    What are the treatments for Cerebral Aneurysms ?
    ### Response:
    For unruptured aneurysms, treatment may be recommended for large or irregularly-shaped aneurysms or for those causing symptoms. Emergency treatment for individuals with a ruptured cerebral aneurysm may be required to restore deteriorating respiration and reduce abnormally high pressure within the brain.
