What causes brain aneurysm and how to prevent them?

Are they pathologic or genetic related disease? Can excercise, running, vitamins or foods protect from this vascular disease or must be the micro-catheter base procedure with coils or Onyx?

From the Analyst鈥檚 resources, the high risk factors are alcohol, hypertension, hardening of the arteries, smoking, infections, deficiency of potassium and coper. A small study also says antibiotic Dyxolyne seems helping to stop the growth of abdominal aneurysm.
What are the recent discovery? Does Dyxolyne or other antibiotic therapy work?

A brain aneurysm is a ballooning-out of the wall of an artery in the brain. Often this wall is weakened by disease, injury or an abnormality present at birth. Aneurysms are often caused or made worse by high blood pressure. They aren't always life-threatening, but serious consequences 鈥?such as a stroke 鈥?can result if one bursts in the brain. This is called a hemorrhagic (or bleeding) stroke.

When a blood vessel on the brain's surface ruptures and bleeds into the space between the brain and the skull (but not into the brain itself), it's called a subarachnoid hemorrhage. When an artery in the brain bursts, flooding the surrounding tissue with blood, it's called a cerebral hemorrhage.

Several imaging techniques, such as X-ray angiography, MRI (magnetic resonance imaging) or computed tomography (CT), are used to detect aneurysms. An aneurysm may be small and not cause symptoms. A doctor will want to check it regularly to see if it's enlarging. Symptoms of an aneurysm depend on where it's located. Aneurysms in the brain can cause impaired vision and headaches. The larger an aneurysm becomes, the more likely it is to burst.

Brain aneurysms are generally treated surgically. A metal clip is secured around the base of the aneurysm. Another type of treatment involves 'packing' the aneurysm with microcoils (small, flexible wire coils). These are delivered and inserted into the aneurysm using a catheter

I think you have to be careful with your head. And be careful with cholesterol and high blood pressure stuff. Be careful with what you eat also - because we don't know what causes it,

I think there are multiple causes for them including heredity. Here's a link to tell you a lot about them.

Aneurysms can happen in other parts of the body too not just the head. They can be just as deadly in the abdomen, possibly more so because they may not give you any syptoms unless they rupture, where as in the head/brian you will have a headache (that is putting it mildly). My mom's friend had 7 that she needed operated on in the abdomen she was lucky that she had pain and had seen her doctor. She had to stop work immediately and not allow any stressors in her life. She was not allowed to drive a car. There was no given reason for them. She had not had any known relatives that suffered with them.

An aneurysm occurs at a weak point in the wall of a blood vessel (artery) that supplies blood to the brain. Because of the flaw, the artery wall bulges outward and fills with blood. This bulge is called an aneurysm. An aneurysm can rupture, spilling blood into the surrounding body tissue. A ruptured cerebral aneurysm can cause permanent brain damage, disability, or death.

There are no known methods to prevent an aneurysm from forming. If an aneurysm is discovered before it ruptures, it may be surgically removed. CT or MRI angiography may be recommended for relatives of patients with familial cerebral aneurysms.

I would think aneurysms are pathological and genetic with the chief contributor (high blood pressure) having both a pathologic and generic component.

my mom died 10 yrs ago of a aneurysm,her sister said she grabbed her head and she was gone.i dont remember her complaining of headaches, she was 53.
