Insights
Severe impairments in children with cerebral palsy (CP) increase epilepsy risk. Epilepsy in CP often presents early with multiple seizure types and high drug resistance, but may resolve in milder cases.
Area of Science:
- Neurology
- Pediatrics
- Clinical Medicine
Background:
- Epilepsy is a common comorbidity in children with cerebral palsy (CP).
- Understanding the factors influencing epilepsy development, resolution, and treatment resistance in CP is crucial for effective management.
- Previous studies have explored associations, but comprehensive clinicoradiological and treatment outcome analyses are needed.
Purpose of the Study:
- To investigate clinicoradiological features associated with epilepsy in children with CP.
- To identify predictors of epilepsy resolution by age 5 years.
- To determine factors associated with drug-resistant epilepsy in this population.
Main Methods:
- Retrospective analysis of the New South Wales/Australian Capital Territory CP Register (n=1916) for children born 2003-2015.
- Comparison of clinical features between children with current epilepsy, resolved epilepsy, and no epilepsy.
- Logistic regression and hierarchical cluster analysis of a subset (n=256) to compare drug-responsive and drug-resistant epilepsy.
Main Results:
- Manual Ability Classification System levels IV-V, intellectual impairment, and vision impairment were associated with epilepsy (p<0.01).
- Moderate-to-severe intellectual impairment predicted epilepsy persistence, while bilateral spastic CP predicted resolution by age 5 (p<0.05).
- Microcephaly and multiple seizure types predicted drug-resistant epilepsy (AUC 0.83).
Conclusions:
- Severe motor and non-motor impairments increase epilepsy risk in children with CP.
- Epilepsy resolution is more likely in milder CP presentations.
- Epilepsy in CP often presents early with high drug resistance, with distinct subgroups identified in genetic causes and surgical candidates.
Aim:
To investigate clinicoradiological features associated with epilepsy, its resolution, and drug resistance in children with cerebral palsy (CP).
Method:
Data were gathered from the New South Wales/Australian Capital Territory CP Register, encompassing children with CP born between 2003 and 2015 (n = 1916). Clinical features and the severity of impairments were compared among three groups: children with current epilepsy (n = 604), those with resolved epilepsy by age 5 years (n = 109), and those without epilepsy (n = 1203). Additionally, a subset of the registry cohort attending Children's Hospital Westmead (n = 256) was analysed to compare epilepsy and treatment characteristics between drug-responsive (n = 83) and drug-resistant groups (n = 147) using logistic regression and hierarchical cluster analysis.
Results:
Manual Ability Classification System levels IV and V, intellectual impairment, and vision impairment were found to be associated with epilepsy in children with CP on multivariable analysis (p < 0.01). Moderate to severe intellectual impairment and bilateral spastic CP were independent positive and negative predictors of epilepsy persistence at the age of 5 years respectively (p < 0.05). Microcephaly and multiple seizure types were predictors of drug-resistant epilepsy (area under the receiver operating characteristic curve of 0.83; 95% confidence interval 0.77-0.9). Children with a known genetic cause (14%) and CP epilepsy surgery group (4.3%) formed specific clinical subgroups in CP epilepsy.
Interpretation:
Our study highlights important clinical associations of epilepsy, its resolution, and treatment response in children with CP, providing valuable knowledge to aid in counselling families and identifying distinct prognostic groups for effective medical surveillance and optimal treatment.
What This Paper Adds:
Severe motor and non-motor impairments in cerebral palsy (CP) increase epilepsy risk. Epilepsy more likely resolves in bilateral spastic and milder CP impairments. Epilepsy in CP often manifests at an early age with multiple seizure types and high drug resistance. Children with a known genetic cause and CP epilepsy surgery group represent distinct clinical subgroups.

Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
