    Haven't read the study properly, but the abstract says something like this (not sure if I managed the "simple", though):

    Basicly they looked at methylation at certain CpG islands found in the promoter area of TRPA1. They found that an increase in methylation at CpG -628 and -411 led to a higher tolerance for for pain. Methylation is the process of adding a methyl group to something, in this case a certain part of the DNA called a CpG island. They found that the more methylation a person has at site -628 and -411 the higher their tolerance for pain is.

    They then looked at methylation patterns and compared them to levels of childhood trauma. In controls the levels of methylation didn't differ between people with and without trauma, but in patients of MSD they found that those who had experienced trauma had lower levels of methylation.

    So in healthy people childhood trauma did not cause a decrease in methylation (didn't make them more likely to experience pain?) but they suggest that this might be the case with people who receive a MSD diagnosis.

    So childhood trauma does not lead to more pain sensitivity but being ill does. Yet they have manage to bend these results to say that childhood trauma leads to functional somatic syndromes!

    "We found correlation and argue that it means causation"

    This table shows clear problems with any correlation with trauma, a very subjective self-assessment, since there are variations in chronic pain patients with no trauma compared to controls. The hypothesis should mean no difference and yet there is, likely down to the imprecise nature of assessing whatever people may mean by trauma. This is just fishing for some way to rationalize a predetermined belief that trauma is a significant causative factor in chronic pain.

    Basically they found nothing of significance but argue they did because they want to do more research and reporting null results does not favor that. Should be referred to remedial science 101. Instead this will likely lead to more funding. Typical.

    if you cannot dress garbage in twenty dollar words then you have no future in psychology . or baffling people with imprecise language can be great for your bank account . all this tripe just makes me ill .

    The abstract does not even say which cells the methylation was in. I doubt they checked brain cells.

    I don't suppose that there would be any reason to think nucleated blood cells and whatever else is floating around tell us much about relevant nervous functioning in this case.
