I would be remiss not to mention all the research that indicates RBD is often a precursor to the development of neurodegenerative diseases, such as Parkinson's Disease and Lewy Body Dementia. It was a great concern when my Dad received his diagnosis of RBD. But because of this, my Dad is evaluated annually by a neurologist. We have been so fortunate that so far, so good! It is imperative that people with RBD be routinely evaluated for signs of developing other problems.
