I'm hoping someone can give me some help about the following - or at least reassure me I'm not alone! My mother is 74 yrs old. She has suffered from repeated urine infections for several years. Usually the main (and often only) symptom is that she is confused - she doesn't think she is at home and constantly tries to get out of the house by banging on doors and windows, day and night. In the last 3 months she has had 5 courses of antibiotics. The confusion stops while she is on the tablets but about 3 - 4 days after a course has finished she starts the cycle again, trying to get out of the house and not understanding me when I tell her she is home or it's the middle of the night. Last week she ended a course of antibiotics and the doctor gave her a low dose to take just once a night for a longer period. Today, however, three days after taking the higher dose, she is again trying to get out of the house, thinking she isn't at home. I do not understand why she is fine when she is taking the antibiotics (in fact she is like a different person) but a few days after stopping she begins to be confused again. We have been back to the doctors so many times and she has seen three different doctors in our practice. Can anyone shed any light on whether the lower dose of antibiotics will eventually 'kick in' and help prevent any more attacks. Or should I be worried that it is a dementia type illness she has, even though she is fine mentally when on the antibiotics? I think the Doctor should be referring her but don't know if he is reluctant because of her age. Thanks in advance.
