Objective: Heart rate variability, a quantitative measure of mainly parasympathetic activity,
has been applied in evaluating many types of psychiatric and neurological disorders …

Background: Decreased heart rate variability (HRV) indexes indicate low vagal activity and
may be associated with development of dementia. The neurodegenerative process is …

Neurodegenerative diseases, which frequently present with neuropsychiatric symptoms
related to prefrontal cortical dysfunction, can alter the integrity of the neural networks …

Objective There is strong evidence for a bi-directional relationship between heart-health and
depression in later life, but the physiological mechanisms underlying this relationship …

Aims Patients with anxiety disorders (AD) have been found to have lower heart rate
variability (HRV) than healthy individuals in some studies, but this was inconsistent …

Heart rate variability (HRV) is a sensitive method for the assessment of autonomic function
and requires little cooperation from the subject, making it suitable for use in dementia …

Objective To determine whether older primary care patients with a Major Depressive
Disorder (MDD) have lower heart rate variability (HRV) compared to non‐depressed …

Heart rate variability (HRV) reflects beat-to-beat variability in the heart rate due to the
dynamic interplay of the sympathetic and parasympathetic nervous systems. HRV is …

Objective Age is associated with changes in autonomic nervous system activity. These
changes are assessed using heart rate variability (HRV) indicators; however, the effect of …

Introduction: Resting heart rate (RHR) predicts future risk for cardiovascular disease (CVD).
However, longitudinal studies investigating the relationship of RHR with cognitive decline …
