Why UTIs in Older Adults Often Go Undetected Until It's Too Late

Urinary tract infections (UTIs) are a widespread health issue among older adults, particularly those with dementia. These infections rank as the second most common type in this age group, often leading to hospital stays and complications. Detecting them early can be difficult, especially when symptoms are unclear or absent.

Between 5% and 12.8% of older adults experience UTIs, making them a frequent medical concern. In 2016, US data showed that over 551 out of every 100,000 adults aged 65 and above were hospitalised for these infections. They accounted for roughly a quarter of all hospital admissions in this population.

Older adults, with or without dementia, may not show the usual signs of a UTI, such as pain or fever. Instead, symptoms can appear as confusion, behavioural changes, or even hallucinations. This makes diagnosis harder, particularly for those with dementia who struggle to communicate their discomfort. When symptoms *are* present, antibiotics remain the standard treatment. However, doctors only prescribe them in confirmed cases to avoid unnecessary use. Left untreated, UTIs can escalate into serious conditions, including kidney failure.

UTIs pose a significant risk to older adults, often going unnoticed until they become severe. Early recognition of unusual symptoms—like sudden confusion or difficulty urinating—can help prevent hospitalisations and long-term damage. Proper diagnosis and careful antibiotic use remain key to managing these infections effectively.
