Insights
Children with faecal incontinence (FI) show heightened emotional processing responses, suggesting a neurobiological vulnerability linked to the enteric (ENS) and central nervous systems (CNS). This differs from children with Attention-deficit hyperactivity disorder (ADHD).
Area of Science:
- Neuroscience
- Pediatrics
- Gastroenterology
Background:
- Faecal incontinence (FI) is a common condition affecting both the enteric (ENS) and central nervous systems (CNS).
- Understanding the neurophysiological basis of emotional processing in children with FI is crucial for effective treatment.
- Attention-deficit hyperactivity disorder (ADHD) shares some neurodevelopmental pathways, making it a relevant comparison group.
Purpose of the Study:
- To neurophysiologically analyze the central processing of emotions in children with FI.
- To compare emotional processing in children with FI, healthy controls, and children with ADHD.
- To investigate potential neurobiological links between ENS and CNS in FI.
Main Methods:
- Included 14 children with FI and constipation, 9 with non-retentive FI, 15 controls, and 13 with ADHD.
- Utilized physical exams, sonography, Child Behavior Checklist, psychiatric interviews, and intelligence tests.
- Recorded acoustic evoked potentials and event-related potentials using standardized methods with emotional and stool-related picture stimuli.
Main Results:
- Children with FI exhibited significantly stronger responses to most stimuli across frontal, central, and parietal regions compared to controls.
- Children with constipation showed even stronger responses.
- No significant differences in emotional processing or acoustic evoked potentials were observed between children with ADHD and controls.
Conclusions:
- Children with FI demonstrate heightened emotional processing, indicating a potential neurobiological vulnerability.
- This vulnerability may stem from the intricate association between the enteric (ENS) and central nervous systems (CNS).
- Findings differentiate FI's emotional processing from that seen in ADHD.
Aim:
Faecal incontinence (FI) is a common disorder involving both the enteric (ENS) and central nervous systems (CNS). The aim of the study is to analyze neurophysiologically the central processing of emotions in children with FI, healthy controls and children with Attention-deficit hyperactivity disorder (ADHD).
Methods:
Fourteen children with FI and constipation, nine with non-retentive FI, 15 controls and 13 children with ADHD were examined. The methods included a physical exam, sonography, Child Behavior Checklist, a psychiatric interview and intelligence test. Acoustic evoked potentials were recorded according to standardized methodology. For the event-related potentials, 80 neutral, 40 positive and 40 negative pictures from the International Affective Picture System (IAPS), and 40 pictures depicting faeces were presented.
Results:
Children with FI had significantly more intense responses for most stimuli over the frontal, central and parietal regions compared to controls. Stool pictures did not evoke stronger responses than other stimuli. Children with constipation elicited stronger responses. Children with ADHD did not differ from controls. Acoustic evoked potentials were comparable in all groups.
Conclusions:
Children with FI have increased responses in the processing of emotions. These can be interpreted as a neurobiological vulnerability, possibly due to the association of the ENS and CNS.
