• Physicians have no tests to determine when or if a person will come out of a coma.
  
  
• Physicians have are not able to provide treatment specifically to make a person come out of a coma.
  
  
• It is important to evaluate a person who is comatose to see if they respond in some manner or if they are not responding at all to the environment around them.
  
  
• Persons in a coma may seem to “asleep” because they are unable to be woken or alerted.
  
  
• Many times while in a deep coma, a person is unable to move at all, even to painful stimuli. The coma patient may also be unable to make any voluntary actions or exhibit any meaningful responses.
