Blunted Cortisol Response to Acute Psychosocial Stress in Women With Premenstrual Dysphoric Disorder.

BACKGROUND: Despite being considered a stress-related condition, it is not known whether the hypothalamic-pituitary-adrenal (HPA) axis is dysfunctional in response to acute psychosocial stress in premenstrual dysphoric disorder (PMDD). This is problematic because many women with PMDD report that they are not able to control their stress levels, and a blunted cortisol output has been identified in women with related psychiatric conditions, such as anxiety and depression. The present study is a part of the Premenstrual Hormonal and Affective State Evaluation (PHASE) project, and it aimed to characterize the cortisol trajectory in response to an acute psychosocial stress challenge. METHODS: Women with PMDD and healthy controls with confirmed ovulatory cycles underwent the Trier Social Stress Test (TSST) procedure in the mid-late luteal phase of the menstrual cycle, throughout which we collected serum samples of cortisol that we analyzed using ultra-performance liquid chromatography tandem mass spectrometry. RESULTS: The linear mixed model analysis indicated a significant time*diagnosis interaction (P = .008) such that women with PMDD displayed significantly lower serum cortisol levels at +40 through +90 minutes from the time of stress induction. CONCLUSION: This is the first study to show that women with PMDD have a blunted cortisol response to psychosocial stress. Combined with our earlier finding showing a greater parasympathetic nervous system withdrawal on heart oscillations in PMDD during acute stress, these and other results show that the dysregulated processing of stress in PMDD may be captured using objective study measures.

The impact of comorbid premenstrual syndrome or premenstrual dysphoric disorder on the clinical characteristics of bipolar disorder among Han Chinese women.

Bipolar disorder (BD) is commonly comorbid with premenstrual syndrome (PMS) or premenstrual dysphoric disorder (PMDD). However, little is known about their relationship. This study aimed to assess the impact of comorbid PMS or PMDD on the clinical characteristics of BD. A cross-sectional study was conducted on 262 women with BD. PMS and PMDD were screened with the Premenstrual Symptoms Screening Tool (PSST). Symptomatic features were assessed with Hamilton Depression Scale (HAMD), Young Mania Rating Scale (YMRS), and atypical features by the depressive episode section of SCID-I/P. The rates of PMS and PMDD among BD were 57.6% and 20.6% according to PSST. No significant difference in the rates of PMS and PMDD was found between BD I, BD II, and BD-NOS. Compared to BD patients without PMS or PMDD, patients with comorbid BD and PMS or PMDD were younger, more educated, had a higher risk of OCD, had an earlier age of onset, scored higher on HAMD-17 and its sub-scale of anxiety/somatization, cognitive deficit, psychomotor retardation, and were more likely to have increased appetite and leaden paralysis. In addition, patients with comorbid BD and PMDD were less likely to experience traumatic life events, more likely to have family history of mental disorders and have inflammatory or autoimmune disease, scored higher on HMAD-17, particularly in its sub-scale of anxiety/somatization, cognitive deficit, psychomotor retardation, and sleep disturbance. Compared with BD without PMS or PMDD, BD with PMS or PMDD might be a specific subtype of BD characterized with earlier onset age, heavier genetic load, increased symptom severity, and atypical features.

Determinants of premenstrual dysphoric disorder and associated factors among regular undergraduate students at Hawassa University Southern, Ethiopia, 2023: institution-based cross-sectional study.

