Purpose of review Stress exacerbates mental illnesses such as depression but also appears to increase risk of dementia, suggesting a common mechanism for development of stress-induced affective and cognitive impairment. The purpose of this review is to address the question of whether anxiety ‘damages’ the brain, and to identify potential mechanisms for the link between stress and neuropsychiatric illness. Recent findings Anxiety disorders are associated with alterations in fear neurocircuitry… 
Chronic Stress Leads to Anxiety and Depression
Studies have found a link between chronic stress and anxiety disorders as well as major depressive disorder. This article reviews literature based on that keeping in view the physiology of stress and
Acute stress induces long-lasting alterations in the dopaminergic system of female mice
TLDR
The results reveal the impact stress exerts on females and show that neural and behavioral changes induced by acute stress exposure are still present months later.
Executive Functions in panic disorder: A mini-review.
Negative Emotional Verbal Memory Biases in Mild Cognitive Impairment and Late-Onset Depression.
Aberrant brain grey matter volume patterns differ among Chinese Han drug-naïve depression patients with acute and chronic stress
TLDR
The findings provide important information for the use of appropriate treatment methods to address acute stress and alleviate chronic stress in patients with depression, and such treatments can delay the deterioration of the affected brain regions and improve remission rates.
Exploring Associations Between a Biological Marker of Chronic Stress and Reported Depression and Anxiety in People With Aphasia.
TLDR
Cortisol level was not associated with depression and anxiety across this sample of people with aphasia, but a post hoc analysis showed a significant, positive correlation between a subset of participants with moderate and higher levels of depression and elevated cortisol level.
Cerebrovascular dysfunction with stress and depression
TLDR
The stress-induced alterations in neurovascular coupling with specific attention to cerebrovascular regulation (endothelial dependent and independent vasomotor function, microvessel density) are discussed and the pathophysiological consequences of cerebral microvascular dysfunction with stress and depression are explored.

Hippocampal neurogenesis: Opposing effects of stress and antidepressant treatment
TLDR
The literature that has lead to a neurogenic hypothesis of depression and antidepressant action, as well as the molecular and cellular mechanisms that underlie the regulation of adult neurogenesis by stress and antidepressant treatment are discussed.
Glucocorticoids and hippocampal atrophy in neuropsychiatric disorders.
  • R. Sapolsky
  • Psychology, Biology
    Archives of general psychiatry
  • 2000
TLDR
This review examines the evidence for hippocampal atrophy in Cushing syndrome, which is characterized by a pathologic oversecretion of glucocorticoids; (2) episodes of repeated and severe major depression; (3) posttraumatic stress disorder and what cellular mechanisms underlie the overall decreases in hippocampal volume.
Chronic Stress-induced Hippocampal Vulnerability: The Glucocorticoid Vulnerability Hypothesis
  • C. Conrad
  • Biology, Psychology

  • 2008
TLDR
The finding that the hippocampus can recover from dendritic retraction without any noticeable cell loss is of particular interest, and it is proposed that a chronic stress history, which includes repeated elevation of glucocorticoids, may make the hippocampus vulnerable to potential injury.
Psychosocial stress reversibly disrupts prefrontal processing and attentional control
TLDR
It is shown that psychosocial stress induces long-lasting but reversible impairments in behavioral and functional magnetic resonance imaging (fMRI) measures of PFC function in humans, and one mechanism by which disrupted plasticity may contribute to cognitive impairments characteristic of stress-related neuropsychiatric conditions in susceptible individuals is suggested.
Role of the Amygdala in the Coordination of Behavioral, Neuroendocrine, and Prefrontal Cortical Monoamine Responses to Psychological Stress in the Rat
TLDR
Evidence is provided of amygdalar control of stress-induced metabolic activation of the monoaminergic systems in the m-PFC, as well as amygdAlar integration of behavioral and neuroendocrine components of the rat stress response.
Functional neuroimaging of anxiety: a meta-analysis of emotional processing in PTSD, social anxiety disorder, and specific phobia.
TLDR
A meta-analysis of functional magnetic resonance imaging and positron emission tomography studies of posttraumatic stress disorder, social anxiety disorder, specific phobia, and fear conditioning in healthy individuals provided neuroimaging evidence for common brain mechanisms in anxiety disorders and normal fear.
