Impaired selective attention in patients with severe primary monosymptomatic nocturnal enuresis: An event-related potential study

Highlights • We found impaired selective attention in patients with PMNE. • The impaired selective attention was more evidence in patients with severe PMNE. • Measures to improve selective attention might help in treatment of severe PMNE.
Objectives Primary monosymptomatic nocturnal enuresis (PMNE) is a very common problem in school age children. It is thought that PMNE represents a maturational lag in the central nervous system of those children. We did this case control study to assess the selective attention and resource allocation in those children using the P300 wave of the Event-Related Potentials (ERPs) and its relation to disease severity. Methods Forty four patients with PMNE and twenty three healthy controls were included in this study. Patients were diagnosed according to the criteria of international children’s continence society and were classified into two groups; patients with frequent wetting (≥4 episodes/week), and patients with infrequent wetting (
