NASCAR driver Trevor Bayne has been diagnosed with multiple sclerosis, according to his racing team.
Multiple sclerosis is a chronic disease that affects the central nervous system, often causing pain, numbness in the limbs and a loss of vision. Symptoms vary by patient and can disappear for months at a time, making it difficult to diagnose early on.
Doctors have cleared Bayne, 22, to compete, said a statement by Roush Fenway Racing.
“I am in the best shape I’ve ever been in, and I feel good,” Bayne said. “There are currently no symptoms and I’m committed to continuing to take the best care of my body as possible.”
Bayne was the youngest driver in NASCAR history to win the Daytona 500 in 2011. He said he plans to race in the NASCAR Nationwide Series Championship in 2014.
Scientists do not know what causes multiple sclerosis, according to the Mayo Clinic, although a person’s risk increases if a family member has the disease.
