Premenstrual Dysphoric Disorder (PMDD) Diagnostic Criteria and Treatment

Core Diagnostic Features

• PMDD is characterized by a specific pattern of mood, somatic, and cognitive symptoms that occur during the luteal phase of the menstrual cycle, improve within a few days after menses onset, and become minimal or absent within one week following menses, according to the American Psychiatric Association 1

Symptom Categories

Cognitive Symptoms

• Forgetfulness is a common cognitive symptom of PMDD 1
• Overeating is a neurovegetative symptom of PMDD 1

Temporal Pattern

• The symptoms of PMDD must begin several days before menses onset, start to improve within a few days after menses begins, and become minimal or absent within one week following menses onset 1

Non-Pharmacological Treatment

• Cognitive Behavioral Therapy (CBT) shows positive results in reducing functional impairment, depressed mood, and anxiety in PMDD patients, as recommended by the American College of Obstetricians and Gynecologists 2

Alternative Pharmacological Options

• Hormonal interventions aimed at suppressing ovulation can eliminate premenstrual symptoms, but the benefit-risk ratio must be carefully evaluated, according to the Royal College of Obstetricians and Gynaecologists 3

Diagnosis and Treatment of Premenstrual Dysphoric Disorder (PMDD)

Diagnostic Criteria

• The American Psychiatric Association distinguishes PMDD from other psychiatric disorders, such as Bipolar Disorder, which would show mood episodes lasting days to weeks independent of menstrual cycle timing, not strictly confined to the luteal phase 4

Differential Diagnosis

• Bipolar Disorder can be differentiated from PMDD as it shows mood episodes lasting days to weeks independent of menstrual cycle timing, according to Neuroscience and Biobehavioral Reviews 4

Hormonal Mechanisms in PMDD

Driving Hormonal Changes

• The luteal phase is characterized by progressive increases in estrogen and progesterone levels until mid-luteal phase, followed by a slow decline before menstruation, which may trigger system dysregulation in vulnerable women, according to the American College of Obstetricians and Gynecologists 5, 6
• Women with PMDD demonstrate differential sensitivity to normal gonadal steroid fluctuations, rather than having abnormal hormone levels, as reported by the American Psychological Association 7
• The withdrawal of estrogen and progesterone during the luteal phase is hypothesized to trigger system dysregulation in vulnerable women, as stated by the Annual Review of Clinical Psychology 8

Clinical Implications

• Hormonal interventions that suppress ovulation, such as GnRH analogs, can eliminate premenstrual symptoms by preventing the luteal phase hormonal fluctuations entirely, as recommended by the Endocrine Society 7
