Project description:BACKGROUND:During their reproductive years about 10% of women experience some kind of symptoms before menstruation (PMS) in a degree that affects their quality of life (QOL). Acupuncture and herbal medicine has been a recent favorable therapeutic approach. Thus we aimed to review the effects of acupuncture and herbal medicine in the past decade as a preceding research in order to further investigate the most effective Korean Medicine treatment for PMS/PMDD. METHODS:A systematic literature search was conducted using electronic databases on studies published between 2002 and 2012. Our review included randomized controlled clinical trials (RCTs) of acupuncture and herbal medicine for PMS/PMDD. Interventions include acupuncture or herbal medicine. Clinical information including statistical tests was extracted from the articles and summarized in tabular form or in the text. Study outcomes were presented as the rate of improvement (%) and/or end-of-treatment scores. RESULTS:The search yielded 19 studies. In screening the RCTs, 8 studies in acupuncture and 11 studies in herbal medicine that matched the criteria were identified. Different acupuncture techniques including traditional acupuncture, hand acupuncture and moxibustion, and traditional acupuncture technique with auricular points, have been selected for analysis. In herbal medicine, studies on Vitex Agnus castus, Hypericum perforatum, Xiao yao san, Elsholtzia splendens, Cirsium japonicum, and Gingko biloba L. were identified. Experimental groups with Acupuncture and herbal medicine treatment (all herbal medicine except Cirsium japonicum) had significantly improved results regarding PMS/PMDD. CONCLUSIONS:Limited evidence supports the efficacy of alternative medicinal interventions such as acupuncture and herbal medicine in controlling premenstrual syndrome and premenstrual dysphoric disorder. Acupuncture and herbal medicine treatments for premenstrual syndrome and premenstrual dysphoric disorder showed a 50% or better reduction of symptoms compared to the initial state. In both acupuncture and herbal medical interventions, there have been no serious adverse events reported, proving the safety of the interventions while most of the interventions provided over 50% relief of symptoms associated with PMS/PMDD. Stricter diagnostic criteria may have excluded many participants from some studies. Also, depending on the severity of symptoms, the rate of improvement in the outcomes of the studies may have greatly differed.

Project description:Premenstrual dysphoric disorder (PMDD) is a psychiatric disorder that causes serious impairments in the functioning and quality of life of affected women. Until recently, research efforts were somewhat hampered by the lack of formal diagnostic criteria, which have now been codified as a category in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Better characterization of deficits in socioemotional functioning caused by PMDD may aid in improving treatment efforts. In this investigation, prospective symptom ratings, based on DSM-5 criteria, were used to measure PMDD symptoms in 36 women (18 with PMDD and 18 healthy controls). Two self-report inventories, the Emotion Regulation Questionnaire and the Difficulties in Emotion Regulation Scale, were used to measure ability to regulate emotions, and socioemotional functioning was measured by inventories of social connectedness, perceived stress, and affect. Potential relationships between ability to regulate emotion and PMDD symptom severity, as well as other measures of socioemotional functioning and affective state, were tested. Women with PMDD reported significantly more behavioral impulsivity and greater difficulties in regulating emotion and in socioemotional functioning. Cognitive or behavioral strategies to improve these problems may benefit women with PMDD and help to alleviate distress caused by this disorder.

