New study finds connection between chronic pain and anxiety disorders
New study results provide insight into a long-observed, but little-understood connection between chronic pain and anxiety and offer a potential target for treatment. Researchers found that increased expression of PACAP -- a peptide neurotransmitter the body releases in response to stress -- is also increased in response to neuropathic pain and contributes to these symptoms. (2016-08-31)

'Tangible aid' important to black women with low incomes
Black women living in predominantly low-income neighborhoods have better health when they have someone to help them on a regular basis, according to a new study. The study also suggests that contrary to previous research, it may be that when it comes to handling stress associated with living in predominantly low-income communities, tangible aid like money, child care and transportation are more important than emotional support from friends and family.

New evidence shows how chronic stress predisposes brain to mental disorders
UC Berkeley biologist Daniela Kaufer and colleagues have shown in rats that chronic stress makes stem cells in the brain produce more myelin-producing cells and fewer neurons, possibly affecting the speed of connections between cells as well as memory and learning. This could explain why stress leads to mental illness, such as PTSD, anxiety and mood disorders, later in life. (2014-02-11)

UCLA study identifies mechanism behind mind-body connection
Immune cells end in protective caps called telomeres that are shorter in the elderly -- and in persons suffering chronic stress. A new UCLA study suggests that the hormone cortisol is the culprit behind telomeres' early aging in stressed-out people and offers a potential drug target for protecting the immune system against the damage caused by long-term stress. (2008-07-15)

New research from Carnegie Mellon University provides the first evidence that self-affirmation can protect against the damaging effects of stress on problem-solving performance. Understanding that self-affirmation -- the process of identifying and focusing on one's most important values -- boosts stressed individuals' problem-solving abilities will help guide future research and the development of educational interventions. (2013-05-03)

Preventing chronic pain with stress management
For chronic pain sufferers, such as people who develop back pain after a car accident, avoiding the harmful effects of stress may be key to managing their condition.

Study shows a bidirectional relationship between chronic stress and sleep problems
According to a research abstract that will be presented on Wednesday, June 10, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, people with chronic stress report shorter sleep duration, worse sleep quality, and more daytime functioning impairments. Conversely, daytime functioning impairments and shorter sleep duration demonstrated a predictive relationship with habitual stress complaints. (2009-06-10)

Can a brain scan early in stress predict eventual memory loss?
New research from the National Centre for Biological Sciences, Bangalore and Trinity College, Dublin, now shows that even a brief period of stress -- as few as three days -- can cause the hippocampus to start shrinking. This shrinking of the hippocampus -- a change in the brain's structure -- actually precedes the onset of a change in behavior, namely, the loss of memory. (2016-07-26)

At last, a reason why stress causes DNA damage
For years, researchers have published papers that associate chronic stress with chromosomal damage. Now researchers at Duke University Medical Center have discovered a mechanism that helps to explain the stress response in terms of DNA damage. (2011-08-21)

More detailed analysis of how cells react to stress
Stress in the body's cells is both the cause and consequence of inflammatory diseases or cancer. The cells react to stress to protect themselves. Researchers at the University of Zurich have now developed a new technique that allows studying a fundamental response to stress in much more detail than previously possible: the ADP-ribosylation of chromatin. In the long term, this method could help finding ways of blocking disease-causing processes. (2016-02-08)
