Reduction of depressive symptoms during inpatient treatment is not associated with changes in heart rate variability
2021
Vagally mediated heart rate variability (HRV) is a psychophysiological indicator of mental and physical health. Limited research suggests there is reduced vagal activity and resulting lower HRV in patients with Major Depressive Disorder (MDD); however little is actually known about the association between HRV and symptoms of depression and whether the association mirrors symptom improvement following psychotherapy. The aim of this study was to investigate the association between antidepressant therapy, symptom change and HRV in 50 inpatients (68% females; 17–68 years) with a diagnosis of MDD. Severity of depressive symptoms was assessed by self-report (Beck Depression Inventory II) and the …
The cortisol awakening response at admission to hospital predicts depression severity after discharge in MDD patients.
2019
Major Depressive Disorder (MDD) is associated with hypothalamic-pituitary-adrenal axis (HPA) dysregulation and altered cortisol awakening response (CAR), a non-invasive biomarker for HPA axis reactivity. We theorized that the CAR resembles the accumulated effects of depression over time, and may therefore predict depressive symptom severity once patients return home following inpatient treatment. Two studies are reported. In Study 1 (n = 101; 57% female), the CAR was measured at intake and self-ratings of depression severity was assessed six weeks following discharge. Study 2 (n = 127; 58% female) was a replication and extension of Study 1 where a follow-up assessment of self-rated depressi…
