Hello TenaLouise,

I did not answer yesterday to investigate more and try to answer properly today. I don't know and it seems that searchers are investigating on that too, some finding there is a prevalence of sleep apnea in PD, some finding there is not. There *might* be something, I personally believe there is. But I don't want to tell ********. I will study this today and try to find clues. Suggestions are welcome.

Greetings
Karine
