Histories of major depression and premenstrual dysphoric disorder: Evidence for phenotypic differences

The role of the hypothalamic-pituitary-adrenal axis in depression across the female reproductive lifecycle: current knowledge and future directions

The aim of this narrative review is to consolidate knowledge on the role of the hypothalamic-pituitary-adrenal (HPA) axis in depression pathophysiology at different reproductive stages across the female lifespan. Despite growing evidence about the impact of gonadal hormones on mood disorders, no previous review has examined the interaction between such hormonal changes and the HPA axis within the context of depressive disorders in women. We will focus on HPA axis function in depressive disorders at different reproductive stages including the menstrual cycle (e.g., premenstrual dysphoric disorder [PMDD]), perinatally (e.g., postpartum depression), and in perimenopausal depression. Each of these reproductive stages is characterized by vast physiological changes and presents major neuroendocrine reorganization. The HPA axis is one of the main targets of such functional alterations, and with its key role in stress response, it is an etiological factor in vulnerable windows for depression across the female lifespan. We begin with an overview of the HPA axis and a brief summary of techniques for measuring HPA axis parameters. We then describe the hormonal milieu of each of these key reproductive stages, and integrate information about HPA axis function in depression across these reproductive stages, describing similarities and differences. The role of a history of stress and trauma exposure as a contributor to female depression in the context of HPA axis involvement across the reproductive stages is also presented. This review advances the pursuit of understanding common biological mechanisms across depressive disorders among women. Our overarching goal is to identify unmet needs in characterizing stress-related markers of depression in women in the context of hormonal changes across the lifespan, and to support future research in women's mental health as it pertains to pathophysiology, early diagnosis, and treatment targets.

Effects of cognitive emotion regulation strategies on mood and cortisol in daily life in women with premenstrual dysphoric disorder

BACKGROUND

The psychological risk factors of premenstrual dysphoric disorder (PMDD) are not fully understood, but initial evidence points to a potential role of unfavorable cognitive emotion regulation (ER-) strategies. Given the symptom cyclicity of PMDD, ambulatory assessment is ideally suited to capture psychological and physiological processes across the menstrual cycle. Our study examines habitual ER-strategies in women with PMDD and their predictive value for the course of mood and basal cortisol across the cycle in affected women.

METHODS

Women with and without PMDD (n = 61 each) were compared regarding habitual mindfulness, reappraisal, and repetitive negative thinking (RNT). Momentary affect and cortisol output were assessed over two consecutive days per cycle phase (menstrual, follicular, ovulatory, late luteal).

RESULTS

Women with PMDD reported lower mindfulness, less use of reappraisal and stronger RNT than controls (ps < 0.035). In women with PMDD, higher mindfulness and reappraisal and lower RNT predicted decreased negative and increased positive affect across the menstrual cycle (ps < 0.027). However, women using more favorable ER-strategies displayed stronger mood cyclicity, resulting in stronger mood deterioration in the late luteal phase, thereby resembling women with more unfavorable ER-strategies toward the end of the cycle. Lower mindfulness predicted lower cortisol in the menstrual phase.

CONCLUSIONS

Protective ER-strategies seem to be generally linked to better momentary mood in women with PMDD, but do not appear to protect affected women from premenstrual mood deterioration. Habitual mindfulness, in turn, seems to buffer blunted cortisol activity in women with PMDD, especially in the menstrual phase.

holistic view of management of polycystic ovarian syndrome

Polycystic ovary syndrome (PCOS) is one of the most prevalent disorders in women which influence their endocrine and metabolic functioning. It causes physical and psychological issues which are responsible for causing disturbances in daily life of women. Apart from genetics, stress, anxiety, obesity, and sedentary life style are among several factors that contribute to this disease. Hence, the treatment must target all these factors. Yoga, diet, exercises and therapies like mindfulness based cognitive therapy (MBCT) have significant effects on management of symptoms of PCOS. Assessment of the overall health of women can assist in the treatment programme and integral plans can be designed to deal with the problem. The purpose of this qualitative study is to assess different treatment outcomes which can help the women suffering from PCOS, health experts, and mental health workers in understanding, management and treatment of this disease from a holistic point of view. This could further enhance the well-being and overall living pattern of the women.

Menstrual attitude and social cognitive stress influence autonomic nervous system in women with premenstrual syndrome

The autonomic nervous system (ANS) is activated by stress and is closely related to the female menstrual cycle. Women with premenstrual syndrome (PMS) have an imbalanced ANS response in their premenstrual period. However, no studies have explored the reasons for the differences in ANS response among women. In this study, we investigated how the female menstrual attitude and acute social stress influence the ANS response in women with PMS. First, 277 women [24.35 ± 2.1] were selected to measure the mediating role of women's menstrual attitude between PMS severity and perceived ANS response. Second, participants' (50 women [23.23 ± 1.25] with and 46 women [22.92 ± 2.00] without PMS) heart rate (HR) and HR variability (HRV; reflecting the functioning of ANS) under social stress were measured during various menstrual cycle phases. The results indicated that menstrual attitude (bothersome and predictable) had mediating effects between the degree of PMS and perceived ANS response; when undergoing a high cognitive load (e.g. mental-arithmetic) task, the ANS of the PMS group demonstrated hypo-arousal and delayed recovery in the late luteal phase; Therefore, menstrual attitude could influence female perceived ANS response, which may be a risk factor for PMS. When women with PMS experience high-strength cognitive pressure in the premenstrual period, their ANS showed hypo-arousal and delayed recovery, which may be another risk factor for PMS.

Premenstrual dysphoric disorder and childhood maltreatment, adulthood stressful life events and depression among Lebanese university students: a structural equation modeling approach

BACKGROUND

Premenstrual Syndrome (PMS) is a cyclic sequence of physical and behavioral symptoms that arise in the second half of the menstrual cycle. The extreme type of PMS is Premenstrual Dysphoric Disorder (PMDD). The current study aims at examining 1) the effects of childhood maltreatment and current life's stressful events on PMDD, and 2) the mediating role of depression in these associations among Lebanese university female students.

