Brain Aneurysm

By Anastacia Bernal

Symptoms

A sever headache is the key symtopm of a ruptured aneurysm. This headache iss often as the ‘worst headache’ ever experienced. Common signs and symptoms of a ruptured aneurysm include-

•Severe headache

•Nausea and vomiting

•Stiff neck

•Blurred or double vision

•Sensitivity to light

•Seizure

•A drooping eyelid

•Loss of concousness

•Confusion


This disorder takes affect to the brain


Causes

Brain Aneurysm is an abnormal widening to an artery or vein in the brain. A brain aneurysms are caused by a weakness in the wall of an artery or vein within the brain. Brain aneurysms may result from a malformation (birth defect) of a blood vessel, high blood pressure which damages the blood vessel, arteriosclerosis (built-up of fatty deposits in the arteries), or head trauma.


Who has a better risk?

Brain aneurysms can occur at any age. Although they are more common in adults, they do occur in children.


Who is affected?

An estimate of 6 million people in the united states have an unruptured brain aneurysm, or 1 in 50 people. The annual rate or ruptured is approximately 8-10 per 100,000 people or about 30,000 people in the United States suffer a brain aneurysm ruptured. The is a brain aneurysm rupturing every 18 minutes. Rupturing brain aneurysms are fatal in about 40% of cases. Of those who survive, about 66% suffer some permanent neurological deficit. Approximately 15% of patients with aneurysmal subarachnoid hemorrhage (SAH) die before reaching the hospital. Most of the deaths for SAH are due to rapid and massive brain injury from the initial bleeding which is not correctable by medical and surgical interventions. 4 out of & people are most prevalent in people ages 35-60, but can and do occur in children as well. The median age when aneurysmal hemorrhagic stroke occur is 50 years old and there are typically no warning signs. Most aneurysms develop after the age 40.


How bad can it be?

In some cases, a brain aneurysm causes no symptoms and goes unnoticed. In rare cases, the brain aneurysm ruptures, releasing blood into the skull and causing a stroke. A brain aneurysm is more of a disorder than a disease. People who have a family history of brain aneurysms are more likely to have an aneurysm than those who don't. Women are more likely to develop a brain aneurysm or to suffer a subarachnoid hemorrhage. The use of cigarettes may greatly increase the chances of a brain aneurysm rupturing. Most brain aneurysms cause no symptoms and may only be discovered during tests for another, usually unrelated, condition. In other cases, an unruptured aneurysm will cause problems by pressing on areas in the brain. When this happens, the person may suffer from severe headaches, blurred vision,chages in speech and neck pain depending on what areas of the brain are affected and how bad the aneurysm is.Symptoms of a ruptured brain aneurysm often come on suddenly.

Treatments

There are two common treatment options for a ruptured brain aneurysm. Surgical clipping is a procedure to close off an aneurysm. The neurosurgeon removes a section of your skull to access the aneurysm and locates the blood vessel that feeds the aneurysm. Then the surgeon places a tiny metal clip on the neck of the aneurysm to stop blood flow to it. Endovascular coiling is a less invasive procedure than surgical clipping. The surgeon inserts a hollow plastic tube called a catheter into an artery, usually in your groin, and threads it through your body to the aneurysm. The surgeon then uses a guide wire to push a soft platinum wire through the catheter and into the aneurysm. The wire coils up inside the aneurysm, disrupts the blood flow and causes blood to clot. This clotting essentially seals off the aneurysm from the artery. Both procedures pose risks, particularly bleeding in the brain or loss of blood flow to the brain. The endovascular coil is less invasive and may be initially safer, but it also has a higher risk of subsequent re-bleeding, and additional procedures may be necessary. Your neurosurgeon will make a recommendation based on the size of the brain aneurysm, your ability to undergo surgery and other factors.

Concluding Facts

A brain aneurysm is very dangerous. There are many symstoms but in other cases there are non. Not all the people that get a brain aneurysm are lucky enough to live through it.
