Christina Applegate Addresses Health Concerns Amid MS Battle

Health Journey

Christina Applegate shared she was diagnosed with multiple sclerosis in 2021.

"Hi friends. A few months ago I was diagnosed with MS," she shared on her social media channels that August. "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 a--hole blocks it."

First Public Appearance

Early Symptoms

Christina believes her MS journey actually began "six or seven years" before her 2021 diagnosis.

"I noticed, especially the first season [of Dead to Me], we'd be shooting and my leg would buckle," Christina explained during a March 2024 interview on Good Morning America. "I really just put it off as being tired, or I'm dehydrated, or it's the weather. Then nothing would happen for months, and I didn't pay attention."

By the time she was shooting the Netflix series' third and final season, the actress said she was "being brought to set in a wheelchair."

"I couldn't move that far," she recalled, "so I had to tell everybody because I needed help."

Making Moves

Strong Statement

Joined by her daughter Sadie Grace LeNoble, Christina had a simple message for multiple sclerosis while attending the 2023 SAG Awards: "F U MS."

And she's not the only one experiencing strong feelings towards the illness. "In my situation, Sadie only knew me as healthy and a runner and a Pelotoner and a dancer—and she only knew that," Christina explained to friend Jamie-Lynn Sigler on an August 2025 episode of their MeSsy podcast. "So then when this came about in 2021, she was, like, stoic about it."

Yet, "I see her look at me when I’m in bed," Christina continued, "and can't quite move or, I want to go say goodnight to her in her room but I can’t quite get down the hallway for whatever reason my legs aren’t working that day." 

The whole experience has "broken" her teen, Christina noted. "It was like losing the mom she had to this f--king thing. And the more she’s gotten older now, I think the more it’s hurting her."

Just Jokes

After a receiving standing ovation at the 2023 Emmys, the Married...With Children alum quipped, "You're totally shaming me with disability by standing up."

Healing Through Humor

"I make these jokes because if I don't, I'll suffocate," Christina shared on a March 2024 episode on Armchair Expert, explaining why she often pokes fun at her condition. "I'll be done."

So, yes, she's going to talk about the fact that she's already purchased burial plots. 

"My friend and I are going to go take a picnic there," Christina revealed on a March 2026 episode of NPR's Wild Card. "It's really pretty where it is." She just has to pick out a tree "'cause it's really sunny," she continued. "And I want my visitors to not be sweating."

MS On Her Mind

"I have 30 lesions on my brain," she noted on Armchair Expert. "My biggest one is behind my right eye, so my right eye hurts a lot."

Legions are caused by the immune system attacking the myelin sheath around nerves, according to the Multiple Sclerosis Trust.

Getting Candid

Christina hasn’t held back when it comes to sharing her journey. 

"It sucks," the Anchorman actress told late night talk show host Jimmy Kimmel of her daily struggles with MS. "I'm not going to lie. I think anyone who has MS isn't going to be like, 'This is the best thing that ever happened to me!'"

Besides, she'd taken that tack when discussing her breast cancer battle back in 2008. "I went out, and I was the good girl talking about 'Oh, I love my new boobs' that are all scarred and f--ked up. What was I thinking?" she said on Armchair Expert. "Everything I was saying was a freaking lie. It was me trying to convince myself of something, and I think that did no service to anyone." 

While she started a foundation and "raised millions of dollars for women to get MRIs who were at high risk," she noted, "at the back of it, I was taking off my bra and crying every night. And I wish that I had said that."

In Her Bubble

When talking about her day-to-day life with the disease, Christina told Good Morning America in March 2024, "I live kind of in hell."

"But I might get to a place where I function a little bit better," she added. "Right now, I'm isolating, and that's kind of how I'm dealing with it—by not going anywhere because I don't want to do it. It's hard." 

The Sweetest Support

Christina credited her Sweetest Thing costar Selma Blair—who was diagnosed with MS in 2018—for urging her to get tested for the disease.

"She said, 'You need to get checked for MS,'" Christina recalled during her GMA interview. "If not for her, it could've been way worse."

Friendship Never Dies

Christina confirmed that Dead to Me will likely be her last onscreen credit, telling Vanity Fair in May 2023, "I can’t even imagine going to set right now."

"I’m probably not going to work on-camera again, but I'm so glad that I went out with someone who is by far the greatest actress I’ve ever worked with in my entire life," she said of costar Linda Cardellini, "if not the greatest human I’ve ever known.
