The Profile of Epilepsy and its characteristics in Children with Cerebral Palsy.

PURPOSE

To determine the characteristics of epilepsy in children with Cerebral Palsy (CP) visiting the Pediatric Outpatient Department (OPD) of a tertiary care hospital.

METHODS

This cross-sectional study was carried out at a tertiary care pediatric hospital. All children with CP aged between 1 and 12 years seen at this hospital during an 18 months period (January 2018 to July 2019) were included. Children with CP who had seizures were studied in detail. Seizure semiologies were classified according to the International League Against Epilepsy (ILAE) 1981 and 2017 classifications. The severity of seizures was assessed with the Early Childhood Epilepsy Severity Scale (E-Chess). Functional impairment was characterised using the Gross Motor Function Classification System (GMFCS) score.

RESULTS

Of 300 children with CP, 207 (69%) were male and 93 (31%) female. The mean age was 45.17±31.12 months. Seizures were present in 79 (26%) children. 89.9% of children had drug-responsive epilepsy, and 10.1% had refractory epilepsy. Seizures were present in 30.4% of children with a spastic hemiplegia CP subtype, 28.7% with spastic quadriplegia, 26.3% with spastic diplegia, 24% with mixed type CP, and 6.3% with dyskinetic CP. On E-Chess assessment, the median score was 8 (4-14). The majority had poor Gross Motor Function Classification System (GMFCS) scores (>III).

CONCLUSION

The prevalence of epilepsy in the studied population of children with CP was 26%. The highest incidence of seizures was in the spastic hemiplegia subtype (30.4%). The severity of cortical damage is positively correlated with the risk of having epilepsy. The primary determinant of severity of the GMFCS score was the type of CP and not the presence or absence of epilepsy.
