ADHD makes it nearly impossible to write large sums of text without being distracted and forgetting what you were doing.

Pardon me for being pedantic, but I'd at least like to point out that, as someone with ADD (which is basically ADHD without the hyperactivity), writing large amounts of text isn't as impossible as you seem to be making it out to be. Sure, I do get distracted while writing a long response to something and my mind definitely wanders, but I'd hardly call it [i]impossible[/i]. Just takes me a lot longer to write one than if I were on my meds. 

In fact, if anything, I'd say it's quite possible that my ADD causes me to write [i]longer[/i] responses, actually, since due to that I often repeat myself and make the same point over and over, sort of rambling. Basically, it makes it harder to be concise, which makes sense. 

I'm not going to argue with you about how it does seem unlikely that one person could have all these - honestly it struck me as unlikely, too - but at least consider the fact that just because he has any one of these disorders doesn't mean he has the most [i]severe[/i] case of a disorder. If my ADD was more severe, would I fit your description? Maybe. And while mine isn't [i]that[/i] bad, it's still present enough that I have a diagnosis for it and meds that I take - although I don't even take them every day. I'm not even on them right now. :/
