>In your case, you are not aware of the causes for your neurodevelopmental differences, but that doesn't mean they don't exist, and they exist regardless of your opinion.

That is as empty a statement as "every effect has a cause". Yes of course there are genetic, social and environmental causes for my developmental differences. I don't deny that at all. However, everything about the way we develop is multifactorial whether you turn out normal or not. It's wrong to say there are causes for my ADHD as if they were different from the same causes that make people develop normally. If that's what you mean, I 100% agree with you.

However, I want to be clear. I believe that it is inaccurate to say that there is a "cause" for ADHD in the sense that a virus is a "cause" for respiratory illness. This is what people hear when we say there are things that cause ADHD.

ADHD is not a monolith. There can be ADHD with a probable cause (your case), ADHD that is caused by a delay in brain development (kid who eventually grows out of ADHD), ADHD secondary to physical trauma as a child, ADHD that is "caused" by a brain that is just meant to be structurally different in its mature state. I would say that the first and third scenarios I describe to have "causes" for ADHD. The other two I wouldn't say there are causes. This is what I was referring to when I say there is not well defined data to describe what is more common.

I am in no way denying that people with ADHD have difficulties and that there are compensatory strategies to mitigate those difficulties.
