In this study we investigated heart rate variability (HRV), a proxy for vagal activity, as a biological marker for disease severity in patients with schizophrenia (SZ) and bipolar disorder (BD). Heart rate variability (HRV) was calculated in 35 patients with SZ and 52 patients with BD, as well as in 146 healthy controls Results suggest that disease severity is associated with autonomic dysfunction.

Understanding the role of the autonomic nervous system, as measured by heart rate variability, in mental and somatic health

Contact with nature is widely considered to ameliorate psychological stress, but the empirical support for a causal link is limited. We conducted a systematic review to synthesize and critically assess the evidence. Six electronic databases were …

Heart rate variability (HRV) is a widely used measure that reflects autonomic (parasympathetic) control of the heart. HRV has been linked with attentional performance, but it is unclear to what extent resting HRV is associated with both attention and …

Reduced cardiac autonomic function is associated with increased risk of cardiovascular disease (CVD), with heart rate variability (HRV) providing an accessible index of cardiac autonomic function. HRV may provide a candidate physiological mechanism …

Understanding the association between autonomic nervous system [ANS] function and brain morphology across the lifespan provides important insights into neurovisceral mechanisms underlying health and disease. Resting state ANS activity, indexed by …

Heart rate variability (HRV) is a common measure of the autonomic modulation of the heart. To ensure accuracy, various external factors known to affect HRV such as medication use and concurrent illnesses are frequently controlled during measurement. …

Research on heart rate variability (HRV) has been conducted for more than four decades, and the increasing interest in this complex psychophysiological

The autonomic nervous system (ANS) plays an important role in attention and self-regulation by modulating physiological arousal to meet environmental demands. Core symptoms of ADHD such as inattention and behavioral disinhibition may be related to …
