    The Darker Side Of Serotonin Finally Exposed - It Increases Anxiety And Suicide

    I guess the fact that such studies are finally starting to come out is a good sign. I don't think this will hurt Prozac sales in any way, but at least now doctors may start to discuss with patients the potential dangers of SSRI, which up until last year were considered to be pure myth. It still...

    Self-reported Health Much Better Predictor Than "objective" Tests

    I like this study for a number of reasons. First, it validates the idea that the patient knows quite well when something is plaguing them despite the current approach to ignore completely self-reported symptoms. Second, it confirms the connection between stress and inflammation, and viral...

    A (chronic) Very Low Dose Endotoxin Exposure Might Be As Dangerous As An Acute One

    Treehuggers, @haidut forced me to post this study with the following comments: This, unlike the majority of studies on the effects of LPS, was done using a very low dose of endotoxin; according to them, something that is compatible with the circulating levels seen in chronic metabolic...

    Emotional Stress Linked To Diabetes

    Considering the direct connection between stress, cortisol, and insulin resistance, I think the link should not be surprising but apparently it is to the fellows in white coats. http://www.psyneuen-journal.com/article/S0306-4530%2816%2930134-2/abstract Stress-diabetes link detailed in new study...

    The Myth Of Pregnenolone Steal

    I think this is a very persistent myth and one that is reigning supreme on all forums except this one. Even here, we occasionally get challenged and statements referring to this flawed idea. Here is something that will hopefully clarify why the steroid "steal" is a flawed idea. Among the more...

    Pregnenolone May Protect Cognition From Damage By Stress

    The study was actually on how stress damages cognition, and based on another study I posted and the drug used in the study to block the effects of stress I inferred that pregnenolone would work just as well. The study discovered that the release of CRF / CRH as part of the stress response is...

    Stress Increases Estrogen In Females And Impairs Cognitive Function

    Mothers Can Transmit Psychiatric Issues (due To Stress) To Their Children / Grandchildren

    As Ray said, at birth we are a mix of the stress blueprint of our parents, grandparents, and great-grandparents. It is up to us to do what we can to change this blueprint for the better. At the very least, the inheritance landscape is looking a lot more Lamarckian these days. The Human Genome...

    Circadian Clock Dysruptions Driven By Adrenal Activity (cortisol)

    Stress Increases Risk For Alzheimer Disease (AD)

    This is probably not surprising for any forum user, but official medical guidelines still claim that stress has no known long-term direct effects on health except in "genetically-predisposed individuals".

    Striving To Improve Social/Financial Status Negatively Affects Health

    It is a mantra we hear on TV every day - "work harder and you will live better". While that may be true in terms of financial success, it looks like that success does not come without a price. And the price is worse health due to the stress endured in order to climb the social ladder...

    Prolactin Increases Cortisol Secretion

    I think this is a pretty important study as it provides further evidence of the close relationship between various biomarkers of stress such as prolactin, estrogen, and cortisol. As Ray said, estrogen is really not a female hormone but rather the stress hormone. Prolactin is pretty similar, and...
