What does this mean?

A coma is a deep state of unconsciousness from which it is impossible to be aroused. The cause of the coma may be as a result of another illness such as a stroke, infection, and very low blood sugar or may be brought on by a serious accident.

The coma needs to result in permanent damage to the nervous system in order to be covered by the definition.
