Symptoms of Bleeding Brain
Why Herrmohage Damage The Brain
Subarachnoid bleeding brain or hemorrhage, or bleeding between the first two layers of tissue that protect the brain, is the subject of two papers published in January by Columbia Health Sciences researchers. One study examined predictors of cognitive dysfunction after such a bleeding brain and the other looked at whether an inflammatory marker can predict quality of life after the initial injury. By understanding what leads to impairment, doctors hope to develop interventions to prevent damage.
The publications employ data from a study on subarachnoid bleeding brain patients that Dr. Stephan Mayer, associate professor of clinical neurology (in neurological surgery) at P&S, and Kurt Kreiter, a doctoral student in neurology at P&S, began approximately five years ago. Dr. E. Sander Connolly, associate professor of neurological surgery, and his group later joined the study, which has about 500 patients enrolled.
A subarachnoid bleeding brain usually is caused by a ruptured aneurysm. Aneurysmal subarachnoid bleeding brain affects nearly 30,000 people in North America each year. The mortality rate in the first 30 days after the hemorrhage is about 50 percent, which is the highest for any type of stroke. Approximately half the survivors end up permanently disabled because of cognitive problems. While aneurysms can happen in any place in the circulatory system, these blood vessel dilations or balloonings typically occur in brain and heart arteries. In a subarachnoid bleeding brain, the aneurysm bursts and blood spills into the subarachnoid space around the brain, where the blood mixes with cerebrospinal fluid.
Spasm of the blood vessels—where the muscles that line the blood vessel wall contract and clamp down on the artery—and more bleeding from the original aneurysm can lead to death and stroke for a cerebral bleeding brain patient. If the bleeding vessel is surgically accessible, a clip can be put around the aneurysm or coils can be placed inside the aneurysm to speed clotting and close off the cavity. New York-Presbyterian Hospital has a neuro-intensive care unit that treats bleeding brain patients with surgery and other methods. But not much can be done to treat vasospasm.
The cognitive dysfunction study, led by Dr. Mayer, evaluated 113 patients three months after their bleeding brain and quantified the problems associated with subarachnoid bleeding brain, including location of the blood, hydrocephalus, edema (swelling), strokes, and infarction, or neural tissue death due to lack of blood. The research team found swelling and small strokes were the most important factors related to how badly the brain is affected. These findings were surprising to Dr. Mayer and his team because other published research had not investigated the effect of swelling on cognitive outcomes.
While it may be too soon to employ specific treatments from the findings, reducing swelling and removing leaked blood could limit harm. Strategies to reduce infarction, particularly on the brain’s left side where much of our verbal abilities are housed, are also needed, Mr. Kreiter says.
Dr. Mayer’s laboratory is continuing to study subarachnoid bleeding brain and improving questionnaires, rating scales, and operational definitions in the neuropsychological tests patients take. The revised tests should more easily identify levels of impairment, enabling research and treatment to focus on the deficit areas.
The other study, led by Dr. Connolly, looked at levels of one inflammation marker, intercellular adhesion molecule-1, or ICAM-1, in serum after hemorrhage. Based on assessments of 101 patients, the researchers concluded that ICAM-1 was elevated in subarachnoid bleeding brain and that these higher levels of the marker in the bloodstream were associated with poor quality of life for patients. The investigators checked ICAM-1 levels every other day for 12 days after the initial hemorrhage. The study appeared in the January issue of the Journal of Neurosurgery.
One reason the researchers chose ICAM-1 is that animal models of subarachnoid bleeding brain have shown that blocking ICAM-1 improved outcome. However, blocking ICAM-1 in human trials has not worked. A study done elsewhere that used an ICAM-1 antibody to treat stroke patients had to be halted because treated patients had adverse reactions to the antibody.

