People in a coma can not think and interact with its environment, claimed the British and beligijski scientists at the New England Journal of Medicine.
coma People in a coma can still think and communicate People in coma may think and interact with its environment, claimed the British and beligijski scientists at the New England Journal of Medicine. Living without a camera This finding pobuduje range of scientific and ethical questions about how to handle patients who are in a coma. Researchers studied a 29-year-old Belgians that in 2003. year had a serious car accident after which he remained in vigilnoj coma or persistent vegetative state. The patient in this state is not on life support, and when not sleeping, lying eyes open, but shows no signs of consciousness. However, a group of scientists led by Dr Adrian Owen from Cambridge University and Dr. Steven Laureys of the University Liege revealed that the patient can interact with its environment. Brain activity Using sophisticated devices for functional magnetic resonance imaging, scientists have monitored the activity of his brain while he was asking a simple biographical questions. How to answer "yes" or "no" in the brain manifested as signals that are too similar to each other to get them on the findings might vary, scientists have come up with "codes" for the answers. They told the patient to think about playing tennis when the answer is "yes" and when the answer is "no" to some thinking about walking around the house. In fact, thinking about those two actions activates different parts of the brain and can be easily detected by MRI. Then the patients were asked six simple biographical questions, the type that the name of his father John and mother Mary. To their surprise the patient on all six questions answered correctly. Happy family - We were zacudeni when we see the results. He was able to correctly answer the question simply by thought - said Dr. Owen. He said that the family of a young patient whose identity is not known to the public was delighted when he realized that the son can not communicate with the environment through thought. Otherwise, Adrian Owen is one of the leading scientists in the research of anyone. That was 3.5 years in the journal Science published a study about a young patient in a coma that she could hear and understand their environment. Despite decades of research, scientists still know little about the situation where anyone can come to spontaneous recovery. The fact of the debate - One fifth of patients in persistent vegetative state has a fully functional brain. Obviously, this should be taken into account when discussing whether to allow these patients to die - said Owen. His discovery will have significant implications in the ethical debate about whether patients who are in a multi-year coma to enable them to die.
