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.

Comparison of the risks and benefits of fish consumption

A comparison of the risks and benefits of fish consumption suggests that government advisories warning women of childbearing age about mercury exposure should be issued with caution.

Radical prostatectomy may be a safe option for the treatment of prostate cancer

Prostate cancer is the most common non-skin cancer in American men and the third most common cause of cancer death. In patients with localized disease, radical prostatectomy is associated with lower disease-specific mortality, lower rates of local progression and metastases, and higher overall survival compared with conservative management.

Beta blockers not as effective as other drugs that reduce high blood pressure in patients with hypertension

Beta blockers are not as effective as other drugs that reduce high blood pressure in patients with hypertension, concludes a meta-analysis published online by The Lancet.

More doubt cast on benefit of beta blockers for high blood pressure

A comprehensive study has produced more evidence that a drug widely used to treat high blood pressure may not be the best option for many patients.

Brain injury can cause detrimental functional changes in brain regions far from the site of the actual injury

A study of patients who have difficulty paying attention to the left side of their environment has provided some of the first direct evidence that brain injury can cause detrimental functional changes in brain regions far from the site of the actual injury.

Discovery could lead to tests for the clinic or battlefield to diagnose ailments with just a few drops of blood

A way to detect fragments of broken brain cells that leak into the bloodstream may help doctors more quickly and precisely treat people with severe head injuries or brain diseases, say researchers at the University of Florida's McKnight Brain Institute.

Hormone responsible for types of high blood pressure could also cause preeclampsia

Researchers at the University of Cincinnati (UC) Academic Health Center have found evidence of a hormone they say is responsible for certain types of high blood pressure (hypertension), and could also cause preeclampsia, a potentially dangerous condition that occurs during pregnancy.

New genetic discovery may help explain why some people develop high blood pressure and others don't

It also gives new insight into how the kidneys govern the balance of salt in the body, a crucial task for regulating blood pressure. And, it reveals how a gene already linked to behavior and mental health can play a role in the body, as well as the brain.

Significant step forward in the genome era

In what promises to be a significant step forward in the genome era, the National Human Genome Research Institute (NHGRI) today announced plans to devote a portion of its large-scale sequencing capacity to efforts aimed at identifying the genetic roots of specific diseases that have long eluded gene hunters.

High blood pressure is higher in many Asian countries than in Australia

A new study on risk factors in cardiovascular disease in Asia has found that blood pressure is more strongly related to coronary heart disease and stroke in Asia, as compared with Western countries such as Australia and New Zealand.

Cancer survivors have unique and long-term cancer-specific side effects.

Patients surviving childhood Hodgkin disease suffer strokes later in life at rates about four times that of the general population, UT Southwestern Medical Center researchers have found.

Combining fMRI and PET scanning creates a way to compare different measurements of the brain's function concurrently

Clinical researchers from the University of Pennsylvania Health System (UPHS) are the first to combine fMRI and PET scanning in radiology, creating a way to compare different measurements of the brain's function concurrently. This analysis could lead to better diagnosis and treatment in patients suffering from brain disorders, like Alzheimer's disease.

Very low LDL cholesterol levels appear to be safe for heart patients on statin therapies

"There was no apparent safety concern for patients whose resultant LDL on intensive therapy was lower than current guidelines. There was a trend toward improved clinical outcomes in the lowest LDL groups," said Stephen D. Wiviott, M.D., from Brigham and Women's Hospital in Boston, Massachusetts.

Astrocytes modulate adenosine - thought to be important in controlling wake-to-sleep transitions and epileptic seizures

Researchers at the University of Pennsylvania School of Medicine have demonstrated that star-shaped glial cells in the brain called astrocytes are directly involved in regulating communication between neurons.

Potential new treatment for stroke

"The study was designed to test if IL-1ra is safe in stroke patients and showed promising results," said Professor Rothwell, a world-renowned neuroscientist based in the University's Faculty of Life Sciences.

Eating fish lowers risk of dementia

Consuming fish at least once a week was associated with a 10 percent per year slower rate of cognitive decline in elderly people, according to a new study from the Archives of Neurology.

Eyes reveal risk of stroke

Looking into our eyes may help doctors predict who is at risk for stroke. A new study found that people with changes in the small blood vessels in their eyes are more likely to later suffer a stroke than people without these signs.

Recommendation that physicians be a little more cautious in deciding against tPA treatment

Although use of the clot-dissolving drug tissue plasminogen activator (tPA) has revolutionized the treatment of acute stroke patients, many of those who could receive the drug do not because their initial symptoms appear mild or improve soon after they arrive at the hospital.
