Behaviour in mucopolysaccharide disorders
1Academic Department of Child Health, Chelsea and Westminster Hospital, London.
Insights
Behavioral issues are common in children with mucopolysaccharide disorders, especially Sanfilippo and Hunter diseases. Parents need more support managing these challenges, which significantly impact families.
Area of Science:
- Pediatric Psychology
- Rare Genetic Disorders
- Behavioral Science
Background:
- Mucopolysaccharide disorders (MPS) are a group of rare genetic conditions.
- Behavioral problems are frequently observed in children with MPS, but their nature and prevalence require further investigation.
- Understanding these behavioral challenges is crucial for providing adequate support to affected children and their families.
Purpose of the Study:
- To investigate the nature and prevalence of behavioral problems in children with mucopolysaccharide disorders.
- To identify specific behavioral issues and affected subtypes and age groups.
- To assess the level of support received by parents for managing these behaviors.
Main Methods:
- A study involving 258 children diagnosed with mucopolysaccharide disorders.
- Data collection through postal questionnaires, supplemented by home visits to 42 families.
- Discussions with families at Society for Mucopolysaccharide Diseases meetings.
Main Results:
- High rates of behavioral problems were identified, particularly in children aged 5–9 years with Sanfilippo's and Hunter's disease.
- Common issues included destructiveness, restlessness, and aggressiveness.
- Sleep problems affected 66% of children across all subtypes.
Conclusions:
- Behavioral problems are a primary characteristic of mucopolysaccharide disorders.
- These challenges impose a significant strain on families.
- There is an urgent need for improved services and support systems for families managing these behaviors.
Abstract:
This paper reports a study of the nature and prevalence of behaviour problems in 258 children with mucopolysaccharide disorders. Questionnaire data obtained through the post was supplemented by home visits to 42 families in the sample and by regular discussions with families at meetings of the Society for Mucopolysaccharide Diseases. High rates of behaviour problems were found, particularly in children with Sanfilippo's and Hunter's disease aged 5 to 9 years. These included destructiveness, restlessness, and aggressiveness. Sleep problems were common across subtypes with an overall prevalence of 66%. Parents reported that they received little or no support in the management of these difficult behaviours. It is concluded that behaviour problems are a primary feature of the mucopolysaccharide disorders and place a major strain on families. Services to help families cope with these problems are urgently needed.
