PREMENSTRUAL SYNDROME. Ozgul Muneyyirci-Delale. Premenstrual Syndrome.
Premenstrual Syndrome (PMS) is defined as “the cyclic recurrence in the luteal phase of the menstrual cycle of a combination of distressing physical, psychological, and/or behavioral changes of sufficient severity to result in deterioration of interpersonal relationships and/or interference with normal activities. Nearly 200 symptoms have been associated with this definition and it is the clustering of these signs and symptoms that is the hallmark of PMS.
The term “catamenial” is derived from the Greek and signifies around menses. In general an instance where a single recognized medical condition presented in the premenstruum was referred to as a catamenial disorder while a cluster of symptoms was referred to as PMS.
Many patients with psychiatric disorders also complain of worsening of their symptoms around the premenstrual phase, called “premenstrual magnification” (PMM).
Milder symptoms are believed to occur in about 30% to 80% of reproductive-age women, while severe symptoms are estimated to occur in 3% to 5% of menstruating women.
The concordance rate (if both twins have PMS) was found to be significantly higher in monozygous twins (93%) than dizygous twins (44%) and in non-twin control women (31%).
