Some examples are: 1  Traumatic brain injuries. Traumatic brain injuries, often caused by traffic collisions or acts of violence, are common causes of comas. 2  Stroke. Reduced or interrupted blood supply to the brain (stroke), which may be caused by blocked arteries or a burst blood vessel, can result in a coma. 3  Tumors.
Coma Overview. A coma is a deep state of unconsciousness in which individuals do not consciously respond to stimuli in their environment. Coma can result from injury such as head trauma, or an underlying illness such as an infection or tumor, or toxins that enter the body. Patients in a coma are unable to think consciously and lack awareness of their surroundings, but they do retain basic life support functions, such as breathing and circulation.
