Behavioral Changes and UTIs

Sudden, unexplained behavior changes and decreased alertness may be symptoms of a bacterial infection, especially in older adults with dementia. In fact, this is sometimes the first indication that a person has a bacterial infection.

A urinary tract infection or UTI is one bacterial infection that may precipitate behavioral changes. Bacteria entering the urinary tract through the urethra cause UTIs. Other symptoms may include a frequent, urgent need to urinate, burning upon urination, fever and cloudy or bloody urine. Antibiotics successfully treat UTIs.1‘Bacterial Infections.’ Sepsis Alliance, 12 Jan. 2021, www.sepsis.org/sepsisand/bacterial-infections,10‘Urinary Tract Infections and Dementia.’ Alzheimer’s Society, 1 Apr. 2017, www.alzheimers.org.uk/get-support/daily-living/urinary-tract-infections-utis-dementia