Symptoms of Bleeding Brain
What causes bleeding in the brain?
There are several risk factors and causes of bleeding brain or hemorrhages. The most common include:
* Head trauma. Injury is the most common cause of bleeding in the brain for those under 50.
* High blood pressure. This chronic condition can, over a long period of time, weaken blood vessel walls. Untreated high blood pressure is a major preventable cause of brain hemorrhages.
* Aneurysm. This is a weakening in a blood vessel wall that swells. It can burst and bleed into the brain, leading to a stroke.
* Blood vessel abnormalities. Weaknesses in the blood vessels in and around the brain may be present at birth and diagnosed only if symptoms develop.
* Amyloid angiopathy. This is an abnormality of the blood vessel walls that sometimes occurs with aging. It may cause many small, unnoticed bleeds before causing a large one.
* Blood or bleeding disorders. Hemophilia and sickle cell anemia can both contribute to decreased levels of blood platelets.
* Liver disease. This condition is associated with increased bleeding in general.
* Brain tumors.

What are the symptoms of brain bleeding?
What are the symptoms of brain bleeding?
The symptoms of a brain hemorrhage can vary. They depend on the location of the bleeding, the severity of the bleeding, and the amount of tissue affected. Symptoms may develop suddenly or over time. They may progressively worsen or suddenly appear.
If you exhibit any of the following symptoms, you may have a brain hemorrhage. This is a life-threatening condition, and you should call 911 or go to an emergency room immediately. The symptoms include:
* a sudden severe headache
* seizures with no previous history of seizures
* weakness in an arm or leg
* nausea or vomiting
* decreased alertness; lethargy
* changes in vision
* tingling or numbness
* difficulty speaking or understanding speech
* difficulty swallowing
* difficulty writing or reading
* loss of fine motor skills, such as hand tremors
* loss of coordination
* loss of balance
* an abnormal sense of taste
* loss of consciousness
Keep in mind that many symptoms of bleeding brain are often caused by conditions other than brain hemorrhages.

Brain Bleeds Common in Babies
Brain Bleeds Common in Babies
Brain bleeds are common in babies who are born vaginally, but the bleeding is limited and appears to have no effect, according to a report published in Radiology.
Bleeding in or around the brain can occur in any newborn but is particularly common in those born prematurely; about 20% of premature infants have bleeding in the brain. In some cases, symptoms of bleeding brain such as brief pauses in breathing, slow heart rate, and seizures. Typically small bleeds resolve over time without causing problems, but more serious cases may result in seizures, learning disabilities, or problems with motor development.
In this study, 88 newborn babies who showed no symptoms of bleeding were assessed using MRI between the ages of one and five weeks. Sixty-five of the babies were delivered vaginally and the rest by caesarian section.
They found that one in four babies had at least one type of brain bleed and a small percent had bleeding in two or more areas of the brain. None of the babies with bleeding had been delivered by caesarian section. The bleeding was associated with vaginal birth but not with the duration of labour or with the methods of delivery.
The experts say that small bleeds in and around the brain are very common in babies who are born vaginally, and it is likely that our brains have evolved to cope with vaginal births without too much difficulty.
Since the MRI was not taken immediately after birth, they say that some cases may have been missed and that the incidence of brain bleeds following birth may in fact be much greater.
Further studies are needed to assess whether symptoms of bleeding brain are associated with later developmental problems, such as epilepsy.

