BACKGROUND: Urinary anticholinergic (AC) medications are commonly prescribed for Overactive Bladder (OAB) syndrome. Although recent studies suggest a potential link between their use and an increased risk of dementia, this association remains debated.
METHODS: We conducted a systematic review and meta-analysis to evaluate the risk of dementia in patients receiving AC treatment for OAB syndrome. A comprehensive search of PubMed, Embase, and Cochrane databases was performed. Outcomes of interest included dementia risk and its association with age, sex distribution, treatment duration, and follow-up length. Two subgroup analyses were assessed: (1) AC vs. no drug therapy and (2) AC vs. mirabegron, a beta-3 agonist and current standard of care for OAB syndrome. Relative risk (RR) with p-value < 0.05 was considered statistically significant.
RESULTS: Eight studies were included, comprising a total of 3,656,686 patients diagnosed with OAB syndrome, of whom 44.7% were exposed to urinary AC. The comparison between AC and no drug therapy showed a statistically significant higher risk of dementia in the exposed group (RR 1.2, 95% CI [1.09-1.32], I²=96%, p < 0.01). When the AC group was compared to patients who received Mirabegron, the AC use also presented a statistically significant increase in dementia risk (RR 1.28; 95% CI [1.03-1.58], I²=98%, p = 0.02).
CONCLUSIONS: Patients who received urinary AC therapy for OAB syndrome were associated with an increased risk of dementia compared to both no drug therapy and medical therapy with mirabegron. These findings suggest that, for the long-term treatment of adult patients with OAB syndrome, alternative therapeutic options to AC should be considered, with Mirabegron emerging as a valid choice in clinical decision-making.
