Stroke News and Research

RSS

A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.

Stroke incidence related to blood type: Study

A latest study reveals that the risk for stroke maybe tied to blood type, with men and women with type AB and women with type B facing greater risk than people with type O. Researchers add that this study does not prove the link but it agrees with other studies that have tied A, B, and AB to heart attack and to blood clots in the legs. And type O has been linked to a heightened risk for bleeding, which implies less chance of the clots that are responsible for most strokes.

Vitamin D and its good and bad effects on the heart

Vitamin D in excess may not be beneficial and may even harm the heart says a new study. Scientists have long known that low levels of the nutrient can hurt the heart, but new research shows that higher than normal levels can make it beat too fast and out of rhythm, a condition called atrial fibrillation. The study was presented at the annual meeting of the American Heart Association.

Ban smoking in cars urges BMA

The British Medical Association is calling for a ban on smoking in all cars. The BMA says research shows levels of toxins in a car after a cigarette has been smoked are up to 23 times higher than they would be in a smoky bar.

Genetic basis of human cortical regionalization similar to patterns found in other mammals, MRI study affirms

A new study using magnetic resonance imaging data of 406 adult human twins affirms the long-standing idea that the genetic basis of human cortical regionalization - the organization of the outer brain into specific functional areas - is similar to and consistent with patterns found in other mammals, indicating a common conservation mechanism in evolution.

Psoriasis may alter cholesterol composition and decrease HDL function

Collaborative research from Perelman School of Medicine at the University of Pennsylvania has shown that psoriasis patients have an increased risk of heart attack, stroke and cardiovascular death, especially if the psoriasis is moderate to severe. Now, Penn researchers have discovered the potential underlying mechanism by which the inflammatory skin disease impacts cardiovascular health.

Calcium scoring test may predict risk of heart disease

Coronary calcium in heart arteries provides important clues about risk, even among younger and elderly patients and those without traditional risk factors, according to new studies.

CIHR honors University of Calgary scientist with prestigious award for medical research

University of Calgary researcher Paul Kubes, PhD, is the recipient of one of Canada's top awards for medical research. An internationally-recognized scientist specializing in visualizing the mammalian immune system, Kubes will accept the 2011 Canada's Health Researcher of the Year award from the Canadian Institutes of Health Research (CIHR) at a ceremony in Ottawa this evening.

People with prior stroke or diabetes benefit from thrombolytic therapy

People with a history of stroke or diabetes who were given clot-busting drugs to break up blood clots after stroke fared better than those who did not receive the drugs, according to a study published in the November 16, 2011, online issue of Neurology, the medical journal of the American Academy of Neurology.

Dipyrone may reduce brain damage after stroke

An older nonsteroidal anti-inflammatory drug (NSAID) called dipyrone may offer a new approach to reducing injury to brain tissue after a stroke, according to a study in the October issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Excessive vitamin D levels can lead to onset of AF

While previous studies have linked vitamin D deficiency to an increased risk for cardiovascular disease, new research at the Intermountain Medical Center Heart Institute shows that too much vitamin D can lead to the onset of a dangerous heart condition known as atrial fibrillation.

Additional results from BioSante's LibiGel pK study on HSDD

BioSante Pharmaceuticals, Inc., today announced additional results from its principal LibiGel (testosterone gel) pharmacokinetic (pK) study. Top line data from this study were announced on September 12, 2011.

Low SBP levels within normal range may reduce risk of recurrent stroke

Among patients who experienced an ischemic stroke, systolic blood pressure levels of less than 120 mm Hg, or higher than 140 mm Hg, were associated with an increased risk of subsequent stroke, according to a study appearing in the November 16 issue of JAMA, a theme issue on cardiovascular disease. This issue is being released early online to coincide with the American Heart Association Scientific Sessions.

Geron bows out of stem cell research

Geron Corp. is removing itself from the field it pioneered – stem cell research. Late Monday, the company said it would halt its study of a stem cell-based treatment for spinal cord injury, the first embryonic stem cell trial approved in the U.S.

Atherosclerotic plaques spread downstream in coronary arteries

In human coronary arteries, atherosclerotic plaques tend to spread downstream because of the changes in blood flow patterns the plaque causes, researchers have found.

Conventional approach could soon increase recurrent stroke risk after first event

For patients who have suffered an ischemic stroke, traditional treatment prescribes keeping subsequent blood pressure levels as low as possible to reduce the risk of another stroke. A new international study, however, suggests this conventional approach may not be helpful, and could actually increase recurrent stroke risk - at least in the first few months after the first event.

Researchers discover human genes that might contribute to ALS

Amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, is a universally fatal neurodegenerative disease. Mutations in two related proteins, TDP-43 and FUS, cause some forms of ALS. Specifically, these two proteins are RNA-binding proteins that connect to RNA to regulate the translation of proteins and other cellular functions such as RNA splicing and editing. In a new study, researchers at the Perelman School of Medicine at the University of Pennsylvania discovered additional human genes with properties similar to TDP-43 and FUS that might also contribute to ALS.
