There are several risk factors and causes of brain hemorrhages. The most common include:
Head trauma- Injury is the most general reason of bleeding in the brain for those younger than age 50.
High blood pressure-This chronic situation can, over a long period of time, weaken blood vessel walls. Untreated high blood pressure is a major preventable reason 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-Weaknesses in the blood vessels in and around the brain may be present at birth and diagnosed only if indication develop.
Amyloid angiopathy- This is an irregularity of the blood vessel walls that sometimes happen with aging and high blood pressure. It may reason many small, unnoticed bleeds before causing a large one.
Blood or bleeding disorders- Hemophilia and sickle cell anemia can both contribute to reduce levels of blood platelets.
Liver disease– This situation is associated with increased bleeding in general.
