I beleive that cetaplexy is a long-term symptom of this disease. I've had Narcolepsy since approx. 2009; however, I didn't begin to develop cataplexy symptoms until about 2020.
I've taken a few nasty falls by just simply turning tand ore a few ligaments in the process. It took some time to heal as well- i've been using a cane ever since. I don't know when it's going to happen again!
