Key result
Reduction in heart rate variability is a main manifestation in major depressive disorder, schizophrenia, and posttraumatic stress disorder, and is closely linked to changes in quantitative electroencephalography and cognitive performance.
Why the study?
Abnormal heart rate variability has been reported in mental disorders, motivating an overview of heart rate variability and its link to cognitive function and brain activity in psychiatric illness.
How is heart rate variability characterized in patients with psychiatric illnesses (MDD, schizophrenia, PTSD) and how does it interact with qEEG and cognitive function?
Population

HRV reduction may aid psychiatric assessment; leaves open whether integrated HRV-qEEG monitoring improves outcomes in MDD, schizophrenia, or PTSD.
How is heart rate variability characterized in patients with psychiatric illnesses (MDD, schizophrenia, PTSD) and how does it interact with qEEG and cognitive function?
This review highlights that reduced heart rate variability is a key manifestation in major psychiatric disorders and is closely linked to cognitive performance and qEEG changes.
Jung et al. (2019) conducted a review in Psychiatric Illness (Major Depressive Disorder, Schizophrenia, Posttraumatic Stress Disorder). Heart rate variability (HRV) assessment vs. Healthy controls was evaluated. Reduction in heart rate variability is a main manifestation in major depressive disorder, schizophrenia, and posttraumatic stress disorder, and is closely linked to changes in quantitative electroencephalography and cognitive performance.
