Haemorrhagic stroke
Haemorrhagic Stroke
Haemorrhagic stroke (pronunciation: /hɪˈmɒrədʒɪk stroʊk/) is a type of stroke that occurs when a weakened blood vessel ruptures and bleeds into the surrounding brain. The blood accumulates and compresses the surrounding brain tissue.
Etymology
The term "haemorrhagic" is derived from the Greek word "haima" meaning "blood" and "rhegnumai" meaning "to break". "Stroke" comes from the Old English "strac", meaning "blow" or "strike".
Types of Haemorrhagic Stroke
There are two types of haemorrhagic stroke: Intracerebral haemorrhage and Subarachnoid haemorrhage.
- Intracerebral haemorrhage is when an artery in the brain bursts, flooding the surrounding tissue with blood.
- Subarachnoid haemorrhage is a bleeding in the area between the brain and the thin tissues that cover it.
Symptoms
Symptoms of a haemorrhagic stroke often include sudden headache, weakness in an arm or leg, and changes in vision, speech, or balance.
Causes
Haemorrhagic stroke is caused by bleeding in the brain, which can occur as a result of hypertension, aneurysm, or arteriovenous malformation (AVM).
Treatment
Treatment for haemorrhagic stroke includes controlling the bleeding, reducing pressure in the brain, and stabilizing vital signs, especially blood pressure.
Prognosis
The prognosis for haemorrhagic stroke depends on the location and extent of bleeding, the patient's age, overall health, and medical history.
