Causes
High blood pressure is the most common cause of intracerebral hemorrhage. In younger people, another common cause is abnormally formed blood vessels in the brain. Other causes include:
head injury or trauma
blood clot that blocks an artery in the brain
ruptured cerebral aneurysm (weak spot in a blood vessel that bursts)
arteriovenous malformation (a grouping of malformed blood vessels in the brain that disrupts normal blood flow)
use of blood thinners
bleeding tumors
cocaine use, which can cause severe hypertension and lead to hemorrhage
bleeding disorders such as hemophilia and sickle cell anemia
Anyone can have an intracerebral hemorrhage, but your risk increases with age. According to the Mayfield Clinic, men are at higher risk than women, as are middle-aged people of Japanese or African-American descent (Mayfield Clinic, 2009).
Diagnosis
If you have some symptoms of ICH, a neurological exam will be performed. Imaging tests are used to determine if you are having an ischemic stroke (blockage) or a hemorrhagic (bleeding) stroke. Diagnostic testing for ICH may include:
Computed tomography (CT scan): This type of test creates images of the brain, which can detect skull fractures or confirm bleeding.
Magnetic resonance imaging (MRI): This type of imaging test may help your doctor see the brain more clearly to better identify the cause of the bleeding.
Angiogram: This test uses X-ray technology to take pictures of blood flow within an artery.
Blood tests may also be used to identify immune system disorders, inflammation, and blood clotting problems that can cause bleeding in the brain.
