what are brain anurizums?

Answer 1

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 — such as a stroke — 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.

A stroke is a when a blood clot occurs in part of the brain.

Hi Alicia, hope this helps on what an aneurysm is: A cerebral aneurysm (also known as an intracranial or intracerebral aneurysm) is a weak or thin spot on a blood vessel in the brain that balloons out and fills with blood. The bulging aneurysm can put pressure on a nerve or surrounding brain tissue. It may also leak or rupture, spilling blood into the surrounding tissue (called a hemorhage). Some cerebral aneurysms, particularly those that are very small, do not bleed or cause other problems. Cerebral aneurysms can occur anywhere in the brain, but most are located along a loop of arteries that run between the underside of the brain and the base of the skull. Now, Most cerebral aneurysms are congenital, resulting from an inborn abnormality in an artery wall. Cerebral aneurysms are also more common in people with certain gentic diseases, such as connective tissue disorders and polycystic kidney disease, and certain circulatory disorders, such as arteriovenous malformations. Other causes include trauma or injury to the head, high blood pressure, infection, tumors, atherosclerosis (a blood vessel disease in which faats build up on the inside of the artery walls) and other diseases of the vascular system, cigarette smoking, and drug abuse. Aneurysms are classified in three cerebral types. A "saccular" aneurysm is a rounded or pouch-like sac of blood that is attached by a neck or stem to an artery or a branch of a blood vessel. Also known as a "berry aneurysm" because it resembles a berry hanging from a vine. This is the most common form of aneurysm. The second type is called lateral aneurysm which appears as a bulge on one wall of the blood vessel, while the fusiform aneurysm is formed by the widening along walls of the vessel.Aneurysm is also classified in size.

An aneurysm in the brain A.K.A cerebral or intracranial aneurysm is when one of the arteries in the brain bulge outward. They are usually discovered when they rupture causing bleeding in the brain. A ruptured aneursym can lead to stoke, brain damage and death.
