There are two types: The most common cause is high blood pressure hypertension. There are 3 layers of membrane or meninges that cover the brain. A subarachnoid haemorrhage is a bleed that happens between the layer closest to the brain and the second layer.

Causes of haemorrhagic stroke Haemorrhagic stroke can be caused by a number of disorders which affect the blood vessels, including long-standing high blood pressure and cerebral aneurysms.

Aneurysm This is a weak or thin spot in the wall of an artery that balloons out. As the aneurysm gets bigger, it gets weaker and can burst. If the aneurysm bursts, it leaks blood into the brain. The weak spots that cause aneurysms are usually present at birth.

A burst aneurysm is usually caused by high blood pressure hypertension or trauma a sudden injury to the head. It can occur anywhere in the body, including the brain.

An AVM is usually present at birth. It may be that as you get older the blood vessels get bigger and weaker.
