Brett Smith for redOrbit.com - Your Universe Online While cognitive decline is a relatively normal part of the aging process, some factors could amplify or speed up that process. Working with laboratory rats, researchers at the University of Iowa have found that the stress hormone cortisol could be one of those factors contributing to cognitive decline, according to a new report published in the Journal of Neuroscience. The UI study team found that elevated amounts of cortisol slowly...

Concerned about the effect of stress on your health and well-being? If your answer is "yes," then Arizona State University Professor Doug Granger is doing research that could impact you. Granger is pioneering the field of interdisciplinary salivary bioscience using spit. Spit conjures a variety of saying and images for most people, but for Granger and colleagues spit is also serious business. "The use of oral fluid as a research and diagnostic specimen has tremendous potential," says...

Understanding the molecular underpinnings of an ancient Chinese therapy's success could increase its acceptance by mainstream medicine While acupuncture is used widely to treat chronic stress, the mechanism of action leading to reported health benefits are not understood. In a series of studies at Georgetown University Medical Center (GUMC), researchers are demonstrating how acupuncture can significantly reduce the stress hormone response in an animal model of chronic stress. The latest...

Researchers at Warwick Medical School have discovered a way of identifying which women are most at risk of postnatal depression (PND) by checking for specific genetic variants. The findings could lead to the development of a simple, accurate blood test which checks for the likelihood of developing the condition. Presenting the research to the International Congress of Endocrinology/European Congress of Endocrinology, Professor Dimitris Grammatopoulos, Professor of Molecular Medicine at the...

After we sense a threat, our brain center responsible for responding goes into gear, setting off a chain of biochemical reactions leading to the release of cortisol from the adrenal glands. Dr. Gil Levkowitz and his team in the Molecular Cell Biology Department have now revealed a new kind of ON-OFF switch in the brain for regulating the production of a main biochemical signal from the brain that stimulates cortisol release in the body. This finding, which was recently published in Neuron,...

A new study in Biological Psychiatry answers Stress has numerous detrimental effects on the human body. Many of these effects are acutely felt by the sufferer, but many more go 'unseen', one of which is shortening of telomere length. Telomeres are protective caps on the ends of chromosomes and are indicators of aging, as they naturally shorten over time. However, telomeres are also highly susceptible to stress and depression, both of which have repeatedly been linked with premature...

Scientists now have a better understanding of the way that stress impacts the brain. New research, published by Cell Press in the January 26 issue of the journal Neuron, reveals pioneering evidence for a new mechanism of stress adaptation and may eventually lead to a better understanding of why prolonged and repeated exposure to stress can lead to anxiety disorders and depression. Most stressful stimuli cause the release of corticotropin-releasing hormone (CRH) from neurons in the brain....

(Ivanhoe Newswire) -- Narcissism is a personality trait that is defined by an inflated sense of grandiosity, self-importance, and overestimations of uniqueness. A University of Michigan psychologist, Sara Konrath, was quoted as saying in a recent study published in PLoS One, "Narcissistic men may be paying a high price in terms of their physical health, in addition to the psychological cost to their relationships." The study shows that the level of narcissism is rising in the United States...
