What Causes Vivid Bodily Movements And Sudden Waking Up During Sleep?
Please get a sleep study done.
Detailed Answer:
Hello and thanks for using HealthcareMagic.
I have read your question and understand your concerns.
Making vivid movements and waking from sleeping is one of the indications that the underlying disorder may be the REM behavior disorder ( RBD ), but a sleep study is necessary to confirm or exclude the diagnosis.
The main feature in the sleep study is the presence of the REM sleep without muscular atonia.
Also, epileptiform activity should not be present during this phase evaluated by sleep EEG.
If the diagnosis will be confirmed by the sleep study, it is true that this condition may herald the development of other neurodegenerative disorders such Parkinson's, Levy body dementia, etc. in the future, but this may happen only in about 30 % of cases with RBD according to studies.
So, basically what you read is potentially true.
Get a sleep study done and follow up with your Neurologist.
Hope you found the answer helpful.
Let me know if I can assist you further.
Take care.