METHODS

This cross-sectional study was conducted between February and March 2021 during the COVID-19 pandemic. Lebanese students were recruited using a snowball technique from all national universities in Lebanon via an auto-administrated online survey. Structural equation modeling was performed to examine the structural relationship between childhood maltreatment and life's stressful events, depression and PMDD.

RESULTS

Higher life's stressful events (Beta = 0.18; p < 0.001), physical (Beta = 0.19; p < 0.001), sexual (Beta = 0.18; p < 0.001) and psychological (Beta = 0.33; p < 0.001) abuse were significantly associated with higher depression. Moreover, higher sexual (Beta = 0.11; p = 0.021) and psychological (Beta = 0.11; p = 0.040) abuse and higher depression (Beta = 0.37; p < 0.001) were significantly associated with higher PMDD. The indirect relationships between psychological abuse/sexual abuse, depression and PMDD showed that depression mediated the association between both psychological (Beta = 0.22; p = 0.001) and sexual (Beta = 0.38; p = 0.004) abuse and PMDD.

CONCLUSION

This work presents a unique analysis using the structural equation model that enlightens the effect of childhood maltreatment, particularly sexual and psychological abuse on PMMD symptoms, with depression playing the role of a mediating factor. It would be interesting to test, in future studies, whether there are other mediating factors besides depression that could be indirect indicators of PMDD.

Patterns of premenstrual syndrome and depression symptoms in Chinese female university students: Results of a latent profile analysis

BACKGROUND

Premenstrual syndrome (PMS) and depression co-occur frequently; however, their relationship remains controversial. This study was conducted primarily to discern heterogeneous patterns of such co-occurring symptoms in Chinese female university students, using a latent profile analysis (LPA), a person-centered statistical approach.

METHODS

The PMS Scale and Beck Depression Inventory were used to examine self-reported PMS and depression symptoms in 701 Chinese female university students. LPA, multinomial logistical regression, and analyses of variance were adopted to investigate latent profiles and their validity.

RESULTS

The LPA results indicated that a four-class solution characterized by low symptoms (57.2%), predominantly PMS (11.3%), predominantly depression (23.7%), and combined PMS-depression (7.8%) patterns fitted the data best. Age, first menstrual experience, and personality factors were associated with differences in nonparallel profiles characteristic of menstrual attitude.

LIMITATIONS

Use of self-report measures can lead to response biases; the cross-sectional design at a single time point limits the examination of changes in symptom characteristics and members within the category over time; and the specific age group limits the generalizability of results.

CONCLUSION

These results confirm that PMS is independent from depression, rather than a variant of depression, and can be used to resolve the controversy regarding the relationship between PMS and depression. The current findings highlight the need for identifying women at high risk for PMS and depression, and promoting interventions individually tailored to their symptom presentations.

Response to sertraline is associated with reduction in anxiety-potentiated startle in premenstrual dysphoric disorder

RATIONALE

Women with premenstrual dysphoric disorder (PMDD) appear to have altered central nervous system sensitivity to neuroactive steroid hormones, manifesting as affective symptoms and heightened arousal in the luteal phase of the menstrual cycle. In particular, women with PMDD appear less sensitive to allopregnanolone, a positive allosteric GABA-A receptor (GABA-A-R) modulator.

OBJECTIVES

This study evaluated psychophysiologic reactivity in women with PMDD in the follicular and luteal phases of the menstrual cycle, utilizing anxiety-potentiated startle (APS), a potential translational marker of GABA-A-R sensitivity. The study also assessed APS response to low-dose sertraline treatment in women with PMDD.

METHODS

Participants' APS and fear-potentiated startle (FPS) were assessed in the follicular and luteal phases. Women with PMDD received 50 mg sertraline in the following luteal phase to examine impact on APS and FPS.

RESULTS

There were no significant differences between controls (n = 41) and PMDD participants (n = 36) in change from follicular to luteal phases in baseline startle, APS nor FPS. However, among participants who responded to sertraline, APS was higher in the untreated luteal phase than the follicular phase, but lower in the treated luteal phase than the follicular phase.

CONCLUSION

These data demonstrate elevated psychophysiologic arousal in the luteal phase among some women with PMDD, suggesting impaired ability to modulate arousal reactivity. Specifically, alterations in APS suggest potential GABA-A-R changes across the menstrual cycle and in response to sertraline among treatment responders.

Associations between sex hormones, sleep problems and depression: A systematic review

Sleep problems and depression are both common and have a high impact on quality of life. They are also strongly associated and commonly occur together. During the reproductive age, both sleep problems and depression are almost twice as common in women than men. Epidemiological studies show that women experience more sleep problems and depressive symptoms around times when sex hormones change, such as puberty and menopause, but it is unclear what effect sex hormones have on sleep problems and depression. This systematic review aims to summarize and evaluate studies that investigated the relationship between sex hormones, sleep and depression. Systematic search resulted in 2895 articles, of which 13 met inclusion criteria. Depressed patients showed worse sleep than controls, but no significant difference in endogenous hormone levels was found. Additionally, higher endogenous estrogen was associated with better sleep in controls, but associations between endogenous sex hormones and depressive symptoms were inconclusive. More research on the effect of sex hormones on sleep and depression is necessary.

