Differential Diagnosis
Premenstrual syndrome: differs from premenstrual dysphoric disorder in that premenstrual syndrome does not require a minimum of five symptoms nor mood-related symptomatology, and it is generally considered to be less severe than premenstrual dysphoric disorder.
Premenstrual syndrome may be more common than premenstrual dysphoric disorder; its estimated prevalence varies with numbers that hover at about 00%.
While premenstrual syndrome shares the feature of symptom expression during the premenstrual phase of the menstrual cycle, the presence of somatic or behavioral symptoms, without the required affective symptoms, likely meets criteria for premenstrual syndrome and not for premenstrual dysphoric disorder.
