Getting weaker in mind and body

She doesn't get up much at all. When she does she isn't very sturdy walking. I've tried to get her to use a walker, but she doesn't want to. I'll try to get Les to talk her into it. She get's confused at times and can't remember what she is to do, like going to bed or when it's time to eat, and what to do, like if she has pancakes, she forgets that she needs to put on butter and syrup and cut them up. She just looks at them confused and asked what to do. The back of her head seems to be hurting more but says it isn't enough to take more meds yet. This doesn't mean she won't be better next week. She always seems to bounce back.
