Coma and brain death

The difference between coma and brain death is that patients can recover from coma. They can't recover from brain death. Kind of like the difference between having a cold, and being Welsh.

Coma

A coma is a deep state of unconciousness. Unlike sleep, they cannot wake up, respond to pain or perform voluntary actions. The most widely recognised way of diagnosing a coma is through the Glasgow Coma Scale:

Motor

1. Makes no movements.
2. Extension on pain
3. Abnormal flexion on pain.
4. Withdrawal/flexion on pain.
5. Localises painful stimuli.
6. Moves on command.

Verbal

1. Makes no sounds.
2. Makes noises.
3. Makes words, but no sense.
4. Confused conversation.
5. Normal conversation.

Eyes

1. Does not open eyes.
2. Opens eyes to pain.
3. Opens eyes to voice.
4. Opens eyes spontaneously.
