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]).

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 ...

May 7, 2024 · As the stressful event persists, the body's immune system weakens due to the suppressive effects of stress hormones on immune system cells. Systemic Effects of Stress Although the restoration of homeostasis is the goal of the stress response, chronic stress leads to dysfunctional responses, resulting in heart disease, stomach ulcers, sleep dysregulation, and psychiatric disorders.

First, inflammation can be induced as a result of extreme deviations in regulated variables of cellular and tissue homeostasis (i.e., the stress response component of inflammation). Thus, inflammation is at the extreme end of the spectrum of adaptive responses aimed to protect tissue homeostasis. Second, inflammation can be induced by agents ...
When there are significant shifts in the environment, the brain and body engage a set of physiological and behavioral countermeasures collectively known as the “stress response”. These responses, which include changes at the cellular, systems, and organismal level, are geared toward protecting homeostasis and adapting physiological ...

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 ...
