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

Causes

Many types of problems can cause a coma.

Some examples are:

  •  Traumatic brain injuries.
  •  Stroke.
  •  Tumors.
  •  Diabetes.
  •  Lack of oxygen.
  •  Infections.
