We have all heard about strokes but what is brain hemorrhage? Is it different from a stroke? In a clinical explanation, brain hemorrhage is a type of stroke. In this type of stroke, an artery inside your brain bursts and spills blood into the surrounding tissues. This causes the brain cells to die. A brain hemorrhage usually happens when a person has very high blood pressure and the small blood vessels weaken and results in bleeding in the brain.
Brain hemorrhages are also called cerebral hemorrhages, intracranial hemorrhages, or intracerebral hemorrhages and account for 13% of strokes.
Types of brain hemorrhagic strokes
Aneurysm – When a portion of the weakened blood vessel balloon outward and bursts, it causes a hemorrhage
Arteriovenous malformation – These are abnormally formed blood vessels and rupturing of such blood vessels causes a hemorrhagic stroke.
Causes of a brain hemorrhage
There are several causes that can cause bleeding in the blood vessels of the brain and hence brain hemorrhage:
Head trauma – An accident or an injury is one of the most common causes of brain hemorrhage below 50 years.
High Blood Pressure – High BP is a chronic condition that weakens blood vessels over time and if the condition is untreated, it can lead to hemorrhagic stroke.
Abnormalities in blood vessel – Congenital abnormalities in the blood vessels of the brains may cause hemorrhage later.
Amyloid angiopathy – Due to high blood pressure and aging, an abnormality is caused in the blood vessel walls. It can cause minor bleedings before causing a large one.
Symptoms of a brain hemorrhage
Depending on the location of the bleeding and the severity of the hemorrhage, the symptoms vary. Symptoms can continue over time or appear suddenly. Visit the hospital immediately if you notice any of these symptoms:
- Sudden severe headache
- Weakness in arms and legs
- Vomiting and nausea
- Change in vision
- Difficulty in speaking/swallowing/reading and writing
- Loss of motor skills
- Loss of balance and coordination
- Loss of consciousness
However, these symptoms do not necessarily mean a brain hemorrhage.
Best possible treatment of brain hemorrhage
Based on the symptoms and imaging tests like CT scan test or MRI, your doctor might be able to determine which part of the brain is affected. The treatment to be administered depends on the location, cause and the severity of the hemorrhage.
Surgery, tablet medications or diuretic pills are given to stop the bleeding and alleviate pain.
What are the chances of brain hemorrhage survival?
There are high chances of survival from brain hemorrhage depending on the size of the hemorrhage and the amount of swelling. Some patients recover completely and live a normal life once again whereas others face complications like loss of brain function, stroke, or side effects from medications and treatment.
About 40% of cases of ruptured brain aneurysms are fatal.
