Hello everyone; I am new to this site but I have learned quite a bit and can relate to many of the scenarios that have been presented. My Dad was diagnosed with Parkinson's Disease about eight years ago. About two years later, his diagnosis was changed to Lewy Body Dementia. He has been taking Levodopa from then until now. My question is: does anyone know about severe breathing difficulties relating to LBD? He has been struggling with his breathing daily, for about a year. We actually took him to the Emergency Department on several occasions. They said each time, that they could not give him oxygen because his oxygen saturation was always between 98% and 100%. Still, even doing something as simple as bending down to wash his face in the sink, brings about severe breathing difficulties, where he feels as if his entire respiratory system is being cut off. I'm wondering if anyone has ever heard of this.
