Background/Purpose: Children with attention deficit hyperactivity disorder (ADHD) tend to be more vulnerable to various forms of voiding dysfunction and nocturnal enuresis (NE). We attempt to compare the clinical manifestations and attentional performance between ADHD children with NE and those without NE. Methods: We consecutively enrolled children diagnosed with ADHD in child and adolescent psychiatric clinics. The questionnaires for evaluation of ADHD symptoms and voiding dysfunction symptoms were administered to all study participants. All participants also received the Test Battery for Attention Performance (TAP) for assessment of attentional function. Results: A total of 53 children were enrolled in this study, comprising 47 boys and six girls. The prevalence rate of NE was 28.3%. Children in the NE group had statistically significant higher dysfunctional voiding symptom score (5.40 +/- 3.66 vs. 3.16 +/- 2.74; p = 0.018) and two subscales of When I wet myself, my underwear is soaked (p < 0.001) and I miss having a bowel movement every day (p = 0.047). There were no significant differences with regard to all psychiatric evaluations between the NE and non-NE groups. In the TAP test, the NE group showed a significantly shorter reaction time in the domain of inhibitory control, working memory, and auditory sustained attention than the non-NE group. Conclusion: Children with ADHD have a high prevalence of NE. ADHD children with NE had a significantly higher dysfunctional voiding symptom score and shorter reaction time in most domains of the TAP test. Further study is needed to discern the impact of NE on the neuropsychological function of ADHD children. Copyright (C) 2012, Elsevier Taiwan LLC & Formosan Medical Association. All rights reserved.
