Bella Ramsey first gained recognition in the industry for their portrayal of Lyanna Mormont in the HBO fantasy TV series Game of Thrones. One of their most popular roles is as Ellie in the post-apocalyptic TV series, The Last of Us.
Ahead of the release of The Last of Us season 2, Ramsey opened up to Vogue in an interview on April 11, 2025, about their autism diagnosis. They said:
"I got diagnosed with autism when I was filming season one of The Last of Us."
As stated in the article, during the show's shooting in Canada, a crew member with an autistic daughter assumed that the actress also had it. Following formal psychiatric assessment and diagnosis, it was confirmed that Bella Ramsey had it.
Elsewhere in the interview, they claimed that sharing their autism diagnosis is liberating for them:
"It enables me to walk through the world with more grace towards myself about not being able to do the easy, everyday tasks that everyone else seems to be able to do."
They further revealed that autism has helped them get better at acting:
"I’ve always been watching and learning from people. Having to learn more manually how to socialize and interact with the people around me has helped me with acting."
