London, June 18 (ANI): The Osbourne family have revealed that son Jack has multiple sclerosis (MS), after he was diagnosed from tests taken when he lost 60 percent vision in his right eye earlier this year.

The rocker's son told Hello! Magazine that after first feeling angry and upset he has now taken an attitude of adapt and overcome.

MS is an incurable neurological condition that damages the nerves and affects the transfer of messages around the body.

Jack, 26, said that he had chosen to speak out in order to raise awareness of the condition.

He added that the support of his fiance Lisa Stelly was helping him to stay positive.

MS can have a wide range of symptoms, including tiredness, temporary blindness, loss of co-ordination and speech difficulties.

It is unpredictable and affects everyone differently. One in five sufferers has a benign form with mild attacks and no permanent disability, while another 15 percent have a progressive disease that steadily worsens.

Jack Osbourne was diagnosed with the condition three weeks after the birth of daughter Pearl, now two months old.

The timing was so bad. I'd just had a baby, work was going great - I kept thinking: 'Why now?' the BBC quoted him as saying.

Parents Ozzy and Sharon said they were still trying to come to terms with their son's condition.

Former 'X Factor' judge Sharon said she had been asking herself if she was to blame.

I kept thinking: 'What did I do wrong, what did I eat or drink when I was pregnant?' I feel like it's somehow my fault, she said.

The legendary rocker also expressed concern over his child's condition.

If it was me, you'd think: 'Ozzy had a reputation and it caught up with him,' but Jack is such a good guy, he said.

Jack, known as an extreme sports enthusiast, will use a combination of daily drug treatments, holistic therapies and lifestyle changes. (ANI)
