What is a Persistent Vegetative State?
The term refers to a condition caused by a brain injury. The victim is unable to respond to his or her surroundings and is not aware of anything, even though the eyes may open periodically. It is similar to a coma in that the person is unresponsive, but it is a permanent condition. A head injury, stroke or other events may result in this condition and a person may be kept alive indefinitely in this condition by artificial means.
