Causes of Brain Hemorrhage


Brain Hemorrhage - A General Overview

Brain hemorrhage is a kind of severe stroke that can kill a person or paralyze him for the rest of his life, if he is not subjected to proper treatment in time. Though serious, brain hemorrhage is preventable, and to prevent it you need to be aware of its causes and symptoms.

Brain hemorrhage is a type of stroke wherein damage induced to the artery results in localized bleeding in the brain, and destroys the tissues and cells in the vicinity. When the rupture caused to the wall of the blood vessels results in blood spill, the blood enters the area wherein vital tissues and cells of brain are located and kills them. It is a severe condition, wherein the person needs immediate medication/treatment - if the person is not subjected to proper treatment in time, it can result in further complications like loss of brain function and cause coma or death.

What are the Causes of Brain Hemorrhage?

Right from high blood pressure to brain tumor - any condition which causes the blood vessels to weaken can make you vulnerable to brain hemorrhage. In fact, 80 percent of the brain hemorrhage patients are known to have a history of high blood pressure. Other common conditions which contribute to weakening of blood vessels include head trauma (common in people under 50), aneurysm (which results in swelling of blood vessel walls thus making them vulnerable to bursting), blood vessel abnormalities (like amyloid angiopathy in aged people), bleeding disorders such as hemophilia and anemia, formation of some substances in the blood vessels which are carried along with blood to the brain, brain functional malformation, etc.

In fact, you are at a high risk of suffering from brain hemorrhage, if
  • You are constantly under pressure/stress in your personal or professional life.
  • You have a family history of brain hemorrhage.
  • You have weak blood vessels due to some underlying condition.
  • You have a mutation in cystatin C gene.
  • You suffer from chronic high blood pressure.
  • You drink or smoke (or resort to substance abuse) very often.
What are the Symptoms of Brain Hemorrhage?

Even though brain hemorrhage occurs in a flash without any warning in most of the cases, some symptoms are considered to be the warning bells for impending disaster. You should look out for these hemorrhage symptoms to figure out if you are vulnerable to it. A sudden and very intense headache, vomiting/nausea are most common brain hemorrhage symptoms. If you experience that your body parts are not responding to your will, i.e., if you feel paralyzed or in other words if you feel sudden numbness in body organs (this may be a momentary condition), then you should consult your physician for further diagnosis. In case of pinprick hemorrhages in the brain, the leakage of blood starts very slowly and very small quantity of blood spills out of the vessel in the sensitive area of the brain. In such cases, the patient does not get a severe stroke, but he slowly starts losing his consciousness.

Diagnosis and Treatment

There are series of tests that are used to diagnose a condition which is likely to lead to brain hemorrhage. A CT (Computerized Tomography) scan or MRI (Magnetic Resonance Imaging) scan can help find out where the hemorrhage has occurred. Lumbar puncture - i.e. surgical removal of fluid from the subarachnoid space of the lumbar region of the spinal cord for diagnostic purpose, angiography - imaging done by injecting a radio-opaque contrast agent into the blood vessel, etc., are other tests that are used in the diagnosis of brain hemorrhage.

The treatment of brain hemorrhage depends on its location and severity, so does the success of any surgery. Diagnostic radiology, interventional radiology and microsurgical techniques are a few treatment options available for brain hemorrhage. The doctor will select the best option depending on the type of brain hemorrhage. In most cases, surgery is employed in order to remove the spilled blood, and is followed by a stitch to the artery to stop the blood leakage. Treating brain hemorrhage by surgery has its own pros and cons. While the patient can successfully come out of the deadly situation, in some cases he may end up losing his life. At times, the patient may even have to sacrifice the functionality of the affected organ as a consequence of brain hemorrhage stroke.

As brain hemorrhage causes severe stroke in patients, recovery of the patient carries many possibilities - some patients resume their normal life after treatment (which can be a long-term or short-term treatment depending upon therapy used), while some end up losing the functionality of the organ which was affected by the stroke. It is very difficult to predict how much time recovery from brain hemorrhage will take as it is bound to differ from case to case.

Though the fact that brain hemorrhage can be fatal is quite alarming, the better part is that it can be prevented by identifying risk factors and working on them. Chronic blood pressure, for instance, is the biggest culprit when it comes to hemorrhage causes - which means treatment of hypertension can help you reduce the risk of suffering from brain hemorrhage. Same rule applies to other risk factors - such as head trauma, which can be prevented by taking necessary precautions like wearing helmet while riding a bike. With the consequences of brain hemorrhage being so severe, it is wise to go by the age-old adage - prevention is better than cure.
