Tania, sorry to hear you have suffered so much.
I have experienced a several month lasting stress caused by my family member before getting ill, so I am in favor of the theory that stress can be one of the players to cause a an illness which unfortunately does not resolve even the person is not stressed anymore for months and years. And yes, there has to be a genetic predisposition, in my family case it is some weak expression for autoimmune diseases. Human body is created to survive stress, but most probably not a prolonged one, and the same results could be achieved by injecting test animals with all the hormones that our body produces in fight or flight response for a long time or tiring out the organs which produce the hormones by injecting some hormone annihilating chemicals.
Turning back to the article, for this study to be of any scientific significance, they should show that it correlates more with CFS, Fm and MCS than other FSS and non-FSS diseases, for example, cancer. By the way, do Canada health care institutions really classify CFS, Fm and MCS as FSS?
Even if a part of CFS, FB and MCS patients were abused in their young age (statistically it is impossible that there would not be any), the study does not provide any data (well, the abstract says this study implies an assessment of abuse) what should be done about it? Will the fact somehow lead to the cure? Did they cure anyone in this way, by pointing out they were abused? It is not helpful in any way unless they propose what to do with the people who were abused and prove this is beneficial to them.
Or do they mean now we should use this data for our awareness campaigns: "Do not abuse your small children, they will have CFS or FM or MCS and be in a lot of pain when they grow up!!!". How effective that would be?
I would recommend the authors (as they seem to lack the research ideas) to do a study about medical society abuse of CFS patients. Wouldn't it be interesting to compare patients who are taken seriously and get treated at least for symptoms and those who go through the marathon of changing from one ignorant general practitioner to another and try out GET? What is the impact of medical society attitudes for the wellbeing of patients? Specifically, what is the impact to the patient of calling a serious disabling illness a functional somatic syndrome? Are they more angry compared to other illnesses, if told the same?
In general, I think in about 50 years the medicine will have to say goodbye many psychiatric concepts. Be sure your children will not study for any similar professions, because they will lose their jobs when being middle aged (assuming they are small now).
I repost a full journal reference, so that when googled for this article/authors people also see this discussion.
