Frontiers in the use of biomarkers of health in research on stress and aging

Jennifer R Piazza et al. J Gerontol B Psychol Sci Soc Sci. 2010 Sep.

Abstract

Assessment of biomarkers that reflect objective indicators of physiological processes has become increasingly popular in psychological research on stress and aging. The current article reviews biomarkers of the neuroendocrine and immune systems, including issues related to measurement and normative age-related changes. We also discuss how exposure to stressors can provoke changes in these biomarkers and propose that stressful experiences may accelerate age-related declines in these systems. We recommend that future research examining physical health and aging incorporate dynamic and multivariate methods for assessing links between stressors and biomarkers.

A simplified representation of the components of the autonomic nervous system and the hypothalamic–pituitary–adrenal axis stress system. CRH = corticotrophin-releasing hormone, ACTH = adrenocorticotropin hormone, EPI = epinephrine, NE = norepinephrine, AVP = arginine vasopressin. Solid lines represent direct or indirect stimulatory pathways. Dashed lines represent direct or indirect inhibitory pathways. (Adapted from Klein and Corwin, 2002.)