Project description:Bipolar disorder (BD) and premenstrual dysphoric disorder (PMDD) are two cyclic mood illnesses, sometimes presenting together. Their comorbidity appears to be linked to common biological mechanisms and usually results in more severity of mood symptoms and a poorer long-term outcome. Nevertheless, the management of comorbid PMDD/BD has been scarcely studied. Therefore, the aim of the present paper was to review the published literature on the treatment of comorbid PMDD/BD and to provide point-by-point hypotheses to address these complex clinical cases. We searched PubMed to identify the studies focused on the treatment and management of comorbid PMDD/BD using the following search words, alone and in combination: premenstrual dysphoric disorder, bipolar disorder, comorbid, treatment, management, pharmacotherapy, psychotherapy. The search was conducted on the 1st of June 2019 and yielded 55 records. Four papers met our inclusion/exclusion criteria and were therefore included in our qualitative synthesis. Integrating the few data pertaining to the treatment of comorbid PMDD/BD with the large amount of published data on the two conditions separately, we can suggest that the management of comorbid PMDD/BD needs as a first step to stabilize the bipolar symptoms by means of optimal dosages of mood stabilizers. Then, in euthymic BD patients, the PMDD symptoms could be treated with estroprogestins (first-line treatment). On the contrary, during acute phases of BD, antidepressants (for major depressive episodes) and atypical antipsychotics/hormonal modulators (for manic episodes) could be considered as promising add-on treatments to mood stabilizers. In case of resistant PMDD/BD symptoms, combined strategies should be taken into account, as well as alternative treatments, such as lifestyle changes. In conclusion, RCTs on comorbid PMDD/BD are still lacking. The management of this complex condition is therefore challenging and it requires a tailored treatment.

Project description:BackgroundPremenstrual dysphoric disorder (PMDD) is a mood disorder characterized by psychological and physical symptoms. Differences in white matter have been associated with affective and anxiety disorders, which share some symptoms with PMDD. However, whether white matter structure differs between the brains of individuals with PMDD and healthy controls is not known, nor is its relation to symptom severity.MethodsWe performed tract-based spatial statistics and voxel-based morphometry analyses of diffusion tensor imaging metrics and white matter volume, using 2 neuroimaging data sets (n = 67 and n = 131) and a combined whole-brain and region-of-interest approach. We performed correlation analyses to investigate the relationship between regions with different white matter microstructure and volume and PMDD symptom severity.ResultsWe found greater fractional anisotropy in the left uncinate fasciculus (d = 0.69) in individuals with PMDD compared to controls. Moreover, the volume of the right uncinate fasciculus was higher in individuals with PMDD compared to controls (d = 0.40). As well, the severity of premenstrual depression was positively correlated with fractional anisotropy in the right superior longitudinal fasciculus (r = 0.35).LimitationsIt is challenging to interpret group differences in diffusion tensor imaging metrics in terms of their underlying biophysical properties. The small size of the control group in the diffusion tensor imaging study may have prevented effects of interest from being detected.ConclusionThe findings of the present study provide evidence of differential cerebral white matter structure associated with PMDD and its symptoms.

Project description:AimPremenstrual dysphoric disorder (PMDD) has predictable, cyclic, psychological, and somatic symptoms, such as sleep problems. They result in functional impairment, are aggravated in the late luteal phase of the menstrual cycle, and are resolved by menstruation. The present study evaluated the insomnia, inattention, and fatigue symptoms of PMDD and their fluctuations during the menstrual cycle.MethodsA total of 100 women were diagnosed as having PMDD based on psychiatric interviews and a prospective investigation of three menstrual cycles. A total of 96 individuals without PMDD were recruited as controls. Their symptoms, namely insomnia, inattention, and fatigue as well as functional impairment were assessed by using the premenstrual symptoms screening tool, the Pittsburgh insomnia rating scale, the attention and performance self-assessment scale, and the fatigue-assessment scale during both premenstrual and follicular phases.ResultsIn both the premenstrual and follicular phases, women with PMDD experienced more severe insomnia, inattentiveness, and fatigue than did women in the control group. A paired t-test demonstrated that women with PMDD had more severe severity insomnia, inattentiveness, and fatigue in the luteal phase than in the follicular phase. A repeated-measures analysis of variance demonstrated that the interaction period of PMDD and a menstrual cycle was significantly associated with insomnia, inattentiveness, and fatigue. A further correlation analysis demonstrated that all three symptoms were positively associated with self-reported functional impairment due to PMDD.ConclusionsOur results demonstrated that women with PMDD experienced an exacerbation of insomnia, memory problems, difficulty maintaining focus, and fatigue in the premenstrual phase. These symptoms are correlated with PMDD symptoms severity and functional impairment, and as such, they should be evaluated, and interventions should be employed in the late luteal phase of women with PMDD.

