Defining Dysphoric Milk Ejection Reflex: using Premenstrual Dysphoric Disorder as a framework for proposing...

Area of Science:

• Neurobiology
• Psychiatry
• Women's Health

Background:

• Dysphoric Milk Ejection Reflex (D-MER) is a neurobiological condition causing negative mental states during lactation.
• Symptoms are brief, occurring within 5 minutes of milk letdown, with reported prevalence varying from 6-27%.
• D-MER lacks formal classification in DSM or ICD, hindering research.

Purpose of the Study:

• To propose a pathway for classifying D-MER.
• To explore the association between D-MER and Premenstrual Dysphoric Disorder (PMDD).
• To establish a framework for future D-MER research and diagnosis.

Main Methods:

• Review of current D-MER research.
• Comparative analysis with diagnostic criteria for PMDD (DSM-5).
• Exploration of potential hormonal mediation.

Main Results:

• D-MER shares characteristics with PMDD, including heterogeneous symptoms and hormonal influence.
• A classification framework based on DSM-5 criteria for PMDD can be applied to D-MER.
• Formal classification could stimulate further research into D-MER etiology and treatment.

Conclusions:

• Formal classification of D-MER is achievable using frameworks like the DSM-5 criteria for PMDD.
• Establishing diagnostic criteria will facilitate research and differentiate D-MER from other postpartum mood issues.
• Further research is needed to elucidate D-MER pathophysiology and develop targeted interventions.
