Physical and Emotional Abuse Shows Indirect Effects on Cortisol Reactivity

June 6, 2019

Childhood abuse predicts affective symptoms via HPA reactivity during mother-infant stress Author: Kern S & Laurent HK. (2019), Psychoneuroendocrinology. ABSTRACT: Despite extensive literature positing the hypothalamic-pituitary-adrenal (HPA) axis as a mechanism in the association between early childhood maltreatment and later adult psychopathology, empirical support for this full pathway is lacking. We tested indirect effects of […]

Prefrontal Cortex and Amygdala Activity Lead to Differing Individual Psychosocial Stress Emotional Responses

April 26, 2019

Amygdala and prefrontal cortex activity varies with individual differences in the emotional response to psychosocial stress. Author: Orem TR, et al. (2019), Behav Neurosci. ABSTRACT Stress elicits a variety of psychophysiological responses that show large interindividual variability. Determining the neural mechanisms that mediate individual differences in the emotional response to stress would provide new insight […]

Early Head Start Services Improve Infants’ Cortisol Regulation and Recovery

March 22, 2019

Improving Infants’ Stress-Induced Cortisol Regulation through Attachment-Based Intervention: A Randomized Controlled Trial Author: Berlin LJ, et al. (2019), Psychoneuroendocrinology. ABSTRACT Attachment-based parenting interventions have shown positive effects on early cortisol regulation, a key biomarker. Evaluations to date have focused on diurnal cortisol production in high-risk infants. It is important to understand whether attachment-based intervention may […]

Salivary Cortisol and DHEA are Inversely Correlated with Early Postnatal Growth and Blood Pressure in Extremely Preterm Children

February 5, 2019

Adrenal function links to early postnatal growth and blood pressure at age 6 in children born extremely preterm Author: Watterberg KL, et al. (2018), Pediatric Research. BACKGROUND: Low birth weight in term-born individuals correlates with adverse cardiometabolic outcomes; excess glucocorticoid exposure has been linked to these relationships. We hypothesized that cortisol and adrenal androgens would correlate […]

Low Salivary Alpha-Amylase Awakening Response Associated with Reduced Professional Efficacy

January 10, 2019

Reduced professional efficacy is associated with a blunted salivary alpha-amylase awakening response. Author: Landolt K, et al. (2018), Physiol Behav. ABSTRACT: The job demands-resources model (JD-R) has shown an ability to predict worker engagement and exhaustion, yet to our knowledge, research has not been conducted that assesses the JD-R model with physiological indicators of chronic stress […]
