Types of Stroke

Stroke is a blood clot or bleed in the brain which can leave lasting damage, affecting mobility, cognition, sight or communication. The list below outlines the different types of Stroke
Did you know?

High blood pressure is the most important risk factor for stroke, contributing to about 50% of all strokes.

Types of Stroke

“Ischaemic” stroke (80% of strokes)

This happens when blood vessels are blocked by a clot or become too narrow for blood to get through to the brain.
The reduced blood flow causes brain cells in the area to die from lack of oxygen.

thrombosis

embolism

“Haemorrhagic” stroke (10% of strokes)

The blood vessel is not blocked but it bursts and blood leaks into the brain causing damage.

haemorrage

Subarachnoid haemorrhage (5% of strokes)

There is bleeding into the space around the brain (the subarachnoid space). This is usually due to a burst aneurysm (a weakness of the blood vessel wall).

TIA (transient ischaemic attack)
A mini-stroke – the effects usually pass quickly but a TIA must be taken seriously as it can be a warning sign..
