What are the symptoms of coma?
Coma is a state of prolonged unconsciousness that can be caused by a variety of problems — traumatic head injury, stroke, brain tumor, drug or alcohol intoxication, or even an underlying illness, such as diabetes or an infection.
Coma is a medical emergency. Swift action is needed to preserve life and brain function.
Doctors normally order a series of blood tests and a brain scan to try to determine what's causing the coma so that proper treatment can begin.
The signs and symptoms of a coma commonly include:
- Closed eyes
- Depressed brainstem reflexes, such as pupils not responding to light
- No responses of limbs, except for reflex movements
- No response to painful stimuli, except for reflex movements
- Irregular breathing
