There are two main types of stroke.

Haemorrhagic Stroke: "Burst Artery"

Haemorrhagic Stroke 

This occurs when there is a rupture of a blood vessel causing bleeding in the brain. It is usually caused by:

  • High blood pressure

  • Defects in the blood vessel wall such as cerebral aneurysms

Cerebral Aneursym 

Besides the two types of strokes mentioned above, there is also a temporary stroke known as transient ischaemic attack.  

Transient Ischaemic Attack (TIA) or "Mini-stroke"

This happens when there is a temporary interruption of blood supply to the brain. Thus there is no permanent brain damage and the symptoms go away completely within a few minutes.
