Urinary tract infections (UTIs) are a common condition affecting older persons, often accompanied by cognitive decline and mental disorders such as delirium and dementia. The diagnosis of UTIs in older adults can be challenging due to symptoms like confusion, behavior change, and altered perception. Treatment involves antibiotic therapy, while management of associated mental disorders requires pharmacological and supportive therapies. To prevent UTIs, caregivers can encourage good hygiene practices, adequate hydration, and bladder training. Preventing all UTIs is impossible, but reducing the risk through these measures can be beneficial.
