The symptoms of a coma commonly include: 1. Closed eyes. 2. Depressed brainstem reflexes, such as pupils not responding to light. 3. No responses of limbs except for reflex movements. 4. No response to painful stimuli except for reflex movements. 5. Irregular breathing.
Many types of problems can cause a coma. Some examples are: 1. Traumatic brain injuries.These are often caused by traffic collisions or acts of violence. 2. Stroke.Reduced or stopped blood supply to the brain, known as a stroke, can result from blocked arteries or a burst blood vessel. 3. Tumors.Tumors in the brain or brainstem can cause a coma. 4....

After trauma, a Glasgow Coma Scale score of 3 to 5 may indicate fatal brain damage, especially if pupils are fixed or oculovestibular reflexes are absent. After cardiac arrest , clinicians must exclude major confounders of coma, including sedatives, neuromuscular blockade, hypothermia, metabolic derangements, and severe liver or kidney failure.
There are three levels of brain injury, classified based on severity. These levels include: Mild. Moderate. Severe. Doctors use a special scale called the Glasgow Coma Scale to determine the severity and level of brain injury a patient suffers. This scale requires doctors to evaluate the patient’s response to certain stimuli.
