I see ADHD meds constantly being prescribed to people that fit ADHD symptoms; but neurotransmitter levels usually aren’t checked prior, which could cause some issues in development. Capitalism is a parasite that values profit over people, so it is unsurprising to find that some people fit ADHD symptoms because the brutality of capitalism exhausted them.
Artificially inserting neurotransmitters into children can affect their development; health issues could appear as a result.
I also have ADHD and don’t take any meds.
Some people do grow out of it. Some people figure out a mechanism how to stay focused.
