DSM-5 Criteria for Premenstrual Dysphoric Disorder (PMDD)
According to the DSM-5, Premenstrual Dysphoric Disorder (PMDD) is characterized by a pattern of mood symptoms, somatic symptoms, or cognitive symptoms that begin several days before menses, improve within a few days after onset of menses, and become minimal or absent within one week following the onset of menses.
Core Diagnostic Criteria
A. Timing Pattern
- Symptoms must occur in the majority of menstrual cycles
- Symptoms begin in the week before menses, start to improve within a few days after onset of menses, and become minimal or absent in the week following menses 1
B. Symptom Requirements
- At least 5 of the following symptoms must be present:
- Marked affective lability (mood swings, feeling suddenly sad or tearful, increased sensitivity to rejection)
- Marked irritability or anger or increased interpersonal conflicts
- Marked depressed mood, feelings of hopelessness, or self-deprecating thoughts
- Marked anxiety, tension, feelings of being "keyed up" or "on edge"
- Decreased interest in usual activities
- Difficulty in concentration
- Lethargy, easy fatigability, or marked lack of energy
- Marked change in appetite, overeating, or specific food cravings
- Hypersomnia or insomnia
- A sense of being overwhelmed or out of control
- Physical symptoms such as breast tenderness or swelling, joint or muscle pain, bloating, or weight gain
C. Severity and Impairment
- At least one of the symptoms must be from the first four listed (affective symptoms)
- Symptoms must be associated with clinically significant distress or interference with work, school, usual social activities, or relationships 2
- Symptoms must cause functional impairment in social, academic, or occupational domains
D. Exclusion Criteria
- Symptoms are not merely an exacerbation of another disorder
- Symptoms are not attributable to the physiological effects of a substance or another medical condition
- The disturbance is not better explained by another mental disorder
Clinical Assessment Requirements
Prospective Daily Ratings
- Diagnosis requires prospective daily symptom ratings for at least two symptomatic cycles 3, 4
- Retrospective reports alone are insufficient for diagnosis
Most Symptomatic Period
- Research indicates the most symptomatic period typically includes the few days before through the first 3 days of menses 2
- This is important to note when tracking symptoms for diagnosis
Epidemiology and Clinical Significance
- PMDD affects approximately 2-5% of premenopausal women 5
- The disorder is chronic and can significantly impact quality of life
- PMDD was moved from DSM-IV Appendix B ("Criterion Sets and Axes Provided for Further Study") to a full diagnostic category in DSM-5 5
Differential Diagnosis
- Must be distinguished from:
- Premenstrual syndrome (PMS), which is less severe and requires only one distressing symptom 4
- Exacerbation of another mental disorder
- Other medical conditions that may worsen premenstrually
Common Pitfalls in Diagnosis
- Relying solely on retrospective symptom reporting
- Failing to document symptoms prospectively for at least two cycles
- Not distinguishing between normal menstrual changes and clinically significant PMDD
- Missing comorbid conditions that may complicate the clinical picture
- Confusing PMS (milder) with PMDD (more severe, with specific affective symptoms)
PMDD represents a distinct clinical entity with specific diagnostic criteria that must be carefully applied to ensure accurate diagnosis and appropriate treatment planning.
