NEW YORK - A brain-damaged man who could communicate only with slight eye or thumb movements for six years can speak again, after stimulating electrodes were placed in his brain, researchers report.
The 38-year-old also regained the ability to chew and swallow, which allows him to be spoon-fed, rather than relying on nourishment through a tube in his belly.
The man's brain was injured during an assault, he spent six years with only occasional signs of consciousness and no useful movement of his limbs. In an experiment, researchers implanted electrodes in his brain for a procedure called deep brain stimulation, which is routinely done for Parkinson's disease and some other illnesses.
They turned the electrodes on and off over six months to test their effect, and reported the results in Thursday's issue of the journal Nature. The man, who was not identified at the family's request, now has them on throughout the day.
Experts called the report exciting but cautioned that the approach must be tested in more people before its value can be known. The researchers have already begun a study of additional patients.
Before the electrodes were implanted the man was in what doctors call a "minimally conscious state." That means he showed only occasional awareness of himself and the environment. In a coma or vegetative state, by contrast, patients show no outward signs of awareness.
There are no firm statistics on how many Americans are in a minimally conscious state, but one estimate suggests 112,000 to 280,000. Doctors may try medications to improve their condition but no drugs have been firmly established as helpful.
The man described in the Nature study speaks in a breathy but audible voice, said Dr. Joseph Giacino, a co-lead author. He does not initiate conversations but can reply to others, typically with one to three words, said Giacino, of the JFK Johnson Rehabilitation Institute in Edison, N.J.
Several weeks ago he recited the first half of the Pledge of Allegiance without assistance, Giacino said.
The man also recovered some movement. He can demonstrate motions such as brushing his teeth, said study lead author Dr. Nicholas Schiff of Weill Cornell Medical College in New York. He can't actually carry out that task because the tendons in his arms contracted after years of immobility.
"He is still totally dependent and severely disabled," Schiff said.
But the treatment has helped him, the man's mother said in a statement. "Now, my son can eat, express himself and let us know if he is in pain. He enjoys a qualify of life we never thought possible," she said.
Dr. James Bernat, a professor of neurology at Darmouth Medical School who didn't participate in the new work, called the Nature report exciting and important. Further study is needed to shed light on how many patients would respond and how to identify the minimally conscious patients with the best chance of being helped, he said.
He noted that a similar treatment did not help Terri Schiavo, the Florida woman in a vegetative state whose care triggered national controversy before her death in 2005. That's the typical outcome for electrical brain stimulation in vegetative states, he said.
Dr. Ross Zafonte of the University of Pittsburgh, who also was familiar with the study results, agreed that "we need to know more" and said the approach is "very interesting and holds great promise."

Semantics is right. The whole controversy seems to stem from a misunderstanding about U.S. Representative Michael Bilirakis and his qualifications to nominate one of his constituents for the Nobel Prize in Medicine, not on the work of Dr. Hammesfahr himself.
Why don’t you state your position now to clarify it for everyone in the thread?

No problem. I stated while it was happening that MS should turn custody over to Terri’s family. He wanted out, the family wanted her. Likely StAnDeliver, with his/her research skills could link to the exact post, but chose (for some reason) to skip over that one, as I guess it did not fit in with his/her preconceived notions about where I stood on the issue.
Does that answer your question adequately?
life. love. RIP.

It’s funny because it’s true. I stopped laughing when I realized that liberals are also too broad-minded to take the side of their own country in a war.
Thank you for being up front about it. I agree with your stated position on what should have happened with Terri.
I wish more people agreed with us, dmz.
BTTT!
Always. Righteousness is the blessing conferred by being right, and thus, dispassionate about the discourse that follows. Fortunately (even though you may not think so), the Terri Schiavo's are rare, because the vast majority of Americans cherish life on every level of experience.
