Is it possible to prevent a sudden brain aneurysm?

No: The general consensus is that 1 in 100 people have a brain aneurysm at some point in their life. There can be a higher risk in families, and anyone with a family history should consider getting checked for the presence of this disease. There is no cure or preventative treatment.

No: They gradually expand and suddenly rupture so no specific preventive strategy.

Not really: . Do way to know the presence of aneurysm before clinical presentation unless brain was imaged for some other reason, i.e. Trauma and aneurysm noted as incidental finding.Most brain aneurysms cause no symptoms until rupture.An unruptured aneurysm will cause problems by pressing on areas in the brain.Person may have severe headaches, blurred vision, changes in speech, and neck pain, depends location.
