When a person has a cold, their throat becomes inflamed. This type of inflammation is the body&#8217;s natural and protective response to injury.<\/p>\n<p>Interestingly, there is growing evidence that <strong>a similar process happens when a person experiences psychological trauma. Unfortunately, this type of inflammation can be destructive.<\/strong><\/p>\n<p>Previous studies have linked depression and inflammation, particularly in individuals who have experienced early childhood adversity, but overall, findings have been inconsistent. Researchers Gregory Miller and Steve Cole designed a longitudinal study in an effort to resolve these discrepancies, and their findings are now published in a study in <em>Biological Psychiatry<\/em>.<\/p>\n<p>They recruited a large group of female adolescents who were healthy, but at high risk for experiencing depression. The volunteers were then followed for 2 \u00bd years, undergoing interviews and giving blood samples to measure their levels of C-reactive protein and interleukin-6, two types of inflammatory markers. Their exposure to childhood adversity was also assessed.<\/p>\n<p>The researchers found that <strong>when individuals who suffered from early childhood adversity became depressed, their depression was accompanied by an inflammatory response<\/strong>. In addition, among subjects with previous adversity, high levels of interleukin-6 forecasted risk of depression six months later. <strong>In subjects without childhood adversity, there was no such coupling of depression and inflammation<\/strong>.<\/p>\n<p>Dr. Miller commented on their findings: &#8220;What&#8217;s important about this study is that it identifies a group of people who are prone to have depression and inflammation at the same time. That group of people experienced major stress in childhood, often related to poverty, having a parent with a severe illness, or lasting separation from family. As a result, these individuals may experience depressions that are especially difficult to treat.&#8221;<\/p>\n<p>Another important aspect to their findings is that <strong>the inflammatory response among the high-adversity individuals was still detectable six months later, even if their depression had abated, meaning that the inflammation is chronic rather than acute<\/strong>. &#8220;Because chronic inflammation is involved in other health problems, like diabetes and heart disease, it also means they have greater-than-average risk for these problems. They, along with their doctors, should keep an eye out for those problems,&#8221; added Dr. Miller.<\/p>\n<p>&#8220;This study provides important additional support for the notion that inflammation is an important and often under-appreciated factor that compromises resilience after major life stresses. It provides evidence that these inflammatory states persist for long periods of time and have important functional correlates,&#8221; said Dr. John Krystal, Editor of <em>Biological Psychiatry<\/em>.<\/p>\n<p>Further research is necessary, to extend the findings beyond female adolescents and particularly in individuals with more severe, long-term depression. However, findings such as these may eventually help doctors and clinicians better manage depression and medical illness for particularly vulnerable patients.<\/p>\n<p>&nbsp;<\/p><\/blockquote>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>From the Elsevier press release via EurekAlert!: When a person injures their knee, it becomes inflamed.
