A significant number of people are affected by brain aneurysms, with approximately 1 in 50 individuals living with an unruptured one. Women are at higher risk than men. Most brain aneurysms develop after age 40, and they are most common among people between 35 and 60 years old.

The consequences of a rupture can be severe, often fatal, and survivors may suffer permanent damage.

Further information on brain aneurysms and their risks is available, including details on prevalence and outcomes.
