However, they are more likely to be dosed continuously due to SNRI discontinuation syndrome - a flu-like feeling caused by dropping blood levels of SNRI. Anxiolytics
Two medications typically given to reduce acute anxiety have been studied in treatment for PMDD: alprazolam (Xanax) and buspirone. Alprazolam carries a risk of abuse and causes central nervous system depression and results of clinical trials have not shown benefit to treatment. Buspirone showed lower efficacy than SSRI, but may be used as an adjunctive treatment or alternative if SSRI side effects are intolerable to the patient. Psychotherapy
Cognitive behavioral therapy (CBT) has been shown to be effective for reducing premenstrual symptoms in women with (retrospectively-reported) PMS. CBT is an evidence-based approach for treating depression and focuses on the link between mood, thoughts, and actions to help women address current issues and symptoms. When CBT was compared to SSRI alone or in combination with SSRI, groups receiving CBT had significant improvement of PMS symptoms. Through the practice of CBT, women are better able to recognize and modify recurrent issues as well as thought and behavior patterns that interfere with functioning well or that make depressive symptoms worse. However, a recent meta-analysis suggests that existing psychotherapies may be primarily useful for reducing impairment (rather than symptom severity) in PMDD. Hormonal Treatment
Oral contraceptives have been effective in reducing PMS symptoms, but only certain formulations have proven to be modestly effective in the treatment of PMDD.
This is because the result of this polymorphism mimics the hallmarks of PMDD: volatile moods, depression and irritability centered around the menstrual cycle. This gene has been studied extensively in its association with depression and, promisingly for PMDD research, mice homozygous for the BDNF polymorphism exhibited anxiety-like traits that fluctuated and changed around the mices estrus, analogous to the humans menstruation, therefore mimicking some of the symptoms of PMDD. Risk Factors
Environmental stressors have also been found to prospectively increase risk for PMDD symptoms. Environmental components such as stress, hormonal fluctuation, and epigenetics play a key role in the pathology and onset of the disorder. Some studies have noted evidence of interpersonal trauma (domestic violence, physical or emotional trauma, or substance abuse) or seasonal changes (making PMDD potentially comorbid with Seasonal Affective Disorder) having an impact on PMDD risk. But the most common pre-existing disorder found in those diagnosed with PMDD is major depression, wherein they either actually had it or were misdiagnosed when they should have only been diagnosed with PMDD. Finally, an easily modifiable risk factor for PMDD is cigarette smoking. One meta-analysis found dramatically increased risk of developing PMDD in menstruating women who smoke. Relationship to pregnancy and menopause
Women with PMDD usually see their symptoms disappear while they are pregnant. Premenstrual dysphoric disorder is primarily a mood disorder that is associated with onset of menstruation; pregnancy, menopause, and hysterectomies all cause menstruation to cease, thereby stopping the proposed sex steroid-/serotonin-caused symptoms from occurring.
