Brain dysfunction: Coma is the term used to describe a person's level of consciousness, or awareness. It is not a disease itself. A coma state can be caused by injury, disease, chemicals, or temporary lack of oxygen or blood flow to the brain. If a person lost consciousness and did not "wake up", they would be described as being in a coma. A coma can be temporary or permanent, depending on the cause and severity.
