A brain hemorrhage is a type of stroke. A brain hemorrhage is bleeding in or around the brain. It is a form of stroke. Causes of brain hemorrhage include high blood pressure (hypertension), abnormally weak or dilated (aneurysm) blood vessels that leak, drug abuse, and trauma.
High blood pressure and trauma are two leading causes. Taking blood-thinning drugs may also increase a person’s risk.
Symptoms can vary based on the location of the haemorrhage in the brain, but may include numbness or weakness in part of the face, difficulty speaking or difficulty walking.
Emergency treatment is required for cerebral haemorrhage. It usually involves medication and close monitoring in an intensive care unit. In rare cases, surgery may be required to relieve pressure around the brain.
If a blood vessel in the brain leaks or bursts and causes bleeding, a hemorrhagic stroke occurs. Compression from excessive bleeding may be so severe that oxygen rich blood is unable to flow to the brain tissue. A lack of oxygen in the brain can lead to swelling, or cerebral edema.A hemorrhage can rapidly cause brain damage and can be life-threatening. Since the brain cannot store oxygen, it relies upon a series of blood vessels to supply oxygen and nutrients. When a hemorrhage occurs, oxygen may no longer be able to reach brain tissue supplied by leaky or broken blood vessels.Complications can occur before or after medical treatment, and can include: Rebleed – until the damaged vessel is repaired, there is a risk of re-bleeding. This commonly occurs 24-48 hours after the first bleed and, if left untreated, carries an increased risk of further complications including death.
