She was transferred from the hospital to Walton Neurological Centre, where she was put into a medically induced coma.
Her family were told it was "touch and go" if she would survive.

Her ward manager, Sophie Elwell, said the mum-of-two is still in an induced coma after being treated, and is currently stable.
Sophie said: "She had just finished her lunch and left the room with a couple of other staff, having a giggle as she usually does.
"She complained of a headache and moments later she collapsed onto the floor. Her heart did stop beating and she was resuscitated."
Colleagues said Nicky had come into work her "usual happy and mischievous" self.
Her friends at the hospital are said to be devastated by what happened.
Nicky is described as 'the most vibrant and colourful lady' by her work friends.
"She joined us 18 months ago and she is just brilliant. Nicky is the most vibrant and colourful lady, she smiles with a twinkle in her eye," Sophie said.
"She's always up to mischief, but in the best way. She's a huge part of our team and is extremely loved and cared for by her family.
"She loves Christmas and to know she might be in hospital at this time of year and with the pandemic still going on is heartbreaking."
With the permission of Nicky's husband, siblings and two children Sophie and the ward 18 team have set up a GoFundMe page for Nicky.
The money raised will go towards Nicky's family to assist in her recovery after her brain injury.
So far the page has had 99 donations raising a total of £1,710.
