, no, but the answer to the first question is "yes" nevertheless...

I’m slightly confused that person who provided you with diagnosis didn’t provide you with overview of how ADHD works.

I highly recommend you treat it as an actual disorder because the sooner you address it, the less it will affect important parts of your life, especially your relationships.

Asking how it is measured, what kind of effect it has, whether the effects are meaningful, how it can be explained, whether there are more appropriate labels, what kind of alternative explanations exist, etc.

Asking whether something is "real" fails even when talking about fundamental physical phenomena like gravity, math or consciousness. So, this is almost always the wrong question.
