After reading more on stress and inflammation in the immune response I came across the term Psychoneuroimmunology which describes the relationship between the brain and the immune system. We had read a few lay articles on stress, particularly the study on how social stresses exacerbated the symptoms of Multiple Sclerosis. There is actually an organization committed to this specific field called the Psychoneuroimmunology Research Society and I have included their website below. Also, it seems that may medical schools and health care facilities have specific research units dedicated to this field. I have posted another paper on the concerns and difficulties that are involved in the field including measurement of psychological parameters and the effect of the environment on a subject.
