  • Title: The hypothalamic-pituitary-thyroid axis in agoraphobia, panic disorder, major depression and normal controls.
    Author: Hofmann PJ, Nutzinger DO, Kotter MR, Herzog G.
    Journal: J Affect Disord; 2001 Sep; 66(1):75-7. PubMed ID: 11532535.
    Abstract:
    BACKGROUND: Much interest has been drawn to the investigation of the hypothalamic-pituitary-thyroid (HPT)-axis in patients suffering from depression or panic disorder. However, there is no data concerning agoraphobia. METHODS: Patients with panic disorder, agoraphobia, major depression were compared to normal controls (total n=88) in respect to HPT axis, obtaining basal TSH and administering a TRH test. RESULTS: Normal controls and agoraphobics showed significantly higher Delta(max) TSH than depressives and panic patients. There were no differences between agoraphobics and normal controls. CONCLUSIONS: Agoraphobia, unlike depression or panic disorder, seems to be less biologically determined in respect to the HPT-axis.
