Stroke is caused by a decrease in oxygen supply to a particular region of the brain due to blockage of blood circulation, which can occur by formation and a clot (ischemic stroke) or by a hemorrhage in the brain (hemorrhagic stroke).
Hemorrhagic stroke occurs when a weakened blood vessel ruptures in the brain, causing bleeding at the site and leading to blood accumulation and consequent increased pressure in the region, preventing blood from circulating efficiently to surrounding areas. Decreased oxygen supply can lead to the death of brain cells in this region, which can lead to serious and permanent injuries.
Thus, in the face of an episode of stroke, it is important to ask for medical help as soon as possible in order to avoid permanent sequelae.
How to identify symptoms
Some of the symptoms that may occur during an episode of hemorrhagic stroke are:
- Severe headache;
- Nausea and vomiting;
- Difficulty speaking or swallowing;
- COnfusion and disorientation;
- Weakness or tingling in the face, arm or leg of only one side of the body;
- Loss of consciousness;
- Dizziness or loss of balance;
The most common causes of hemorrhagic stroke are very high pressure, which can lead to rupture of a blood vessel, head trauma due to falls or accidents, aneurysms or other malformations of blood vessels of the brain, which have a higher risk of dofrer rupture or hemorrhage, especially when its size increases over time, or incorrect use of anticoagulants or antiplatelet agents , which may increase the risk of bleeding.
In addition, although it is rarer, hemorrhagic stroke can also be caused by diseases that hinder blood clotting, such as hemophilia and thrombocythemia, inflammations of the small brain vessels, degenerative diseases of the brain such as Alzheimer’s, use of illicit drugs such as cocaine and amphetamine, and brain tumor, which increases the risk of bleeding.
Differences between ischemic stroke and hemorrhagic stroke
While hemorrhagic stroke is caused by the rupture of a vessel in the brain, decreasing the intake of blood to the cells, ischemic stroke arises when a clot clogs a brain vessel, disrupting blood circulation, preventing oxygen from reaching the cells.
Although they occur differently, both types of stroke cause similar symptoms.
What is the diagnosis
The diagnosis of a hemorrhagic stroke is made by assessing symptoms and performing a CT scan, which allows to visualize cerebral hemorrhage. In addition, this diagnostic means is useful for detecting arteriovenous malformations, aneurysms and tumors, which are factors of laughter for the occurrence of stroke.
How treatment is done
Treatment should be done as soon as possible in order to avoid permanent sequelae, which initially consists of controlling bleeding and relieving pressure in the brain and also administration of diuretic remedies.
If bleeding is controlled with the initial relief measures, the person only needs to be monitored and later to do physiotherapy sessions. However, if bleeding is uncontrolled, surgery may need to be used to repair the blood vessel and stop the bleeding
How to prevent
Some measures can be taken to prevent the occurrence of stroke, such as controlling blood pressure in order to avoid spikes, avoiding alcohol, cigarette and drug consumption, and making rational use of medications, especially anticoagulants that, if taken incorrectly, may increase the risk of developing a stroke.
