My mother lives with me and was recently diagnosed with Dementia. I know that Alzheimers can kill you but what about Dementia? She's good with long term memory but day to day or even within the space of hours, she forgets and insists that she didn't do or say what it was. She also keeps falling; could it be that she is forgetting to use her legs correctly? I know that sounds stupid but I'm just trying to figure out what else is going on. She does some strange things, yells at herself, and can't understand certain things she's told. Any help would be so appreciated.
