A brain hemorrhage can be the result of a burst artery in the brain, and risk factors for this include head trauma, amyloid angiopathy, high blood pressure or an aneurysm. Other risk factors include blood vessel abnormalities, liver disease, blood disorders and brain tumors, according to WebMD.
A head injury is the most common cause of a brain hemorrhage in patients under the age of 50. Amyloid angiopathy is an abnormality in the blood vessel walls that happens with age and instances of high blood pressure, reports WebMD. High blood pressure is a chronic condition that may weaken blood vessel walls over time. This is a preventable cause, but if it goes untreated, it may lead to a brain hemorrhage.
An aneurysm is a swelling that occurs in weakened blood vessel walls. Aneurysms may burst, causing bleeding in the brain which may then cause a stroke. Brain hemorrhages themselves are classified as a type of stroke, notes WebMD.
The medical term for blood vessel abnormalities is "arteriovenous malformations," and they are sometimes present at birth. Doctors diagnose these abnormalities only if symptoms develop, explains WebMD. Liver disease is a condition commonly associated with increased bleeding. Hemophilia and sickle cell anemia are two examples of blood disorders also associated with brain hemorrhages.
