Aneurysm in the brain Health Article

Expectations (prognosis)

The outcome varies. Patients who are in deep comas after an aneurysm rupture generally do not do as well as those with less severe symptoms.

Ruptured cerebral aneurysms are often deadly. About 25% of people die within 1 day, and another 25% die within about 3 months. Of those who survive, more than half will have some sort of permanent disability.

Complications

• Subarachnoid hemorrhage
• Stroke
• Seizures, epilepsy
• Paralysis of any part of the body
• Permanent loss of sensation of any part of the face or body
• Other neurologic deficits (such as vision changes, loss of speech ability, cognitive decline)
• Communicating hydrocephalus

Calling your health care provider

Go to the emergency room or call the local emergency number (such as 911) if sudden or severe headache occurs, particularly if you also have nausea, vomiting, seizures, or any other neurological symptoms. Also call if you have a headache that is unusual for you.

Prevention

There is no known way to prevent the formation of a cerebral aneurysm. If discovered in time, unruptured aneurysms can be treated before causing problems.

The decision to repair an unruptured cerebral aneurysm is based on the size and location of the aneurysm, and the patient's age and general health. It must be carefully considered given the risks both in operating and in watchful waiting.
