What is a coma?

Answer 1

Coma is an extended period of unconsciousness from which a person cannot be aroused even with the most painful stimuli. Coma is not a disease. It is a symptom of a disease or a response to an event, such as a severe head injury, seizure or metabolic problem. Most comas do not last longer than four weeks. Some people in a coma shift to a persistent vegetative state, in which breathing, maintaining normal blood pressure, digesting and eliminating foods continues without the patient's awareness. The vegetative state can last for years or decades. The outcome of a coma ranges from full recovery to death. Whether a person recovers, and to what extent, depends upon the cause of the coma and the type and extent of the brain damage.

Answer 2

When you find out let the medical profession know. There's so much that we don't know about a "coma" most people that come out of them, whether they've been in one a few days or years say the same "they thought they fell asleep for a few moments" that all.
I've know people that had serious damage to they're medulla spine, at the base of their brain and never regained consciousness but, that a different story. I'm speaking about a coma where a person just slips into one for some unknown reason. We just don't know what's going on.

Answer 3

A deep sleep where the person... wait... I think there are different types of comas! lemme check......:
"In medicine, a coma (from the Greek koma, meaning deep sleep) is a profound state of unconsciousness. A comatose patient cannot be awakened, fails to respond normally to pain or light, does not have sleep-wake cycles, and does not take voluntary actions. Coma may result from a variety of conditions, including intoxication, metabolic abnormalities, central nervous system diseases, acute neurologic injuries such as stroke, and hypoxia. It may also be deliberately induced by pharmaceutical agents in order to preserve higher brain function following another form of brain trauma."

Answer 4

It is a very deep state of unconciousness. A patient in a coma cannot be awakened, and fails to respond to pain or light.
