I don’t want to take away from Matés book helping you/being a good read, but they are a layman when it comes to adhd.

Dr. Russel Barkley often has videos analysing Matés opinions, which are well worth a watch (and he is great with quoting sources so free rabbit holes disappear into)

e.g.: Playlist of his Maté videos, beware youtube link

I liked it but I also felt it was a bit outdated. I’ve gone back to it a couple times but during that, admittedly scattered, time I finished Taking Charge of Adult ADHD by Dr. Barkley and then recently started How to ADHD by Jessica McCabe.

I’ll admit my opinion/openness to the book changed after I learned how effective and well-researched medication is and noticed he mentions a few times in the first few chapters how he doesn’t seem to believe the science or just disregards it.

Note: Just checked and realized Dr. Barkley’s book first came out only a year after Dr. Mate’s so I guess they’re originally not that far apart.

I can second this book. But also, I’ve not been able to finish it.