BACKGROUND: Premenstrual dysphoric disorder (PMDD) is a condition causing severe emotional, physical, and behavioral symptoms before menstruation. It greatly hinders daily activities, affecting academic and interpersonal relationships. Attention is not given to premenstrual disorders among female students in higher education. As a result, students are susceptible to stress, and their academic success is influenced by various factors, including their menstrual cycle, and the long-term outcomes and consequences are poorly researched. Even though PMDD has a significant negative impact on student's academic achievement and success limited research has been conducted in low- and middle-income countries including Ethiopia, especially in the study setting. Therefore, a study is needed to assess premenstrual dysphoric disorder and associated factors among regular undergraduate students at Hawassa University. METHODS: An institutional-based cross-sectional study was conducted among 374 regular undergraduate female students at Hawassa University, College of Medicine and Health Sciences. A self-administered structured premenstrual symptoms screening tool for adolescents was used to assess premenstrual dysphoric disorder. The collected data were loaded into a statistical package for the social science version 25 and analyzed using it. Both bivariate and multivariate logistic regression were used to identify factors associated with premenstrual dysphoric disorder. Each independent variable was entered separately into bivariate analysis, and a variable with a p-value less than 0.25 were included in the multivariate analysis to adjust the possible confounders. Statistically significant was declared at a 95% confidence interval when variable with a p-value less than 0.05 in the multivariate analysis with premenstrual dysphoric disorder. RESULTS: The magnitude of premenstrual dysphoric disorder in this study was 62.6% (95% CI 57.4-67.5). Having severe premenstrual pain (AOR = 6.44;95%CI 1.02-40.73), having irregular menstrual cycle (AOR = 2.21; 95% CI 1.32-3.70), students who had poor social support (AOR = 5.10;95%CI, (2.76-12.92) and moderate social support (AOR = 4.93;95%CI (2.18-11.18), and students who used contraception (AOR = 3.76;95%CI, 2.21-6,40) were statistically significant factors with the outcome variable. CONCLUSION: The prevalence of premenstrual dysphoric disorder was high as compared to other studies. There was a strong link between irregular menstrual cycle, severe menstrual pain (severe dysmenorrhea), poor social support, and contraception use with premenstrual dysphoric disorder. This needs early screening and intervention to prevent the complications and worsening of the symptoms that affect students' academic performance by the institution.

Prevalence and correlates of premenstrual syndrome and premenstrual dysphoric disorder among women aged 18-25 in Turkey.

OBJECTIVE: Premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) are experienced in the luteal phase among women of reproductive age and are known to affect quality of life. This study sought to determine the prevalence and correlates of PMS and PMDD in women aged 18-25 in Turkey. METHOD: A cross-sectional study was conducted between December 2022 and May 2023, which recruited 1125 female college students. A personal information form, the International Physical Activity Questionnaire, and the Premenstrual Syndrome Scale (PMSS) were administered. Participants who met criteria for PMS during three consecutive menstrual cycles based on the ACOG and PMSS scores were diagnosed as having PMS. Participants who met the criteria for PMDD during three consecutive menstrual cycles based on the DSM-V were diagnosed as having PMDD. Logistic regression analysis was used to determine correlates of PMS and PMDD. FINDINGS: PMS was found in 49.2% and PMDD in 48.0% of the participants. Women having a blood group type B compared to those with blood group type A were more likely to have PMS (OR = 151.8, 95% CI = 54.5-422.6). In addition, women with PMS were less likely to be physically active based on the metabolic equivalent of task score (OR = 0.99, 95% CI= 0.98-0.99). Menstrual cycle duration was also longer among those with PMDD (OR = 1.47, 95% CI= 1.25-1.72), as was daily caffeine intake (OR = 1.01, 95% CI= 1.00-1.01). PMDD score was also found to be associated with major depressive disorder (OR = 1.06,95% = 1.05-1.07). CONCLUSIONS: PMS and PMDD among young women in Turkey were associated with blood groups, MET scores, and other clinical characteristics that may help clinicians to identify these conditions.

Menstrual and psychosocial characteristics associated with high-risk of premenstrual dysphoric disorder among university students: a cross-sectional study.

Up to 92 percent of Chinese women of reproductive age have pre-menstrual syndrome (PMS). The severe form of PMS (i.e. pre-menstrual dysphoric disorder [PMDD]) negatively affects women's everyday functioning and reproductive health. This study examined the relationships between menstrual, psychosocial characteristics and the risk of PMDD among young Chinese women. A cross-sectional online survey was conducted among Chinese university students in Hong Kong. Logistic regression was used to compute adjusted odds ratio (aOR) for the association of high-risk PMDD with menstrual and psychosocial characteristics. A total of 541 Chinese university students were recruited. Approximately 53 percent of female students were at high risk of developing PMDD. The high-risk PMDD group was significantly associated with a heavy volume of menstrual flow (aOR = 2.17, 95 percent CI 1.06-4.45), irregular menstrual cycle (1.72, 1.17-2.52), high dysmenorrhea (2.80, 1.95-4.04) and older ages of menarche (0.67, 0.45-0.98) in the menstrual characteristics. In the psychosocial characteristics, high-risk PMDD was significantly associated with symptoms of anxiety (2.19, 1.48-3.32) and depression (2.22, 1.48-3.32), high loneliness (1.94, 1.34-2.79) and low resilience (2.21, 1.52-3.23) levels. Additionally, resilience had a potential moderating effect on the associations between the high risk of PMDD and anxiety, depression and loneliness. The development and delivery of interventions that can enhance resilience and manage psychological distress would be beneficial for young Chinese women's reproductive health.

