COLLECT - Jamie Drysdale dressed in bowling kit at home 21st May 2014. The family of a teenager who tragically died after suffering a seizure have spoken out for the first time about their tragic loss. See CENTRE PRESS story CPSLEEP. Jamie Drysdale, 18, is believed to have suffered from a rare condition known as Sudden Death in Epilepsy (SUDEP) in February. His mum, Kathryn, 50, went to wake Jamie and asked whether he could take the dog out, before he stirred and muttered "okay, mum". But when she returned ten minutes later to give him a nudge, Kathryn found her eldest boy lying unconscious on the floor. Frantic attempts were made to revive Jamie, but by the time paramedics arrived at the house in Kirkliston, West Lothian, he died.
