Comorbidity of ADHD and incontinence in children

ADHD and incontinence are common childhood disorders which co-occur at much higher rates than expected by chance. The aim of this review was to provide an overview both of the comorbidity of nocturnal enuresis (NE), daytime urinary incontinence (DUI) and faecal incontinence (FI) in children with ADHD; and, vice versa, of the co-occurrence of ADHD in children with NE, DUI and FI. Most clinical studies have focussed on the association of ADHD and NE. Population-based studies have shown that children with DUI have an even greater risk for ADHD than those with NE. While children with FI have the highest overall comorbidity rates of psychological disorders, these are heterogeneous with a wide range of internalising and externalising disorders—not necessarily of ADHD. Genetic studies indicate that ADHD and NE, DUI and FI do not share the same genetic basis. The comorbidity is conferred by non-genetic factors. Possible aetiological and pathogenetic links between ADHD and incontinence are provided by neurophysiological, imaging and pharmacological studies. The co-occurrence has clinical implications: children with ADHD and NE, DUI and FI are more difficult to treat, show lower compliance and have less favourable treatment outcomes for incontinence. Therefore, both groups of disorders have to be assessed and treated specifically.

Eating problems in young children -- a population-based study.

To analyse the prevalence of atypical eating problems and their associations with anxious or oppositional behaviours in young children.

Specific behavioral comorbidity in a large sample of children with functional incontinence: Report of 1,001 cases.

Psychological comorbidity among children with functional incontinence is high: 20–30% of children with nocturnal enuresis (NE), 20–40% of those with daytime urinary incontinence (DUI) and 30–50% of those with fecal incontinence (FI) have clinically relevant comorbid disorders. The aim of this study was to analyze specific comorbid behavioral symptoms for different subtypes of incontinence in a large group of children.

Incontinence in children with autism spectrum disorder

INTRODUCTION Autism spectrum disorder (ASD) and incontinence (nocturnal enuresis (NE), daytime urinary incontinence (DUI), fecal incontinence (FI)) are relevant disorders in childhood. In general, children with special needs such as intellectual disability (ID) or ASD are more often affected by incontinence than typically developing children. OBJECTIVE In the few studies conducted on children with ASD, gastrointestinal (GI) symptoms have received more attention than NE, DUI and lower urinary tract symptoms (LUTS). The aim of the present study was to assess the prevalence of incontinence, LUTS and psychological symptoms/disorders in children with ASD compared to controls. STUDY DESIGN Forty children with ASD (12 children with infantile or childhood autism, 15 with atypical autism and 13 with Aspergers syndrome) (mean age 11.3 years) and 43 age-matched control children (mean age 10.7 years) were assessed. A questionnaire referring to incontinence and the International Consultation on Incontinence Questionnaire-Pediatric LUTS (ICIQ-CLUTS) were administered. Child psychopathology was assessed with the Child Behavior Checklist (CBCL/4-18). Child psychiatric ICD-10 diagnoses were based on a structured psychiatric interview (Kinder-DIPS). RESULTS Children with ASD showed increased rates of NE (30.0% vs 0%) and DUI (25.0% vs 4.7%) compared to controls. Among children with ASD, daytime bladder control (≥5 years of age: 20.5% vs 0%) and bowel control (≥4 years of age: 42.5% vs 7.5%) were delayed compared to controls. Children with ASD had a higher LUTS score. Additionally, children with ASD were more often affected by psychological symptoms and disorders. Rates of clinically relevant externalizing symptoms (32.5% vs 0%), internalizing symptoms (67.5% vs 9.3%) and total problem score (70.0% vs 2.1%) were higher in children with ASD than the controls (see table). Children with ASD had more ICD-10 diagnoses than the controls (47.5% vs 4.7%). DISCUSSION The present study showed that children with ASD are more at risk of DUI and NE than healthy controls. In addition, children with ASD had more LUTS, especially urgency and postponement, and they needed a longer time to become dry and continent. Additionally, according to the parental CBCL questionnaire, children with ASD showed higher rates of clinically relevant psychological symptoms (externalizing and internalizing symptoms), and according to the psychiatric interview, they had higher rates of comorbid psychological disorders. CONCLUSION Autism spectrum disorder is an incapacitating disorder with significant impairment in social functioning. In most cases, psychological symptoms and disorders co-occur. Additionally, children with ASD are at a greater risk of being affected by different forms of incontinence and LUTS. Therefore, screening for incontinence and, if indicated, treatment of these disorders is recommended.

Elimination disorders in persons with Prader-Willi and Fragile-X syndromes.

