ANEURYSM CAUSES
CAUSES
Brain aneurysms develop silently. Some people may have inherited a tendency for weak blood vessels, which may lead to the development of aneurysms. Aneurysms in children are rare, and most aneurysms probably develop as a result of wear and tear on the arteries throughout a person’s lifetime. Occasionally, severe head trauma or infection may lead to the development of an aneurysm.
