Severely epileptic James Walker had spent his whole life unable to talk to his loving family until a high-tech eye tracking machine at his school gave him a voice.
Rhianna fan James has Lennox-Gastaut Syndrome, meaning he used to suffer between 30-50 fits a day before being fitted with an electrical device in his head.
And, although James can see, hear and think just like any other teenager, his severe epileptic attacks meant he never developed properly, so has never learnt to walk or talk.
