Game of Thrones actress Emilia Clarke was only 24 when she suffered a stroke following a workout.
Known for her role as Daenerys Targaryen in the HBO fantasy series, Clarke felt a severe headache, began vomiting and then collapsed in the bathroom of her gym.
At the time, she was the definition of youthful fitness and certainly not the sort of person you would expect to have a stroke.
Her type of stroke is known as a subarachnoid haemorrhage, caused by bleeding in the area between the brain and the tissues that cover it. It is often the result of a ruptured aneurysm – a ballooning section of a blood vessel with a fragile wall – as it was in Clarke’s case.
It is less common than some type of strokes but not rare, estimated to cause around 5 per cent of all strokes.
