Hi,
Yes these events can cause sleep fragmentation. Yes you may not be able to visualize on a standard EEG montage the arousal. But, if you have the ability to record a cardiotach or line graph representation of the R to R value from the EKG, you will be able to see the increase in heart rate when the event culminates. This is another way of validating these events as significant.
Good luck,
Mark.
