How urinary tract infections can trigger delirium and worsen dementia

Although urinary tract infections (UTIs) are typically minor—albeit painful—health issues for most people, they can pose serious risks for older adults, particularly those with Alzheimer's disease and other forms of dementia. In older patients, a common UTI can trigger delirium, a medical emergency marked by sudden confusion and altered awareness. This condition can not only accelerate cognitive decline but is often mistaken for an underlying neurological condition—delaying proper diagnosis and treatment.
