The effects of stress on memory include interference with a person's capacity to encode memory and the ability to retrieve information. [1] [2] Stimuli, like stress, improved memory when it was related to learning the subject. [3] During times of stress, the body reacts by secreting stress hormones into the bloodstream.
For instance, extreme stress (e.g. trauma) is a requisite factor to produce stress-related disorders such as post-traumatic stress disorder. [ 6 ] Chronic stress also shifts learning, forming a preference for habit based learning , and decreased task flexibility and spatial working memory , probably through alterations of the dopaminergic ...
Stress produces numerous physical and mental symptoms which vary according to each individual's situational factors. These can include a decline in physical health, such as headaches, chest pain, fatigue, sleep problems, [1] and depression. The process of stress management is a key factor that can lead to a happy and successful life in modern ...
Studies such as these reinforce the impact that the hippocampus has on memory processing, in particular the recall function of spatial memory. Furthermore, impairment to the hippocampus can occur from prolonged exposure to stress hormones such as glucocorticoids (GCs), which target the hippocampus and cause disruption in explicit memory. [22]
The hippocampus regulates memory function. Memory improvement is the act of enhancing one's memory. Factors motivating research on improving memory include conditions such as amnesia, age-related memory loss, people’s desire to enhance their memory, and the search to determine factors that impact memory and cognition.
Frequent stress: the magnitude and frequency of response to stress is what determines the level of allostatic load which affects the body. Failed shut-down: the inability of the body to shut off while stress accelerates and levels in the body exceed normal levels, for example, elevated blood pressure.

A 2007 review by Lupien at al [8] of the effects of stress hormones (glucocorticoids, GC) and human cognition revealed that memory performance vs. circulating levels of glucocorticoids does manifest an upside-down U-shaped curve, and the authors noted the resemblance to the Yerkes–Dodson curve.
