What Happens During a Brain Hemorrhage?
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.
- 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 vessel abnormalities. (Arteriovenous malformations) Weaknesses in the blood vessels in and around the brain may be present at birth and diagnosed only if symptoms develop.
- Amyloid angiopathy. This is an abnormality of the blood vessel walls that sometimes occurs with aging and high blood pressure. It may cause many small, unnoticed bleeds before causing a large one.
- Blood or bleeding disorders. Hemophilia and sickle cell anemia can both contribute to decreased levels of blood platelets.
- Liver disease. This condition is associated with increased bleeding in general.
- Brain tumors.
What Are the Symptoms of Brain Bleeding?
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.
If you exhibit any of the following symptoms, you may have a brain hemorrhage. This is a life-threatening condition, and you should call 911 or go to an emergency room immediately. The symptoms include:
- A sudden severe headache
- Seizures with no previous history of seizures
- Weakness in an arm or leg
- Nausea or vomiting
- Decreased alertness; lethargy
- Changes in vision
- Tingling or numbness
- Difficulty speaking or understanding speech
- Difficulty swallowing
- Difficulty writing or reading
- Loss of fine motor skills, such as hand tremors
- Loss of coordination
- Loss of balance
- An abnormal sense of taste
- Loss of consciousness
Keep in mind that many of these symptoms are often caused by conditions other than brain hemorrhages.

It is bleeding inside the skull. Here is what WIKIPEDIA says, and I urge you to check the website, WIKIPEDIA, for a lot more information, including causes, prognosis, etc.
A cerebral haemorrhage (also spelled hemorrhage) (aka intracranial hemorrhage, cerebral hematoma, intracranial hematoma) is a subtype of intracranial hemorrhage that occurs within the brain tissue itself. It is alternatively called intracerebral hemorrhage (ICH). It can be caused by brain trauma, or it can occur spontaneously in hemorrhagic stroke. Non-traumatic intracerebral hemorrhage is a spontaneous bleeding into the brain tissue.[1]
A cerebral hemorrhage is an intra-axial hemorrhage; that is, it occurs within the brain tissue rather than outside of it. The other category of intracranial hemorrhage is extra-axial hemorrhage, such as epidural, subdural, and subarachnoid hematomas, which all occur within the skull but outside of the brain tissue. There are two main kinds of intra-axial hemorrhages: intraparenchymal hemorrhage and intraventricular hemorrhages. As with other types of hemorrhages within the skull, intraparenchymal bleeds are a serious medical emergency because they can increase intracranial pressure, which if left untreated can lead to coma and death. Themortality rate for intraparenchymal bleeds is over 40%.[2]
