Insights
Early diagnosis of cerebral palsy (CP) is crucial. This study highlights white matter injury as the main cause and intellectual disability as a frequent comorbidity in CP cases.
Area of Science:
- Neurology
- Pediatrics
- Developmental Pediatrics
Background:
- Cerebral palsy (CP) is a nonprogressive movement disorder caused by prenatal or perinatal brain injury.
- Early diagnosis and intervention are vital for managing CP, but optimal timing remains debated.
Purpose of the Study:
- To analyze clinical features in a large cohort of children with cerebral palsy.
- To inform early detection and intervention strategies for CP.
Main Methods:
- Retrospective review of medical records from a university hospital.
- Inclusion criteria: children aged ≥24 months or followed up for ≥24 months.
- Diagnosis and subtyping based on International Classification of Diseases-10.
Main Results:
- 2012 CP cases analyzed; 68.84% male, 51.44% spastic diplegia.
- White matter injuries (46.58%) were the predominant MRI finding; maldevelopment was rare (7.05%).
- Intellectual disability co-occurred in 43.44% of cases, highest in mixed types (73.85%).
Conclusions:
- White matter injury is the primary pathology in CP.
- Intellectual disability is a common comorbidity, varying by CP subtype.
- Diagnostic precision improves with age, supporting early detection and tailored interventions.
Introduction:
Cerebral palsy (CP) is a nonprogressive movement disorder resulting from a prenatal or perinatal brain injury that benefits from early diagnosis and intervention. The timing of early CP diagnosis remains controversial, necessitating analysis of clinical features in a substantial cohort.
Methods:
We retrospectively reviewed medical records from a university hospital, focusing on children aged ≥24 months or followed up for ≥24 months and adhering to the International Classification of Diseases-10 for diagnosis and subtyping.
Results:
Among the 2012 confirmed CP cases, 68.84% were male and 51.44% had spastic diplegia. Based on the Gross Motor Function Classification System (GMFCS), 62.38% were in levels I and II and 19.88% were in levels IV and V. Hemiplegic and diplegic subtypes predominantly fell into levels I and II, while quadriplegic and mixed types were mainly levels IV and V. White matter injuries appeared in 46.58% of cranial MRI findings, while maldevelopment was rare (7.05%). Intellectual disability co-occurred in 43.44% of the CP cases, with hemiplegia having the lowest co-occurrence (20.28%, 58/286) and mixed types having the highest co-occurrence (73.85%, 48/65). Additionally, 51.67% (697/1,349) of the children with CP aged ≥48 months had comorbidities.
Conclusions:
This study underscores white matter injury as the primary CP pathology and identifies intellectual disability as a common comorbidity. Although CP can be identified in infants under 1 year old, precision in diagnosis improves with development. These insights inform early detection and tailored interventions, emphasizing their crucial role in CP management.
