Actor Christina Applegate said late Monday on Twitter that she has been diagnosed with multiple sclerosis.

Its been a strange journey. But I have been so supported by people that I know who also have this condition, wrote the Bad Moms star, who said she received confirmation of her diagnosis a few months ago.

Its been a tough road, continued Applegate, 49. But as we all know, the road keeps going. Unless some asshole blocks it.

In a second tweet, Applegate recalled one of her friends with the disease telling her that we wake up and take the indicated action.

And thats what I do, she added.

Applegate asked for privacy as I go through this thing.

Multiple sclerosis, or MS, attacks the central nervous system .

The resulting nerve damage impairs communication between the body and the brain. Symptoms include tremors, fatigue, vision loss, slurred speech and weakness in limbs. It typically affects more women than men.

Some 2.3 million people have been diagnosed with the disease worldwide. Most people with MS have a normal life expectancy.
