Epilepsy: a new way to treat children with uncontrolled seizures

Published on


Over 60,000 children and teenagers aged 18 and under have epilepsy in the UK.1 Sadly, medication doesn’t work for up to one third of these young people.2-3 There are other ways to treat epilepsy, but some children carry on having seizures, which can be unpleasant and unpredictable. Dr Antonio Valentin, of King’s College London, is investigating the potential of a possible new treatment for children with uncontrolled seizures, which involves electrical stimulation of the brain. He hopes this will greatly improve the quality of life of children with severe epilepsy who’ve found that existing treatments don’t work for them.

Action Medical Research and Great Ormond Street Hospital Children's Charity are jointly funding this research.​

How are children’s lives affected now?

“If a child’s epilepsy cannot be controlled, it can seriously disrupt their life both at home and at school,” says Dr Valentin. “The most severely affected children can have hundreds of seizures every day.”

Seizures can be frightening and disruptive, for children and their families. The exact nature of children’s seizures varies. Some children, for example, lose consciousness and have convulsions, meaning their body shakes uncontrollably. Other children may enter a trance-like state, or experience unusual sensations such as a strange taste in their mouth.

“If treatment doesn’t work, children with epilepsy can’t be sure when they’ll have their next seizure, which can impact greatly on activities such as schooling, hobbies or just being out and about,” says Dr Valentin. “Children may feel different from their peers, and their seizures can put them at risk of injury. Sadly, on rare occasions, epilepsy sometimes even causes death.”

How could this research help?

“We’re developing a new way to treat children with severe epilepsy whose seizures can’t be controlled by existing treatments,” says Dr Valentin.

Treatment involves stimulating very specific parts of the brain using electrodes placed under the skull. Two techniques are being used, called cortical stimulation and deep brain stimulation.

“We’ve already treated two young adults with cortical stimulation and one child with deep brain stimulation, with promising results. In addition a short period of cortical stimulation was very useful for a six-year old boy who had more than 30 seizures a day. He has been seizure free for 20 months

“In this project, we hope to identify the best way to administer the new treatment and find out more about how it works, so that a much larger clinical trial can follow,” adds Dr Valentin. “Given the effects of uncontrolled epilepsy on children’s attainment at school, psychological wellbeing and future employment prospects, a treatment that stops some, or all, of their seizures could improve their quality of life significantly – throughout childhood and beyond.”
