Acute Stress Response Cheryl Welch Liberty University Abstract The purpose of this paper is to define and explain the acute stress response and acute stress disorder. Clarify the differences between the two conditions and offer review of treatments and symptoms associated with both. Therapies and interventions are reviewed and explored for effectiveness in resolving symptoms and preventing post-traumatic stress disorder. The acute stress response (ASR) refers to psychological and physiological responses to stressful events. These responses are displayed by emotional, cognitive, and behavioral changes. Somatic symptoms and symptoms of mental illness can also be seen in ASR especially when the reaction is severe. ASR manifests itself†¦show more content†¦(Mannironi, et al., 2013) First let us look at the amygdala’s roll in the stress response. The amygdala is made up of a group of nuclei located in the medial temporal lobe of the brain. (Mannironi, et al., 2013) The amygdala is believed to be key in stress response integration with its extensive network of efferent outcrops to other regions of the brain. (Mannironi, et al., 2013) Stress mediators such as adrenaline, cortisol, and corticotrophin releasing hormone, contribute to neuronal operative change and plasticity that are instrumental contributory to the stress response. (Mannironi, et al., 2013) Acute psychological stress creates a instant surge of hormone release, neuronal activation, and neurotransmission. (Mannironi, et al., 2013) This activation has an intense effect on the brain, leading to structural modification in the synaptic connectivity and dendritic spine morphology. (Mannironi, et al., 2013) The hormones released during the acute stress response is considered the â€Å"master switch† in controlling the person’s behavioral and physiological adaptation to stress. (Mannironi, et al., 2013) The targets of these hormones are the cognitive, wake sleep, and reward and fear centers of the brain. (Chrousos, 2009) The growth, gastrointestinal, cardiorespiratory, metabolic, reproductive and thyroid hormone axis, and immune systems are also effected.

Chronic stress, primarily mediated by the glucocorticoid cortisol, is associated with deleterious health outcomes and immune deficiency. However, acute stress is associated with protective health effects and immune enhancement. Stress has generallyRead MoreAcute Stress Responses For Healthy Individuals May Be Adaptive And Typically Do Not Impose A Health Burden Essay1974 Words   |  8 PagesAcute stress responses in young, healthy individuals may be adaptive and typically do not impose a health burden. The relationship between psychosocial stressors and disease is affected by the nature, number, and persistence of the stressors as well as by the individual s biological vulnerability (i.e., genetics, constitutional factors), psychosocial resources, and learned patterns of coping.
