What can be done to prevent the condition?

The best prevention is to manage high blood pressure. Lower blood pressure puts less stress on a damaged blood vessel wall. Treating clotting problems can reduce the risk of bleeding from aneurysms. A person with a diagnosed aneurysm should not take medicines that thin the blood.

What are the long-term effects of the condition?

The blood from a ruptured aneurysm dissolves and gets absorbed within a few days. Sometimes the breakdown of red blood cells produces excess protein. The excess protein draws fluid into the space around the brain. Repeated spinal taps can be done to remove excess protein and prevent fluid buildup. In some cases, a ventriculoperitoneal shunt is inserted in the brain. This tube carries the excess fluid from the brain down into the abdominal cavity.

What are the risks to others?

A cerebral aneurysm poses no risk to others.
