EEG SCANS MAY BE KEY TO COMMUNICATION FOR VEGETATIVE PATIENTS

By Rebecca Boyle June 22, 2010

A study by British and Belgian（比利时的） researchers shows some patients declared brain-dead can still respond to commands. They think EEG（脑电图） machines could help these patients communicate once again.

Brain-wave scanners might make it possible to communicate with people who are considered brain-dead, according to a new study reported in the Economist（作者在这里注明了消息来源）.

A couple of recent studies have shown that a small minority of vegetative patients（植物人患者） might be more aware than they seem. Now, Damian Cruse, with the Medical Research Council’s Cognition and Brain Sciences Unit in Cambridge, UK, thinks EEG machines will be able to help these patients communicate.

The team asked six healthy volunteers to wear electroencephalography (EEG) devices, which connect electrodes（电极） to a person’s head. They were asked to respond to an audible tone（可听见的声音） by imagining that they were squeezing（紧握） their right hands or wiggling（摆动） the toes of both feet. The researchers found that the volunteers’ brain responses were clearly different – the hand-squeezing activated the left-hand side of the brain and the toe-wiggling produced a response in the center of the brain.

They then tested the procedure on a patient with locked-in syndrome（闭锁综合征）, who was almost completely paralyzed（瘫痪） but retains（保持） some control of his eye movements. His brain responses were the same. Finally, they tested the procedure on a patient who had been declared vegetative two years earlier. They watched the EEG signals and were able to deduce which movement the patient was imagining.

The same team had studied 23 vegetative patients over four years and found four patients were able to consistently（一直，一致） respond to yes or no questions by changing their brain activity. They were asked to imagine playing tennis when they wanted to give one response, or walking around the house when they wanted to give the other.

Since the patients were responsive, they are not technically vegetative, the researchers say. Proof that they can communicate – that they’re not brain-dead – would have major implications for family members’ and doctors’ decisions about their care.
