Most subarachnoid hemorrhages are caused by a ruptured brain aneurysm. A brain aneurysm is a bulge in a blood vessel caused by a weakness in the blood vessel wall.

is not known exactly why cerebral aneurysms develop in some people. However, certain risk factors have been identified, including:

• smoking
• high blood pressure
• excessive alcohol consumption

less common causes of subarachnoid hemorrhage include having an abnormal development of blood vessels and inflammation of blood vessels in the brain.

serious head injuries often cause subarachnoid hemorrhage, but this is a separate problem known as "traumatic subarachnoid hemorrhage".

Who is affected?

Between April 2013 and April 2014, more than 6,000 people were admitted to hospitals in England with a subarachnoid hemorrhage.

subarachnoid hemorrhages can occur at any age but are most common in people aged between 45 and 70. Slightly more women are affected than men.
