Not "vegetables" after all
An article from today's Washington Post describes amazing work that demonstrates that some patients in a so-called "vegetative state" are in fact quite conscious:
an international team of scientists decided to try a bold experiment using the latest technology to peek inside the minds of 54 patients [in "vegetative states'] to see whether, in fact, they were conscious.One by one, the men and women were placed inside advanced brain scanners as technicians gave them careful instructions: Imagine you are playing tennis. Imagine you are exploring your home, room by room. For most, the scanner showed nothing.
But, shockingly, for one, then another, and another, and yet two more, the scans flashed exactly like any healthy conscious person's would. These patients, the images clearly indicated, were living silently in their bodies, their minds apparently active. One man could even flawlessly answer detailed yes-or-no questions about his life before his trauma by activating different parts of his brain.
"It was incredible," said Adrian M. Owen, a neuroscientist at the Medical Research Council who led the groundbreaking research described in a paper published online Wednesday by the New England Journal of Medicine. "These are patients who are totally unable to perform functions with their bodies -- even blink an eye or move an eyebrow -- but yet are entirely conscious. It's quite distressing, really, to realize this."
...
"This should change the way we think about these patients," said Nicholas D. Schiff, an associate professor of neurology and neuroscience at Weill Cornell Medical College in New York City. "I think it's going to have very broad implications."
The pressing challenge now is to figure out a way to communicate effectively with these patients, both as part of their treatment and as a means of allowing them contact with the outside world.
