Menstrually related disorders--towards interdisciplinary international diagnostic criteria

Premenstrual and catamenial disorders are prevalent, diversified and involve various body systems. The mechanisms and management of the menstrually related disorders (MRDs) are hampered by a fragmented approach because each cluster of symptoms is studied and treated by specialists in a number of related disciplines. The apparent common denominator of MRDs, an association with the menstrual cycle, also carries with it associations with ovulation and ovulation-related hormonal and cyclic biological changes. To achieve progress in understanding and treating MRD, an interdisciplinary nomenclature and diagnostic system are needed. Criteria based on temporal occurrences and not on phenomenology have been developed after interdisciplinary discussions and are herein proposed.
