What Happens During a Brain Hemorrhage?
When blood from a 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 under 50. • High blood pressure. This chronic condition can, over a long period of time, weaken blood vessel walls. Untreated high blood pressure is a major preventable cause of brain hemorrhages. • Aneurysm. This is a weakening in a blood vessel wall that swells. It can burst and bleed into the brain, leading to a stroke. • Blood ve
