(Press-News.org) SAN DIEGO — New research is providing a deeper understanding of how individual actions — such as exercising, sensory stimulation, or drinking — influence brain health and outcomes. This new knowledge could ultimately lead to interventions in age-related cognitive declines, drug abuse, stroke, and brain injury, separate from or in combination with traditional pharmacological approaches. These findings were presented at Neuroscience 2010, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news on brain science and health.
Specifically, today's new findings show that:
Mild sensory stimulation within the first two hours of stroke may be a life-saving intervention before patients reach emergency rooms. Research showed whisker stimulation in rats protected against brain damage and restored function (Ron Frostig, PhD, abstract 14.10, see attached summary).
Musical training may help mitigate age-related hearing loss, suggesting that the old adage "use it or lose it" applies to hearing (Benjamin Zendel, abstract 481.14, see attached summary).
Aerobic exercise lessens excessive cocaine use in rats. The findings suggest physical activity may be helpful in treating or preventing drug addiction (Mark A. Smith, PhD, abstract 574.12, see attached summary).
Being physically fit prior to injury alleviated effects of traumatic brain injury in mice. This finding builds on existing research showing physical exercise after injury improves cognitive function (Jerome Badaut, PhD, abstract 356.7, see attached summary).
Other recent findings discussed show that:
Behavior and lifestyle interventions can improve brain health and function, and may be effective in slowing or preventing age-related diseases. Both human and animal studies support the effectiveness of physical activity, cognitive training, and other lifestyle changes to benefit brain health, learning, and memory (Carl Cotman, PhD, see attached speaker's summary).
"Evidence indicates that our actions have broader and more complex ties to brain function and health than previously thought," said press conference moderator Carol A. Barnes, PhD, of the Evelyn F. McKnight Brain Institute of the University of Arizona, an expert on the aging brain. "We are learning a great deal about the brain, and today can fully appreciate our own role in keeping it healthy."

SAN DIEGO —Two experimental brain-machine technologies — deep brain stimulation coupled with physical therapy and a thought-controlled computer system—may offer new therapies for people with stroke and brain injuries, new human research shows. In addition, an animal study shows a new artificial retina may restore vision better than existing prosthetics. The findings were announced today at Neuroscience 2010, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news on brain science and health.

SAN DIEGO —New animal research has identified factors, such as the stress response and immune system, that may play important roles in depression. Scientists have also found that the regulation of nerve cell signals influences depression in animals, and that new drug combinations may more effectively treat it. The findings were presented at Neuroscience 2010, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news on brain science and health.

SAN DIEGO —New research released today shows teenagers respond differently to drugs than adults and explores the long-lasting effects of drug use on brain development. One study shows people who start using drugs at a young age have greater cognitive shortfalls, including mental flexibility. Animal studies also suggest adolescents are more susceptible to lower doses of cocaine, are willing to work more for a cocaine "fix" than adults, and are at risk of developing compromised stress responses. The research findings were presented at Neuroscience 2010, the Society for Neuroscience's ...
The landform known as a drumlin, created when the ice advanced during the Ice Age, can also be produced by today's glaciers. This discovery, made by researchers from the University of Gothenburg, Sweden, has just been published in the scientific journal Geology.
Drumlins generally consist of an accumulation of glacial debris – till – and are found in areas that were covered by ice sheet. As the ice advanced, it moved rocks, gravel and sand and created tear-shaped raised ridges running parallel with the movement of the ice.
"Until now, scientists have been divided on ...
FT. LAUDERDALE-DAVIE Fla. ---- A Nova Southeastern University (NSU) researcher has announced a breakthrough discovery to block a protein that can contribute to heart failure.
His discovery will appear in an upcoming issue of the prestigious medical journal, the Journal of the American College of Cardiology.
Anastasios Lymperopoulos, Ph.D., an NSU College of Pharmacy assistant professor of pharmacology, has discovered a novel method, using gene therapy, to block the actions of a gene-encoded protein.
That protein, known as beta-arrestin 1, causes an increase of aldosterone ...
San Diego - Neuroscientists at Georgetown University Medical Center (GUMC) say brain scans show that a gene nominally linked to attention deficit hyperactivity disorder (ADHD) leads to increased interference by brain regions associated with mind wandering during mental tasks.
Presented at the annual meeting of the Society for Neuroscience, these researchers believe their findings are the first to show, through brain scanning, the differences in brain network relationships between individuals with this particular form of gene and others with a different form.
"Our goal ...
Treatment that included early surgical procedures to open blocked arteries resulted in better blood flow to the heart than aggressive medical treatment alone in patients with both diabetes and heart disease, according to a study presented at the American Heart Association's Scientific Sessions 2010.
Previously, researchers in BARI 2D (Bypass Angioplasty Revascularization Investigation 2 Diabetes) found that over five years there were no fewer deaths and heart attacks in people who had medical treatment along with prompt vessel-opening surgery (revascularization) than ...
A less invasive procedure for treating a congenital heart defect in children is a safe alternative to traditional surgery with no five-year difference in risk of death and is associated with a 62 percent reduced risk for neurological events (such as strokes or seizures), according to a study presented at the American Heart Association's Scientific Sessions 2010.
In a study of 580 children with secundum atrial septal defect (ASD), researchers evaluated the long-term safety and effectiveness of transcatheter closure versus traditional surgery. Transcatheter closure is a ...
Fat cells — liposuctioned from a patient's belly — can safely boost heart function after a heart attack, according to a first-of-its-kind study presented at the American Heart Association's Scientific Sessions 2010.
"The study suggests that these cells can be safely obtained and infused inside the hearts of patients following an acute heart attack," said Eric (HJ) Duckers, M.D., Ph.D., lead author of the small study and head of Molecular Cardiology Laboratory at the Thoraxcenter, Erasmus University Medical Center in Rotterdam, Netherlands.
The treatment reduced the amount ...
Abstract 21829 – Automated remote patient monitoring fails to improve outcomes for heart failure patients
A remote monitoring system didn't help heart failure patients live longer or avoid return trips to the hospital, according to a new study.
The system required heart failure patients to dial into an automated, interactive voice response system daily to enter their weight and answer questions about heart failure symptoms. Clinicians managing patients' heart failure reviewed the information and called patients back to discuss worrisome reports. The remote monitoring ...
