A recent study found that women who use oral contraceptives and smoke have significantly greater cardiovascular reactivity to stress, as well as increased lipid and fibrinogen levels. This can lead to a higher risk of heart disease.
A study suggests that maternal stress and stress hormones may influence fetal brain development. Research found associations between maternal factors, such as medical and psychological stress, and fetal brain function.
A study by Duke University Medical Center scientists found that habitual coffee drinkers experienced increased adrenaline, noradrenaline, and blood pressure when consuming caffeine. This heightened response can lead to damage in the heart over time.
A cross-cultural study of over 200 children with specific language impairment found that their native language affects the number and types of problems they face. The study suggests that creative use errors and grammatical principles are key to understanding the disorder, which prevents millions of children from keeping up in the class...
A University of Colorado at Boulder study found that rats who exercised regularly before stress exposure were protected against its suppressive effect on immune response. Regular exercise in moderation can help buffer the negative effects of stress on the immune system, according to the researcher.
A recent study of nearly 400 South Carolina women reveals that serious crime victims are at a high risk of developing post-traumatic stress disorder (PTSD) and other emotional disorders. The effects were strongest for rape and life-threatening crimes, with robbery and burglary not linked to an increased risk.
Researchers found that athletes in a cognitive-behavioral stress management group experienced significant reductions in depressed mood, fatigue, and serum cortisol. These findings suggest that stress management programs can be an effective way to support athletes' mental health during intense training periods.
Researchers found distinct patterns of gene expression linking cognitive control regions to stress control regions in laboratory animals. The study suggests that the brain controls stress responses through inhibition, rather than excitation, and may lead to the development of future stress intervention strategies.
Researchers at Northwestern University have identified a new regulatory molecule, HSBP-1, that regulates the production of heat shock proteins in response to stress. This finding may lead to new insights into cell death associated with aging and diseases such as heart disease and stroke.
A study published in Nature Genetics found that mice deficient in a stress hormone receptor exhibit reduced anxiety and improved stress response. The research suggests that new drugs suppressing the receptor's function may be effective in treating depression and anxiety.
Traumatic stress triggers an intricate response in the body's biochemical equilibrium, affecting the brain, endocrine, and immune systems. Research aims to understand this process to create more effective treatments for related disorders.
Researchers at Ohio State University have developed a new psychoeducation program that helps families deal with children diagnosed with depression, dysthymic disorder, and bipolar disorder. The program has shown early signs of improvement in parents' understanding of their child's mood disorder and family interactions.
Researchers found that lower precombat and current intelligence were associated with PTSD symptoms among Vietnam veterans. Lower intelligence may lead to increased feelings of overwhelm and helplessness, increasing the risk for chronic PTSD.
Researchers identify eight physical indicators of stress, including blood pressure and cortisol levels, that can predict deadly consequences. Exercise is shown to be an effective antidote to break the cycle of chronic stress and its associated health problems.
Carnegie Mellon researcher Sheldon Cohen suggests that stress reduction may alter immune function, which could lead to better defenses against cancer. However, the evidence for this link is still incomplete, and more research is needed to confirm its validity.
A recent study by Ohio State University suggests that stress levels can motivate smokers to think about quitting. Contrary to popular belief, high stress does not discourage smokers but rather heightens their awareness of the health risks associated with smoking.
A UT Southwestern researcher has re-examined reports of stress in Gulf War veterans, finding minimal support for the theory that symptoms are stress-related. The data suggests a very low prevalence of post-traumatic stress disorder (PTSD) among Gulf War veterans.
A CWRU study reveals a correlation between heavy TV viewing and increased levels of anxiety, depression, anger, posttraumatic stress, and dissociation among third through eighth grade students. The study suggests that excessive screen time may exacerbate existing mental health issues in children.
A Case Western Reserve University study of 2,244 youngsters ages 8-14 found that those with the greatest exposure to violence are at high risk for severe psychological trauma. The study investigated the relationship between violence exposure and symptoms of anxiety, depression, anger, posttraumatic stress, and dissociation.
A Duke University study found that working mothers' stress hormone levels increase even with just one child at home, putting them at a higher risk for health problems. The study also showed that the number of children does not affect stress levels, and that quality of work and family experiences may be key factors in stress levels.
Researchers found a significant link between maternal cigarette smoking and conduct disorder in boys, with 80% of sons of smokers developing the condition. The study suggests that nicotine may disrupt fetal brain development, highlighting the importance of preventing such disorders.
