Abstract. Objective: Daytime urinary incontinence (DUI) is common in childhood. The aim of the study was to neurophysiologically analyse the central emotion processing in children with DUI. Method: In 20 children with DUI (mean age 8.1 years, 55 % male) and 20 controls (mean age 9.1 years, 75 % male) visual event-related potentials (ERPs) were recorded after presenting emotionally valent (80 neutral, 40 positive, and 40 negative) pictures from the International Affective Picture System (IAPS) as an oddball-paradigm. All children received a full organic and psychiatric assessment. Results: Children with DUI did not differ significantly from controls regarding responses to emotional pictures in the frontal, central, and parietal regions and in the time intervals 250–450 ms, 450–650 ms, and 650–850 ms after stimulus onset. The patient group had more psychological symptoms and psychiatric comorbidities than the control group. Conclusions: EEG responses to emotional stimuli are not altered in children with DUI. Central emotion processing does not play a major role in DUI. Further research, including a larger sample size, a more homogeneous patient group (regarding subtype of DUI) or brain imaging techniques, could reveal more about the central processing in DUI.
