Seizures in Cerebral Palsy: Types, Impact & Management
Cerebral palsy (CP) results from non-progressive brain injury around birth. 30–50% of individuals with CP develop epilepsy—seizures further complicate neurodevelopment.
Seizure Types in CP
| Type | Features | Typical Onset |
|---|
| Neonatal seizures | Subtle (ocular deviation, cycling); diverse etiologies (HIE, stroke, hemorrhage) | First 28 days |
| Infantile spasms (West syndrome) | Flexor/extensor spasms in clusters; hypsarrhythmia on EEG | 4–8 months |
| Lennox-Gastaut syndrome (LGS) | Multiple types: tonic, atonic, atypical absence; cognitive plateau/regression | 2–6 years |
| Myoclonic seizures | Brief, shock-like jerks | Variable |
| Generalized tonic-clonic | Convulsions, loss of consciousness | Any age |
| Focal seizures | Motor, sensory, autonomic, or awareness impairment | Any age |
Impact on Development
- Cognitive: Frequent seizures disrupt network formation; epileptic encephalopathy risk.
- Motor: Post-ictal weakness worsens baseline CP mobility.
- Safety: Falls, aspiration, injury during seizures.
- Medication burden: AED side effects (sedation, behavioral, bone health).
Management Principles
- Accurate classification: Video-EEG, neuroimaging (MRI), genetic/metabolic workup.
- Targeted AED selection: Broad-spectrum (valproate, levetiracetam, topiramate, lamotrigine, clobazam) for multiple types; avoid carbamazepine/oxcarbazepine in LGS/myoclonic.
- Non-pharmacologic: Ketogenic diet (especially LGS/infantile spasms), VNS, corpus callosotomy, responsive neurostimulation (RNS).
- Comprehensive care: Neurodevelopmental therapy, orthopedics, pulmonology, GI, behavioral health.
- Transition planning: Pediatric → adult neurology continuity.
Early, aggressive seizure control optimizes developmental trajectory in CP.
