Multiple sclerosis: Affects more young than most realise

Jack Osbourne, the 26-year-old son of Ozzy and Sharon, has been diagnosed with multiple sclerosis - a condition that is usually associated with older people.

The MS Society says it affects more children and youngsters than most people realise and research has found boys and girls as young as 10 can experience the symptoms.

Michael Absoud, University of Birmingham, says the research raises awareness that this disease does occur in children.

Dominic Hughes met 15-year-old Emily Murdoch, who was diagnosed with childhood MS when she was just 12.
