I'm very sorry to hear that all of this is going on with your mother! I think that the most likely cause of your mother's decline is actually her urinary tract infection. In elderly patients, it is common for an acute illness
, such as a urine infection, to trigger something called "delirium" which is an alteration in cognitive functioning which can include symptoms like hallucinations and waxing and waning levels of alertness.
Your mother is even more at risk of developing delirium because of her underlying dementia.
What I would suggest that you do is mention this concern of yours to the doctors taking care of your mother. If she is hospitalized right now, that could be her primary team of inpatient doctors. If she is at home, it could be her primary care doctor
. She should definitely undergo a formal evaluation to determine if this likely to be delirium - or, if not, what might be the cause of her decline.
Delirium can last for days to weeks, depending on the severity of the illness. Often it can be treated with redirection and reorientation, although sometimes medications may be necessary, especially if there is a lot of agitation. Again, please discuss this issue with her doctors. Good luck.
