Yesterday I was unable to wake my husband. I tried to wake him at 6am, 7am, 9am and then noon. He would stir slightly then fall back asleep. I called paramedics and they took him to emergency room. We later discovered that he must have fallen during the night. He had pulled tendons in his right shoulder and may have a slight fracture to his right patella. He has previously been diagnosed with parkinsons and lewy bodies dementia. He cannot remember anything about yesterday or what happended to him. He does not remember me trying to wake him or the hospital visit. Can his diseases have caused this?
