Alzheimer's Infects Neuron To Neuron
2012-06-27 09:51:55

The inexorable spread of Alzheimer's disease through the brain leaves dead neurons and forgotten thoughts in its wake. Researchers at Linköping University in Sweden are the first to show how toxic proteins are transferred from neuron to neuron. Through experiments on stained neurons, the research team — under the leadership of Martin Hallbeck, associate professor of Pathology — has been able to depict the process of neurons being invaded by diseased proteins that...

(Ivanhoe Newswire) — More than 15,000 Americans have Huntington´s disease, a fatal condition marked by uncontrolled movements and cognitive and psychiatric problems. Currently, there are no available treatments to alter the effects of Huntington´s disease, but a new study brings researchers one step closer to finding one. A new gene-silencing strategy can reverse core symptoms associated with Huntington's disease, according to a preclinical study. The short-term therapy...

A new gene-silencing strategy can reverse core symptoms associated with Huntington's disease, according to a preclinical study published by Cell Press in the June 21st issue of the journal Neuron. The short-term therapy produced sustained benefits in both mouse and primate animal models of this neurodegenerative disorder, which currently lacks an effective treatment. "Our approach is feasible for development now into a therapy for Huntington's disease in man," says senior study author Don...

Innovative technique expected to play a critical role in diagnosis and treatment of disease The Mount Sinai Medical Center is the first institution in New York State to use in the clinical setting a newly approved imaging technique to detect Alzheimer's disease (AD) in people who are cognitively impaired. Until now, physicians have been limited in their ability to diagnose AD, guided almost exclusively by a patient's mental and behavioral symptoms and family history. The innovative...

World-class performers in management, sports and music often have uniquely high mind-brain development Scientists trying to understand why some people excel – whether as world-class athletes, virtuoso musicians, or top CEOs – have discovered that these outstanding performers have unique brain characteristics that make them different from other people. A study published in May in the journal Cognitive Processing found that 20 top-level managers scored higher on three measures...

Has your memory failed you today, such as struggling to recall a word that's "on the tip of your tongue?" If so, you're not alone. New University of Michigan research indicates that "tip-of-the-tongue" errors happen often to adults ages 65-92. In a study of 105 healthy, highly-educated older adults, 61 percent reported this memory mishap. The study's participants completed a checklist of the memory errors made in the last 24 hours, as well as several other tests. About half of them...

A long-used anti-cancer drug could be a starting point to develop new treatments for the incurable nerve disease known as Lou Gehrig's disease or amyotrophic lateral sclerosis (ALS), scientists are reporting. Their research showing how the drug prevents clumping of an enzyme linked to ALS appears in the Journal of the American Chemical Society. Lucia Banci, Ivano Bertini and colleagues explain that ALS causes a progressive loss of muscle control as the nerves that control body movements...

(Ivanhoe Newswire) — Stem cells have the ability to create incredible breakthroughs within the medical world. Stem cells have the remarkable potential to make themselves into almost any cell within the human body during the early stages of life. Scientists at the Gladstone Institutes have for the first time transformed skin cells into a functional network of brain cells. The research offers new hope in the fight against many neurological conditions because scientists expect that such...
