Married… with Children and Dead to Me star Christina Applegate revealed via Twitter this morning that she was diagnosed with multiple sclerosis. The actress revealed that she was diagnosed a few months ago, and it has been a “strange journey.”

Hi friends. A few months ago I was diagnosed with MS. It’s been a strange journey. But I have been so supported by people that I know who also have this condition. It’s been a tough road. But as we all know, the road keeps going. Unless some asshole blocks it.

Multiple sclerosis is an autoimmune disease that occurs when the immune system begins to attack the sheath that protects nerve fibers, making it difficult for the brain to communicate with the rest of the body. MS often makes it hard to walk and move and can lead to paralysis in the legs for some.

“So now I ask for privacy. As I go through this thing,” she requested in the following tweet. Applegate was previously diagnosed with breast cancer in 2008 and underwent a bilateral mastectomy.

As one of my friends that has MS said “ we wake up and take the indicated action”. And that’s what I do. So now I ask for privacy. As I go through this thing. Thank you xo
