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.
In the previous two articles, we have discussed patients with intractable epilepsy who have benefited from epilepsy surgery to remove or disconnect the area of the brain that propagates their seizures. Another group of people who may benefit from epilepsy surgery is those who have generalized seizures - seizures where there is no clear onset in the brain. These children may also have severe developmental delays, worsened by years of seizures. These children are the ones who can benefit from corpus...
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.
