Actress Christina Applegate announces she has multiple sclerosis: "It's been a tough road"

Emmy Award-winning actress Christina Applegate, known for her starring roles in "Married with Children," "Dead to Me," and "Samantha Who?" revealed overnight that she has been diagnosed with multiple sclerosis, a disease in which the body's immune system attacks the central nervous system. 

"A few months ago I was diagnosed with MS," Applegate tweeted. "It's been a strange journey...It's been a tough road. But as we all know, the road keeps going. Unless some a**hole blocks it."  "As one of my friends that MS said 'we wake up and take the indicated action,'" Applegate continued. "And that's what I do. So now I ask for privacy. As I go through this thing."
