SLEEP DISORDER: During rem sleep, your study should demonstrate no extraneous muscle motion, and if activity was present in other muscles, you could possess narcolepsy. However, active movements during sleep could be consistent with plms, a form of nocturnal myoclonus, or possibly, a full blown rem sleep disorder, which may or may not precede parkinson's. Spend some time with a neurologist and discuss.

Depends : You can have some muscle activity during rem sleep. This is something you'll want to discuss with a sleep specialist. It sounds like you already read about rem sleep behavior disorder and the neurodegenerative conditions associated with it. It's worth seeing a sleep doc.

Contributing factors: Rem atonia should occur but phasic twitches noted on sleep study should not give you a presumptive diagnosis of rbd. There are a number of other factors. Rbd is also exceedingly rare in young women. Many factors need to be reviewed by your history and sleep study. See a sleep specialist if you have not done so already that is familiar with parasomnia.
