Hemorrhagic stroke

What is hemorrhagic stroke? A stroke occurs when the normal flow of blood to the brain is interrupted, causing it to be starved of oxygen. If this is caused by a blood vessel bursting in or around the brain, it is known as a hemorrhagic stroke. A stroke is an emergency, and medical attention must be sought immediately. About one in five strokes are hemorrhagic. An acronym, FAST, explains the telltale • Face: The face becomes weak or droopy, with the effect usually more visible on one side • Arm: One arm becomes numb or weak, and there may be difficulty raising it • Speech: Speaking becomes difficult, and the affected person’s voice becomes slurred • Time to call: If any of the above is noticed, the emergency services should be called immediately The severity of the symptoms of a hemorrhagic stroke depends on what parts of the brain are affected. There are two types of hemorrhagic stroke: • An intracerebral hemorrhage (ICH), which is when a blood vessel within the brain ruptures. The main cause of ICHs is high blood pressure. About one in 10 strokes is an ICH. • [ A A hemorrhagic stroke is most often diagnosed through a brain scan, such as a CT scan. Medical treatment in a hospital and close medical supervision is required to guarantee the best possible outcome after a hemorrhagic stroke takes place. Surgery to stop the bleeding or address complications could be necessary. Rehabilitation will very often be useful in dealing with the symptoms that may develop from a hemorrha...

The Dangers of Brain Aneurysm Aneurysms can lurk without symptoms, but screening can save lives. Click here for an infographic to learn more A brain aneurysm (AN-yoo-riz-um) — also known as a cerebral aneurysm or intracranial aneurysm — is a bulge or ballooning in a blood vessel in the brain. An aneurysm often looks like a berry hanging on a stem. Experts think brain aneurysms form and grow because blood flowing through the blood vessel puts pressure on a weak area of the vessel wall. This can increase the size of the brain aneurysm. If the brain aneurysm leaks or ruptures, it causes bleeding in the brain, known as a hemorrhagic stroke. Most often, a ruptured brain aneurysm occurs in the space between the brain and the thin tissues covering the brain. This type of hemorrhagic stroke is called a subarachnoid hemorrhage. Brain aneurysms are common. But most brain aneurysms aren't serious, especially if they're small. Most brain aneurysms don't rupture. They usually don't cause symptoms or cause health problems. In many cases, brain aneurysms are found during tests for other conditions. However, a ruptured aneurysm quickly becomes life-threatening and requires medical treatment right away. If a brain aneurysm hasn't ruptured, treatment may be appropriate in some cases. Treatment of an unruptured brain aneurysm may prevent a rupture in the future. Talk with your health care provider to make sure you understand the best options for your specific needs. Types Saccular and fusifo...

Ischemic and hemorrhagic strokes occur when there is limited blood flow to a part of the brain. When part of a person’s brain does not receive enough blood, oxygen starvation can cause the brain cells there to die. An A According to the American Stroke Association, around This article describes the similarities and differences between ischemic and hemorrhagic strokes, including their causes, symptoms, diagnosis, treatment, and prevention. Share on Pinterest Halfpoint Images/Getty Images Ischemic and hemorrhagic strokes have Ischemic stroke A blockage or clot in a blood vessel that leads to part of the brain There are two types of ischemic stroke: • Thrombotic strokes: These occur when blood begins to clot in a blood vessel leading to a part of the brain. A person may experience a • Embolic strokes: These occur when a blood clot from another part of the body reaches a part of the brain and gets stuck in a blood vessel there.

What is a brain AVM? Normally, arteries carry blood containing oxygen from the heart to the brain, and veins carry blood with less oxygen away from the brain and back to the heart. When an arteriovenous malformation (AVM) occurs, a tangle of blood vessels in the brain bypasses normal brain tissue and directly diverts blood from the arteries to the veins. How common are brain AVMs? Brain AVMs occur in less than 1 % of the population. AVMs are more common in males than in females. Why do brain AVMs occur? Brain AVMs are usually congenital, meaning someone is born with one. But they’re usually not hereditary. People probably don’t inherit an AVM from their parents, and they probably won’t pass one on to their children. Where do brain AVMs occur? Brain AVMs can occur anywhere within the brain or on its covering. Do brain AVMs change or grow? Most AVMs don’t grow or change much, although the vessels involved may dilate (widen). What are the symptoms of a brain AVM? Symptoms may vary depending on where the AVM is located: • More than 50% of patients with an AVM have an intracranial hemorrhage. • Among AVM patients, 20% to 25% have focal or generalized seizures. • Patients may have localized pain in the head due to increased blood flow around an AVM. • 15% may have difficulty with movement, speech and vision. What causes brain AVMs to bleed? A brain AVM contains abnormal; therefore, “weakened” blood vessels that direct blood away from normal brain tissue. These abnormal and weak ...

What are the different types of stroke? Strokes can be classified into 2 main categories: • Ischemic strokes. These are strokes caused by blockage of an artery (or, in rare instances, a vein). About 87% of all strokes are ischemic. • Hemorrhagic stroke. These are strokes caused by bleeding. About 13% of all strokes are hemorrhagic. What is an ischemic stroke? An ischemic stroke occurs when a blood vessel that supplies the brain becomes blocked or "clogged" and impairs blood flow to part of the brain. The brain cells and tissues begin to die within minutes from lack of oxygen and nutrients. Ischemic strokes are further divided into 2 groups: • Thrombotic strokes. These are caused by a blood clot that develops in the blood vessels inside the brain. • Embolic strokes. These are caused by a blood clot or plaque debris that develops elsewhere in the body and then travels to one of the blood vessels in the brain through the bloodstream. Thrombotic stroke Thrombotic strokes are strokes caused by a thrombus (blood clot) that develops in the arteries supplying blood to the brain. This type of stroke is usually seen in older persons, especially those with high cholesterol and atherosclerosis (a buildup of fat and lipids inside the walls of blood vessels) or diabetes. Sometimes, symptoms of a thrombotic stroke can occur suddenly and often during sleep or in the early morning. At other times, it may occur gradually over a period of hours or even days. Thrombotic strokes may be precede...

What is a cerebral aneurysm? An aneurysm is a weak area in a blood vessel that usually enlarges. It’s often described as a “ballooning” of the blood vessel. How do aneurysms form? Are people born with an aneurysm? People usually aren’t born with aneurysms. Most develop after age 40. Aneurysms usually develop at branching points of arteries and are caused by constant pressure from blood flow. They often enlarge slowly and become weaker as they grow, just as a balloon becomes weaker as it stretches. Aneurysms may be associated with other types of blood vessel disorders, such as fibromuscular dysplasia, cerebral arteritis or arterial dissection, but these are very unusual. Some aneurysms are due to infections, drugs such as amphetamines and cocaine or direct brain trauma from an accident. How is an aneurysm diagnosed? Special imaging tests can detect a brain aneurysm. In the CTA (computed tomographic angiography), patients are placed on a table that slides into a CT scanner. A special contrast material (dye) is injected into a vein, and images are taken of the blood vessels to look for abnormalities such as an aneurysm. In the second test, called MRA (magnetic resonance angiography), patients are placed on a table that slides into a magnetic resonance scanner, and the blood vessels are imaged to detect a cerebral aneurysm. The most reliable test is called a diagnostic cerebral angiogram. In this test, the patient lies on an X-ray table. A small tube (catheter) is inserted thr...
