"I am in the really, really, really small minority of people that can survive that."
She added that scans of her brain show that there is "quite a bit missing."

She explained: "Because as soon as any part of your brain doesn’t get blood for a second, it’s gone. And so the blood finds a different route to get around but then whatever bit it’s missing is therefore gone."
The 35-year-old is currently starring in a a two-and-a-half hour theatre adaptation of
The Seagull and pointed out how remarkable it is that she is able to remember all her lines for the lengthy play despite the aneurysms.
She also said how starring as Daenerys Targaryen when she had the brain injuries managed to help her deal with the ordeal, saying: "It was incredibly useful to have the show to sweep me up and give me that purpose."
It's not the first time she has spoken about how important her
Game of Thrones role was in helping her deal with the trauma.
Back in 2019, Clarke shared never-before-seen pictures with
CBS Sunday Morning from her time in hospital recovering from one of the aneurysms.

She told the US broadcaster that it was "much harder to stay optimistic" after the second one.
But she added: "You go on the set and you play a badass character, and you walk through fire, and you speak to hundreds of people, and you're being asked to be - to work as hard as you possibly can.
"And that became the thing that just saved me from considering my own mortality."
