If you or someone you know has multiple sclerosis (MS), you probably know the wide variety of symptoms the disease can cause—things like impaired speech, extreme fatigue, cognitive problems, pain and more.

Actress Selma Blair talked about her diagnosis and daily struggles with her MS on Good Morning America a few years back. At the time, she had extreme spasmodic dysphonia, a side effect of MS that can alter your speech, so the interview gained lots of attention and intrigue.

In the interview, she talked about everything from her exhaustion with being a single mother with MS to what it felt like when she was officially diagnosed and more. Though she physically felt awful, she was hopeful for the future.

Since then, Blair has come on Good Morning America once more, and she’s doing so much better. The reason why will all be explained in her new documentary “Introducing, Selma Blair,” where she opens up about how she embraces her MS. The documentary will come to theaters October 15 and streams on Discovery+ starting on October 21.

In the documentary, and on her recent appearance on Good Morning America, she discusses how in 2019, she received an experimental treatment stem cell transplant—a procedure that isn’t yet FDA approved. Additionally, she had to undergo several rounds of chemo to help “reboot” her immune system.

The decision to get a procedure like that was no easy task. “I kinda got to a critical point and my nervous system and more symptoms and I couldn’t stay awake,” Blair said. “I was mortally afraid of chemo my whole life. I’m someone that’s always gone holistic when I can.”

However, after her doctor convinced her to do just one round of chemo, she realized how much better she felt. After completing the treatment in its entirety, her brain is free from forming new lesions. She does experience some volume loss in her speech and movement areas, but she’s on medicine to help.

“I chose this as a marker in my life to want to live, to want to be a person that can show other people with chronic illness, disabilities, an injury they couldn’t get over, a hit,” she said. “I just took a hit. And we take hits. … And that resilience is possible.”
