Insights
Spastic tetraplegic cerebral palsy presents with more severe motor impairments and higher rates of epilepsy and intellectual disability compared to spastic diplegic cerebral palsy. These findings highlight key differences in clinical presentation and neurological involvement.
Area of Science:
- Neurology
- Pediatrics
- Developmental Pediatrics
Background:
- Cerebral palsy (CP) is a group of movement disorders due to early brain damage.
- Spastic diplegia and spastic tetraplegia are common subtypes of CP with distinct clinical characteristics.
Purpose of the Study:
- To compare spastic diplegic cerebral palsy (SDCP) and spastic tetraplegic cerebral palsy (STCP).
- To analyze risk factors, seizure prevalence, CP severity, EEG, and MRI findings in both CP subtypes.
Main Methods:
- Retrospective analysis of 38 children with SDCP and 48 with STCP.
- Evaluation of gestational history, birth weight, Apgar scores, Gross Motor Function Classification System (GMFCS) levels, and neurological assessments.
- Analysis of electroencephalogram (EEG) and magnetic resonance imaging (MRI) findings.
Main Results:
- STCP patients had lower Apgar scores, higher GMFCS levels (IV-V), and more frequent mental retardation.
- Periventricular leukomalacia was more common in SDCP, while cerebral atrophy was more frequent in STCP.
- Epilepsy and intractable epilepsy occurred significantly more often in children with STCP.
Conclusions:
- Spastic tetraplegia is associated with poorer neurological outcomes, including more severe motor deficits, intellectual disability, and a higher burden of epilepsy.
- Differences in MRI findings like cerebral atrophy suggest distinct pathophysiological mechanisms between SDCP and STCP.
Abstract:
The aim of this study was to compare spastic diplegic and tetraplegic cerebral palsy. Thirty-eight children had spastic diplegic cerebral palsy and 48 spastic tetraplegic cerebral palsy. Risk factors of cerebral palsy, seizures, severity of cerebral palsy, electroencephalogram, and magnetic resonance imaging findings were analyzed. Gestational history, low birth weight, and perinatal pathologies were present in similar percentages in both groups. Lower values of the Apgar score were recorded more often in the tetraplegic cerebral palsy group than the diplegic group. The children with spastic diplegia were classified more frequently into levels I and II of the Gross Motor Function Classification System, but patients with spastic tetraplegia were classified more frequently into levels IV and V. Similarly, mental retardation was observed more frequently in the patients with spastic tetraplegia. In magnetic resonance imaging, periventricular leukomalacia was detected in a higher proportion of children with spastic diplegia than in patients with tetraplegia. Cerebral atrophy occurred more frequently in the tetraplegic group compared with diplegic patients. Twenty-four (50.0%) children with spastic tetraplegia had epilepsy compared with six children with spastic diplegia. The incidence of intractable epilepsy was higher in the tetraplegic patients than in the children with spastic diplegia.
