Ratski's right... sleep apnea is a huge problem and very dangerous for sudden death while sleeping. This was likely a significant contributing factor in the death of the "Minister of Defense," for those of you NFL fans who might recognize that nickname.
My problem was always not being able to convince them to go for the testing, or those who did, couldn't get them to wear their sleep apparatus. Had several patients die in their sleep that I am convinced this was a factor.
Not only was it a contributing factor, I believe that "Sleep Apnea" is actually listed as his Cause of Death on the Death Certificate.
As to wearing their sleep apparatus, the Oral Appliance is a first line alternative to CPAP.
