There are few treatments available for the millions of people who suffer from migraines. New early-stage research offers new hope.
Studies presented Tuesday at the American Academy of Neurology's annual meeting suggest that two new drugs may prevent migraines from happening.
"We've identified a new preventive treatment for migraines, something that reduces frequency, the number of attacks and severity of attacks, how bad the attacks are," said Dr. Peter Goadsby, co-author of both studies and professor of neurology at Kings College, London and the University of California, San Francisco. "The results herald a new mechanism for the preventive treatment of migraines."

In what may be another step forward in treating spinal cord injuries, a safety trial will begin this year on the practice of injecting stem cells directly into the injury site, Neuralstem Inc. announced Wednesday.
The Maryland company said the University of California, San Diego's Institutional Review Board had approved its clinical trial protocol, which also has approval from the Food and Drug Administration.
The first eight patients who will be enrolled will be paraplegics who had a thoracic spinal cord injury one to two years ago and have no motor or sensory function below the point of their spinal cord injury.
Thoracic spinal cord injuries are rare, according to the Christopher and Dana Reeve Foundation, because of the protection afforded by a person's rib cage. In addition to the loss of function in legs, patients also experience a loss of physical sensation, bowel and bladder problems and sexual dysfunction. However, in most cases, function of the arms and hands are not affected.
It's the latest trial designed to inject stem cells into patients' spines. The trial is supposed to show that the drug - stem cells, in this case - is safe, although researchers hope to provide some benefit as well. FULL POST

Nearly one-third of Americans have high blood pressure, according to the Centers for Disease Control and Prevention. When it’s not under control, it can lead to heart damage, stroke and even death.
Now new research suggests anyone with blood pressure even slightly higher than the optimal 120/80 may be more likely to have a stroke –including those patients who are diagnosed as pre-hypertensive.
The research, which is published in the Wednesday online issue of Neurology, looked at 19 studies done on the risk of developing stroke in people with "pre-hypertension," or blood pressure that falls in the gray area, between 120/80 and 140/90. More than 760,000 participants were followed for time periods ranging from four to 36 years.
The analysis found people who were pre-hypertensive were 66% more likely to develop a stroke than people who had normal blood pressure. The results were the same even when investigators adjusted for other stroke risk factors, such as diabetes and smoking.

Copper, which is found in anything from drinking water to red meats, may be an environmental trigger of Alzheimer’s disease, according to a new study.
The study, published Monday in the journal Proceedings of the National Academy of Sciences, suggests copper keeps toxic proteins from leaving the brain.
It is clear that, over time, copper impairs the systems through which amyloid beta is removed from the brain, said Rashid Deane, a research professor in the University of Rochester Medical Center Department of Neurosurgery, member of the Center for Translational Neuromedicine, and lead author of the study. This causes the protein "to accumulate in the brain and form the plaques that are the hallmark of Alzheimer's disease." FULL POST
