Urinary Tract Infection (UTI)

A UTI is the most common cause of quick onset confusion in the elderly – seems strange, but it’s true. UTIs frequently go untreated as the elderly might not report symptoms that a younger person with a UTI would have.
Typical symptoms of a UTI include: a frequent need to urinate, burning or sharp pain on urination, and a feeling that one needs to urinate all the time.
If your elderly friend has become confused at a rapid rate, get him or her to a doctor. A course of antibiotics might well reduce the dementia and return them to their previous cognitive state.