Premenstrual syndrome is associated with altered cortisol awakening response

Previous studies have revealed stress-induced dysregulation of hypothalamic-pituitary-adrenal (HPA) axis in women with premenstrual syndrome (PMS). So far, however, the results about the relationship between HPA axis dysregulation and PMS are mixed. To this end, it is necessary to investigate the basal activity of the HPA axis in women with PMS instead of only assessing a certain stressor. Therefore, this study evaluated the relationship between the cortisol awakening response (CAR) and PMS. Thirty-two women with PMS (mean age 22.47 ± 2.20 years) and 36 healthy controls (mean age 22.28 ± 2.43 years) were included in this study. Saliva samples of our participants were collected successively at 0, 30, 45, and 60 min after awakening to assess CAR during each of two phases of the menstrual cycle (the mid-follicular phase and the late luteal phase). The results showed a significantly attenuated CAR in women with PMS compared with the healthy controls, especially at 45 and 60 min after awakening, regardless of the menstrual cycle phases. Furthermore, there was a significant negative correlation between PMS severity as measured by PMS scale and AUCi (i.e. the Area Under the Curve with respect to increase) in the mid-follicular phase. Our findings suggested that an attenuated CAR activity profile may be an important risk factor for the development of PMS.

Cardiovascular Autonomic Profile in Women With Premenstrual Syndrome

Introduction: The premenstrual syndrome (PMS) is a constellation of somatic and psychogenic symptoms that appear during late luteal (LL) phase of the menstrual cycle. Since many symptoms could be related to the autonomic nervous system, we hypothesized that the sympathetic nervous system is perturbed in PMS.

Methods: The cardiovascular autonomic profile of nine women with PMS (30.4 ± 2.5 years) were compared to that of nine healthy controls (30 ± 2.5 years) during their early follicular (EF) and LL phases of the menstrual cycle. Plasma norepinephrine (NE) concentrations, power spectral analysis of heart rate and systolic blood pressure (BP), and baroreflex sensitivity (BRS) were assessed during recumbency and a head-up tilt (HUT). Cardiovascular responsiveness to α1- and β-adrenoreceptor agonists (phenylephrine and isoproterenol, respectively) were also assessed.

Results: In the LL phase, the plasma NE concentrations in women with PMS during recumbency and a HUT were lower than those in women without PMS [180 ± 30 vs. 320 ± 50 pg/ml; p = 0.04 (recumbent), and 480 ± 70 vs. 940 ± 180 pg/ml: p = 0.02 (HUT)]. In the LL phase, the dose of phenylephrine required to increase systolic BP by 15 mmHg in women with PMS was significantly greater than that in women without PMS (202 ± 30 μg vs. 138 ± 20 μg; p = 0.02). Sympathetic and vagal cardiac control indices were comparable in the two groups in the menstrual phases. In women with PMS, the value of LF_SBP in the LL phase was lower than that in the EF phase (0.98 ± 0.2 vs. 1.77 ± 0.4 mmHg², p = 0.04). The increase in LF_SBP in women with PMS in the LL phase during HUT was greater than that in the controls, 5.2 ± 0.9 vs. 3.1 ± 0.5 mmHg², p = 0.045, and this increase was associated with a significant decrease in BRS.

Conclusion: In women with PMS without psychogenic symptoms, the sympathetic control of their circulation is not dominant during the LL phase of their menstrual cycle.

The Effects of Sertraline in Controlling Refractory Hypertension in Women with Premenstrual Syndrome

Objective: The aim of this study was to evaluate the effect of Premenstrual Syndrome (PMS) treatment with selective serotonin reuptake inhibitor (SSRI) on treatment response of refractory hypertension of the patients. Method: This was a triple-blind randomized clinical trial conducted on female patients suffering from refractory hypertension and PMS at the same time. We obtained informed consent from 40 patients who had inclusion criteria and selected 20 patients for the intervention (sertraline 50 mg daily) and 20 for the control groups. The study period was five weeks. The mean of systolic and diastolic blood pressure before and after intervention was measured separately for each individual in each group and the mean of blood pressure of the members of the two groups were compared with each other. Results: The mean age of the participants was 43.60 ± 4.57. In this study, systolic and diastolic blood pressure of both groups reduced after intervention. The mean of systolic blood pressure was reduced by 40.86 mmHg in the intervention group and this reduction was 16 mm Hg in control group after intervention (P<0.001). Comparing this reduction between the two groups, we found that reduction rate in systolic blood pressure of the two groups did not have a significant statistical difference before and after the intervention (P = 0.11). Mean of diastolic blood pressure also showed reduction of 9.17 mm Hg and that of control group showed 6.7-mmHg reduction. Reduction rate of diastolic blood pressure in the intervention group had a statistically significant difference with that of the control group (P<0.017).‎‎ Conclusion: Administration of sertraline is more effective in controlling diastolic blood pressure in women suffering from refractory hypertension and comorbid PMS.

Is Pain Perception Altered in People With Depression? A Systematic Review and Meta-Analysis of Experimental Pain Research

Although clinical studies suggest depressed patients may be more vulnerable to pain, experimental research is equivocal. This meta-analysis aimed to clarify whether depression is associated with altered pain perception in response to noxious stimulation and to identify factors that might influence this association. A search of major electronic databases was conducted to identify experimental studies investigating pain response in depressed participants versus healthy control participants using established pain outcome measures. Random effects meta-analysis of standardized mean differences was conducted on data from 32 studies (N = 1,317). For high-intensity noxious stimulation, overall pain tolerance was similar across depressed and control groups (Hedges g = .09, P = .71, studies = 10). For low-intensity stimulation, a small, but statistically significant higher mean sensory threshold (g = .35, P = .01, studies = 9) and pain threshold (g = .32, P = .02, studies = 25) was observed in depressed participants, suggesting diminished pain. However, considerable heterogeneity in the direction and magnitude of effects was observed, indicating a likely condition-specific effect of depression on pain. Subgroup analysis found that pain threshold/tolerance was increased in depression for exteroceptive (cutaneous) stimulation but decreased for interoceptive (ischemic) stimulation, but that substantial heterogeneity remained. Overall, results provide some support for altered pain processing in depression, but suggest this link is dependent upon modality and additional, unidentified factors.

