A new study from the Swedish medical university Karolinska Institutet shows that infants with low concentrations of the stress-related hormone cortisol in their saliva develop fewer allergies than other infants. Hopefully this new knowledge will be useful in future allergy prevention. The study is published in the December paper issue of Journal of Allergy and Clinical Immunology.
People with recurrent depression or those exposed to chronic stress exhibits shorter telomeres in white blood cells. This is shown by a research team at Umeå University in a coming issue of Biological Psychiatry. The telomere is the outermost part of the chromosome. With increasing age, telomeres shorten, and studies have shown that oxidative stress and inflammation accelerates this shortening.
If you are pregnant, here is another reason to work out: you will reduce the chances of your new baby developing neurodegenerative diseases, such as Alzheimer’s, later in life. A new research report published online in The FASEB Journal shows that mice bred to develop a neurodegenerative disease roughly equivalent to Alzheimer’s disease showed fewer [...]
Psychosocial stress could play a role in the etiology of breast cancer aggressiveness, particularly among minority populations, according to study results presented at the Fourth AACR Conference on The Science of Cancer Health Disparities, held here from Sept. 18-21, 2011.
Is your kid a “dove” – cautious and submissive when confronting new environments, or perhaps you have a “hawk” – bold and assertive in unfamiliar settings? These basic temperamental patterns are linked to opposite hormonal responses to stress – differences that may provide children with advantages for navigating threatening environments, researchers report in a study published online July 8, 2011, in Development and Psychopathology.
Intense distress and fear of dying, which many people experience when suffering the symptoms of a heart attack, are not only fairly common emotional responses but are also linked to biological changes that occur during the event, according to new research published online today in the European Heart Journal [1]. These changes, in turn, are associated with other biological processes during the following weeks that can predict a worse outcome for patients.
A notable prevalence of childhood abuse – physical, sexual, verbal, or emotional – in migraine patients has been observed and documented over the last few years. In fact, it has emerged as a significant enough issue for the American Headache Society to devote an entire plenary session to it at its annual scientific conference in Washington this week.
This recent series of posts has used the example of Stephen Colbert’s satirical “March to Keep Fear Alive” as an illustration of a larger point: humans evolved to be fearful – a major feature of the brain’s negativity bias that helped our ancestors pass on their genes. Consequently, as much research has shown, we’re usually much more affected by negative – by which I mean painful – experiences than by positive ones.
Contrary to earlier reports, a new study finds that stress does not appear to increase a person’s risk of developing multiple sclerosis (MS). The research is published in the May 31, 2011, print issue of Neurology, the medical journal of the American Academy of Neurology.
For the first time, researchers at McMaster University have conclusive evidence that bacteria residing in the gut influence brain chemistry and behavior. The findings are important because several common types of gastrointestinal disease, including irritable bowel syndrome, are frequently associated with anxiety or depression. In addition, there has been speculation that some psychiatric disorders, such as late onset autism, may be associated with an abnormal bacterial content in the gut. The research appears in the online edition of the journalGastroenterology.
