Yeah, me too. That makes me an expert, right? The fact is, I didn't even know until 5 years ago. You can make a qualified guess before asking a doctor yes, but at least here it seems a doctor has to rule out a lot of options, including sleep apnea before he they go with ADHD.
Also, as has been mentioned before, practicing d/p tend to see a few cases every year and has at least some background to say what is normal and not.
All this should be obvious, shouldn't it? It is not like anything I have written so far requires huge leaps of faith, no?