[Premenstrual syndrome and premenstrual dysphoric disorder-Overview on pathophysiology, diagnostics and treatment]. / Prämenstruelles Syndrom und prämenstruelle dysphorische Störung ­ Übersicht zu Pathophysiologie, Diagnostik und Therapie.

Premenstrual syndrome and premenstrual dysphoric disorder become episodically manifest during the second half of the female menstrual cycle and are characterized by psychological and physical symptoms causing relevant functional and social impairments. Mood swings, depression and dysphoria are associated depressive symptoms. Therefore, affective disorders should be considered as a differential diagnosis. Of women in reproductive age 3-8% suffer from premenstrual syndrome and 2% of women are affected by premenstrual dysphoric disorder. Genetic and sociobiographical risk factors are discussed. Furthermore, genetic polymorphisms of specific hormone receptors are considered to be genetic risk factors. From a pathophysiological perspective premenstrual syndrome and premenstrual dysphoric disorder are caused by a complex interaction between cyclic changes of ovarian steroids and central neurotransmitters. An imbalance of estrogen and progesterone in the luteal phase is believed to cause the symptoms. Therefore, the first treatment approach consists of regulation of the menstrual cycle or luteal support with progesterone or synthetic progestins even if their effectiveness has not yet been proven in randomized controlled studies and meta-analyses. The administration of combined oral contraceptives is also an option. Especially treatment with selective serotonin reuptake inhibitors (SSRI) represent an evidence-based approach. In severe cases the administration of gonadotropin releasing hormone (GnRH) agonists with add back treatment can also be considered. In the field of affective disorders premenstrual syndromes represent clinically relevant differential diagnoses and comorbidities, which confront the treating physician with particular clinical challenges. Therefore, this literature review gives the readership a clinical orientation for dealing with these disorders.

[Premenstrual dysphoric disorder (PMDD): Drug and psychotherapeutique management, a literature review]. / Trouble dysphorique prémenstruel : prises en charge médicamenteuses et psychothérapeutiques, une revue de littérature.

INTRODUCTION: Premenstrual Dysphoric Disorder (PMDD) was first recognised in July 2013 in the DSM-5 after a long journey to identify its existence. It was not until 1983 that the US National Institute of Mental Health determined research criteria for the study of PMS. In 1994, the term "premenstrual dysphoric disorder" (PMDD) replaced this term in the 4th edition of the Diagnostic System Manual (DSM). It was listed in the section "Mood Disorder Not Otherwise Specified" and remained under consideration until the DSM-5, in which it appeared in the depressive disorders section. The legitimisation of the psychiatric diagnosis as well as the determination of clear symptomatology criteria in 2013 opened up possibilities for management, development of clinical, pathophysiological, therapeutic and psychotherapeutic studies. This disabling disorder can affect personal, social, family and professional life. In 2019, the ICD-11 in turn introduced the diagnosis of premenstrual dysphoric disorder, which solidifies the recognition of the disorder. OBJECTIVE: (I) to review the existing treatments, both medicinal and psychotherapeutic, and (II) to review their effectiveness. At the end of this work we will formulate recommendations for the management of these patients. METHODOLOGY: A bibliographic search was carried out from 7 June 2021 to 7 July2021 on the databases (bases de données) Psychinfo APA, Scopus, PubMed, as well as the bases de données of the Cochrane organisation and the recommendation documents of the Haute Autorité de la santé. After an initial selection based on keywords, the full text of all articles were read to arrive at the final selection of 32 articles. RESULTS: Antidepressants and Cognitive Behavioural Therapies (CBT) appear to be the most commonly recommended treatments for PMDD. Other research shows the effectiveness of oral contraceptives including drospirenone. Selective serotonin reuptake inhibitors (SSRIs) were identified as an effective treatment for PMDD. These data are consistent with the current etiological hypothesis of PMDD which has a negative impact of natural hormonal fluctuations on certain neurotransmitters. CBT showed positive results in reducing the functional impact of PMDD. DISCUSSION: Selective serotonin reuptake inhibitor (SSRI) antidepressants were reported to be first-line treatments for PMDD (sertraline 50-150 mg/d, fluoxetine 10-20 mg/d, escitalopram 10-20 mg/d, paroxetine 12.5-25 mg/d). Drospirenone (EE 3 mg and EE 20 mg/d 24 days of hormonal pills, 4 days inactive) appears to have been a first or second line treatment depending on the articles. Current results clearly point to the effectiveness of CBT in helping to reduce: functional impairment, depressed mood, feelings of hopelessness, anxiety, mood swings, sensitivity, irritability, insomnia, conflict with others, impact of premenstrual symptoms on daily life, intensity of symptoms experienced, and symptom handicap. CBTs could also become a first-line treatment if there were to be more evidence of their effectiveness. In the future, it would seem useful to offer a psychotherapeutic treatment that can be reproduced and to multiply research with a high level of scientific comparability in order to clarify the place of CBT in the management of PMDD. Research on the etiopathology of the disorder and the optimal drug regimen is still ongoing. There is a need to develop appropriate psychotherapeutic techniques to support and accompany these patients. CONCLUSION: In order to better evaluate treatments for PMDD, there is a need to homogenise studies on the subject at several levels: design, treatment doses, psychotherapeutic techniques, and evaluation measures. At present, some studies include both premenstrual syndrome (PMS) and PMDD patients. PMS and PMDD do not include the same symptoms, nor the same severity and potentially the same aetiology in the patients studied. In order to propose rigorous research that evaluates the effectiveness of treatments for PMDD and to properly support people with both these disorders, it seems essential to distinguish the two conditions. The role of the health practitioner is to be able to identify PMDD by differentiating it from other clinically related disorders. The patient must then be accompanied to make a choice of treatment adapted to her symptoms, their severity, her history, her plans for procreation, contraindications and her preferences. In 2021, the French National Authority for Health did not offer any guidelines or recommendations for the management of premenstrual dysphoric disorder. There is a need to develop research in France.

