The family of Archie Battersbee have submitted an application to the European Court of Human Rights (ECHR) to hold off on withdrawing his life support.
The 12-year-old has been in a coma after he was discovered collapsed in the family home in Southend.
Speaking exclusively to Sky News, his mother, Hollie Dance has said that she has been contacted by doctors in both Japan and Turkey who say they have medical interventions that will help him recover.
She continued, saying: “We are very relieved. We are having to battle every decision with the hospital.
"We now hope and pray that the ECHR will look favourably on the application. We will not give up on Archie until the end."
What was the online ‘black out challenge’ that Archie took part in?
According to the Centres for Disease Control and Prevention in the USA these so-called blackout challenges have resulted in the deaths of more than 80 people.
The challenge encourages individuals to hold their breath until the blackout.
The concept was first heard of back in 2008 but with the popularity of TikTok amongst younger people, it has reemerged again in recent years.
