A mum is determined to keep fighting to find a cure after her son was diagnosed with a rare and fatal muscle wasting condition.

Nine-year-old Dexter Dickson, of Dundee, has Duchenne Muscular Dystrophy, one of the most severe forms of muscular dystrophy.

Dexter's mum and full-time carer, Rachel Williamson, first noticed something was not quite right when her son was three.
