Summary
Seizures are common in childhood stroke, affecting nearly half of young patients. Recurrent seizures are more likely with delayed onset and cortical involvement, highlighting key risk factors for stroke survivors.
Area of Science:
- Pediatric Neurology
- Neuroscience
- Stroke Research
Background:
- Acute hemiplegia in children can be caused by stroke.
- Understanding seizure incidence and recurrence risk after pediatric stroke is crucial.
Purpose of the Study:
- To evaluate the incidence of seizures in children with acute hemiplegia due to stroke.
- To identify risk factors for recurrent seizures following a childhood stroke.
Main Methods:
- Retrospective review of 73 children under 17 with acute hemiplegia from stroke (1978-1992).
- Exclusion of neonatal strokes and those secondary to trauma, malignancy, or infection.
- Analysis of seizure occurrence and recurrence based on stroke type, onset, and cortical involvement.
Main Results:
- 49.3% of children experienced at least one seizure; 28.8% had recurrent seizures.
- Delayed onset of initial seizures was associated with higher recurrence rates (P < .05).
- Cortical involvement significantly increased recurrent seizure risk in both cerebral infarction (51.6% vs 4%, P < .01) and intracranial hemorrhage (33.3% vs 0%).
Conclusions:
- Seizures are a common complication of childhood stroke.
- Risk factors for recurrent seizures include delayed seizure onset and the presence of cortical involvement.
- These findings aid in predicting and managing seizure risk in pediatric stroke patients.
