I've always been a cautious skeptic of ADHD in children. On the one hand I know ADHD is a thing and that it legitimately affects some children, but on the other hand I realize that alot of ADHD symptoms overlap with the general nature of children, especially boys. My wonder is when does it to go from a kid just being a kid to a child actually affected by ADHD. Often times it's described as just not being able to pay…
ADHD is not just labelling children with being disordered for being children. It’s labelling like the most inattentive, dysregulated, and hyperactive 5% or so of children. Children that act like 5 year olds when their peers act like 7 year olds. ADHD has been observed for centuries as well. ADHD in women tends to be diagnosed later in life and if you study certain subpopulations of women like teen mothers you will trip over ADHD and the diagnostic gap narrows with age.
There’s also evidence like.. from the OP where we can observe neurological differences. I think my main problem with ADHD is labelling something that’s probably evolutionarily adaptive (People with ADHD love having unprotected sex early in life) as a disorder and deficit, but this gets into the philosophy of medicine.
Dr. Russell Barkley is a good source of information and champion of the scientific mainstream view of ADHD.