Brain Aneurysm
Brain Aneurysm
A brain aneurysm is a weakness in the wall of an artery causing a pouch or a swelling in the blood vessel. The thin walls of an aneurysm can burst and cause bleeding into the tissues of the brain.
Symptoms of Bleeding Brain / aneurysm
There usually are few symptoms of bleeding brain or aneurysm. Sometimes, brain aneurysms press on a nerve or leak small amounts of blood before a major rupture, thus producing warning signs. These symptoms, which can occur minutes to weeks before a rupture, include:
* Severe headache
* Facial pain
* Double vision, droopy eyelid or other vision problems
If you have these symptoms, you should see a doctor quickly so that steps can be taken to prevent a massive hemorrhage or bleeding brain.
An actual rupture can produce the following symptoms:
* A sudden, severe headache
* A brief loss of consciousness that often follows the onset of the headache. Some people remain in a coma, but most often patients wake up feeling confusedand sleepy. Within a few minutes or few hours, the patient may again begin to feel confused and sleepy.
* Vomiting
* Dizziness
* Frequent fluctuations in the heartbeat and breathing rate often occur
* Seizures
* Paralysis on one side of the body or neurologic problems (usually occuring in about 25% of the people who have subarachnoid hemorrhages)
Diagnosis
Because brain aneurysms are silent until they cause bleeding of the brain, a timely diagnosis can be difficult. The diagnosis of a subarachnoid hemorrhage can usually be made with a computed tomography (CT) scan. If the CT scan is not conclusive, a lumbar puncture (spinal tap) can be done to confirm or rule out the diagnosis.
Approximately one-third of those who have a subarachnoid hemorrhage or symptoms of bleeding brain die during the hemorrhage because of extensive brain damage. Without
proper treatment for the brain aneurysm, 20 to 30% will have a second bleed within the first month and those who survive three months have approximately a 3% chance every year of having another episode of bleeding. Recurrent bleeding has a 70% mortality rate.
Because of the ominous prognosis with delayed definitive therapy, referral to a center of excellence with experience in treating subarachnoid hemorrhage is imperative.
Treatment for Bleeding Brain Symptoms
Symptoms of bleeding brain require emergency evaluation and treatment. If a subarachnoid hemorrhage is confirmed and the patient is medically and neurologically stable, members of the stroke team will confer about the timing and choice of the best diagnostic and treatment options. Usually, magnetic resonance angiography (MRA), CT angiography (CTA) and/or contrast angiography are used to determine the exact size and location of the brain
aneurysm. Depending on the results, an interventional radiology, neurosurgical or combination approach is chosen. It is critical to have doctors with the experience, judgment and technical know-how to make the right choices for each patient.

Bleeding in the brain
Bleeding in the brain
Bleeding in the brain: A condition which is characterized by the abnormal loss of blood from blood vessels located in the brain.
A brain bleeding / hemorrhage is a type of stroke. It’s caused by an artery in the brain bursting and causing localized bleeding in the surrounding tissues. This bleeding kills brain cells.
The Greek root for blood is hemo. Hemorrhage literally means “blood bursting forth.”Brain hemorrhages are also called cerebral hemorrhages, intracranial hemorrhages, or intracerebral hemorrhages.
They account for about 13% of strokes. Oscar-winning director of The English Patient Anthony Minghella, President Franklin D. Roosevelt, and actor Richard Burton all died of brain hemorrhages.
What happens during a brain hemorrhage?
When blood from a traumairritates brain tissues, it causes swelling. This is known as cerebral edema. The pooled blood collects into a mass called a hematoma. These conditions increase pressure on nearby brain tissue, and that reduces vital blood flow and kills brain cells.
Bleeding can occur inside the brain, between the brain and the membranes that cover it, between the layers of the brain’s covering or between the skull and the covering of the brain.
What are the symptoms of bleeding brain?
There are several risk factors and causes of brain hemorrhages. The most common include:
* Head trauma. Injury is the most common cause of bleeding in the brain for those under 50.
* High blood pressure. This chronic condition can, over a long period of time, weaken blood vessel walls. Untreated high blood pressure is a major preventable cause of brain hemorrhages.

Symptoms of Bleeding Brain
Symptoms of Bleeding Brain
As a diabetic one of the things I must watch out for is strokes or aneurysms, etc. When diabetes is not controlled it can wreak havoc on the small blood vessels in our organs. This can over time cause those blood vessels to hemorrhage and this can manifest itself in a variety of ways. It can cause a stroke which is in when the blood stops flowing through a blood vessel and ceases to provide blood to a part of the brain, thus causing that part of the brain to die, subsequently we loose the functionality that part of the brain controlled. The opposite end of the spectrum is what is called an aneurysm, which is the rupture of a blood vessel. This causes bleeding of the brain and if not addressed quickly can lead to death. So it is important that we know the symptoms of bleeding brain. They are:
If the blood vessel has ruptured:
* Nausea and vomiting
* Stiff neck or neck pain
* Blurred vision or double vision
* Pain above and behind the eye
* Dilated pupils
* Sensitivity to light
* Loss of sensation
If the blood vessel has not ruptured:
* Peripheral vision deficits
* Thinking or processing problems
* Speech complications
* Perceptual problems
* Sudden changes in behavior
* Loss of balance and coordination
* Decreased concentration
* Short-term memory difficulty
* Fatigue
Noticing these symptoms of bleeding brain for anyone would be wise, but especially so for diabetics. Early, proactive action will save your life.
