She then brought up Ehlers-Danlos Syndrome, a rare group of inherited connective tissue disorders.
“I have that. I’m on that spectrum, the hypermobile spectrum,” Clarke said.
She also named Mast Cell Activation Syndrome, known as MCAS, as one of the related issues she has dealt with.
“There are things that are a repercussion of having that, MCAS being one of them, Mast Cell Activation Syndrome,” she explained. “It basically just means I have a lot of inflammation ’cause my body thinks it’s allergic to everything.”
A glamorous acting career, apparently, does not come with a warranty for the central nervous system. Rude, but medically unsurprising.
What are Ehlers-Danlos Syndrome and MCAS?
Ehlers-Danlos syndromes, often shortened to EDS, are rare inherited conditions that affect connective tissue. That tissue helps support the skin, tendons, ligaments, blood vessels, internal organs and bones.
Clarke described herself as being on the hypermobile spectrum, which commonly involves unusually flexible joints and can be associated with pain, instability and other symptoms.
MCAS is a condition involving mast cells, part of the immune system. In people with MCAS, chemicals known as mast cell mediators can be released too often, in excessive amounts, or in response to triggers that would not usually be considered harmful, such as certain foods or environmental chemicals.
That overreaction can cause symptoms across different parts of the body, which helps explain Clarke’s description of widespread inflammation and feeling as if her body is “allergic to everything.”
She credited a “remarkable doctor in America” with helping her finally manage the problems.
“And I feel great in a way that I didn’t realise I could feel great,” she said, adding that she had previously accepted the symptoms because they were not stopping her life “to a massive degree.”
How her brain injuries unfolded during Game of Thrones
Clarke’s first aneurysm happened between filming the first season of Game of Thrones and the show’s release. She was working out at a gym with her trainer when she was hit by what she later described as an “unbearable headache.”
She was rushed to hospital, where doctors worked to identify what had happened. The diagnosis was a subarachnoid haemorrhage, a serious type of bleeding around the brain.
Only weeks later, Clarke was back doing press for season one. She has previously said she was determined to move past the life-threatening event, partly because she feared she “would be fired.”
In 2013, a routine follow-up brain scan detected a growth in her brain that had “doubled in size.” During surgery, the planned procedure failed, and Clarke suffered a “massive bleed.” Surgeons then received permission to open her skull for an immediate, more invasive operation to save her life.
“The recovery was even more painful than it had been after the first surgery,” she said when she first shared the full story publicly.
Why Clarke’s update matters
Clarke’s latest comments add another layer to a story many viewers first understood as a dramatic survival account. What she is describing now is the quieter aftermath: the years spent functioning, working and appearing fine while the body keeps sending invoices.
Her decision to speak about brain injury recovery, EDS and MCAS also fits with the work she has done through SameYou. The charity focuses on the kind of rehabilitation that can be overlooked once a patient survives the immediate medical emergency.
For audiences who knew Clarke mainly as Daenerys Targaryen, her public honesty has made the contrast sharper. Behind one of the most visible roles in television, she was managing fear, recovery and the pressure to keep working.
Now, she says, she feels better than she realised was possible. After years of treating “fine” as good enough, that is not a small update.
