Often, this is called a coma or being in a comatose state.Other changes in awareness can occur without becoming unconscious. Medically, these are called "altered mental status" or "changed mental status." They include sudden confusion, disorientation, or stupor.Unconsciousness and any other SUDDEN change in mental status must be treated as a medical emergency.If someone is awake but less alert than usual, ask a few simple questions, such as:What is your name?What is the date?How old are you?Wrong answers or an inability to answer suggest a change in mental status.
