I believe it is wrong. After initial diagnosis of UTI we believed she would receive a sufficient dose of antibiotics and return to normal. She was given 5 days of treatment and put on Zoloft. She does not seem to be handling the Zoloft well as she is still experiencing confusion and some hallucinations. I believe she should be off of Zoloft and given time to heal from the UTI without possibly have side effects from Zoloft, which in the elderly include confusion and hallucinations. How can I get the rest of the family to understand that possibly she just needs to be off meds and left to heal. I believe the 5 day course of antibiotics was insufficient. My daughter is a nurse and deals with this at a major Cleveland Hospital. She too feels the dosage was incorrect and possibly needed to be a day or two of IV antibiotics. Is there information somewhere to give the family to explain this condition better. They truly do not believe a UTI could cause this.
I don't believe that hallucinations are an early symptom of Alzheimer's disease. They are an early symptom of Lewy Body Dementia -- often the first recognized symptom. And, as you've discovered, they can be side effects of drugs and also part of UTI behavior.
I would not accept a diagnosis of dementia based on hallucinations alone, especially in circumstances with other possible causes of hallucinations and confusion.
But, were there other factors considered by the doctor who made that diagnosis?
Has Mom been depressed for some time? Or is the Zoloft being used for some other condition?
I would take seriously the possibility of dementia, but not come to any firm conclusions until some time passes. Be alert for other possible symptoms.

If test results are positive, sensitivity testing may be done to help make decisions about treatment.
What Affects the Test
Reasons you may not be able to have the test or why the results may not be helpful include:
Taking antibiotics or just finished taking them.
Taking water pills (diuretics) or drinking a large amount of liquid. This may dilute your urine and reduce the number of bacteria in the sample.
Taking a lot of vitamin C.
What To Think About
A urine culture done in the early stage of a urinary tract infection (UTI) may be less accurate than one that is done after the infection becomes established.
A urine culture may be done when an abnormal result from a urinalysis (such as an increased number of white blood cells) shows signs of an infection.
A urine culture may be repeated after the UTI has been treated to make sure the infection is cured.
A health professional may collect a urine sample by placing a urinary catheter into the bladder. This method is sometimes used to collect urine from a person in the hospital who is very ill or unable to provide a clean-catch sample. Using a catheter to collect a urine sample reduces the chance of getting bacteria from the skin or genital area in the urine sample, but catheter use sometimes causes a UTI.
People who have a urinary catheter in place for a long time are at high risk for developing a UTI.
To diagnose tuberculosis that has spread to the urinary tract, a special test will be done using all of the first morning urine on three separate days.
Sensitivity testing helps your doctor choose the best medicine to treat specific types of bacteria or fungus that may be causing a UTI.
Some types of bacteria or fungi may take several weeks to grow in the culture.

How long should a patient receive antibiotics for?
The optimal length of treatment for symptomatic cUTI has not been extensively studied. As there are many different causes of underlying abnormality, a simple recommendation cannot be made. Most clinical trials have evaluated 7–14 days of treatment, but a recent randomized multicentre study demonstrated that levofloxacin for 5 days was non-inferior to ciprofloxacin for 10 days in cUTI and acute pyelonephritis.31 Ten to fourteen days of antibiotics are usually recommended for patients with bacteraemia, hypotension and other signs of severe sepsis, whereas a 7 day regimen should suffice for those with a lower UTI.3 A 3 day course is usually not sufficient and is thus not recommended for cUTI.32 Clinical improvement should occur within 24–48 h after starting treatment. If the patient has not responded, the choice of antibiotic should be reviewed in the light of the culture results. They may need an urgent investigation to exclude an abscess that needs drainage. A patient can be switched to an oral agent when they are clinically improved providing they can tolerate it and the organism is susceptible.
