Feb 18, 2022 · "Good stress" is processed adaptively, but "bad stress" can have lasting effects on brain structure, function, and plasticity that impact memory. Although stress reactivity differs between us ...
Jun 14, 2024 · While generally highly adaptive, the effects of stress on memory, much like exaggerated bodily stress responses, can become maladaptive and contribute to the development of mental disorders. Stress is a well-established factor in various mental disorders, including posttraumatic stress disorder (PTSD) and anxiety disorders, in which maladaptive memory processes are prominent.
Oct 9, 2023 · Research has shown that one of the key elements of our acute stress response (a hormone called cortisol) can impair the part of the brain (the hippocampus) that is involved in encoding memories. Now, a new study shows that stress’ effect on memory is not quite that simple.
Abstract. Stress is a potent modulator of learning and memory processes. Although there have been a few attempts in the literature to explain the diversity of effects (including facilitating, impairing, and lack of effects) described for the impact of stress on memory function according to single classification criterion, they have proved insufficient to explain the whole complexity of effects.
While stress around the time of learning enhances memory, stress (or cortisol administration of 25 mg) long before learning or in a distinctly different context does not promote new learning 43 and can even hinder successful encoding of new information. 21 For example, while stress directly before learning enhanced later recognition memory, memory was impaired if stress was experienced 30 min ...
Feb 9, 2023 · The fact that stress interferes with LTP in the hippocampus is significant because it offered a post-hoc neurophysiological marker to compare how different types of stress affect memory (i.e ...

Mar 21, 2022 · While being generally highly adaptive, overly strong or aberrant stress effects on cognitive processing, particularly on memory formation, can become maladaptive and contribute to stress-related mental disorders such as posttraumatic stress disorder (PTSD) or anxiety disorders (de Quervain et al., 2017; Pitman et al., 2012).
