The Greek root for blood is hemo. Hemorrhage literally means "blood bursting forth." Brain hemorrhages are also called cerebral hemorrhages, intracranial hemorrhages, or intracerebral hemorrhages. They account for about 13% of strokes.
According to the Centers for Disease Control and Prevention, a traumatic brain injury (TBI) occurs when an impact to the head results in disruption of brain functioning. While post-TBI physical impairments can hinder functional independence, the behavioral, cognitive, emotional, psychosocial, and personality changes associated with TBI frequently lead to even greater problems. Comprehensive evaluation and treatment are the foundation to optimizing outcome after TBI, as the complex functions affected,...
When blood from trauma irritates brain tissues, it causes swelling. This is known as cerebral edema. The pooled blood collects into a mass called a hematoma. These conditions increase pressure on nearby brain tissue, and that reduces vital blood flow and kills brain cells.
Bleeding can occur inside the brain, between the brain and the membranes that cover it, between the layers of the brain's covering or between the skull and the covering of the brain.
What Causes Bleeding in the Brain?
There are several risk factors and causes of brain hemorrhages. The most common include:
Head trauma. Injury is the most common cause of bleeding in the brain for those younger than age 50.
The symptoms of a brain hemorrhage can vary. They depend on the location of the bleeding, the severity of the bleeding, and the amount of tissue affected. Symptoms may develop suddenly or over time. They may progressively worsen or suddenly appear.
