Lower Urinary Tract Symptoms Associated With Poorer Cognition in Older Adults

Lower urinary tract symptoms were significantly associated with lower scores on measures of cognitive impairment in older adults, based on data from approximately 10,000 individuals.

“We know that lower urinary tract symptoms are very common in aging men and women;” however, older adults often underreport symptoms and avoid seeking treatment, Belinda Williams, MD, of the University of Alabama, Birmingham, said in a presentation at the annual meeting of the American Geriatrics Society.

“Evidence also shows us that the incidence of lower urinary tract symptoms (LUTS) is higher in patients with dementia,” she said. However, the association between cognitive impairment and LUTS has not been well studied, she said.

To address this knowledge gap, Dr. Williams and colleagues reviewed data from older adults with and without LUTS who were enrolled in the REasons for Geographic and Racial Differences in Stroke (REGARDS) study, a cohort study including 30,239 Black or White adults aged 45 years and older who completed telephone or in-home assessments in 2003-2007 and in 2013-2017.

The study population included 6062 women and 4438 men who responded to questionnaires about LUTS and completed several cognitive tests via telephone in 2019-2010. The tests evaluated verbal fluency, executive function, and memory, and included the Six-Item Screener, Animal Naming, Letter F naming, and word list learning; lower scores indicated poorer cognitive performance.

Participants who met the criteria for LUTS were categorized as having mild, moderate, or severe symptoms.

The researchers controlled for age, race, education, income, and urban/rural setting in a multivariate analysis. The mean ages of the women and men were 69 years and 63 years, respectively; 41% and 32% were Black, 59% and 68% were White.

Overall, 70% of women and 62% of men reported LUTS; 6.2% and 8.2%, respectively, met criteria for cognitive impairment. The association between cognitive impairment and LUTS was statistically significant for all specific tests (P < .01), but not for the global cognitive domain tests.

Black men were more likely to report LUTS than White men, but LUTS reports were similar between Black and White women.

Moderate LUTS was the most common degree of severity for men and women (54% and 64%, respectively).

The most common symptom overall was pre-toilet leakage (urge urinary incontinence), reported by 94% of women and 91% of men. The next most common symptoms for men and women were nocturia and urgency.

“We found that, across the board, in all the cognitive tests, LUTS were associated with lower cognitive test scores,” Dr. Williams said in her presentation. Little differences were seen on the Six-Item Screener, she noted, but when they further analyzed the data using scores lower than 4 to indicate cognitive impairment, they found significant association with LUTS, she said.

The results showing that the presence of LUTS was consistently associated with lower cognitive test scores of verbal fluency, executive function, and memory, are applicable in clinical practice, Dr. Williams said in her presentation.

“Recognizing the subtle changes in cognition among older adults with LUTS may impact treatment decisions,” she said. “For example, we can encourage and advise our patients to be physically and cognitively active and to avoid anticholinergic medications.”

Next steps for research include analyzing longitudinal changes in cognition among participants with and without LUTS, said Dr. Williams.

During a question-and-answer session, Dr. Williams agreed with a comment that incorporating cognitive screening strategies in to LUTS clinical pathways might be helpful, such as conducting a baseline Montreal Cognitive Assessment Test (MoCA) in patients with LUTS. “Periodic repeat MoCAs thereafter can help assess decline in cognition,” she said.

The study was supported by the National Institutes of Neurological Disorders and Stroke and the National Institute on Aging. The researchers had no financial conflicts to disclose.
