I am not an expert and have no medical qualifications but I found this online.
Does anyone recover from brain death?
Sadly, no one has ever recovered after being
declared brain dead.
What does brain death look like?
Brain dead patients look asleep, but they are not.
They do not hear or feel anything, including pain.
This is because the parts of the brain that feel,
sense, and respond to the world no longer work.
In addition, the brain can no longer tell the body
to breathe.
Because the brain cannot control breathing,
breathing must be done by a machine, called a
ventilator. As long as the ventilator is working,
the heart will keep beating.
So I am convinced that Archie does not feel anything at all.
I agree that there must be a media silence on this topic, and I hope that Hollie is able to process the whole situation and be able to spend time with Archie in total privacy.
