In more severe cases a coma may last for over five weeks, while some have lasted as long as several years. After this time, some patients gradually come out of the coma, some progress to a vegetative state, and others die. Some patients who have entered a vegetative state go on to regain a degree of awareness. Others remain in a vegetative state for years or even decades (the longest recorded period being 42 years). The outcome for coma and vegetative state depends on the cause, location, severity and extent of neurological damage.
Research shows that a comatose patient's outcome relates very closely to his or her Glasgow Coma Scale score. The majority of people (87 percent) who score a three or a four on the scale within the first 24 hours of going into a coma are likely to either die or remain in a vegetative state. On the other end of the scale, about 87 percent of those who score between 11 and 15 are likely to make a good recovery [ref].
