Hey, I seem to be in a similar situation now with occasional dream enactments (43m with severe sleep apnea- not overweight, have been highly adherent to CPAP for about 5 years). I had been on an antidepressant medication for about 3 months in November 2023 and had a very typical RBD dream enactment where I defended myself against some attackers and kicked in the bed violently. I woke up to my kick immediately. Luckily, my wife was not hurt, nor was she aware of what had just happened. Knowing it may have triggered this, I stopped the antidepressant rapidly with little withdrawal issues.
But for the last 6 months I have been still experiencing what might be called a milder form of dream enactments (Like kicking a football in my dream, my leg moves, though less intensely; something touches my hand in my dream, I move my hand to avoid it; I try to push my car brake to stop my car in my dream, I do the movement briefly etc.) and I wake up immediately after these relatively brief movements. I almost never sleep without my CPAP. I had a PSG study recently, I could not sleep well, though I still had some REM. Still waiting for the formal results but the sleep technician said in the morning that atonia looked okay.
I am still very anxious about RBD and its strong relationship with future neurodegenerative diseases. I was wondering how things have progressed for you. Have your occasional dream enactments dissolved or increased in frequency? Best wishes, and stay well.
