lol neither of the studies you quoted are researching the rates of ADHD, like at all. The one study is a narrative review and the other I couldn’t get into but on mobile.
This was literally just setting the stage for their hypothesis…
You would need to find a meta-analysis or systemic review of current research. The article you are quoting is just framing the paper around 15%.
In this narrative review we search the extant literature and discussed a brief overview of the aetiology and prevalence of NDEBID, enumerate common problems associated with current classification systems and provide recommendations for a more integrated approach to the nosology and clinical care of these related conditions.
Also, quoting a single study and framing your world view based on one study is absolutely not science, but have at it…
None of what you said explains what they are talking about lol.
It’s like you have no experience with what they’re talking about
