The Coma State
A coma is a profound or deep state of unconsciousness. The affected individual is alive but is not able to react or respond to life around him/her. Coma may occur as an expected progression or complication of an underlying illness, or as a result of an event such as head trauma.
Coma is a state of brain function. The human brain performs at different levels of consciousness. Each level does not have distinct boundaries, but rather, at one end blends into the level above it and at the other, blends into the level below it. At the highest level of performance the mind is perceived as alert, sharp, quick to respond to varying forms of input. Through a gentle phasing down, the brain may become progressively less responsive until, at the lowest level of function, the brain is in a state of coma. This represents the last state before death. This state most frequently occurs abruptly rather than in phases, usually followed by a progressive recovery.
