Mum is going downhill, she had a bad fall which she recovered from but now is very sleepy all the time and hardly eating or drinking much unless prompted, she says she aches all over, but when her Doctor checked her out she was ok, she only stayed a few minutes and I didnt get the chance to ask what I needed to, like tell her how she nearly falls over and gets so out of breathe and her heart pounds after a short walk, and how twice she has gone into such a deep sleep that I couldent wake her for ages and thought she was in a coma, is this usual for alzheimers patients to sleep so deeply?,I am very worried that she will have to go to hospital, as she is very fearful of the places, does the deep sleeping mean that she has not long to go?I am so worried that I am not doing all I should be for her.
