Mortality rates for intracranial hemorrhage, or bleeding in the brain, is near 50 percent during the first 30 days, states Columbia University. Intracranial hemorrhage is positively correlated with traumatic brain injury, though not all TBI suffers will experience bleeding in the brain.
Intracranial hemorrhage is one of the most deadly types of strokes, explains a Buffalo University article. More than one-third of victims pass away, with three-quarters of survivors still exhibiting severe disability more than a year after the initial trauma. Bleeding in the brain occurs when a hematoma, or tumurous collection of blood, bursts from a blood vessel and begins leaking blood into either the brain itself or the membranous layer surrounding the brain, states brainline.org. Both types of bleeding creates pressure within the skull, which damages essential brain structures.
