Last night was so hard. He "pounds on the mattress which sounds like a cannon when you are trying to get to sleep. I finally went to another bedroom and soon he came looking for me and said I want you by me...so back I went. It took a couple of hours more to fall asleep. This seems so petty but I do need my sleep! I feel it today. I found an old "white noise machine we have had for years which has different story sounds, rain, thunder, birds, wind, etc.mmi thought Imwould try that tonight but I don't want to upset him. What do you think? Does anyone else have this experience and why do they do that? The neurologist diagnosed him with atypical dementia, tells me little, could this movement be a symptom of Parkinson's? He has no tremors, just quick repetitive finger movements.