Can animal models resemble a premenstrual dysphoric condition?

Around 80% of women worldwide suffer mild Premenstrual Disorders (PMD) during their reproductive life. Up to a quarter are affected by moderate to severe symptoms, and between 3% and 8% experience a severe form. It is classified as premenstrual syndrome (PMS) with predominantly physical symptoms and premenstrual dysphoric disorder (PMDD) with psychiatric symptoms. The present review analyzes the factors associated with PMD and the Hypothalamus-Pituitary-Ovarian or Hypothalamus-Pituitary-adrenal axis and discusses the main animal models used to study PMDD. Evidence shows that the ovarian hormones participate in PMDD symptoms, and several points of regulation of their synthesis, metabolism, and target sites could be altered. PMDD is complex and implies several factors that require consideration when this condition is modeled in animals. Of particular interest are those points related to areas that may represent opportunities to develop new approximations to understand the mechanisms involved in PMDD and possible treatments.

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.

Does Symptom-Onset Treatment With Sertraline Improve Functional Impairment for Individuals With Premenstrual Dysphoric Disorder?: A Randomized Controlled Trial.

PURPOSE/BACKGROUND: Daily treatment with sertraline improves functional impairment among individuals with premenstrual dysphoric disorder (PMDD). We do not know whether treatment initiated at symptom onset also improves functional impairment. METHODS/PROCEDURES: This 3-site, double blind, randomized, clinical trial compared sertraline (25-100 mg) to similar appearing placebo, both administered at symptom onset, for reduction of PMDD symptoms. Ninety participants were allocated to sertraline and 94 participants to placebo. Functional outcomes from the Daily Ratings of the Severity of Problems included (1) reduced productivity or efficiency at work, school, home, or daily routine; (2) interference with hobbies or social activities; and (3) interference with relationships. Items were measured from 1 (no interference) to 6 (extreme interference) and averaged for the final 5 luteal phase days. This secondary analysis examined whether improvement in functional domains was greater for those allocated to sertraline compared with placebo. Second, we used causal mediation analyses to explore whether specific PMDD symptoms mediated functional improvement. RESULTS/FINDINGS: Only relationship functioning improved significantly with active treatment between baseline and the end of the second cycle (active group mean [SD] change, -1.39 [1.38]; placebo group mean change, -0.76 [1.20]; ß = -0.40; SE, 0.15; P = 0.009). The total effect of treatment on interference was -0.37 (95% confidence interval [CI], -0.66 to -0.09; P = 0.011). Given the nonsignificant direct effect (0.11; 95% CI, -0.07 to 0.29; P = 0.24) and significant indirect effect (-0.48; 95% CI, -0.71 to -0.24; P < 0.001), amelioration of anger/irritability likely mediated reductions in relationship interference. IMPLICATIONS/CONCLUSIONS: That anger/irritability mediates impairments in relationship functioning has face validity but should be replicated in other data sets. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT00536198 .

