For a while now my mother has been confused and hallucinating, and just a complete different person, but this only seems to be happening of a night time, she is completely fine through the day time but at night she has been thinking that everyone is after her and keeps hearing and seeing things that aren't really there, and doesn't understand or believe anyone when we try and show her that everything's okay and normal, at first we thought that it may have been some sort of dementia because all the symptoms were adding up, but her doctor had said it was just nerves. and recently she became dizzy and almost fell, so we had her admitted to hospital to get checked out by a different doctor and they say she has a UTI, so my question is, will she recover from this? Will She go back to normal? Is it just a coincidence? Could she actually have dementia? But also a UTI which doctors think is causing this?