Elimination disorders are common in typically developing children. Only few studies have addressed elimination disorders in persons with intellectual disability (ID)—and even fewer studies in those with specific syndromes. The aim of the study was to investigate the rates of elimination disorders and behavioral symptoms in persons with Prader–Willi (PWS) and Fragile‐X syndromes (FXS) in a large sample.

Incontinence in children with treated attention-deficit/hyperactivity disorder.

INTRODUCTION Attention-deficit/hyperactivity disorder (ADHD) and incontinence (nocturnal enuresis, daytime urinary incontinence and fecal incontinence) are common disorders in childhood. Both disorders are strongly associated with each other. OBJECTIVE ADHD can affect compliance to incontinence therapy in a negative way; it can also affect outcome. The aim of the present study was to assess the prevalence of incontinence, age of bladder and bowel control, and psychological symptoms in children having treatment for ADHD compared to a control group. STUDY DESIGN Forty children having treatment for ADHD (75% boys, mean age 11.4 years) and 43 matched controls (60.5% boys, mean age 10.7 years) were assessed. Their parents filled out questionnaires to assess: child psychopathology (Child Behavior Checklist), incontinence (Parental Questionnaire: Enuresis/Urinary Incontinence; Encopresis Questionnaire - Screening Version) and symptoms of the lower urinary tract (International-Consultation-on-Incontinence-Questionnaire - Pediatric Lower Urinary Tract Symptoms). The ICD-10 diagnoses and childrens IQ were measured by standardized instruments (Kinder-DIPS, Coloured Progressive Matrices/Standard Progressive Matrices). RESULTS Rates of incontinence in the ADHD group (5% nocturnal enuresis, 5% daytime urinary incontinence, 2.5% fecal incontinence) did not differ significantly from incontinence rates in the control group (4.7% daytime urinary incontinence). More children in the ADHD group had Child Behavior Checklist scores in the clinical range. Further ICD-10 disorders were present in eight children with ADHD and in one control child. More children with ADHD had delayed daytime and nighttime bladder control, as well as delayed bowel control, than the controls. DISCUSSION The present study showed that if children are treated for their ADHD, according to standard practice guidelines, incontinence rates are similar to those without ADHD. More children with ADHD reached continence at a later age than the controls, which could be an indicator of maturational deficits in the central nervous system. Additionally, children with ADHD showed higher rates of clinically relevant psychological symptoms. CONCLUSION This study provides further information of the association between ADHD and incontinence. Treatment of ADHD may be associated with positive effects on incontinence outcomes. Therefore, children with ADHD should always be screened for incontinence problems and children with incontinence problems should also be screened for ADHD if symptoms of hyperactivity, inattention and/or impulsivity are also present.

Central nervous system processing of emotions in children with nocturnal enuresis and attention-deficit/hyperactivity disorder.

Nocturnal enuresis (NE) and attention‐deficit/hyperactivity disorder (ADHD) are common in childhood. We analysed the central processing of emotions in children with NE, ADHD, NE + ADHD and controls.

Voiding postponement in children—a systematic review

Voiding postponement (VP) has been defined as a habitual postponement of micturition using holding maneuvers. VP can represent both a symptom, as well as a condition. As divergent definitions are used internationally, the aim was to review the current state of knowledge on VP and provide recommendations for assessment, diagnosis and treatment. A Scopus and a Pubmed search was conducted, entering the terms ‘voiding postponement’ without any restrictions or specifications. Other publications relevant to the topic were added. VP can represent a symptom in healthy children. As a condition, VP in combination with nocturnal enuresis (NE) is a subtype of non-monosymptomatic NE. Most studies have focused on daytime urinary incontinence (DUI) with VP, or more aptly termed voiding postponement incontinence (VPI). It is a behaviorally defined syndrome, i.e., by the habitual deferral of micturition and DUI. VPI is associated with a low micturition frequency, urgency and behavioral problems. The most common comorbid disorder is oppositional defiant disorder (ODD). VP as a symptom and VPI as a condition should be differentiated. VPI is a common disorder with many associated problems and disorders. Urotherapy and timed voiding are the main treatment approaches. Due to the high rate of comorbid ODD, other forms of treatment, especially cognitive behavioral therapy, are often needed.

Incontinence in children, adolescents and adults with Williams syndrome.

Williams Syndrome (WS) is a microdeletion syndrome (chromosome 7q11.23) characterized by typical facial features, cardiovascular disease, behavioural symptoms, and mild intellectual disability (ID). The aim of this study was to assess the rates of incontinence and psychological problems in persons with WS.
