AIM: Cerebral small vessel disease and lower urinary tract symptoms are common in older people. However, the association between white matter hyperintensity (WMH) and overactive bladder (OAB) is not fully understood. We aimed to identify the relationship between WMH and OAB.
METHODS: We carried out neuropsychological testing and head magnetic resonance imaging (T2-weighted and fluid-attenuated inversion recovery) of 72 outpatients at a memory clinic and evaluated their Overactive Bladder Symptom Score. WMH was assessed using the Fazekas scale, and WMH volumes were determined using Software for Neuro-Image Processing in Experimental Research. OAB was diagnosed based on a urinary urgency score (the third question of the Overactive Bladder Symptom Score) of two or higher and a total Overactive Bladder Symptom Score of three or higher. Multivariate logistic analysis was carried out, with the presence/absence of overactive bladder as the outcome variable, and age, sex, body mass index and diabetes mellitus as covariates.
RESULTS: Of the 72 participants, 17 (24%) were diagnosed with OAB. WMH assessed by the visual rating scale was not associated with OAB. However, participants with OAB showed significantly higher WMH volume than those without OAB. Regionally, participants with OAB showed high WMH volume in the frontal, occipital and parietal lobes. Multiple logistic regression analysis showed that WMH was significantly associated with OAB (OR 1.82, 95% CI 1.11-2.98), after adjustment for clinically important confounders.
CONCLUSIONS: Cerebral WMH volume is associated with OAB, independent of age, sex, body mass index and diabetes mellitus. Geriatr Gerontol Int 2021; 21: 996-1002.
