Has anyone experienced someone with mild dementia who in the course of a couple days developed severe dementia? My mother woke up one morning, was severely confused and called 911. She went to the hospital and was found to have a relatively mild UTI which she was treated for. Her confusion seemed to increase over the 2 weeks she was there so they declared her incompetent. This same scenario happened two years ago when she'd broken her ankle. She slowly improved and was able to return home on her own. I had to put her in a memory care unit this time as she keeps trying to get out but can't remember any specifics about her life. She can't understand how different she is. Wondering what could cause her to be so susceptible to this response? Even if she gets better and can function in her home again how can I send her back home knowing this can happen again?
Thus, I wonder if your Mom had a fall or did something to bump her head?
You cannot be assured that this will either go away, nor that it cannot return. A return to home may not be safe unless there is marked improvement. As to whether, if she DOES improve markedly, a return to home is possible it would depend on at least daily followup and assessment.
And as to the why, oh we wish we knew. Her doc is the best one to give you a clue as to the perhaps this and perhaps that. But keep the urine tests coming regularly. They are now very resistant to cure, and can return in a flash.
