My question..., however, would....you ...consider somebody a human if their brain were removed, destroyed, and their body sustained only by machine.
If it looks like a duck, walks like a duck and quacks like a duck......
However, if you're asking if somebody could be considered a "viable" human being, then at current levels of medical technology such a person would no longer be "viable", just a carcas (sort of like the embryo after you abort it, btw). Now, if we could grow a new central nervous system to put in place of the old one...then that person would be a "patient".
