Went to visit Dad at his NH. He was sleeping in his wheelchair. This isn't uncommon, but I couldn't get him to wake up. Nothing worked. I shook him, poked him and called his name. Finally he woke up. His speech was garbled, but he did answer simple questions. Back to sleep over and over. I had the nurse come check his vitals. BP was good, temp just a little under normal and his chest was clear. He's on pudding thickness pureed food and his liquid has to be taken with a spoon. He also has blockage of his carotid artery 70 to 90 percent. He also has hand tremors. Mostly his right hand. The blockage is on the right side but affected his left side. He had a slight stroke almost 2 years ago. At almost 97 there really isn't much that can be done with him, but I want to make sure that he is comfortable. His doc came yesterday and he was alert. She ordered blood work. I'm wondering if he's having TIAs or possibly dehydrated. He's not very verbal at times and sometimes he makes up a word if he can't remember what word to use. Just wondering if anyone else has had these symptoms with a Dementia patient.
