Sharon Osbourne on Jack's MS Diagnosis: 'Osbournes Survive Everything'

When his sight began to fail him last month, reality TV star Jack Osbourne realized he needed to seek medical help. He received the news he has multiple sclerosis.

The Osbourne family has banded together and is remaining positive about Jack's prognosis. Matriarch Sharon told People, “Osbournes survive everything. We really do."

"I couldn't see anything in front of me," Jack, 26 told People.com, having lost 80 percent of sight in his right eye. MS is an autoimmune disease that attacks the central nervous system, including the brain and spinal cord, and can impact muscle control.

UCLA neurologist Dr. Barbara Giesser told “Extra,” “MS is not a fatal disease. Patients will have the onset of a varied number of symptoms, like an attack of vision problems or numbness. This almost always gets better.”

Jack is now beginning medication and adopting a healthier diet regimen, and his vision has indeed improved. "It's just one of those things you take as it comes," he said. "It's all about your outlook."

Jack, who became a father in April with the arrival of daughter Pearl Clementine, added, "My life is far from over.”
