What is CoMA?
COMA is a sleep-like state in which the injured person does not open his/her eyes, does not speak, and cannot obey commands like “Stick out your tongue!” or “Hold up one finger!”. There are several levels of coma. A number scale called the Glasgow Coma Scale is often used to describe the responses of people in coma. There is nothing magic about this scale, it just attaches numbers to the responsiveness of the head injured person in terms of eye-opening, speaking, and moving his/her extremities. People are usually no longer considered to be in coma if they open their eyes, speak, or can obey simple commands.
