Costs to treat bleeding strokes increases 10 years later

Costs to treat bleeding strokes increases 10 years later

Costs to treat strokes caused by bleeding in the brain may increase significantly 10 years later, according to a study in the American Heart Association journal Stroke. The Australian study is the first to include 10 years of follow-up data on stroke cost estimates, which may also apply to the United States, researchers said Continue reading

Fight against Alzheimer’s disease: New research on walnuts

Fight against Alzheimer’s disease: New research on walnuts

A new animal study published in the Journal of Alzheimer’s Disease indicates that a diet including walnuts may have a beneficial effect in reducing the risk, delaying the onset, slowing the progression of, or preventing Alzheimer’s disease. Research led by Abha Chauhan, PhD, head of the Developmental Neuroscience Laboratory at the New York State Institute for Basic Research in Developmental Disabilities (IBR), found significant improvement in learning skills, memory, reducing anxiety, and motor development in mice fed a walnut-enriched diet Continue reading

Mental rest and reflection boost learning, study suggests

A new study, which may have implications for approaches to education, finds that brain mechanisms engaged when people allow their minds to rest and reflect on things they’ve learned before, may boost later learning. Continue reading

See-through sensors open new window into the brain

Developing invisible implantable medical sensor arrays, a team of University of Wisconsin-Madison engineers has overcome a major technological hurdle in researchers’ efforts to understand the brain. The team described its technology, which has applications in fields ranging from neuroscience to cardiac care and even contact lenses, in the Oct. 20 issue of the online journal Nature Communications Continue reading

New mechanism that can lead to blindness discovered

New mechanism that can lead to blindness discovered

An important scientific breakthrough by a team of IRCM researchers led by Michel Cayouette, PhD, is being published by The Journal of Neuroscience . The Montréal scientists discovered that a protein found in the retina plays an essential role in the function and survival of light-sensing cells that are required for vision. These findings could have a significant impact on our understanding of retinal degenerative diseases that cause blindness Continue reading

Scientists sniff out unexpected role for stem cells in the brain

Scientists sniff out unexpected role for stem cells in the brain

For decades, scientists thought that neurons in the brain were born only during the early development period and could not be replenished. More recently, however, they discovered cells with the ability to divide and turn into new neurons in specific brain regions. The function of these neuroprogenitor cells remains an intense area of research Continue reading

People with autism spectrum disorder often experience a period of accelerated brain growth after birth. Continue reading

Myasthenia gravis: Efficacy of potential therapy for autoimmune disorder of muscle weakness

Myasthenia gravis: Efficacy of potential therapy for autoimmune disorder of muscle weakness

Nearly 60,000 Americans suffer from myasthenia gravis (MG), a non-inherited autoimmune form of muscle weakness. The disease has no cure, and the primary treatments are nonspecific immunosuppressants and inhibitors of the enzyme cholinesterase. Now, a pair of researchers from the Perelman School of Medicine at the University of Pennsylvania have developed a fast-acting “vaccine” that can reverse the course of the disease in rats, and, they hope, in humans Continue reading

Stroke-fighting drug offers potential treatment for traumatic brain injury

Stroke-fighting drug offers potential treatment for traumatic brain injury

The only drug currently approved for treatment of stroke’s crippling effects shows promise, when administered as a nasal spray, to help heal similar damage in less severe forms of traumatic brain injury. In the first examination of its kind, researchers Ye Xiong, Ph.D, Zhongwu Liu, Ph.D., and Michael Chopp, Ph.D., Scientific Director of the Henry Ford Neuroscience Institute, found in animal studies that the brain’s limited ability to repair itself after trauma can be enhanced when treated with the drug tPA, or tissue plasminogen activator.