PERSPECTIVE

This meta-analysis of experimental studies suggests potential effects of depression on pain perception are variable and likely to depend upon multiple factors. The contrasting pattern for ischemic versus other noxious stimuli suggests that stimulus modality is a key factor, which could help explain discrepancies across clinical and experimental findings.

A path analysis of stress and premenstrual symptoms in Korean international and Korean domestic students

AIMS

To identify the relationships between perceived stress, acculturative stress and premenstrual symptoms, among other associated factors (e.g. depressive symptoms, coping self-efficacy, perceived social support) of premenstrual symptoms suggested in the literature by testing the conceptual framework of the 'Stress and Premenstrual Experience Model: Women in Cultural Transition'.

BACKGROUND

Level of perceived stress has been cited as a major influencing factor for women's premenstrual symptoms; however, how these two elements are related, including possible mediators and moderators, remains unclear.

DESIGN

A longitudinal causal-comparative web-based study design.

METHODS

Data collection occurred between November, 2014 - February, 2015. The convenience sampling method was used to recruit 98 Korean international students and 89 Korean domestic students. Weekly surveys were conducted for 10 weeks to capture women's levels of perceived stress, acculturative stress and premenstrual symptoms from two menstrual cycles. The survey data collected during the premenstrual phase was analysed using path analyses.

RESULTS/FINDINGS

The hypothesized pathways based on the conceptual model were partially supported in the study. Depressive symptoms were a partial mediator between perceived stress and premenstrual symptoms and between acculturative stress and symptoms in Korean international students. The perceived social support was a moderator between perceived stress and premenstrual symptoms in Korean domestic students.

CONCLUSION

This study proposes a revised conceptual model that will contribute to the understanding of stress and premenstrual symptom severity in women in the acculturation process and concludes with suggestions and implications for future nursing practice and research.

A lack of consistent evidence for cortisol dysregulation in premenstrual syndrome/premenstrual dysphoric disorder

Although decades of research has examined the association between cortisol regulation and premenstrual syndrome/premenstrual dysphoric disorder (PMS/PMDD), no review exists to provide a general set of conclusions from the extant research. In the present review we summarize and interpret research that has tested for associations between PMS/PMDD and cortisol levels and reactivity (n=38 original research articles). Three types of studies are examined: correlational studies, environmental-challenge studies, and pharmacological-challenge studies. Overall, there was very little evidence that women with and without PMS/PMDD demonstrate systematic and predictable mean-level differences in cortisol, or differences in cortisol response/reactivity to challenges. Methodological differences in sample size, the types of symptoms used for diagnosis (physical and psychological vs. only affective), or the type of cortisol measure used (serum vs. salivary), did not account for differences between studies that did and did not find significant effects. Caution is recommended before accepting the conclusion of null effects, and recommendations are made that more rigorous research be conducted, considering symptom-specificity, within-person analyses, and multiple parameters of cortisol regulation, before final conclusions are drawn.

Endogenous inhibition of pain and spinal nociception in women with premenstrual dysphoric disorder

Purpose

Premenstrual dysphoric disorder (PMDD) is characterized by severe affective and physical symptoms, such as increased pain, during the late-luteal phase of the menstrual cycle. The mechanisms underlying hyperalgesia in women with PMDD have yet to be identified, and supraspinal pain modulation has yet to be examined in this population. The present study assessed endogenous pain inhibitory processing by examining conditioned pain modulation (CPM, a painful conditioning stimulus inhibiting pain evoked by a test stimulus at a distal body site) of pain and the nociceptive flexion reflex (NFR, a spinally-mediated withdrawal reflex) during the mid-follicular, ovulatory, and late-luteal phases of the menstrual cycle.

Methods

Participants were regularly-cycling women (14 without PMDD; 14 with PMDD). CPM was assessed by delivering electrocutaneous test stimuli to the sural nerve before, during, and after a painful conditioning ischemia task. Participants rated their pain to electrocutaneous stimuli, and NFR magnitudes were measured. A linear mixed model analysis was used to assess the influence of group and menstrual phase on CPM.

Results

Compared with controls, women with PMDD experienced greater pain during the late-luteal phase and enhanced spinal nociception during the ovulation phase, both of which were independent of CPM. Both groups showed CPM inhibition of pain that did not differ by menstrual phase. Only women with PMDD evidenced CPM inhibition of NFR.

Conclusion

Endogenous modulation of pain and spinal nociception is not disrupted in women with PMDD. Additionally, greater NFR magnitudes during ovulation in PMDD may be due to tonically-engaged descending mechanisms that facilitate spinal nociception, leading to enhanced pain during the premenstrual phase.

Documenting stress in caregivers of transplantation patients: initial evidence of HPA dysregulation

There is growing evidence linking caregiver stress with an increased risk for morbidity and mortality. While the emotional and practical burden experienced by caregivers is well established, the physiological changes that may affect the caregiver's health are less understood. This study sought to compare self-reported stress, anxiety and depression along with neuroendocrine and immune markers of stress among adult caregivers of allogeneic hematopoietic stem cell transplantation patients during the acute transplant recovery period to matched non-caregivers controls. Biomarkers and self-reported data were collected at three points during the patient's HSCT: (1) before transplant, (2) after initial transplantation discharge (±7 days) and (3) 6 weeks after initial transplantation discharge. Mixed linear modeling was used to examine differences by group and time. Twenty-one caregivers and 20 controls completed all study procedures. The majority of caregivers were female (57% or 57.1%) and married (95.2%), with a mean age of 52 ± 11.4 years. Caregiver perceived stress, anxiety and depression scores were significantly higher than controls (p < 0.001) with effect sizes (ES) ranging from 1.37 to 1.80 and they did not change over time (p > 0.05) for either group. Caregivers had significantly lower serum cortisol levels than controls at both discharge (p = 0.013; ES = 0.81) and 6 weeks after discharge (p = 0.028; ES = 0.72) but exhibited no significant relationship between self-reported stress and serum cortisol. In addition, caregivers showed a significant inverse relationship between stress and epinephrine levels (r(s)=-0.654, p = 0.021). These findings support the evidence of the caregiving experience being stressful. The counter-intuitive relationship between cortisol and epinephrine might suggest dysregulation of the HPA axis and central nervous system but additional research on the physiological impact of caregiving is warranted.

