Résumé

A coma is a state of unconsciousness where a person is unresponsive and cannot be woken. A severe head injury or a condition that affects the brain such as a stroke is two possible causes of a coma. A person can also be in a coma as a result of alcohol intoxication. Extreme changes in blood sugar levels in people with diabetes - very low blood glucose levels (hypoglycemia) or very high blood glucose levels (hyperglycemia) - can also cause coma.
You may find the following information useful if you have a friend or a loved one who is in a coma. Someone who is in a coma has minimal brain activity. They are alive but cannot move or be woken. Their potential for recovery will depend on the cause of the coma. A person in a coma will often be unresponsive to their environment. They may not be able to hear voices or feel pain. However, a person in a coma may have some awareness of their surroundings.
Every coma experience is unique. Occasionally, a person in a coma may open their eyes, grimace or make a noise. They may not be aware of these movements or have any control over them. Being in a coma means the person has a low level of consciousness. Their level of consciousness will depend on how much of their brain is functioning, which may change over time. For example initially a person may be in a very deep coma where they are unresponsive to pain, before gradually recovering to a lighter coma, where they respond to pain.
They may continue improving and eventually they may become aware of their surroundings and begin to communicate. The ability to make a clearly conscious response to external instructions indicates that the person is no longer in a coma. Doctors score a person's level of consciousness using a tool called the Glasgow Coma scale. The Glasgow Coma Scale assesses three things:1. Eye opening- a score of one means no eye opening, and four means opens eyes spontaneously2.
Verbal response to a command - a score of one means no response, and five means alert and talking3. Voluntary movements in response to a command - a score of one means no response, and six means obeys commandsA higher score on the scale suggests that less brain function has been lost. A score of eight or less is often used to mean that someone is in a relatively deep coma. Recovery depends on how much of the person's brain has been affected by the underlying condition or injury.
Generally the longer the person has been in a coma, the poorer the outlook. People don't usually suddenly 'wake up' from a coma, but tend to come round gradually and regain brain function over time. When a person comes out of a coma, they may be agitated and confused. They may need to be sedated for their own safety. Some people will make a full recovery and be completely unaffected by the coma.
