Associations Between and Changes in Hippocampal Volume and the Cortisol Response Over Time: The Role of Childhood Maltreatment and Depression
Stress-related brain mechanisms, specifically HPA axis dysregulation and reductions in hippocampal volume, have long been associated with the pathology of major depressive disorder, especially within the context of a history of childhood maltreatment. However, investigations that examine the …

An examination of psychological stress and its effects on the mitochondrial DNA
Background: With improvements in cellular stress measurement, current findings firmly implicate mitochondrial activity in cell stress reactions. Recent studies have highlighted the effects of psychological stress on mitochondria in terms of oxidative deterioration and crisis signalling. However, …

The current study evaluated whether trait attentional control mediated the relationship between trait worry and cortisol stress response after a psychosocial stressor. Participants (N=95) completed several …

Exploring the Pathophysiology of Chronic Depression: The Interplay between Depression, Cortisol Responses, and Personality
… Study 1 examined cortisol responses to the Trier Social Stress Test (TSST) in CMDD participants (n=29) as compared to healthy controls (n=28). It was hypothesized that cortisol responses would be greater in the CMDD population. Results indicated that females with CMDD had increased cortisol …

The impact of acute psychological stress on spatial cognition
… study was to investigate the effects of psychosocial stress (and consequent cortisol increase) on spatial cognition and verbal memory in men and women. One group of 33 participants (16 males and 17 females) were exposed to the Trier Social Stress Test (TSST; Kirschbaum, Pirke, & Hellhammer, …

Impact of the Serotonin-Transporter-Polymorphism (5-HTTLPR) and Stressful Life Events on the Stress Response in Humans
… 5-HTTLPR seems to impact on the role of stressful life events (SLEs) in the development of depression. An elevated risk of depression and suicidal behaviors has been found in carriers of at least one low expressing S allele who had experienced SLEs, suggesting a gene x environment …
