Ryan's Sleep Study

My husband Ryan has suffered from an unusual sleep disturbance for many years.  Since we've been married I have noticed a pattern and have been very concerned about him . We have done lots of research and we suspect he has RBD or REM Sleep Behavior Disorder. During his dreams when his body should be paralyzed, something in his brain isn't working like it should and he begins to physically act out his dreams. It’s possible it could be caused by a brain injury he had when he was a child . He does everything from flying off the bed, kicking,  climbing, flailing about in every direction and screaming.  He has lifted up our mattress many times and tried pushing the entire bed over. He has climbed over our head board. He has even tried to go out the window and he has woken himself up standing at the door attempting to go outside.  He has pushed everything off of the nightstands , broken things and ripped blinds out of the windows. This happens up to 4-5 times a night almost 7 nights a week.  Which can be miserable for him and I both. 
We have tried everything over the past couple years from a weighted “anxiety”blanket, Melatonin (every kind),  other OTC sleep aides, calming essential oils, soothing sounds,  and LOTS scriptures and prayers!!
He has injured himself several times by getting his leg or arm caught under something or twisted his ankle during these episodes. He has also unintentionally injured me. Ryan is the most loving and amazing husband who always does his best to make me feel loved and secure, but during these episodes he just has no control of his actions.It has been really exhausting and draining on both of us. I can't remember the last night we got a full nights sleep. This has had a huge impact on both our physical and mental health.  I go through most days in a fog and extremely fatigued from lack of rest . As we all know it is so important for your body to heal and function properly. 
He was on a waiting list for 2 months and we finally got an appointment with a sleep neurologist at Scott & White Hospital in Temple a couple weeks ago. They want to do an overnight sleep study this week to evaluate him and then we will determine the next steps. However, we were told his insurance has denied to pay for a part of the sleep study called a Multiple Sleep Latency Test. The Dr recommends this type of test to rule out some other possible conditions.
If you know my husband you know he is an extremely hard worker and always loves helping others! Right now we just don't have the extra money to pay towards the testing.  If you feel led in your heart to give we could really use some financial help to get this sleep test and try to get some answers for him. Thank you for taking the time to read this and if you choose to give we are eternally thankful! If you can’t give just send some prayers our way for healing and favor with the medical staff for his testing and a plan of treatment!
