Stressed or Stressed out: What Is the Difference?

Open access
McEwen, Bruce S.·2005·Journal of Psychiatry and Neuroscience

Abstract

The term "allostasis" has been coined to clarify ambiguities associated with the word "stress". Allostasis refers to the adaptive processes that maintain homeostasis through the production of mediators such as adrenalin, cortisol and other chemical messengers. These mediators of the stress response promote adaptation in the aftermath of acute stress, but they also contribute to allostatic overload, the wear and tear on the body and brain that result from being "stressed out". This conceptual framework has created a need to know how to improve the efficiency of the adaptive response to stressors while minimizing overactivity of the same systems, since such overactivity results in many of the common diseases of modern life. This framework has also helped to demystify the biology of stress by emphasizing the protective as well as the damaging effects of the body's attempts to cope with the challenges known as stressors.

  • Both acute stress and chronic stress have been shown to exacerbate the symptoms of fibromyalgia.

    “Both acute stress, such as that experienced during traumatic events and chronic stress, such as ongoing conflict or socioeconomic hardships, have been shown to exacerbate the symptoms of fibromyalgia (McEwen 2005; Martinez‐Lavin 2007; Lahat‐Birka et al. 2024).”

    The Introduction discusses differing effects of acute and chronic stress on the brain, immune system, and cardiovascular system. A search for fibromyalgia and stress-related pain found no passage in our copy addressing whether either type of stress exacerbates fibromyalgia symptoms. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
