A few times a month I have a dream enactment
I saw a neurologist who specializes in sleep disorders for this about 3 months ago and I had a sleep study done in late November. According to the study, I slept for 5 hours and 13 minutes and my sleep was normal. I have dream enactment episodes that I'm aware of only a few times a month though. Is it possible that the study was just done on a night where I had no dream enactment? Or if I did have REM sleep behavior disorder, would something abnormal definitely have shown up in the 5 hours, 13 min? I'm wondering if I should get a second sleep study done.
I should add that my father and uncle both developed spinocerebellar ataxia at around age 50, although I do not have any symptoms of SCA or any other neurological disorder as far as I know. I believe my father had RBD too.
For now is not necessary to repeat the sleep study.
Hello again and thanks for being part of the "Ask a Doctor " service.
I have read your query and here is my advice.
Since your sleep study (polysomnography) didn't show any problems, in my opinion, it is pointless to repeat it.
RBD is a condition that worsens with time and become more frequent, so, since you don't report any worsening, RBD is not suspected.
In the other hand, increased muscles tone during sleep study, is one of the diagnostic criteria for RBD, so, it's not your case.
Neurological degenerative diseases result in other symptoms, besides RBD, so, I don't think yours is a case of SCA.
Your sleeping and dreams disturbances may be linked to antidepressants use, or increased stress levels.
I think that you should be reevaluated with a sleep study if there will be any worsening or increase in frequency of your symptoms.
Hope you found the answer helpful.
Let me know if I can assist you further.
Your message definitely did help me but I'm still worried I could be beginning to develop RBD.
The report of the sleep study is necessary.
Muscles tone is one of the aspects that a sleep study should evaluate, especially in cases of RDB suspicion.
I don't know what to say if there was such an evaluation or not, but the report should give the necessary information.
If in doubt, then I think, a new sleep study should be considered.
Hope this helps.
Feel free to discuss with me if you have further questions.
