Increased plasma norepinephrine concentration in psychotic depression
Open accessAbstract
OBJECTIVE: We previously found psychotic depression (PSDEP) to have positively correlating plasma norepinephrine (NE) and vasopressin (AVP) concentrations. Since central noradrenergic activity and plasma NE concentration are highly correlated, this suggests an increased noradrenergic activation of the hypothalamus-pituitary-adrenal axis. We hypothesize the increased release of NE in PSDEP to be an associated mechanism. METHODS: To test this hypothesis we analyzed the relation between plasma NE and PSDEP in a comparison with non-psychotically depressed patients. Potentially confounding variables were, among others, melancholia and two better validated subcategories in the field of melancholia and endogenous depression, three global dimensions of psychopathology - Emotional Dysregulation, Retardation and Anxiety - smoking habit, and different types of psychotropic and particularly antidepressant treatment. The data from nine patients with PSDEP and 69 patients with non-PSDEP were reanalysed. RESULTS: Analysis of covariance controlling for the effects of tricyclic antidepressant treatment (≥100 mg) and smoking habit showed that PSDEP had an increased concentration of plasma NE. The previously found correlation between plasma NE and AVP was still present after correcting for the effects of confounding variables. CONCLUSIONS: The results suggest an increased activity of the sympathetic nervous system in PSDEP that may act as a specific mechanism for increased vasopressinergic activation. This supports the view of PSDEP as a distinct subcategory of major depression.

Experiential avoidance has been associated with anxiety.
“Experiential avoidance seeks to control the way or frequency of aversive private experiences [37] and has been associated with anxiety [38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54].”
From The Effect of Anxiety and Nutritional Habits on the Body Distortion of Athletes. (2025) · cites this paper as [44]
The Results discuss anxiety as a dimension related to plasma norepinephrine in patients with depression, not its association with experiential avoidance. A Discussion passage mentions conditioned avoidance behaviour in animal models, which is not the same construct. Searches for “experiential avoidance associated with anxiety” and “experiential avoidance control aversive private experiences” found no passage addressing the claimed association; page numbers were not available in our copy.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