The Effects of Mindfulness-Based Cognitive Therapy on Depression and Anxiety in Women with Premenstrual Syndrome

Objective. Little research has been done regarding the role of psychotherapy in the treatment of Premenstrual Syndrome (PMS). The aim of this study was to examine the effect of mindfulness-based cognitive therapy (MBCT) on the PMS symptoms and depression and anxiety symptoms in women with PMS. Design. In a randomized controlled trial, a total of 60 students at Mazandaran University with mild to moderate PMS who had depressive symptoms (Beck depression scores 16-47) were randomly allocated to either an experimental (n = 30) or a control (n = 30) group. The experimental group received MBCT in eight group sessions (120 min each) over 8 weeks. The control group received no intervention. All participants completed the Premenstrual Assessment Scale (PAS), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI) at the beginning and the end of the study. Repeated-measure ANOVA was used to analyze the data. Results. At the end of study, the experimental and control groups showed the following scores, respectively (mean ± SD): depression, 15.73 ± 6.99 and 25.36 ± 7.14; anxiety, 16.96 ± 7.78 and 26.60 ± 9.38; and total PAS, 42.86 ± 8.02 and 58.93 ± 8.47. MBCT improved depression and anxiety symptoms and total PAS score. Conclusion. MBCT intervention is acceptable and potentially beneficial in women with PMS symptoms. Psychotherapy should be considered as a treatment option for mild to moderate PMS in women with depressive symptoms.

Serum brain-derived neurotrophic factor differences between the luteal and follicular phases in premenstrual dysphoric disorder

OBJECTIVE

We hypothesized that comparison of the serum brain-derived neurotrophic factor (BDNF) levels between women with premenstrual dysphoric disorder (PMDD) and women without PMDD in the luteal and follicular phases of their menstrual cycles would reflect the altered neuromodulator responses that compensate the underlying pathogenesis in PMDD.

METHOD

Twenty-nine participants without PMDD and 20 with PMDD were enrolled in the study. The serum BDNF, estrogen and progesterone levels were assessed at the follicular and luteal phases in their two consecutive menstrual cycles.

RESULTS

Participants with PMDD had significantly higher luteal serum BDNF levels than the control subjects. The serum BDNF levels were significantly higher in the luteal phase than in the follicular phase in women with PMDD. The difference in the serum BDNF levels between the luteal and follicular phases were significantly higher in the PMDD patients than in the control.

CONCLUSIONS

The higher serum BDNF levels in the luteal phase in the PMDD patients may reflect compensatory process that results in subsequent improvement of the PMDD-associated depressive symptoms in the follicular phase. The higher difference in the serum BDNF levels between the phases in PMDD patients may reflect an altered neuromodulator response.

Lack of association of DRD3 and CNR1 polymorphisms with premenstrual dysphoric disorders

BACKGROUND

Premenstrual dysphoric disorder (PMDD) is a mood disorder characterized with physical and affective symptoms during the luteal phase of susceptible women.

OBJECTIVE

The aim of this study was to investigate the association of Dopamine D3 receptor (DRD3) polymorphism, and Cannabinoid receptor Type 1 (CNR1) polymorphism with PMDD.

MATERIALS AND METHODS

Fifty one participants with documented PMDD according to the DSM IV criteria and 51 healthy controls were included in this cross sectional study. Symptom severity was measured with daily self-rating, monthly premenstrual assessment forms and psychiatric interviews. The genotyping of DRD3 receptor and Cannabinoid type 1 receptors were performed using Taqmanfluorogenic assay method.

RESULTS

Distribution of DRD3 and CNR1 polymorphism was not different between patients and controls.

CONCLUSION

These findings do not support a major role of DRD3, and CNR1 polymorphisms in contributing to susceptibility to premenstrual dysphoric disorder.

Premenstrual syndrome is associated with blunted cortisol reactivity to the TSST

This study assessed the effects of premenstrual syndrome (PMS) and menstrual phases on the hypothalamic-pituitary-adrenal (HPA) axis, sympathetic nervous system axis and psychological responses to the Trier Social Stress Test (TSST). Thirty-six PMS women (mean age 21.69 ± 2.16 years) and 36 control women (mean age 22.03 ± 2.48 years) participated in the TSST task, either in the follicular phase or in the late luteal phase (each group N = 18). Saliva samples, heart rate and subjective stress levels were collected for seven time points throughout the test (10, 20, 30, 40, 55, 70 and 100 min). The results indicated that in comparison with control women, PMS women displayed blunted cortisol stress responses to the TSST irrespective of the menstrual phases, as indexed by the cortisol levels across time, area under the curve with respect to ground (AUCg) and peak change scores of cortisol. The results also demonstrated that the measurements indexed by cortisol levels across time, AUCg and peak change scores of heart rate were smaller in women tested during the late luteal phase than during the follicular phase. Correlation results indicated that AUCg was negatively correlated with PMS scores. These results suggest that measures of cortisol, rather than heart rate or subjective responses to stress, may be most closely associated with PMS. Furthermore, hypo-reactivity of the HPA axis may be pathologically relevant to PMS because it predicts heightened PMS severity.

Neurosteroid, GABAergic and hypothalamic pituitary adrenal (HPA) axis regulation: what is the current state of knowledge in humans?

RATIONALE

A robust epidemiological literature suggests an association between chronic stress and the development of affective disorders. However, the precise biological underpinnings of this relationship remain elusive. Central to the human response and adaptation to stress, activation and inhibition of the hypothalamic pituitary adrenal (HPA) axis involves a multi-level, multi-system, neurobiological stress response which is as comprehensive in its complexity as it is precarious. Dysregulation in this complex system has implications for human stress related illness.

