Enuresis and hyperventilation response in the EEG
Insights
Children with primary enuresis (bed-wetting from birth) show increased hyperventilation responses, suggesting brain dysfunction. Secondary enuresis (later onset) appears linked to psychological factors, not brain instability.
Area of Science:
- Neuroscience
- Pediatrics
- Child Psychology
Background:
- Enuresis, or involuntary urination, is common in children.
- Hyperventilation response on electroencephalogram (EEG) can indicate brain dysfunction or delayed maturation.
- Understanding the underlying causes of primary and secondary enuresis is crucial for effective management.
Purpose of the Study:
- To investigate the relationship between hyperventilation response on EEG and enuresis in children.
- To differentiate potential causes of primary versus secondary enuresis.
- To explore the role of cerebral control and maturation in childhood enuresis.
Main Methods:
- Electroencephalogram (EEG) examinations were performed on 420 enuretic children (ages 4-15) and 100 controls.
- Hyperventilation response was assessed as a measure of cortical instability.
- Children were categorized into primary (from birth) and secondary (later onset) enuresis groups.
Main Results:
- An increased hyperventilation response was significantly more common in children with primary enuresis, irrespective of uropathy.
- Children with primary enuresis also showed a higher prevalence of pathological resting EEGs.
- Children with secondary enuresis exhibited hyperventilation responses similar to control groups.
Conclusions:
- Disturbed cerebral control, indicated by hyperventilation response, is a significant factor in primary enuresis.
- Delayed maturation or cortical instability may underlie primary enuresis.
- Psychological factors are likely more influential in the development of secondary enuresis.
Abstract:
A total of 420 enuretic children aged between four and 15 years and 100 controls were examined by EEG in order to determine their hyperventilation response, which is considered to be a non-specific sign of brain dysfunction or of cortical instability as a result of delayed maturation. It was found that an increased hyperventilation response occurred mainly among children with primary enuresis (bed-wetters from birth). This was true even if the children had a 'uropathy'. It was also commoner among the children with pathological EEGs at rest. The results for those with secondary enuresis (later onset) were similar to the controls. These findings indicate that disturbed cerebral control of the bladder is an important factor in primary enuresis. Psychological factors are thought to account for the occurrence of secondary enuresis.
