Abstract
Premenstrual disorders negatively impact the quality of life and functional ability of millions of women. The two generally recognized premenstrual disorders are premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD). These disorders are characterized by a wide variety of nonspecific mood, somatic and behavioral symptoms that occur only during the late luteal phase of a woman's cycle and disappear soon after the onset of menstruation. This paper reviews the diagnostic criteria for PMS and PMDD, describes some of the more common symptom diaries and other tools used to diagnose premenstrual disorders, and discusses the challenges inherent in diagnosing PMS and PMDD. A survey of peer-reviewed articles and relevant texts provided diagnostic criteria, descriptions of diagnostic tools and information about diagnostic challenges. The many nonspecific symptoms associated with premenstrual disorders complicate the diagnostic process. The use of proven symptom diaries and other diagnostic tools should aid in the differential diagnosis of premenstrual disorders. Patients need to report bothersome premenstrual symptoms, and clinicians should become more proficient in the diagnostic process in order to prevent underdiagnosis of these disorders.