OBJECTIVES

The pioneering research of Robert Purdy and colleagues has laid the groundwork for advancing our understanding of HPA axis regulation by stress-derived steroid hormones and their neuroactive metabolites (termed neurosteroids), which are potent allosteric modulators of GABAA receptor function in the central nervous system. This review will describe what is known about neurosteroid modulation of the HPA axis in response to both acute and chronic stress, particularly with respect to the current state of our knowledge of this process in humans.

RESULTS

Implications of this research to the development of human stress-related illness are discussed in the context of two human stress-related psychiatric disorders - major depressive disorder and premenstrual dysphoric disorder.

CONCLUSIONS

Neurosteroid-mediated HPA axis dysregulation is a potential pathophysiologic mechanism which may cross traditional psychiatric diagnostic classifications. Future research directions are identified.

Affective disturbance associated with premenstrual dysphoric disorder does not disrupt emotional modulation of pain and spinal nociception

In healthy individuals, emotions modulate pain and spinal nociception according to a valence linear trend (ie, pain/nociception is highest during negative emotions and lowest during positive emotions). However, emerging evidence suggests that emotional modulation of pain (but not spinal nociception) is disrupted in fibromyalgia and disorders associated with chronic pain risk (eg, major depression, insomnia). The present study attempted to extend this work and to examine whether women with premenstrual dysphoric disorder (PMDD), a cyclical syndrome associated with debilitating affective symptoms during the late-luteal (premenstrual) phase of the menstrual cycle, is also associated with disrupted emotional modulation of pain. To do so, an affective picture-viewing procedure was used to study emotional modulation of pain and spinal nociception in 14 women with PMDD and 14 control women during mid-follicular, ovulatory, and late-luteal phases of the menstrual cycle (verified by salivary hormone levels and luteinizing hormone tests). At each phase, mutilation, neutral, and erotic pictures were presented to manipulate emotion. During picture viewing, suprathreshold electrocutaneous stimuli were presented to evoke pain and the nociceptive flexion reflex (NFR; a physiological measure of spinal nociception). Statistically powerful linear mixed model analyses confirmed that pictures evoked the intended emotional states in both groups across all menstrual phases. Furthermore, emotion modulated pain and NFR according to a valence linear trend in both groups and across all menstrual phases. Thus, PMDD-related affective disturbance is not associated with a failure to emotionally modulate pain, suggesting that PMDD does not share this pain phenotype with major depression, insomnia, and fibromyalgia.

Is catechol-o-methyltransferase gene polymorphism a risk factor in the development of premenstrual syndrome?

Objective

The objective of this study was to investigate whether there was a correlation between catechol-o-methyltransferase (COMT) gene polymorphism, which is believed to play a role in the etiology of psychotic disorders, and premenstrual syndrome (PMS).

Methods

Fifty-three women with regular menstrual cycles, aged between 18 and 46 years and diagnosed with PMS according to the American Congress of Obstetrics and Gynecology criteria were included in this study as the study group, and 53 healthy women having no health problems were selected as the controls. Venous blood was collected from all patients included in the study and kept at -18℃ prior to analysis.

Results

There was no significant difference between the groups in terms of demographic features such as age, body mass index, number of pregnancies, parity, and number of children. No statistically significant difference was observed in terms of COMT gene polymorphism (p=0.61) between women in the PMS and the control groups. However, a significant difference was found between arthralgia, which is an indicator of PMS, and low-enzyme activity COMT gene (Met/Met) polymorphism (p=0.04).

Conclusion

These results suggested that there was no significant relationship between PMS and COMT gene polymorphism. Since we could not find a direct correlation between the COMT gene polymorphism and PMS, further studies including alternative neurotransmitter pathways are needed to find an effective treatment for this disease.

Treatment of premenstrual dysphoric disorder

Premenstrual dysphoric disorder (PMDD) is comprised of a cluster of affective, behavioral and somatic symptoms recurring monthly during the luteal phase of the menstrual cycle. The disorder affects 3-8% of menstruating women and represents the more severe and disabling end of the spectrum of premenstrual disorders, which includes premenstrual syndrome and premenstrual aggravation of underlying affective disorder. Rigorous and specific diagnostic criteria for PMDD were specified in the Diagnostic and Statistical Manual of Mental Disorders IV (1994) and reaffirmed in the Diagnostic and Statistical Manual of Mental Disorders V (2013) and, consequently, there has been a marked increase in well-designed, placebo-controlled studies evaluating treatment modalities. Although the exact pathogenesis of PMDD is still elusive, treatment of PMDD and severe premenstrual syndrome has centered on neuromodulation via serotonin reuptake inhibitor antidepressants, and ovulation suppression utilizing various contraceptive and hormonal preparations. Unlike the approach to the treatment of depression, serotonergic antidepressants need not be given daily, but can be effective when used cyclically, only in the luteal phase or even limited to the duration of the monthly symptoms. Less, well-substantiated alternative treatments, such as calcium supplementation, agnus castus (chasteberry), Hypericum perforatum (St John's wort) and cognitive/behavioral/relaxation therapies, may be useful adjuncts in the treatment of PMDD. This review provides an overview of current information on the treatment of PMDD.

The association between premenstrual dysphoric disorder and internet use disorder

Premenstrual dysphoric disorder (PMDD) is an important women's mental health issue. This study aimed to investigate the association between Internet use disorder (IUD), PMDD, and their associated factors, such as stress and impulsivity. Women with PMDD (n = 79) and controls (n = 76) were recruited from the community. The diagnoses of PMDD and IUD were confirmed by psychiatric interviews. Participants were evaluated with the Chen Internet Addiction Scale, Perceived Stress Scale, and Barratt Impulsiveness Scale in both the premenstrual and follicular phases. Women with PMDD were more likely to have IUD. Women with PMDD had greater severity of IUD, perceived stress, and impulsivity than the control group in the premenstrual phase. Impulsivity mediated the association between PMDD and IUD, while both impulsivity and perceived stress mediated the association between PMDD and IUD severity. Thus, IUD should be evaluated and treated among women with PMDD, particularly for those with higher impulsivity or higher perceived stress. Strategies for stress management and counseling for impulsivity should be provided to women with PMDD, particular to those comorbid with IUD.

