What is the difference between thrombotic and embolic
Quivers cause the blood to pool, forming clots that can travel to the brain and cause a stroke. Cerebral or intracerebral hemorrhage is caused by a cerebral aneurysm, which is the ballooning out of a weak spot in a blood vessel of the brain. When the aneurysm bursts, there is bleeding into the brain. The amount of bleeding and the location in the brain determine how severe the cerebral hemorrhage is.
In many cases, people with cerebral hemorrhages die from increased pressure on their brains. But people who survive a cerebral hemorrhage tend to recover more fully and have fewer disabilities than those who have had strokes caused by a blockage ischemic strokes. Ischemic strokes are more devastating because part of the brain dies when a blood vessel is blocked, and the brain cannot make new cells to replace the cells that have died.
But with a cerebral hemorrhage, the stroke is caused by the pressure of the blood pushing against part of the brain. If the person survives a cerebral hemorrhage, the pressure slowly goes away, and the brain may get back some of its former function.
A subarachnoid hemorrhage happens when a blood vessel on the surface of the brain bursts. Please turn on JavaScript and try again. Main Content. Important Phone Numbers. Top of the page.

In addition, pressure builds up in surrounding tissues and irritation and swelling occur, which can lead to further brain damage. Hemorrhagic strokes are divided into 2 main categories, including the following:. Subarachnoid hemorrhage. Bleeding is in the subarachnoid space the space between the brain and the membranes that cover the brain.
Intracerebral hemorrhage is usually caused by high blood pressure. Bleeding occurs suddenly and rapidly. There are usually no warning signs and bleeding can be severe enough to cause coma or death. Subarachnoid hemorrhage results when bleeding occurs between the brain and the membrane that covers the brain meninges in the subarachnoid space. This type of hemorrhage is often due to an aneurysm or an arteriovenous malformation AVM. It can also be caused by trauma. An aneurysm is a weakened, ballooned area on an artery wall and has a risk for rupturing.
Aneurysms may be congenital present at birth , or may develop later in life due to such factors as high blood pressure or atherosclerosis. An AVM is a congenital disorder that consists of a disorderly tangled web of arteries and veins. The cause of AVM is unknown, but it is sometimes genetic or part of certain syndromes. Recurrent strokes occur in about 1 in 4 people who have had a stroke within 5 years after a first stroke. The risk is greatest right after a stroke and decreases over time.
The likelihood of severe disability and death increases with each recurrent stroke. At 88 years old, Mary is an avid Scrabble player and church choir singer. She knows her way around the iPad.
