What are the risks of a heart transplant?
Need a new body part? Tissue engineers are now growing human bladders, lungs, and other organs in the lab with the hope that, someday soon, such organs may replace diseased organs in people. Transplant surgeons, for their part, routinely place donated kidneys, hearts, and other organs into patients whose own organs are failing.
They have transplanted hands, arms, even, famously, a face. This has left me wondering, where does the brain come into all this? Will we someday grow replacement brains or do whole-brain transplants? Three questions leap to mind: Some experts have actually put their minds to it.
And I felt a little sheepish when I called experts to ask them about it. Would they dismiss me out of hand, beseeching me not to waste their time with a subject best left to science-fiction writers? But with science and medicine advancing at a dizzying pace, and with questionable medical procedures of the past as cautionary tales, it seemed like a subject worth addressing, if only perhaps to reject it as untenable, unconscionable, or simply too ghastly to contemplate.
First of all, why? What medical justification could exist for growing a new brain, or part of one, and placing it in someone whose own brain, or part of it, was removed? Would it be nice to be able to regrow the appropriate regions?
Talk to any paraplegic or quadriplegic out there. They would love to have new cervical neurons or brain-stem regions. Trying to make or reestablish tiny connections in the brain, even between single neurons, is closer to reality than growing whole brains, tissue engineers say.
Under what scenario would we consider that? About a decade ago, Dr.
Robert White, a neurosurgeon at Case Western Reserve University, received a burst of media attention by advocating what he called "whole-body transplants" for quadriplegics.
And, perhaps because of the yuck factor, he preferred to call such an operation a whole-body transplant. Quadriplegics often die prematurely of multiple-organ failure, White said. Brain-dead patients already serve as multiple-organ donors, so a whole-body transplant is not as macabre as it might at first sound, White argued.
Could surgeons detach a living human head brain included and place it on the living body of a donor? White, who is now retired after 60 years as a brain surgeon but is still active as a writer and consultant. Could we, technically speaking? Could we grow a whole human brain, or even part of one, in a laboratory?
But certainly to replace a lobe today, that would be science fiction with current technology. The question is, will that rebuild a brain, including everything you need for mind-brain function, or even a piece thereof?How Brain Transplant Is Done and Important Details About the Process PAGES 2.
