In 2006 my Mom was in hospital for a minor operation. She had been DX with MG just a week before but in my opinion she had it sometime before. She had neck and swallowing issues at least a year before. We took her to several neuro's and the most we got was she was de-conditioned. Anyway when they put her under for surgery when she came out she couldn't ever breathe on her own and we lost her. So I would say she died from MG but her DC says "old age"
