I got caught up in this myself, I was recently(ish) diagnosed with ADHD and I was struggling with some preconceived notions of what it would be like after seeing a ton of articles, social media posts, etc that seemed to all make ADHD out to be this singular experience that I don't match up with. (Even worse I had preconceived notions of what the medication would be like, which it has been great but it wasn't quite like I was lead to believe)
I have parts of it, and that's part of why I did not even think to get diagnosed until I was in my thirties. It wasn't until I said something to my doctor casually that the conversation came up.
I think these general terms can discourage people from getting help because their experience doesn't line up with headlines like that that imply if you don't have this experience you don't have it.
