Last October, 12-year-old Trent Brown-Marsh was taken to hospital after suffering a series of unexplained seizures and bad headaches.
Many tests later he was diagnosed with three extremely rare genetic disorders.

He is constantly in and out of hospital, has regular episodes of unbearable pain and has lost almost all sight in one of his eyes.
His long-term prognosis is uncertain.
But through it all Trent has stayed positive and happy.
Trent and his family have been nominated for the Mazda Foundation's Christmas present, so Tristram Clayton went to visit the family with the good news.
