Simply explained, a brain contusion is a bruise of the brain tissue. Just like bruises that occur on other parts of the body, a brain contusion is caused by small blood vessel leaks. Because they involve structural brain damage, contusions are more serious than concussions.
Bruises are caused by an injury or blow to a specific body part that breaks blood vessels underneath the skin. Blood seeps out of the vessels causing discoloration, swelling, and pain. Bruises can also be caused by nutrient deficiencies, insufficient blood clotting factors, and serious illnesses like leukemia.
