A boy with severe epilepsy has become the first patient in the world to trial a new device fitted in their skull to control seizures.

The neurostimulator, which sends electrical signals deep into his brain, has reduced Oran Knowlson’s daytime seizures by 80%.

The surgery was carried out in October as part of a trial at Great Ormond Street Hospital in London when Oran - who is now 13 - was 12.
Epilepsy seizures are triggered by abnormal bursts of electrical activity in the brain.

The device, which emits a constant pulse of current, aims to block or disrupt the abnormal signals.
