Abstract:
The 2:1 female-to-male sex difference in the prevalence of panic disorder (PD) suggests that there is a sex-specific vulnerability involved in the etiology and/or maintenance of this disorder. The purpose of this paper is to present a new conceptual model, which emphasizes the interaction between a cognitive vulnerability for PD, anxiety sensitivity, and the effects of progesterone and its metabolite, allopregnanolone, on behavioral and physiological responses to stress during the premenstrual phase. This interaction is proposed to be a potential sex-specific pathway that may initiate and/or maintain panic and anxiety symptoms in women. This review paper presents preliminary evidence from both the human and animal literatures to support this new model. Specific topics reviewed include: psychopathology related to the menstrual cycle, anxiety sensitivity and its relationship to the menstrual cycle, PMS, and PMDD, anxiety-modulating effects of progesterone and its neuroactive metabolite, allopregnanolone, and how results from the neuroendocrine literature relate to psychopathology or symptoms associated with the menstrual cycle.

Panic Disorder
Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.
