Signs & symptoms

Signs and symptoms of coma include closed eyes, no responses of limbs and to painful stimuli, except for reflex movements, and depressed brainstem reflexes, such as pupils not shrinking in response to light.


Because it’s impossible to question people in coma, doctors must rely on physical clues and information provided by their friends and families. Some of the information the doctors would have to investigate include: events leading up to the coma, details about how the patient lost consciousness, signs before losing consciousness. Physical exam, laboratory tests and brains scans are also part of the diagnosing process to assure the mental status of the patient.


Treatment of a coma depends on the cause. Doctors may give breathing assistance, intravenous medications and other supportive care.
