  1. Some studies have shown that stress has many effects on the human nervous system and can cause structural changes in different parts of the brain (Lupien et al., 2009 [65]). Chronic stress can lead to atrophy of the brain mass and decrease its weight (Sarahian et al., 2014 [100]).

  2. Oct 17, 2020 · Stress constitutes a state of threatened homeostasis triggered by intrinsic or extrinsic adverse forces (stressors) and is counteracted by an intricate repertoire of physiologic and behavioral responses aiming to maintain/reestablish the optimal body equilibrium (eustasis). The adaptive stress response depends upon a highly interconnected neuroendocrine, cellular, and molecular infrastructure ...

  3. Environmental stress and stress hormones such as glucocorticoids are tightly coupled with behavioral and physiological components of energy homeostasis in humans and non-human animals. At the whole-organism level, environmental stress leads to reductions in impulse control, changes in food intake, and dysregulated metabolic states.

  4. May 7, 2024 · Any physical or psychological stimuli that disrupt homeostasis result in a stress response. The stimuli are called stressors, and physiological and behavioral changes in response to exposure to stressors constitute the stress response. A stress response is mediated through a complex interplay of nervous, endocrine, and immune mechanisms, activating the sympathetic-adreno-medullar (SAM) axis ...

  5. Jan 1, 2022 · Abstract. Stress is an environmental factor that precipitates a potent physiological response involving the autonomic nervous system and the hypothalamic-pituitary-adrenal (HPA) axis. The modern society has posed unprecedented challenges for the human stress experience, as chronic stress exposure, which has become an integral part of societal ...

  6. The brain is the key organ of the response to stress because it determines what is threatening and, therefore, potentially stressful, as well as the physiological and behavioral responses which can be either adaptive or damaging. Stress involves two-way communication between the brain and the cardiovascular, immune, and other systems via neural and endocrine mechanisms. Beyond the “flight-or ...

  7. The recognition that chronic stress can cause serious diseases has intensified research to determine the biochemical perturbations that compromise homeostasis to a degree that prevents spontaneous recovery. The picture is very complex because chronic stress appears to affect organ and system functions at multiple levels.
