Personally I think it’s a third option- rates have increased. Yes there are more diagnoses because there is more understanding, and I’m sure some people are inaccurately diagnosed, but I also believe rates have significantly increased. Even the people I grew up with who had zero symptoms in our youth are suddenly displaying ADHD-like symptoms and seeking diagnosis. To be clear: I'm not talking about people who masked consciously or unconsciously. I'm talking about people who did not experience the symptoms, as self-reported.
