Insights
Pediatric muscular dystrophies (MDs) impair social cognition, affecting emotion recognition and theory of mind (ToM). Early screening is vital for improving quality of life in children with MDs.
Area of Science:
- Neurology
- Psychology
- Pediatrics
Background:
- Pediatric muscular dystrophies (MDs) are rare neuromuscular diseases causing progressive muscle degeneration.
- A neuropsychosocial approach is essential for managing MDs due to associated comorbidities.
- The social cognitive domain in pediatric MDs remains under-addressed.
Purpose of the Study:
- To analyze social cognition performance in pediatric patients with MD.
- To compare social cognition in children with MDs versus healthy controls.
- To investigate the impact of general intelligence and behavioral symptoms on social cognition in MDs.
Main Methods:
- Cross-sectional study with 32 pediatric MD patients and 32 matched healthy controls.
- Utilized NEPSY-II Social Perception Domain, Reading the Mind in the Eyes Test-Child, and Happé's Strange Stories Test.
- Controlled for general intelligence and behavioral/emotional symptoms; assessments were remote.
Main Results:
- Children with MDs showed significantly poorer performance on most social cognition tasks.
- Impairments in theory of mind (ToM) were partially explained by general intelligence levels.
- Emotion recognition deficits were independent of general intelligence and behavioral/emotional symptoms.
Conclusions:
- Social cognition, including emotion recognition and ToM, is impaired in pediatric MD patients.
- Screening for social cognition deficits is recommended for early intervention.
- Improving social cognition can enhance the quality of life for children with MDs.
Introduction:
Pediatric muscular dystrophies (MDs) are a heterogeneous group of rare neuromuscular diseases characterized by progressive muscle degeneration. A neuropsychosocial approach is crucial for these patients due to associated cognitive, behavioral, and psychiatric comorbidities; however, the social cognitive domain has not been adequately addressed.
Methods:
This study aimed to analyze on social cognition performance in a pediatric MD patient cohort. This cross-sectional study included 32 pediatric patients with MD and 32 matched-healthy controls. The Social Perception Domain of the NEPSY-II, the Reading the Mind in the Eyes Test-Child and Happé's Strange Stories Test were administered. General intelligence and behavioral and emotional symptoms were controlled for to eliminate covariables' possible influence. The assessments were performed remotely.
Results:
Children with MDs performed significantly worse on most of the social cognition tasks. The differences found between the groups could be explained by the level of general intelligence for some aspects more related to theory of mind (ToM) (TM NEPSY-II: F = 1.703, p = .197; Verbal task: F = 2.411, p = .125; RMET-C: F = 2.899, p = .094), but not for emotion recognition. Furthermore, these differences were also independent of behavioral and emotional symptoms.
Discussion:
In conclusion, social cognition is apparently impaired in pediatric patients with MD, both for emotion recognition and ToM. Screening assessment in social cognition should be considered to promote early interventions aimed at improving these patient's quality of life.
