Coma

A coma is a deep state of unconsciousness. It can occur as a complication of an illness, exposure to a drug, alcohol, or toxin, or as a result of injuries, such as head trauma. A coma is a medical emergency.

People in a coma generally recover but some don't. It can be very difficult to predict recovery when a person is in a coma. Sometimes a coma is followed by a persistent vegetative state.
