Symptoms of a brain hemorrhage
The symptoms of a cerebral hemorrhage vary according to the location and severity of the bleeding, but may include:
Paralysis on one side of the body
Difficulty walking or loss of balance
The risks of a brain hemorrhage
Strokes that are caused by a brain hemorrhage can be very dangerous, but less than one fifth of all strokes are of this type. Survivors often are left with some kind of permanent brain damage, as brain cells do not regenerate.
There are several risk factors and causes of brain hemorrhages. The most common include:
Head injuries, for people under the age of 50, this is the most common cause of bleeding inside the skull.
Abnormalities in blood vessels in and around the brain, such as an arteriovenous malformation. These may be present from birth. They are only found if symptoms develop.
Aneurysm is a weakening in a blood vessel wall that swells. It can burst and bleed into the brain leading to a stroke.
High blood pressure. High blood pressure over a long time can weaken blood vessel walls. The most common cause of hemorrhage is high blood pressure (hypertension). Since high blood pressure by itself often causes no symptoms, many people with intracranial hemorrhage are not aware that they have high blood pressure, or that it needs to be treated.
Amyloid angiopathy is an abnormality in the blood vessel walls. It occurs more often as we age. It may cause many small, unnoticed bleeds before causing a large one.
