I personally believe that "normal", when it comes to people's behavior, social interactions, and the way their mind works, is a completely broken idea. All of these attributes are completely fluid, depending on the when, where and who with you happen to be.
On that premise, the whole idea of neuro-divergence and the idea that you can classify people in arbitrary categories such as ADHD, Autism, etc ... and that this classification will lead to a way to "fix them" is complete and utter BS.
An interesting fact is that caffeine will often affect the "ADHD mind" differently. It's been reported to have no effect, or have very limited effect, or make people even sleepy, but almost always something non-standard. Once, in high school, without the supervision of my parents, I drank maybe 2 red bulls and 2 cups of coffee, 1 black. I remember feeling disappointed it didn't work, and I didn't feel any rush of energy.
I'm simply saying that the way we're classifying people is utter BS, and assigning labels is very hurtful
Everyone is different. The "median man" does not exist. Or if he does there are maybe 3 on the whole planet, not something significant.
Much like your fingerprints, your brain is completely unique, and what chemicals / lifestyle / circumstances affect it in what way is a hugely personal affair. And to make matters even more complicated, it changes very much over time.
If you agree to let any kind of random bozo, with a so-called specialist title and a diploma tell you that you are a "typical neuro-divergent belong to class XYZ", run like hell.
The only way is to experiment with the way your mind works: chemicals, social groups, type of work, meditation, yoga, sports, more or less social interaction, whatever ultimately gets you to where you want to be.
But if you let every other snake oil salesman out there, or the rest of humanity in general, tell you who you are and who you ought to be ... good luck to you.
