Narcissism has a higher health cost for men The personality trait narcissism may have an especially negative effect on the health of men, according to 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," says Sara Konrath, a University of Michigan psychologist who co-authored the study. Earlier studies by Konrath and others have shown that the level of...

Neuroscience researchers from Tufts identify potential target for drug therapy for wide range of disorders associated with stress Neuroscience researchers from Tufts have demonstrated, for the first time, that the physiological response to stress depends on neurosteroids acting on specific receptors in the brain, and they have been able to block that response in mice. This breakthrough suggests that these critical receptors may be drug therapy targets for control of the stress-response...

Cortisol may be the Swiss Army knife of hormones in the human body-just when scientists think they understand what it does, another function pops up. While many of these functions are understood for adults, much less is known about how cortisol operates in babies and toddlers, especially when it comes to an important phenomenon called the cortisol awakening response, or CAR. For the first time, psychology researchers from the University of Georgia Franklin College of Arts and Sciences have...

Psychobiological studies investigating the nature of the stress response and its relations to human health and development have routinely measured salivary cortisol to assess the response of the hypothalamic-pituitary-adrenal (HPA) axis. Current theory suggests, however, that measurement across multiple stress systems will provide a more complete picture of the stress response, and Salimetrics now recommends that stress-related studies should include measures of both salivary cortisol and...

Scientist identify signaling system in the brain responsible for involuntary loss of muscle mass; drugs that regulate this system are already in development Patients with cancer, heart disease and other chronic illness struggle not only with complications inherent to their disease, they also experience an involuntary loss of weight and muscle mass triggered by the body's natural response to infection and inflammation. Increasing nutrition intake does not mitigate the process and there is...

Exhaustion syndrome, also called burnout and exhaustion depression, leaves objectively measurable changes in the brain "“ including reduced activity in the frontal lobes and altered regulation of the stress hormone cortisol. This is shown in a new dissertation from UmeÃ¥ University in Sweden. Certain personality traits heighten susceptibility to psychiatric disorders. Therefore a research team at UmeÃ¥ University wanted to study whether this patient...

Whether it's food or sex, pleasurable activity provides more than just pleasure, University of Cincinnati (UC) researchers say. It actually reduces stress by inhibiting anxiety responses in the brain. The findings were published online Nov. 8, 2010, ahead of print in PNAS, the official journal of the National Academy of Sciences. Experiments designed by Yvonne Ulrich-Lai, PhD, research assistant professor, James Herman, PhD, director of the Laboratory of Stress Neurobiology and professor of...

Scientists at the University of Liverpool have found that high levels of a stress hormone in recovering alcoholics could increase the risk of relapse. The study showed that cortisol, a hormone produced by the adrenal gland in response to stress, is found in high levels in chronic alcoholics, as well as those recovering from the condition. Researchers found that this could result in impaired memory, attention and decision-making functions, which could decrease the patient's ability to engage...

Study finds hippocampus is affected by imbalance in neuroendocrine system Adding to all that ails people managing their multiple sclerosis is depression "• for which MS sufferers have a lifetime risk as high as 50 percent. Yet despite its prevalence, the cause of this depression is not understood. It's not related to how severe one's MS is, and it can occur at any stage of the disease. That suggests it is not simply a psychological reaction that comes from dealing with the burden of a...
