Family history of idiopathic REM behavior disorder
TLDR
Increased odds of proxy-reported family history of presumed RBD among individuals with confirmed iRBD are found, suggesting the possibility of a genetic contribution to RBD.
Chronic behavioral disorders of human REM sleep: a new category of parasomnia.
TLDR
These REM sleep neurobehavioral disorders constitute another category of parasomnia, replicate findings from 21 years ago in cats receiving pontine tegmental lesions, and offer additional perspectives on human behavior, neurophysiology, pharmacology, and dream phenomenology.
Delayed emergence of a parkinsonian disorder or dementia in 81% of older males initially diagnosed with idiopathic REM sleep behavior disorder (RBD): 16 year update on a previously reported series
TLDR
The vast majority of men P50 years old initially diagnosed with iRBD in this study eventually developed a parkinsonian disorder/dementia, often after a prolonged interval from onset of iR BD, with the mean interval being 14 years while the range extended to 29 years.
