It is known that mood disorders in women explicitly relates to estrogen production. Except for these findings phenomenon as Premenstrual Syndrome and Premenstrual Dysphoric Disorder, directly connected to menstrual cycle in women, is widely discussed. Premenstrual dysphoric disorder (PMDD) is a set of subjectively unpleasant mental and somatic symptoms. It appears in luteal phase of ovarian cyc...

BACKGROUND Despite an abundance of clinical research on premenstrual and menstrual symptoms, few epidemiological data provide estimates of the prevalence, incidence, co-morbidity, stability and correlates of premenstrual dysphoric disorder (PMDD) in the community. AIMS To describe the prevalence, incidence, 12 co-morbidity factors and correlates of threshold and subthreshold PMDD in a communi...

Premenstrual syndrome and premenstrual dysphoric disorder (PMDD) seem to form a severity continuum with no clear-cut boundary. However, since the American Psychiatric Association proposed the research criteria for PMDD in 1994, there has been no agreement about the symptomatic constellation that constitutes this syndrome. The objective of the present study was to establish the core latent struc...

The cause of premenstrual dysphoric disorder (PMDD) is largely unknown. It has been hypothesized that normal ovarian function triggers PMDD-related biochemical events within the brain and that serotonin plays an important role. In the present study, positron emission tomography (PET) and [carbonyl-(11)C]WAY-100635 were used to examine serotonin 5-HT(1A) receptors in a control group of women and...

Increasing evidence has suggested that the GABAergic neurotransmitter system is involved in the pathogenesis of premenstrual dysphoric disorder (PMDD). We used proton magnetic resonance spectroscopy ((1)H MRS) to investigate whether PMDD is associated with alterations in brain GABA levels. Levels of glutamate-glutamine (Glx) were also explored. Participants comprised 22 women with PMDD and 22 a...

BACKGROUND Premenstrual dysphoric disorder (PMDD) is a prevalent disorder in the spectrum of affective illness, and is associated with significant morbidity. The neurobiology of this underdiagnosed and undertreated illness is poorly understood. A functional magnetic resonance imaging (fMRI) probe of fronto-limbic function was used to advance understanding of PMDD pathophysiology. METHODS We a...
