Abstract

Neurobiological processes are highlighted in animal and theoretical models of the development of depression, but there is mixed empirical evidence about associations between stress physiology and depressive symptoms. Adolescence has been highlighted as a period during which coordination across physiological stress response systems may be particularly important. However, most studies have focused on depressive symptoms and physiological reactivity in isolated systems. The goal of this study was to examine associations of hypothalamic-pituitary-adrenal (HPA) axis and autonomic nervous system (ANS; i.e., sympathetic and parasympathetic nervous system [SNS and PNS, respectively]) reactivity with depressive systems, as well as the interrelatedness of reactivity across systems. Participants were adolescents (n = 153, 10-17 years) from diverse backgrounds, recruited from the community. Adolescents experienced a stressor, during which cortisol (HPA axis), skin conductance level (SCL; SNS), and respiratory sinus arrhythmia (RSA; PNS) were measured; youth also reported depressive symptoms. Some youth (n = 60) reported depressive symptoms again 1 year later as part of another study. Results from latent growth analysis embedded in a struct...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
