Mum has Alzeimers, is 87 years old and lives with me. Over the last 3/4 days she has started coughing a lot and is always spitting into a tissue. The main problem now is that her legs are giving up and she is hardly able to walk with her frame and struggles to lift the frame to move forward. She has a carer am and pm but I'm here for the rest of the day. She just says I will be glad when I'm better. She has started doing strange things such as trying to put her cup on the table but she hasn't anything in her hand. She is not eating very much although I do her small amounts of all sorts and her drinking is not really enough either. Do I ring the doctor, or hospital as I don't want to call people unnecessarily but I don't like to see mum like this either. I do hold her from the back so she doesn't fall but she is a dead weight and don't know how long I can do this. I know the carers feel useless but I know they cannot lift her.
