Pj. Hofmann et al., The hypothalamic-pituitary-thyroid axis in agoraphobia, panic disorder, major depression and normal controls, J AFFECT D, 66(1), 2001, pp. 75-77
Background: Much interest has been drawn to the investigation of the hypoth
alamic-pituitary-thyroid (HPT)-axis in patients suffering from depression o
r 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 pat
ients. 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. (C) 2001 Elsevier
