Diagnostic Validity of PMDD: Reexamining Clinical Criteria and Historical Context through an Intersectional Lens

Premenstrual Dysphoric Disorder (PMDD) is a severe and debilitating condition affecting an estimated 3-8% of women and assigned female at birth (AFAB) individuals worldwide. Despite its prevalence, the diagnostic validity of PMDD has been a subject of ongoing debate within the community.

Historical Context of PMDD

The recognition of menstrual-related psychological and physical issues dates back thousands of years. Ancient medical texts, such as the Kahun Gynaecological Papyrus from 1800 BC, describe symptoms like musculoskeletal aches and discomfort during menstruation, attributing them to the movement of the womb. In the 17th century, Thomas Sydenham linked these symptoms to "hysteria," an emotional disturbance. By the late 19th century, Sigmund Freud's theories further entrenched the idea of hysteria, pathologizing the emotional experiences of women and AFAB individuals.

The mid-20th century brought a shift with the discovery of female sex hormones and the coining of "Premenstrual Syndrome" (PMS) by Greene and Dalton, who studied the physical symptoms associated with menstruation. This era marked the beginning of a more scientific understanding of premenstrual conditions, setting the stage for the eventual recognition of PMDD as a distinct clinical entity​.

Clinical Criteria for Diagnosing PMDD

The diagnostic criteria for PMDD, as outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), require the presence of at least five symptoms, including mood swings, irritability, depression, and anxiety, which must occur in the luteal phase of the menstrual cycle and significantly impact daily functioning. These symptoms must be confirmed through prospective daily ratings over at least two menstrual cycles to ensure accuracy​ (BioMed Central)​​ (Oxford University)​.

However, the DSM-5 criteria have faced criticism for their rigid structure and the potential for overlap with other mood disorders. Studies have shown that many women and AFAB individuals with PMDD are often misdiagnosed with conditions such as bipolar disorder, borderline personality disorder, or generalized anxiety disorder. This misdiagnosis can lead to inappropriate treatment and prolonged suffering​ (BioMed Central)​.

Reexamining the Diagnostic Validity

Recent research has called for a reevaluation of the PMDD diagnostic criteria. A study published in Frontiers in Psychiatry emphasizes the need for a more nuanced approach that considers the individual's entire psychosocial context. The study highlights the historical biases in diagnosing PMDD, where psychological symptoms were often dismissed or misattributed due to gender biases​ (Frontiers)​.

Moreover, the research underscores the importance of recognising the comorbidity between PMDD and other mental health disorders. For instance, individuals with a history of childhood adversity may experience more severe PMDD symptoms. Therefore, clinicians are encouraged to conduct comprehensive assessments that include the individual's life history and stressors, rather than relying solely on symptom checklists​ (Frontiers)​​ (IAPMD)​.

The Importance of an Intersectional, Anti-Racist, and Disability-Positive Approach

Incorporating an intersectional, anti-racist, and disability-positive approach in diagnosing PMDD is crucial. Traditional diagnostic criteria often fail to consider the experiences of marginalised communities, including Black, Indigenous, and people of color (BIPOC), as well as transgender and non-binary individuals. These individuals may also suffer from PMDD, yet their symptoms are frequently overlooked due to the gendered and racialised language of the diagnostic criteria.

Healthcare providers should be trained to adopt an inclusive and sensitive approach, ensuring that all individuals, regardless of race, gender identity, or disability status, receive appropriate care. This includes using inclusive language, acknowledging the unique experiences of marginalised individuals, and providing tailored treatment options that respect their identities and lived experiences​ (IAPMD)​​ (BioMed Central)​.

Addressing Racial and Ethnic Disparities: BIPOC individuals often face systemic biases and barriers in healthcare that can lead to underdiagnosis or misdiagnosis of PMDD. Studies have shown that healthcare providers may dismiss or minimize the symptoms of BIPOC patients, attributing them to stress or other socio-environmental factors rather than recognizing PMDD. Additionally, cultural differences in expressing and experiencing symptoms can complicate diagnosis. It is essential to incorporate culturally competent care and to educate providers on recognizing PMDD in diverse populations​ (Frontiers)​​ (IAPMD)​.

Transgender and Non-Binary Considerations: Transgender and non-binary individuals experience unique challenges in accessing appropriate care for PMDD. The gendered language of diagnostic criteria can exclude these individuals, leading to a lack of recognition and treatment of their symptoms. Trans-inclusive healthcare practices, such as using correct pronouns and understanding the impact of gender-affirming treatments on menstrual cycles, are crucial for accurate diagnosis and effective management of PMDD. Providers should be educated on the specific needs of transgender and non-binary patients to offer affirming and competent care​ (IAPMD)​.

Disability-Positive Perspective: Recognising PMDD as a legitimate and disabling condition is vital for validating the experiences of those affected. A disability-positive approach emphasizes the need for accommodations and support, both in healthcare settings and in daily life. This perspective advocates for policies and practices that enable individuals with PMDD to thrive, such as flexible work schedules, mental health support, and comprehensive care plans that address both physical and psychological symptoms. Embracing a disability-positive approach helps to reduce stigma and promotes a more inclusive and supportive environment for all individuals with PMDD​ (Frontiers)​​ (IAPMD)​.

Additional Issues and Challenges

Misdiagnosis and Overlap with Other Conditions: Many individuals with PMDD are initially misdiagnosed with other psychiatric conditions, such as bipolar disorder or major depressive disorder, due to symptom overlap. This misdiagnosis can result in ineffective treatment plans and unnecessary medication side effects. A more precise diagnostic process that distinguishes PMDD from other conditions is essential for effective treatment​ (BioMed Central)​.

Impact on Quality of Life: PMDD significantly affects the quality of life, interfering with personal relationships, work productivity, and overall mental health. The cyclical nature of the symptoms can lead to chronic stress and anxiety, as individuals anticipate the recurring episodes each month​ (Oxford University)​​ (Frontiers)​.

Stigma and Lack of Awareness: Social stigma surrounding menstrual-related disorders often leads to underreporting and delayed diagnosis. Many individuals feel embarrassed to discuss their symptoms openly, which can result in prolonged suffering and lack of appropriate medical intervention. Increased public awareness and education about PMDD are necessary to reduce stigma and promote early diagnosis and treatment​ (American Psychological Association)​​ (IAPMD)​.

Access to Care: Access to specialized care for PMDD is limited, particularly in rural or underserved areas. Many healthcare providers lack training in recognising and treating PMDD, leading to inconsistent and inadequate care. Expanding access to specialized mental health services and improving provider education are critical steps toward better management of PMDD​ (IAPMD)​.

Treatment Challenges: While various treatment options, including hormonal therapies, antidepressants, and lifestyle modifications, can be effective, finding the right treatment plan can be challenging. Each individual's response to treatment varies, and some may experience severe side effects or minimal relief. Ongoing research is needed to develop more targeted and effective treatments for PMDD​ (IAPMD)​.

Moving Forward

Addressing the diagnostic validity of PMDD requires a multifaceted approach. Clinicians must be aware of the historical context and biases that have shaped the understanding of PMDD. They should also embrace a more holistic and inclusive diagnostic process that considers the individual's psychosocial background, race, gender identity, and disability status.

Research efforts must continue to refine the diagnostic criteria, ensuring they are robust and inclusive. Public health strategies should aim to raise awareness about PMDD, reduce stigma, and provide support for those affected. By adopting a comprehensive and intersectional approach, the medical community can improve the diagnosis and treatment of PMDD, ultimately enhancing the quality of life for those affected by this debilitating condition.
