Autonomic cardiac dysfunction is a common complication in patients with anorexia nervosa (AN). Despite its high prevalence, physicians often overlook this clinical condition, and little research has been dedicated so far. To probe the functional role of the neurocircuitry underpinning the poorly understood autonomic cardiac dysfunction, we examined dynamic functional differences in the central autonomic network (CAN) between 21 acute AN individuals and 24 age, sex and heart rate-matched healthy controls (HC).

Objective: Recent studies suggest that lower resting heart rate variability (HRV) is associated with elevated vulnerability to depressive rumination. In this study, we tested whether increases in HRV after HRV-biofeedback training are accompanied by reductions in rumination levels.

Materials And Methods: Sixteen patients suffering from depression completed a 6-week HRV-biofeedback training and fourteen patients completed a control condition in which there was no intervention (waitlist).

Structural brain abnormalities are a consistent finding in anorexia nervosa (AN) and proposed as a state biomarker of the disorder. Yet little is known about how regional structural changes affect intrinsic resting-state functional brain connectivity (rsFC). Using a cross-sectional, multimodal imaging approach, we investigated the association between regional cortical thickness abnormalities and rsFC in AN.