Agmatine prevents the manifestation of impulsive burying and depression-like behaviour in progesterone withdrawn female rats.

Premenstrual dysphoric disorder (PMDD) is characterized by various physical and affective symptoms, including anxiety, irritability, anhedonia, social withdrawal, and depression. The present study investigated the role of the agmatinergic system in animal model of progesterone withdrawal in female rats. Chronic progesterone exposure of female rats for 21 days and its abrupt withdrawal showed enhanced marble burying, increased immobility time, and reduced no. of entries in open arm as compared to control animals. The progesterone withdrawal-induced enhanced marble burying anxiety and immobility time was significantly attenuated by agmatine (5-20 mg/kg, i.p.), and its endogenous modulators like L-arginine (100 mg/kg, i.p.), amino-guanidine (25 mg/kg, i.p.) and arcaine (50 mg/kg, i.p.) by their once-daily administration from day 14-day 21 of the protocol. We have also analysed the levels of agmatine, progesterone, and inflammatory cytokines in the hippocampal region of progesterone withdrawn rats. There was a significant decline in agmatine and progesterone levels and an elevation in cytokine levels in the hippocampal region of progesterone withdrawn rats compared to the control animals. In conclusion, the present studies suggest the importance of the endogenous agmatinergic system in progesterone withdrawal-induced anxiety-like and depression-like behaviour. The data also projects agmatine as a potential therapeutic target for the premenstrual dysphoric disorder.

Oral contraceptives containing drospirenone for premenstrual syndrome.

BACKGROUND: Premenstrual syndrome (PMS) is a common problem. Premenstrual dysphoric disorder (PMDD) is a severe form of premenstrual syndrome. Combined oral contraceptives (COC), which provide both progestin and oestrogen, have been examined for their ability to relieve premenstrual symptoms. A combined oral contraceptive containing drospirenone and a low oestrogen dose has been approved for treating PMDD in women who choose combined oral contraceptives for contraception. OBJECTIVES: To evaluate the effectiveness and safety of COCs containing drospirenone in women with PMS. SEARCH METHODS: We searched the Cochrane Gynaecology and Fertility Group trial register, CENTRAL (now containing output from two trials registers and CINAHL), MEDLINE, Embase, PsycINFO, LILACS, Google Scholar, and Epistemonikos on 29 June 2022. We checked included studies' reference lists and contacted study authors and experts in the field to identify additional studies. SELECTION CRITERIA: We included randomised controlled trials (RCT) that compared COCs containing drospirenone with placebo or with another COC for treatment of women with PMS. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures recommended by Cochrane. The primary review outcomes were effects on premenstrual symptoms that were prospectively recorded, and withdrawal due to adverse events. Secondary outcomes included effects on mood, adverse events, and response rate to study medications. MAIN RESULTS: We included five RCTs (858 women analysed, most diagnosed with PMDD). The evidence was very low to moderate quality; the main limitations were serious risk of bias due to poor reporting of study methods, and serious inconsistency and imprecision. COCs containing drospirenone and ethinylestradiol (EE) versus placebo COCs containing drospirenone and EE may improve overall premenstrual symptoms (standardised mean difference (SMD) -0.41, 95% confidence interval (CI) -0.59 to -0.24; 2 RCTs, N = 514; I2 = 64%; low-quality evidence); and functional impairment due to premenstrual symptoms in terms of productivity (mean difference (MD) -0.31, 95% CI -0.55 to -0.08; 2 RCTs, N = 432; I2 = 47%; low-quality evidence), social activities (MD -0.29, 95% CI -0.54 to -0.04; 2 RCTs, N = 432; I2 = 53%; low-quality evidence), and relationships (MD -0.30, 95% CI -0.54 to -0.06; 2 RCTs, N = 432; I2 = 45%; low-quality evidence). The effects from COCs containing drospirenone may be small to moderate. COCs containing drospirenone and EE may increase withdrawal from trials due to adverse effects (odds ratio (OR) 3.41, 95% CI 2.01 to 5.78; 4 RCT, N = 776; I2 = 0%; low-quality evidence). This suggests that if you assume the risk of withdrawal due to adverse effects from placebo is 3%, the risk from drospirenone plus EE will be between 6% and 16%. We are uncertain of the effect of drospirenone plus EE on premenstrual mood symptoms, when measured by validated tools that were not developed to assess premenstrual symptoms. COCs containing drospirenone may lead to more adverse effects in total (OR 2.31, 95% CI 1.71 to 3.11; 3 RCT, N = 739; I2 = 0%; low-quality evidence). This suggests that if you assume the risk of having adverse effects from placebo is 28%, the risk from drospirenone plus EE will be between 40% and 54%. It probably leads to more breast pain, and may lead to more nausea, intermenstrual bleeding, and menstrual disorder. Its effect on nervousness, headache, asthenia, and pain is uncertain. There was no report of any rare but serious adverse effects, such as venous thromboembolism in any of the included studies. COCs containing drospirenone may improve response rate (OR 1.65, 95% CI 1.13 to 2.40; 1 RCT, N = 449; I2 not applicable; low-quality evidence). This suggests that if you assume the response rate from placebo is 36%, the risk from drospirenone plus EE will be between 39% and 58%. We did not identify any studies that compared COCs containing drospirenone with other COCs. AUTHORS' CONCLUSIONS: COCs containing drospirenone and EE may improve premenstrual symptoms that result in functional impairments in women with PMDD. The placebo also had a significant effect. COCs containing drospirenone and EE may lead to more adverse effects compared to placebo. We do not know whether it works after three cycles, helps women with less severe symptoms, or is better than other combined oral contraceptives that contain a different progestogen.

