I was diagnosed with SOSA (among other pulmonary problems) when I ended up in the hospital near death. Not only was I falling asleep at my desk, I was also getting carbon dioxyde poisoning nearly every night and I lost about 2 years of memory due to that. I had my sleep study done after I was discharged from the hospital to confirm the diagnosis.

I guess it shouldn't have been that much of a surprise since my father, mother, and brother all had/have SOSA.