Menstrual mood disorders are associated with blunted sympathetic reactivity to stress

OBJECTIVE

Few studies have directly compared women with a menstrually related mood disorder (MRMD) with women who have suffered from depression for stress reactivity phenotypes. It is unclear whether blunted responses to stress in women with a MRMD reflect a unique phenotype of MRMDs or may be explained by a history of depression.

METHODS

We assessed cardiovascular reactivity to stress in four groups: 1) Women with a MRMD without a history of depression (n=37); 2) women with a MRMD plus a history of depression (n=26); 3) women without a MRMD and without a history of depression (n=43); and 4) women without a MRMD but with a history of depression (n=20).

RESULTS

Women with a MRMD showed blunted myocardial (heart rate and cardiac index) reactivity to mental stress compared to non-MRMD women, irrespective of histories of depression. Hypo-reactivity to stress predicted greater premenstrual symptom severity in the entire sample. Women with a MRMD showed blunted norepinephrine and diastolic blood pressure stress reactivity relative to women with no MRMD, but only when no history of depression was present. Both MRMD women and women with depression histories reported greater negative subjective responses to stress relative to their non-MRMD and never depressed counterparts.

CONCLUSION

Our findings support the assertion that a blunted stress reactivity profile represents a unique phenotype of MRMDs and also underscore the importance of psychiatric histories to stress reactivity. Furthermore, our results emphasize the clinical relevance of myocardial hypo-reactivity to stress, since it predicts heightened premenstrual symptom severity.

Luteal serum BDNF and HSP70 levels in women with premenstrual dysphoric disorder

Premenstrual dysphoric disorder (PMDD) is a severe form of premenstrual syndrome characterized by psychological and somatic symptoms commencing in the luteal phase of the menstrual cycle and concludes with menstrual bleeding. PMDD affects 3-8 % of premenopausal women and represents a significant public health problem especially in young women. Decreased brain-derived neurotrophic factor (BDNF) levels are associated with several mental disorders. Heat-shock protein-70 (HSP70) is an important member of the molecular chaperone system, which provides a molecular defense against proteotoxic stress. We hypothesized that there would be changed levels of BDNF and HSP70 in women with PMDD compared with non-symptomatic women, reflecting impaired and/or activated stress-related responses involved in the underlying pathogenesis of PMDD. Female medical students were screened, and 24 women without premenstrual symptoms and 25 women with PMDD were enrolled in the study. Psychiatric evaluation and the Daily Record of Severity of Problems-Short Form were used for two consecutive menstrual cycles to diagnose PMDD. Serum BDNF and HSP70 levels were assessed in the third luteal phase. Participants with PMDD had significantly higher serum BDNF and HSP70 levels compared with controls, and there was a significant positive correlation between serum BDNF and HSP70 levels. Increased HSP70 levels may reflect cellular distress in PMDD. Increased serum BDNF levels in the luteal phase in subjects with PMDD may reflect a compensation process, which results in subsequent improvement of PMDD-associated depressive symptoms in the follicular phase. Thus, increased serum BDNF levels may be indicative of a compensating capacity in PMDD.

Premenstrual dysphoria and luteal stress in dominant-social-status female macaques

The current study aims to extend our previous work to develop nonhuman primate model for prospectively studying the mechanism underlying premenstrual dysphoric disorder (PMDD). Thirty young dominant-status female monkeys were randomly divided into the control group, the model group, and JQP group. For two consecutive menstrual cycles, from day 18 to 22, monkeys in the model and JQP groups were housed and immobilized singly in specially designed isolation cages for 5-6 hours per day. At the same time, the pharmaceutical interference effect of jingqianping (JQP) granule, a traditional Chinese medicine specifically used to cure PMDD patients, was tested using monkeys in the JQP group. The behavior and facial expressions of monkeys were photographed with an automatic vidicon and were quantitatively analyzed by "the emotion evaluation scale of female experimental macaque." Changes in serum level of progesterone and estradiol were measured with RIA, and serum level of 5-HT, noradrenaline, and dopamine were measured with HPLC. After experiencing mentioned above stress, 70% of monkeys of model group showed PMDD symptoms during three consecutive menstrual cycles. Estradiol and progesterone serum level decreased (P < 0.01). Moreover, the peak value of secreted hormones in their follicular phase did not occur. Serum level of 5-HT and dopamine were significantly lower (P < 0.01), but the serum noradrenaline level was higher (P < 0.01). Moreover, in monkeys administered by JQP granule, both PMDD symptoms and the anormal serum level of neurotransmitters could be obviously reversed. This special luteal-phase treatment on dominant-social-status monkeys might be a feasible way to create models mimicking PMDD.

Beta-adrenergic receptor mechanisms and pain sensitivity in women with menstrually related mood disorders

Somatic symptoms experienced by women with a menstrually related mood disorder (MRMD) during their premenstrual luteal phase contribute to functional impairment. Yet, investigations on pathophysiological mechanisms contributing to heightened pain sensitivity in MRMD are sparse. During the luteal phase, 61 women with an MRMD and 61 non-MRMD controls were evaluated for β-adrenergic receptor (β-AR) responsivity using the isoproterenol sensitivity test. A subset (43 MRMD and 50 non-MRMD) then entered a double-blind, placebo-controlled, crossover protocol to examine the effect of β-AR blockade with intravenous propranolol on sensitivity to experimental (cold pressor and ischemic) and clinical (McGill Pain Questionnaire score) pain. Women with an MRMD exhibited greater β1- and β2-AR responsivity, ischemic pain intensity, and affective clinical pain ratings than controls. Propranolol increased cold pressor pain tolerance in both groups, but it decreased cold pain intensity and ischemic pain unpleasantness ratings only in non-MRMD women. In contrast, propranolol decreased affective ratings of clinical pain in women with MRMD. Exploratory analyses indicated that only in MRMD women did greater β-AR responsivity predict greater sensitivity to cold pressor and ischemic pain. This study provides the first evidence for a role of β-AR mechanisms in the hyperalgesia and clinical pain experienced by women with MRMDs.