Exploring diagnosis and treatment of premenstrual dysphoric disorder in the U.S. healthcare system: a qualitative investigation.

BACKGROUND: Premenstrual Dysphoric Disorder (PMDD) is a premenstrual condition that affects 3-8% of the US population, yet knowledge on treatment and consistent diagnostic testing is lacking. While research concerning the epidemiology and pharmaceutical treatments for this condition has increased, there is a lack of qualitative studies on the experiences of patients who live with this condition. The aim of this study was to explore the diagnostic and treatment experiences of PMDD patients in the U.S. healthcare system and identify barriers to diagnosis and treatment. METHODS: This study uses a feminist framework with qualitative phenomenological methods. We recruited participants who identified as having PMDD, regardless of official diagnosis, through online forums within the U.S. PMDD community. The study conducted 32 in depth interviews with participants on their experiences with PMDD diagnosis and treatment. Thematic analysis methods revealed key barriers within the diagnostic and care process including patient, provider, and societal barriers. RESULTS: This study presents a PMDD Care Continuum that represents the timeline of participant experiences beginning from symptom onset towards official diagnosis, treatments, and ongoing management of the condition. Participant experiences demonstrated that much of the diagnostic and treatment processes were burdened on the patient, and that successful navigation within the healthcare system was dependent on high levels of self-advocacy. CONCLUSIONS: This was the first study to describe the qualitative experiences of patients who identified as having PMDD in the U.S. Further research is needed to refine and operationalize diagnostic criteria and treatment guidelines for PMDD.

A 1-week sleep and light intervention improves mood in premenstrual dysphoric disorder in association with shifting melatonin offset time earlier.

To test the hypothesis that 1 week of combined sleep and light interventions (SALI), which phase-advance (shift earlier) melatonin circadian rhythms, improves mood significantly more than phase-delay (shift later) SALI. After a 2-month diagnostic evaluation for premenstrual dysphoric disorder (PMDD per DSM-5 criteria) in a university clinical research setting, 44 participants enrolled in baseline studies were randomized in the luteal phase at home to (A) a phase-advance intervention (PAI): 1 night of late-night wake therapy (LWT: sleep 9 pm-1 am) followed by 7 days of the morning (AM) bright white light (BWL), or (B) a phase-delay intervention (PDI): 1 night of early-night wake therapy (EWT: sleep 3-7 am) plus 7 days of the evening (PM) BWL. After a month of no intervention, participants underwent the alternate intervention. Outcome measures were mood, the melatonin metabolite, 6-sulfatoxymelatonin (6-SMT), and actigraphy (to assess protocol compliance). At baseline, atypical depression correlated positively with phase delay in 6-SMT offset time (r = .456, p = .038). PAI advanced 6-SMT offset from baseline more than PDI (p < .05), and improved raw mood scores more than PDI (p < .05). As hypothesized, percent improvement in mood correlated positively with a phase advance from baseline in 6-SMT offset time (p < .001). Treatment with 1 night of advanced/restricted sleep followed by 7 days of AM BWL (PAI) was more efficacious in reducing PMDD depression symptoms than a PDI; mood improvement occurred in association with phase advance in 6-SMT offset time. Combined SALIs offer safe, efficacious, rapid-acting, well-tolerated, non-pharmacological, non-hormonal, affordable, repeatable home interventions for PMDD. Clinical Trials.gov NCT # NCT01799733.

