What is a Haemorrhagic stroke – Bleed
When an artery bursts in the brain, blood leaks out into the brain or the surrounding tissue. The damage caused by the tear and the resulting blood mass presses on the surrounding brain tissue. This type of stroke is known as Haemorrhagic, and accounts for 15% of all strokes. The word haemorrhage means bleeding from ruptured blood vessels.
- This occurs when blood leaks directly into the brain tissue and is commonly caused by the effects of raised blood pressure.
Aneurysm - Is a balloon like swelling which forms in the wall of an artery. If a person is born with a faulty artery (e.g. weakness in artery wall) it will be more susceptible to bursting. This is called an Aneurysm.
Sub-arachnoid Haemorrhage - This is where bleeding that fills the space between the brain surface and one of the covering membranes.