Project description:Serotonin reuptake inhibitors (SRIs) are efficacious treatments for premenstrual dysphoric disorder (PMDD) when given daily or for half of the menstrual cycle during the luteal phase. Preliminary studies suggest that SRI treatment can be shortened to the interval from symptom onset through the beginning of menses.To determine the efficacy of symptom-onset dosing with the SRI sertraline hydrochloride for treatment of PMDD.A double-blind, placebo-controlled, multisite, parallel-group randomized clinical trial conducted September 1, 2007, to February 29, 2012, at 3 university medical centers. In all, 252 women with PMDD started treatment at symptom onset and continued until the first few days of menses for 6 menstrual cycles. Intent-to-treat analyses were performed February 28, 2014, through April 21, 2015.Placebo or sertraline hydrochloride, 50 to 100 mg/d, during the symptomatic interval.Premenstrual Tension Scale (PMTS) score was the primary outcome measure (score range, 0-36; 36 indicates most severe score). Secondary outcome measures included the Inventory of Depressive Symptomatology-Clinician-Rated (IDS-C) (score range, 0-84; 84 indicates most severe score), Daily Record of Severity of Problems (DRSP) (total and subscale scores; higher scores indicate most severe problems), Clinical Global Impression (CGI) scales (score range, 1-7; 7 indicates most severe symptoms and least improvement), and Michelson SSRI (Selective SRI) Withdrawal Symptoms Scale scores (range, 0-51; higher scores indicate more severe withdrawal symptoms).Among the participants, 125 with PMDD were randomized to sertraline, and 127 to placebo. At baseline the mean (SD) PMTS scores for sertaline and placebo were 22.3 (4.8) and 21.4 (4.5), respectively, which declined to 11.7 (6.8) and 12.0 (6.9), respectively; group mean difference, 1.88 (95% CI, 0.01-3.75; P?=?.06). The mean (SD) estimated difference in IDS-C scores between baseline (35.4 [10.7] for sertraline; 32.8 [10.4] for placebo) and the end point (15.3 [10.7] for sertraline; 17.8 [11.0] for placebo) favored the sertraline group by 5.14 (95% CI, 1.97-8.31) points (P?=?.02). Compared with the placebo group, those assigned to sertraline showed greater improvement on the total DRSP score (estimated mean difference, 1.09 [95% CI, 0.96-1.25] points; P?=?.02) and Anger/Irritability DRSP subscale score (1.22 [95% CI,?1.05-1.41] points; P?<?.01) and were more likely to respond to treatment (77 of 115 patients [67.0%] for sertraline and 65 of 124 [52.4%] for placebo; ?21?=?5.23; P?=?.02). The mean (SD) number of symptomatic days before treatment diminished over time (sertraline, -0.7 [3.4] days; placebo, -1.0 [3.2] days), with no group differences in symptomatic days or the Michelson SSRI Withdrawal Symptoms Scale.Depending on the symptom scale, women with PMDD may or may not benefit from SRI treatment during the interval from the onset of premenstrual symptoms through the first few days of menses. Abrupt treatment cessation was not associated with discontinuation symptoms.clinicaltrials.gov Identifier: NCT00536198.

Project description:BackgroundPremenstrual 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.MethodsThis 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.ResultsThis 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.ConclusionsThis 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.