Associations of premenstrual symptoms with daily rumination and perceived stress and the moderating effects of mindfulness facets on symptom cyclicity in premenstrual syndrome.

Subthreshold premenstrual symptoms can be impairing even if the diagnostic criteria for premenstrual dysphoric disorder (PMDD) are not reached. Previous research suggests shared psychological risk factors without a clear differentiation of premenstrual syndrome (PMS) from PMDD. This study focuses on a sample with a wide range of premenstrual symptoms not reaching PMDD-criteria and aims to investigate within-person associations of premenstrual symptoms with daily rumination and perceived stress during the late luteal phase as well as cycle-phase specific associations of habitual mindfulness including present-moment-awareness and acceptance with premenstrual symptoms and impairment. Fifty-six naturally cycling women with self-reported premenstrual symptoms completed an online diary on premenstrual symptoms, rumination and perceived stress over two consecutive menstrual cycles, and baseline questionnaires on habitual present-moment-awareness and acceptance. Multilevel analyses revealed cycle-related variations in premenstrual symptoms and impairment (all ps < .001). Higher within-person levels of core and secondary premenstrual symptoms during the late luteal phase predicted increased daily rumination and perceived stress (all ps < .001) and increased somatic symptoms predicted increased rumination (p ≤ .018). Higher habitual present-moment-awareness was linked to lower premenstrual symptom and impairment levels toward the late luteal phase whereas higher habitual acceptance was associated with lower premenstrual functional impairment (p ≤ .015). Premenstrual symptom increases during the late luteal phase in women with PMS seem to be linked to increased daily rumination and perceived stress. Trait present-moment-awareness and acceptance in turn seem to reflect protective factors against premenstrual distress and may represent useful targets for interventions.

Attention, response inhibition, impulsivity, and decision-making within luteal phase in women with premenstrual dysphoric disorder.

Cognitive impairment is a key feature of depressive disorder. Various forms of cognitive function have yet to be investigated in women with premenstrual dysphoric disorder (PMDD) during early luteal (EL) and late luteal (LL) phases. Therefore, we evaluated response inhibition and attention in PMDD in these two phases. We also examined the associations between cognitive functions, impulsivity, decision-making style, and irritability. There is a total of 63 female participants with PMDD and 53 controls, as determined through psychiatric diagnostic interviewing and a weekly symptoms checklist. The participants completed a Go/No-go task, Dickman's impulsivity inventory, Preference for Intuition and Deliberation scale, and the Buss-Durkee Hostility Inventory: Chinese Version-Short Form at the EL and LL phases. The women with PMDD had poorer attention in the Go trials at the LL phase and poorer response inhibition in the No-go trials at the EL and LL phases. Repeated measures analysis of variance revealed an LL exacerbation of deficit in attention among PMDD group. In addition, impulsivity negatively correlated with response inhibition at the LL phase. Preference for deliberation correlated with attention at the LL phase. Women with PMDD experienced LL declined attention and impaired response inhibition across the luteal phase. Response inhibition is linked to impulsivity. The deficit in attention links preference for deliberation among women with PMDD. These results reveal the different courses in different domains of cognitive impairment in PMDD. Further studies are required to elucidate the mechanism underlying cognitive dysfunction in PMDD.

The Effect of Premenstrual Dysphoric Disorder Diagnosis and Severity on Depression Sensitivity.

ABSTRACT: Premenstrual dysphoric disorder (PMDD) is thought to be associated with depressive disorder. In our study, the depression susceptibility of female patients with PMDD was assessed using the depression sensitivity scale, which is different from previous studies. The study was conducted on 32 PMDD patients aged 18-40 years who applied to the psychiatry outpatient clinic and 30 healthy controls. The mean age of women diagnosed with PMDD was similar ( p = 0.467). The probability of having a family history of PMDD was significantly higher in the PMDD group than in the control group (χ 2 = 11.182, p = 0.001). Previous psychotropic drug use (χ 2 = 8.862, p = 0.003) and family history of mental illness (χ 2 = 5.995, p = 0.014) were significantly higher in PMDD patients compared with the control group. The sociodemographic questionnaire, the Leiden Index of Depression Sensitivity (LEIDS), and the Premenstrual Assessment Form were administered to the participants. No significant difference was found between the patient and healthy groups regarding LEIDS scores ( r = 0.75, p > 0.05). In patients with PMDD, the clinical severity of PMDD was found to increase susceptibility to depression ( r = 0.460, p < 0.01). It was revealed that PMDD severity was associated with susceptibility to depression rather than PMDD diagnosis.

