Selma Blair reveals that she's been diagnosed with multiple sclerosis

Blair’s post was openly emotional, thanking friends like Sarah Michelle Gellar and Freddie Prinze Jr. for their support, as well as all the cast and crew of Another Life, who’ve been helping her manage her disability while working on the show. “I am disabled.” Blair writes. “I fall sometimes. I drop things. My memory is foggy. And my left side is asking for directions from a broken gps. But we are doing it.”

Blair—whose other recent projects include a role that promised to be one of the sporadic highlights of the very weird Heathers TV reboot—plays “Harper Glass” on the Netflix sci-fi series, a “media influencer” and journalist hoping to break an Earth-shaking story through sheer force of will.

Multiple sclerosis (which targets the insulating protection on neural axons, preventing them from transmitting signals throughout the body) comes in many forms, and presents patterns of symptoms and attacks that differ widely from patient to patient. Roughly 2.3 million people are affected by the condition across the globe.
