Hi, @pamela51 - welcome to Mayo Clinic Connect. I have no personal experience with REM sleep behavior disorder, but I have heard a neurologist talk about some of the behaviors prompted by this disorder.

Here is some Mayo Clinic information on RBD you may be interested in: https://www.mayoclinic.org/diseases-conditions/rem-sleep-behavior-disorder/symptoms-causes/syc-20352920

I'd also like to introduce you to @hopeful33250 @jenniferhunter and @johnbishop.

How was this disorder first discovered in your husband?