Gender Differences in Premenstrual Syndrome and Premenstrual Dysphoric Disorder Diagnosis and Treatment among Japanese Obstetricians and Gynecologists: A Cross-Sectional Study.

Premenstrual symptoms are characterized by unpleasant psychophysical symptoms that appear during the luteal phase before menstruation and interfere with a woman's quality of life. Premenstrual syndrome (PMS) is a pathological condition with premenstrual symptoms, of which premenstrual dysphoric disorder (PMDD) is a particularly severe psychological symptom. This study aimed to examine the gender differences in the diagnosis and treatment of PMS and PMDD among obstetricians and gynecologists (OB/GYNs) in Japan. Data were obtained from the survey conducted by the Japanese Society of Obstetrics and Gynecology. We used data from 1,257 of the 1,265 OB/GYNs who are engaged in PMS/PMDD practice and reported their gender. Multivariate regression analysis adjusted for propensity scores was performed. Female OB/GYNs were more frequently engaged in treating patients with PMS/PMDD than males [odds ratio (OR) 1.74; 95% confidence interval (CI) 1.36-2.21]. With regard to the diagnostic methods, more female OB/GYNs selected the two-cycle symptom diary than males (OR 2.88; 95% CI 1.80-4.60). Regarding treatment, fewer female OB/GYNs selected selective serotonin reuptake inhibitors as their first-line drug (OR 0.39; 95% CI 0.17-0.89). Gender differences were found in the selection of PMS/PMDD diagnosis and treatment methods among Japanese OB/GYNs.

Limbic self-neuromodulation as a novel treatment option for emotional dysregulation in premenstrual dysphoric disorder (PMDD); a proof-of-concept study.

AIM: To assess the efficacy of a novel neurofeedback (NF) method, targeting limbic activity, to treat emotional dysregulation related to premenstrual dysphoric disorder (PMDD). METHODS: We applied a NF probe targeting limbic activity using a functional magnetic resonance imaging-inspired electroencephalogram model (termed Amyg-EFP-NF) in a double-blind randomized controlled trial. A frontal alpha asymmetry probe (AAS-NF), served as active control. Twenty-seven participants diagnosed with PMDD (mean age = 33.57 years, SD = 5.67) were randomly assigned to Amyg-EFP-NF or AAS-NF interventions with a 2:1 ratio, respectively. The treatment protocol consisted of 11 NF sessions through three menstrual cycles, and a follow-up assessment 3 months thereafter. The primary outcome measure was improvement in the Revised Observer Version of the Premenstrual Tension Syndrome Rating Scale (PMTS-OR). RESULTS: A significant group by time effect was observed for the core symptom subscale of the PMTS-OR, with significant improvement observed at follow-up for the Amyg-EFP group compared with the AAS group [F(1, 15)=4.968, P = 0.042]. This finding was specifically robust for reduction in anger [F(1, 15) = 22.254, P < 0.001]. A significant correlation was found between learning scores and overall improvement in core symptoms (r = 0.514, P = 0.042) suggesting an association between mechanism of change and clinical improvement. CONCLUSION: Our preliminary findings suggest that Amyg-EFP-NF may serve as an affordable and accessible non-invasive treatment option for emotional dysregulation in women suffering from PMDD. Our main limitations were the relatively small number of participants and the lack of a sham-NF placebo arm.

Premenstrual disorders: Premenstrual syndrome and premenstrual dysphoric disorder.

Recently, the term premenstrual disorders (PMDs), which includes premenstrual syndrome and premenstrual dysphoric disorder as a continuum, has been proposed. Although the precise etiology of PMDs remains unknown, the involvement of hormonal fluctuations is clear. The brain transmitters, serotonin and γ-amino butyric acid, also seem to be involved. Serotonin reuptake inhibitors and oral contraceptives are the current mainstay of treatment, but these are insufficient. Even the currently used prospective two-period symptom diary is not widely used in actual clinical practice, creating a major problem of discrepancy between research and clinical practice. In this review, I would like to outline the latest information and problems in the etiology, diagnosis, and treatment of PMDs, with an emphasis on promising new therapies.
