• DNA modifications measured in blood signal related changes in the brain

  Posted:Tue, 08 Apr 2014 12:19:18 EDT

  Researchers say they have confirmed suspicions that DNA modifications found in the blood of mice exposed to high levels of stress hormone — and showing signs of anxiety — are directly related to changes found in their brain tissues. Scientists say this research offers the first evidence that epigenetic changes that alter the way genes function without changing their underlying DNA sequence -- and are detectable in blood -- mirror alterations in brain tissue linked to underlying psychiatric diseases.

• One in three intensive care survivors develop depression that typically manifests as physical symptoms

  Posted:Sun, 06 Apr 2014 21:44:11 EDT

  A third of intensive care patients develop depression that typically manifests as physical, or somatic, symptoms such as weakness, appetite change, and fatigue, rather than psychological symptoms, according to one of the largest studies to investigate the mental health and functional outcomes of survivors of critical care.

• Gulf war illness not in veterans' heads but in their mitochondria

  Posted:Thu, 27 Mar 2014 22:22:10 EDT

  Veterans of the 1990-91 Persian Gulf War who suffer from “Gulf War illness” have impaired function of mitochondria – the energy powerhouses of cells, researchers have demonstrated for the first time. The findings could help lead to new treatments benefitting affected individuals -- and to new ways of protecting servicepersons (and civilians) from similar problems in the future.

• Use of mood-stabilizing drug linked with reduced risk of developing head and neck cancer

  Posted:Mon, 24 Mar 2014 09:04:12 EDT

  A new study indicates that a commonly used mood stabilizing drug may help prevent head and neck cancer. Valproic acid (VPA) is currently prescribed as an anti-seizure medication and mood stabilizer, but it is also being studied as an anticancer agent because it inhibits histone acetyl transferases, which help control gene expression by changing DNA structure.

• Suppressing unwanted memories reduces their unconscious influence on behavior

  Posted:Tue, 18 Mar 2014 09:39:10 EDT

  Researchers have shown that, contrary to what was previously assumed, suppressing unwanted memories reduces their unconscious influences on subsequent behavior, and have shed light on how this process happens in the brain.

• New cell type is implicated in epilepsy caused by traumatic brain injury

  Posted:Tue, 11 Mar 2014 10:03:16 EDT

  Traumatic brain injury is a risk factor for epilepsy. A new study identifies increased levels of a specific neurotransmitter as a contributing factor. The findings suggest that damage to a specific type of brain cell plays a role in the development of epilepsy after a traumatic brain injury.

• Key breaking point involved in traumatic brain injury modeled by researchers

• Returning vets face 'warring identities' distress

  Posted:Thu, 06 Mar 2014 15:24:06 EST

  Soldiers returning home from war may find themselves engaged in an even tougher conflict. A new paper examines the 'warring identities' many veterans confront when transitioning from soldier to civilian life. "You can't really do research on veterans mental health without some kind of dialogue on PTSD, but we're trying to move away from the standard PTSD framework to contextualize the veteran experience and get a more accurate picture of what vets returning from war look like as opposed to just looking at the medical side of things," the author said.

• Japanese Town: Half the survivors of mega-earthquake, tsunami, have PTSD symptoms

  Posted:Thu, 06 Mar 2014 09:55:26 EST

  A new study shows that more than half the survivors in one Japanese town exhibited 'clinically concerning' symptoms of PTSD following the country's mega-earthquake and tsunami. Two-thirds of survivors also reported symptoms of depression. Having work to do has proven important in increasing resilience.

• Experiential avoidance increases PTSD risk following child maltreatment

  Posted:Wed, 05 Mar 2014 12:52:39 EST

  Child abuse is a reliable predictor of post-traumatic stress disorder, but not all maltreated children suffer from it, according researchers, who examined why some maltreated children develop PTSD and some do not. The research team found that adolescent girls who experienced maltreatment in the past year and were willing to talk about their painful experiences and their thoughts and emotions, were less likely to have PTSD symptoms one year later. Those who tried to avoid painful thoughts and emotions were significantly more likely to exhibit PTSD symptoms down the road.

• Drug war violence in Mexico connected with desensitization in social media

  Posted:Tue, 04 Mar 2014 15:45:25 EST

  Amid times of crisis, citizens often turn to social media as a method to share information, make observations and vent. But as a professor’s research into social media use amid the Mexican drug war shows, posts can reveal growing numbness, or desensitization, during times of protracted violence and stress.

• Military dads have to re-learn parenting after deployment

  Posted:Tue, 04 Mar 2014 14:16:37 EST

• Poor sleep quality linked to reduced brain gray matter in Gulf War vets

  Posted:Fri, 28 Feb 2014 16:06:18 EST

  A new study of Gulf War veterans found an association between poor sleep quality and reduced gray matter volume in the brain's frontal lobe, which helps control important processes such as working memory and executive function. "This study emphasizes the importance of seeking medical help if you are troubled by the poor quality of your sleep," said American Academy of Sleep Medicine President. "A board certified sleep medicine physician can identify the cause of your sleep problem and develop an effective treatment plan for you."

