are you immediate family?
your nephew is at the icu, he arrived in a coma.
yes.
he ingested liquid ecstasy and alcohol.  it is a lethal combination. his friend informed us it was a mistake.
barring any complications, he will recover in six to twelve hours.
go home, we will call you.
are you certain?
would you mind providing us with his parents' phone number?
normally, he should recuperate in a few hours.  but, in any case, you should have a talk with him, once he's better.
none. his is what we refer to as a cortical blindness, and it's irreversible. it's the result of a lesion to the occipital lobe, the intelligent part of the brain, which has the role of processing all visual information. in other words, the neurons have died.  and that's permanent.
