For the first time in the world, a device to control epilepsy has been installed in a person's skull

A boy with severe epilepsy has become the first patient in the world to test a new device implanted in his skull to control epileptic seizures.

A neurostimulator that sends electrical signals deep into the brain has reduced Oran Knowlson's daily seizures by 80%.

The patient's mother, Justine, told the BBC that she is happier and that her "quality of life has improved".

The operation was performed in London's "Great Ormond Street" hospital in October. During this period, the patient was 12 years old.

Oran has Lennox-Gastau syndrome, a treatment-resistant form of epilepsy, which he developed when he was three. He had between 20 and 100 attacks every day.

Before the operation, Oran's mother spoke about how epilepsy dominated her son's life: "This disease took away his entire childhood."

He noted that Oran had various forms of seizures, including falling and losing consciousness. Sometimes he stopped breathing and it was necessary to resuscitate him urgently.

In addition to epilepsy, Oran also has autism and ADHD, but Justin says the epilepsy is the biggest obstacle: "I had a healthy three-year-old, and within months of having seizures, he rapidly deteriorated and lost a lot of skills."