• Mental health of most UK troops serving in Afghanistan, Iraq is 'resilient'

  Posted:Wed, 26 Feb 2014 21:12:35 EST

  Despite prolonged combat missions to Iraq and Afghanistan, there has been no overall increase in mental health problems among United Kingdom soldiers, finds a review of the available evidence. But certain groups of soldiers do seem to be more vulnerable to mental ill health on their return home, while alcohol problems continue to give cause for concern among regulars. The researchers focused on Iraq and Afghanistan because of the lengthy and challenging nature of the conflict experienced by British soldiers in these two countries, including protracted counter insurgency and repeated exposure to improvised explosive devices (IEDs), snipers, and suicide bombers. Their analysis, which draws on 34 studies, shows that, overall, most UK regulars returning from deployment have remained psychologically resilient, despite the adversities they faced.

• Could PTSD involve immune cell response to stress? Study in mice raises question

  Posted:Thu, 20 Feb 2014 19:33:33 EST

  Chronic stress that produces inflammation and anxiety in mice appears to prime their immune systems for a prolonged fight, causing the animals to have an excessive reaction to a single acute stressor weeks later, new research suggests. After the mice recovered from the effects of chronic stress, a single stressful event 24 days later quickly returned them to a chronically stressed state in biological and behavioral terms. Mice that had not experienced the chronic stress were unaffected by the single acute stressor.

• New pathway for fear discovered deep within brain

  Posted:Wed, 12 Feb 2014 13:28:03 EST

  Fear is primal. In the wild, it serves as a protective mechanism, but for humans, fear is more complex. A normal amount keeps us safe. But too much fear, like PTSD, can prevent people from living healthy lives. Researchers are working to understand how the brain translates fear into action. Today, scientists announce the discovery of a new neural circuit that links the site of fear memory with a brain area that controls behavior.

• Examination of clinical, policy implications of intimate partner violence

  Posted:Wed, 12 Feb 2014 11:27:55 EST

  Intimate partner violence (IPV) is a serious public health concern for all, however women who experience IPV are more likely to sustain injury and report adverse health consequences. An expanding body of research suggests that experience of IPV is common in women veterans, particularly those who access Veterans Health Administration services.

• How chronic stress predisposes brain to mental disorders

  Posted:Tue, 11 Feb 2014 15:35:59 EST

  Biologists 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.

• Understanding fear means correctly defining fear itself

  Posted:Tue, 04 Feb 2014 11:18:10 EST

  Understanding and properly studying fear is partly a matter of correctly defining fear itself. New analysis points to ways research can be better geared to address a range of fear-related afflictions, such as post-traumatic stress syndrome (PTSD) and commonly experienced phobias.

• Sniffing out danger: Fearful memories can trigger heightened sense of smell

  Posted:Thu, 12 Dec 2013 14:22:15 EST

  Neuroscientists studying the olfactory -- sense of smell -- system in mice have discovered that fear reaction can occur at the sensory level, even before the brain has the opportunity to interpret that the odor could mean trouble.

• High levels of maternal care has life-long impact on vulnerability to stress, study says

  Posted:Thu, 12 Dec 2013 10:00:43 EST

  A new study shows that high levels of maternal care during the early post-natal period in rodents can reduce the sensitivity of the offspring to stressful events during adulthood. Maternal care is shown to chemically modify and thereby re-program genes that control stress responses, making them less likely to be activated. The findings have important implications for understanding early environment influences on stress-related disorders.

• Brain trauma raises risk of later PTSD in active-duty marines

  Posted:Wed, 11 Dec 2013 18:38:07 EST

  In a novel study of U.S. Marines investigating the association between traumatic brain injury (TBI) and the risk of post-traumatic stress disorder (PTSD) over time, a team of scientists report that TBIs suffered during active-duty deployment to Iraq and Afghanistan were the greatest predictor for subsequent PTSD, but found pre-deployment PTSD symptoms and high combat intensity were also significant factors.

• Conflict zone contractors suffer high rates of PTSD, depression

  Posted:Tue, 10 Dec 2013 07:21:23 EST

  Private contractors who worked in Iraq, Afghanistan or other conflict environments over the past two years report suffering from post-traumatic stress disorder and depression more often than military personnel who served in recent conflicts, according to a new study.

• Hypersensitivity to pain produced by early life stress worsened by later stress exposure

  Posted:Tue, 05 Nov 2013 08:13:54 EST

  Childhood neglect and abuse, whether physical or psychological, confers a lifetime vulnerability to stress, anxiety, and mood problems. Such early-life stress is also suspected to contribute to the development of chronic pain in adulthood. In fact, there is growing concern that chronic pain syndromes may be a complication of posttraumatic stress disorder (PTSD). However, this link is particularly challenging to study because many stressful events that produce PTSD also produce physical trauma.

• Stem cells linked to cognitive gain after brain injury
