Epilepsy surgery in children with accompanying impairments

Area of Science:

• Neurology
• Pediatric Surgery
• Epileptology

Background:

• Epilepsy surgery is a treatment option for drug-resistant epilepsy.
• Children with epilepsy often have co-occurring learning disabilities and neuroimpairments.
• The efficacy of epilepsy surgery in this specific population requires further investigation.

Purpose of the Study:

• To evaluate seizure outcomes two years after epilepsy surgery in pediatric patients.
• To specifically assess the impact of learning disabilities and neuroimpairments on surgical outcomes.
• To determine if these comorbidities are contraindications for epilepsy surgery.

Main Methods:

• A consecutive series of 110 pediatric patients operated on for drug-resistant epilepsy between 1987 and 2006 were assessed.
• Patients' seizure outcomes were evaluated two years post-surgery.
• Data on learning disabilities, motor impairments, neuropsychiatric diagnoses, IQ, and seizure frequency were collected.

Main Results:

• Over half of the children had learning disabilities, 43% had motor impairments, and 30% had neuropsychiatric diagnoses.
• Fifty-six percent of children with an IQ below 70 achieved seizure freedom or a >75% seizure reduction.
• Children with over 100 seizures per month showed a 15 out of 31 seizure-free rate, with seven others experiencing a 50-75% reduction.

Conclusions:

• Learning disability, motor impairment, and psychiatric morbidity are not contraindications for pediatric epilepsy surgery.
• A significant proportion of children with learning disabilities experience worthwhile seizure outcomes, especially after resective surgery.
• Pediatric patients with drug-resistant epilepsy and severe neurological impairments should be referred to tertiary centers for epilepsy surgery evaluation.
