Epilepsy in hydrocephalic children.

Area of Science:

• Pediatric Neurology
• Neurosurgery
• Epileptology

Background:

• Hydrocephalus (HC) is a common condition in children, often requiring shunt treatment.
• Epilepsy is a frequent comorbidity in children with hydrocephalus.
• The relationship between shunt treatment, hydrocephalus, and epilepsy requires further investigation.

Purpose of the Study:

• To investigate the incidence and characteristics of epilepsy in children with hydrocephalus undergoing shunt treatment.
• To identify risk factors and predictive markers for epilepsy in this cohort.
• To evaluate the efficacy of prophylactic anticonvulsant medication.

Main Methods:

• Retrospective study of 168 children with hydrocephalus treated with shunts.
• Analysis of seizure occurrence, electroencephalogram (EEG) findings, and shunt-related complications.
• Correlation of epilepsy with etiological factors, shunt revisions, infections, and slit ventricles (SLV).

Main Results:

• 47.6% of patients experienced epileptic seizures during a mean follow-up of 8.9 years.
• Epilepsy onset occurred both before and after initial shunting.
• Generalized spike and wave activity (SWA) on EEG, particularly in neonates, was associated with persistent seizures.
• Prophylactic anticonvulsant medication reduced seizure incidence (68.1% seizure-free) compared to no medication.
• Slit ventricles (SLV) were more frequently associated with epilepsy after the first postoperative year.

Conclusions:

• Epilepsy is a significant concern in shunt-treated hydrocephalic children.
• Neonatal EEG findings, specifically generalized SWA, may predict persistent epilepsy.
• Prophylactic anticonvulsant therapy appears effective in preventing seizures.
• The development of slit ventricles may be a risk factor for late-onset epilepsy.
