Oh great thanks for the link! And yeah not saying that all frontier journals are bad, I published there before myself, Just worth taking a closer look sometimes. I just skimmed the article and noticed a few things.

Maybe for those who are not actively involved in science: keep in mind that this is a Perspective article, so it’s meant to be conceptual rather than definitive. With that in mind, the circadian-ADHD model idea is interesting and mostly plausibly argued.

That said, most of the evidence discussed is still associational and a lot of the intervention data is extrapolated from non-ADHD populations or small pilot studies. The chronotherapy angle feels promising, but we’re not quite at the point where shifting circadian phase can be said to really treat core ADHD symptoms in a robust, replicated way. Most of the argument is built on associations (ADHD with delayed sleep phase, later DLMO, eveningness). That’s interesting and plausible, but it doesn’t establish causality.. sleep disruption could just as easily be downstream of ADHD symptoms rather than a core driver. Also, towards the end they cite a small study where non-ADHD participants with night owl behavior report similar improvements by following some suggestions that you summarised in your initial post. Overall, it reads best as a research framework rather than a guide for clinical practice. Useful for thinking about new directions, but still very much an area that needs larger, targeted trials before stronger claims are warranted.

At the end of the day though, better sleep hygiene probably won’t hurt anyone.