PERSPECTIVE

This article describes the effects of β-adrenergic receptor stimulation and blockade on experimental and clinical pain sensitivity in women with an MRMD. The results of this study may have implications for the management of the substantial somatic premenstrual symptomatology experienced by women with an MRMD.

Allopregnanolone serum concentrations and diurnal cortisol secretion in women with premenstrual dysphoric disorder

Most prior studies in patients with premenstrual dysphoric disorder (PMDD) indicate a blunted hypothalamus-pituitary-adrenal axis function. However, the relationship between neuroactive progesterone metabolites, such as allopregnanolone, and hypothalamus-pituitary-adrenal (HPA) axis function in PMDD patients is relatively sparsely studied. The primary aims of this study were to assess diurnal variation in circulating cortisol and low-dose dexamethasone suppression in PMDD patients and healthy controls, and the relationship between these two HPA axis indices and allopregnanolone serum concentrations. Twenty-six women with prospectively defined PMDD and 30 healthy controls were recruited. Participants underwent diurnal sampling for cortisol serum concentrations and a low-dose dexamethasone suppression test. In addition, morning allopregnanolone serum concentrations were determined. There was no difference in diurnal secretion of cortisol and degree of dexamethasone suppression of cortisol between PMDD patients and healthy controls. However, PMDD patients with high allopregnanolone levels displayed blunted nocturnal cortisol levels in comparison with healthy controls who had low allopregnanolone serum concentrations. In women with PMDD, diurnal secretion of cortisol may be influenced by allopregnanolone levels of the luteal phase. This finding may be attributed to timing of blood sampling in the late luteal phase as well as the individual level of allopregnanolone but could potentially explain the discrepancies in results between studies examining HPA axis function in women with PMDD.

A rodent model of premenstrual dysphoria: progesterone withdrawal induces depression-like behavior that is differentially sensitive to classes of antidepressants

Premenstrual dysphoric disorder (PMDD) is characterized by a range of physical and affective symptoms including anxiety, irritability, anhedonia, social withdrawal and depression. We demonstrate robust and reproducible depression-like behavior during progesterone withdrawal (PWD) protocols with different methodological variables. Comparable immobility in the forced swim test was evident with different routes of administration (i.e. injections vs. implants), with and without exogenous estrogens in addition to progesterone, and in both single and multiple withdrawal paradigms. Furthermore, withdrawal from physiological doses of progesterone resulted in modest social withdrawal in the social preference test and anhedonia in the saccharin preference test without altering general activity levels or total liquid consumption. However, progesterone withdrawal did not alter serotonin levels in the cortex or hippocampus. Furthermore tryptophan depletion did not augment immobility during PWD. Neither fluoxetine nor duloxetine reduced depression-like behavior during PWD in the forced swim test. In contrast, the tricyclic antidepressant, amitriptyline, was effective in reducing the immobility in forced swim test. These data demonstrate that progesterone withdrawal is a reproducible model of PMDD in several critical behavioral domains. Furthermore, these data do not support alterations in serotonin levels in the etiology of hormonally induced depression.

Effects of panel sex composition on the physiological stress responses to psychosocial stress in healthy young men and women

Men and women differ in regard to psychosocial stress responses. Biological and contextual factors are known to mediate these differences; however, few studies investigated their interaction. In the present study, we examined contributions of both contextual and biological factors to the stress response of young healthy adults. Men and women were exposed to a modified version of Trier Social Stress Test. The participants gave a speech in front of a panel of judges, composed of either male or female panelists. Both men, and women presented a cortisol increase only when exposed to opposite sex panelists. Interestingly, this effect was only observed in women in their follicular phase. This finding showed that the induction of a psychosocial stress response does not strictly rely on direct social evaluation, but also depends on the sex composition of the panel. Implications for future studies are discussed.

The interrelation between premenstrual syndrome and major depression: results from a population-based sample

BACKGROUND

Research about the relationship between premenstrual syndrome (PMS) and major depression is limited. This study examined the relationship between moderate to severe PMS and major depression in a population-based sample of women of reproductive age. The objectives of the study were to assess the association between premenstrual syndrome and major depression, to analyse how PMS and major depression differ and to characterise the group of women who report both PMS and major depression.

METHODS

Data were obtained from the Swiss Health Survey 2007. Included in the analysis was data from women under the age of 55 without hysterectomy and who answered the questions on PMS symptoms. The population-based sample consisted of 3518 women. Weighted prevalence rates were calculated and relative risk ratios for PMS, major depression and women who reported both PMS and major depression, were calculated with logistic multinominal logit regression.

RESULTS

The prevalence of major depression was 11.3% in women screening positive for moderate PMS and 24.6% in women screening positive for severe PMS. Compared to women without any of these conditions, women who reported moderate to severe alcohol consumption had a lower risk for PMS. Women reporting use of antidepressants, and use of oral contraceptives had a higher risk for major depression compared to women without any of these conditions. Women reporting work dissatisfaction had a higher risk for PMS. A higher relative risk to report both PMS and major depression compared to women without PMS or major depression was related to factors such as high psychological distress, low mastery, psychotropic drug consumption, and low self-rated health.

CONCLUSIONS

The results suggested that women who suffer from both PMS and major depression are more impaired compared to women with only one disorder. The results further indicated that PMS and major depression are different disorders that can, however, co-occur.