Project description:Ovarian hormones fluctuations across the menstrual cycle are experienced by about 58% of women in their fertile age. Maladaptive brain sensitivity to these changes likely leads to the severe psychological, cognitive, and physical symptoms repeatedly experienced by women with Premenstrual Dysphoric Disorder (PMDD) during the late luteal phase of the menstrual cycle. However, the neuroanatomical correlates of these symptoms are unknown. The relationship between grey matter structure and PMDD symptom severity was delineated using structural magnetic resonance imaging during the late luteal phase of fifty-one women diagnosed with PMDD, combined with Voxel- and Surface-Based Morphometry, as well as subcortical volumetric analyses. A negative correlation was found between depression-related symptoms and grey matter volume of the bilateral amygdala. Moreover, the severity of affective and somatic PMDD symptoms correlated with cortical thickness, gyrification, sulcal depth, and complexity metrics, particularly in the prefrontal, cingulate, and parahippocampal gyri. The present findings provide the first evidence of grey matter morphological characteristics associated with PMDD symptomatology in brain regions expressing ovarian hormone receptors and of relevance to cognitive-affective functions, thus potentially having important implications for understanding how structural brain characteristics relate to PMDD symptomatology.

Project description:BackgroundPremenstrual dysphoric disorder (PMDD), characterized by luteal phase-induced negative affect and loss of impulse control, often results in compromised social interactions. Although amygdala activation is generally linked to negative affect, increased amygdala reactivity to aversive stimuli in the luteal phase has not been consistently reported in PMDD. We tested the hypothesis that amygdala hyper-reactivity in PMDD is symptom specific, rather than generalized, and linked to socially relevant stimuli. Blood oxygenation level dependent signal changes during exposure to negative images with social and non-social content were evaluated in the mid-follicular and late luteal phase of the menstrual cycle. Fourteen women with PMDD and 13 healthy controls participated.ResultsWhen compared with healthy controls, women with PMDD in the luteal phase had enhanced reactivity to social stimuli compared to non-social stimuli in the amygdala and insula, but attenuated reactivity in the anterior cingulate cortex. Functional couplings between emotion processing and controlling areas were significantly different, being positive in women with PMDD and negative in healthy controls. Changes in progesterone levels in women with PMDD correlated positively with altered amygdala reactivity.ConclusionsSocially relevant aversive stimulation elicited enhanced activity in affective processing brain regions that were functionally coupled to compromised activity in cognitive control areas. Because increased reactivity correlated positively with alterations in ovarian steroid levels, data preliminary support the hypothesis that enhanced progesterone sensitivity in PMDD affects corticolimbic processing of social emotions.

Project description:Premenstrual syndrome (PMS) is a common disorder that affects women of reproductive age. It is characterized by periodic mental and somatic symptoms such as irritability, depression, and breast pain during the luteal phase. Premenstrual dysphoric disorder (PMDD) is the most severe form of PMS. In recent years, the incidence of PMS/PMDD has been increasing year after year. However, due to the complex symptoms and ambiguous classification of PMS/PMDD, the limitations of present treatments, such as their poor efficacy rate, have become increasingly apparent. With its unique benefits such as syndrome differentiation and high cure rate, traditional Chinese medicine (TCM) has sparked new diagnosing and treating of PMS/PMDD. This study uses data mining methods, and statistical analysis revealed that Xiaoyao San and Chaihu Shugan San were the commonly used TCM to treat PMS/PMDD. A detailed investigation of regularly used single herbs revealed that most TCM is used as cold herbs that penetrate the liver meridian, with predominant bitter, sweet, and pungent flavors. The network pharmacology method analyzes the interactions between diseases, targets, and herbs. Meanwhile, the deep action targets and molecular mechanisms of 10 commonly used herbs for the treatment of PMS/PMDD are studied, revealing that it involves several ingredients, many targets, and different pathways. This interaction provides insight into the mechanism of action of TCM in the synergistic treatment of PMS/PMDD. It is now clear that we can begin treating PMS/PMDD with TCM using the target and mechanism revealed by the abovementioned findings in the future. This serves as an essential reference for future research and clinical application of TCM in the treatment of PMS/PMDD.
