Surgery May Improve Daily Skills In Children With Epilepsy

What was studied

This study looked at everyday functioning in children and teens with drug-resistant epilepsy who had palliative epilepsy surgery. The surgeries were corpus callosotomy or vagus nerve stimulation (VNS). The goal was to evaluate clinical predictors of adaptive functioning over time and the impact of these procedures using adaptive behavior scores.

The researchers reviewed records from 37 pediatric patients treated at one epilepsy surgery program in Brazil between 2007 and 2018. There were 24 children in the callosotomy group and 13 in the VNS group. Adaptive functioning was measured with the Vineland Adaptive Behavior Scales before surgery, about 25 months after surgery, and about 51 months after surgery.

What they found

Before surgery, all patients showed delays in adaptive functioning compared with their age. After surgery, 70.2% had seizure reduction, and most were in Engel class II or III. Antiseizure medicines were reduced in 43.2% of patients.

Adaptive functioning declined at the first follow-up, then improved gradually over longer follow-up. Patients with better seizure control showed greater improvement in adaptive functioning over time. The authors concluded that these palliative surgeries were safe and were associated with seizure reduction, decreased medication burden, and gradual improvement in adaptive functioning.

Limits of the evidence

This was a retrospective observational study, so it cannot establish that surgery caused the changes in adaptive functioning. It included only 37 patients from one center, which limits how widely the results apply. There was no comparison group of similar children who did not have surgery.

The abstract does not give detailed results for callosotomy versus VNS separately, so it is unclear whether one procedure had better adaptive outcomes than the other. It also does not describe all possible factors that could affect development over time.

For families and caregivers

For families, this study suggests that palliative surgery for severe epilepsy may be associated with benefits beyond seizure counts alone. Some children had fewer seizures and needed fewer medicines, and over the longer term there were improvements in daily-life skills, especially when seizure control was better.

It is also important to know that adaptive skills did not improve right away in this study and declined at the first follow-up before improving later. This means families may need to think about progress over years, not just months.

What to watch next

Larger studies that follow children prospectively and compare outcomes by surgery type and seizure control would help clarify these findings.

vagus nerve stimulation (VNS)

A treatment that uses a small implanted device to send electrical signals through the vagus nerve to help reduce seizures.

adaptive functioning

Everyday skills used for communication, social life, and practical tasks like self-care.

Vineland Adaptive Behavior Scales

A standard test used to measure everyday functioning and developmental skills.

Engel scale

A system doctors use to describe seizure outcomes after epilepsy treatment.
