In a recently published study, a group of researchers at the Université de Genève, Switzerland state that they have found seven genetic abnormalities that increase a person’s risk of developing a brain aneurysm. The findings of this study are published in the journal Nature genetics.

A brain or cerebral aneurysm refers to a thin area in an artery in the brain that bulges out and starts putting pressure on the brain. Over time, an aneurysm may rupture, leading to haemorrhage or bleeding inside the brain.

Estimates suggest that about 3% of the people in the world are at the risk of developing a brain aneurysm and five in every 100,000 people worldwide experience a ruptured intracranial aneurysm. About 50% of the people with a ruptured aneurysm die of it (almost 15% even before reaching the hospital).

So far, the exact cause of aneurysms is not known. However, experts suggest various factors like high blood pressure, atherosclerosis and trauma to the brain can put you at risk.
