What other REM sleep disorders are there besides REM Behavioral Disorder?
I’ve been from doctor to doctor and we’re still working on what on Earth is wrong with me – I’m having increased fatigue, by now it can be called exhaustion. I can’t concentrate, at times I can barely lift my arms or walk, and sometimes I find myself slurring my words I’m so tired. I had a sleep study done and they found that I have more REM sleep than normal and the onset is much quicker. Rather than having increasing time periods of REM sleep, mine are uniform and last a long time. My sleep specialist has ruled out narcolepsy because the onset is not severe enough, but says that the information indicates only that I am very tired, though of course this is something to continue looking into. I literally need 15 hours of sleep in a 24 hour period to function properly, while only a couple years ago I needed about 7. When I search around online for sleep disorders having to do with REM, the only thing that I find is REM Behavioral Disorder, having to do with a lack of REM, and as a result acting out the dream. I do not have that.
What other disorders are there that either result in exhaustion and an increase in REM sleep or just the latter?
