Scottsdale Insights: Dementia and Urinary Tract Infections

Urinary tract infections, commonly referred to as UTIs, can cause discomfort and inconvenience for anyone, but for older adults, especially those living with dementia, they can present unique challenges and difficulties.

Studies suggest that UTIs don’t directly cause dementia, but there is a connection between the two. Older adults are more likely in general to get UTIs, due to a number of factors. A weakened immune system, less effective bladder function, or other health issues. These factors often also affect people with dementia.

UTIs can also lead to sudden confusion and delirium, especially in the elderly. This state of confusion may resemble, or even worsen, the symptoms of dementia. For instance, someone who is already experiencing a mild cognitive impairment might experience significant loss of memory or have an episode of disorientation while suffering from a UTI.

People with dementia may also have trouble identifying or communicating their symptoms of UTIs, such as the burning sensation or the urgent need to use the bathroom. This makes it more difficult to diagnose UTIs promptly, which delays treatment and worsens the health outcomes. Additionally, studies have shown that people with dementia are more likely to be hospitalized if they have a UTI, which can make cognitive issues worse.

Delirium is a sudden and severe state of confusion that seniors can develop. Oftentimes, it is triggered by infections, such as UTIs. Delirium comes on quickly and can be distressing both for the patient and their loved ones.

While UTIs don’t cause dementia, they can make symptoms worse or create a confusing overlap, particularly in older adults. Being vigilant about hygiene, recognizing early signs of delirium, and seeking medical evaluation promptly can help keep your older loved ones healthier and more comfortable.
