There are symptoms that are clearly directly caused by OSA (e.g., sleepiness) and those that can be caused by OSA (e.g., memory problems, irritability, depressive symptoms, anxiety, etc.). Then there are the consequences to our lives of long-term untreated OSA (e.g., damage to careers from poor job performance, social impairment, etc.).
Then comes treatment. There are a few ways this can go. It can go spectacularly well and all the above can be reversed (hip hip hooray!). It can reverse the direct and indirect symptoms, but there can still be the carnage of careers, family, etc. and that can take longer to repair. There can be inconsistent improvement (e.g., I'm no longer sleepy, but, while improved, my memory still isn't what it used to be). In that case, one can make sure the therapy is truly optimized. If it is, one moves on to asking if there is anything else causing the persisting problems? If no obvious other cause is found, certain lingering symptoms can always be attributed to OSA (e.g., some memory impairments in some people do not completely reverse in OSA, and this is known).
That said, IMHO, some things cannot directly or indirectly (except very tangentially, which doesn't count) be attributed to OSA. Based on nothing other than my very unscientific gut-feeling, I think depressive and anxious symptoms can be related to OSA (which doesn't mean they always ARE), but I don't think manic symptoms can be.

I don't think that "compulsive behaviors" (not my term) such as "shopping" and "gambling" can be attributed to OSA directly or indirectly. I just finished reading a book by Kay Redfield Jamison, who has bipolar disorder, and in this book she repeatedly mentioned the importance of getting sleep so she won't become manic. So in someone who has a proclivity toward bipolar disorder, certainly any sleep deprivation can be a risk factor for relapse. But in my ignorant opinion, mania is not a likely manifestation, directly or indirectly, of OSA. As far as "substance abuse", I don't think it's specific to people with OSA. If someone wanted to make the case that abuse of stimulants may be related to OSA, I'd argue that it should be just as prevalent in any other group of sleep disordered/tired people, and I'm not sure how prevalent it is anyway.
How does sleep apnea (or sleep deprivation) affect judgment?
Clearly it can affect memory and cognition. And it may cause someone to buy a few extra cans of deodorant because they can't remember they already have 4 at home (you know who you are!). But buying a BMW while unemployed, having an affair with your boss, and telling your mother in law that you can't stand her meat loaf, nah.
