Intracerebral hemorrhage (ICH) is when blood suddenly bursts into brain tissue, causing damage to the brain.
Symptoms usually appear suddenly during ICH. They include headache, weakness, confusion, and paralysis, particularly on one side of the body. The buildup of blood puts pressure on the brain and interferes with its oxygen supply. This can quickly cause brain and nerve damage.
This is a medical emergency requiring immediate treatment. ICH is not as common as ischemic stroke (when a blood vessel is blocked by a clot), but it’s more serious.
Treatment generally involves surgery to relieve the pressure from the accumulation of blood and to repair damaged blood vessels. Long-term treatment depends on the hemorrhage location and the amount of damage. Treatment may include physical, speech, and occupational therapy. Most people have some level of permanent disability.
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:
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.
Symptoms of ICH include:
This is a serious medical condition. If you or someone near you is having symptoms of stroke, call paramedic immediately.
If you have some symptoms of ICH, a doctor will perform a neurological exam. Imaging tests determine if you’re having an ischemic stroke (blockage) or a hemorrhagic stroke (bleeding).
Diagnostic testing for ICH may include a CT scan. This type of test creates images of the brain, which can detect skull fractures or confirm bleeding. MRI may help your doctor see the brain more clearly to better identify the cause of the bleeding. An angiogram uses X-ray technology to take pictures of blood flow within an artery. Blood tests can identify immune system disorders, inflammation, and blood clotting problems that can cause bleeding in the brain.
Depending on the location of the hemorrhage and how long your brain was without oxygen, complications may include:
Treatment within the first three hours of the onset of symptoms generally results in a better outcome.
Surgery can relieve pressure on the brain and repair torn arteries. Certain medications can help manage symptoms, such as painkillers to ease severe headaches. Antianxiety drugs may be necessary to control blood pressure. If your doctor determines that you’re at risk for seizures, antiepileptic drugs may be necessary.
Long-term treatment will be needed to overcome symptoms caused by damage to the brain. Depending on your symptoms, treatment may include physical and speech therapy to help restore muscle function or improve communication. Occupational therapy may help a person regain certain skills and independence by practicing and modifying everyday activities.
You can decrease your chances of ICH by:
Recovery following ICH differs greatly from person to person, and will depend on a variety of factors, including your age and overall health, the location of the hemorrhage, and the extent of the damage.
Some people may take months or years to recover. Most ICH patients have some long-term disability. In some cases, around the clock or nursing home care may be necessary.
