PMS vs. PMDD - Whats' the Difference?

Medical Author: Carolyn Janet Crandall, M.D., FACP

Ms. B.T. is 38 years old. Her co-workers always seem to know when she has her period. During this time, she becomes extremely irritable. She feels guilty because she gets very angry at her children for no logical reason or for apparently trivial reasons. In fact, one of her coworkers, with whom she is quite friendly, suggested she come in before her supervisor noticed problems on the job. She heard that there is a severe version of PMS that requires special treatment. Ms. B.T. wants to know if this is her problem.

Premenstrual syndrome (PMS) has been the term used for mood, and sometimes physical, symptoms that occur cyclically (predictably in relation to menses) in the second half of the menstrual cycle and interfere with a woman's quality of life. Some women experience even more severe symptoms. These women may have a conditions known as premenstrual dysphoric disorder (PMDD).

What is premenstrual syndrome?

Premenstrual syndrome (PMS) is a combination of emotional, physical, psychological, and mood disturbances that occur after a woman's ovulation and typically ending with the onset of her menstrual flow. The most common mood-related symptoms are irritability, depression, crying, oversensitivity, and mood swings with alternating sadness and anger. The most common physical symptoms are fatigue, bloating, breast tenderness (mastalgia), acne, and appetite changes with food cravings.

A more severe form of PMS, known as premenstrual dysphoric disorder (PMDD), also known as late luteal phase dysphoric disorder) occurs in a smaller number of women and leads to significant loss of function because of unusually severe symptoms. The American Psychiatric Association characterizes PMDD as a severe form of PMS in which anger, irritability, and anxiety or tension are especially prominent.

How common is PMS?

About 80% of women experience some premenstrual symptoms. The incidence of true PMS has often been overestimated by including all women who experience any physical or emotional symptoms prior to menstruation. It is estimated that clinically significant PMS (which is moderate to severe in intensity and affects a woman's functioning) occurs in 20% to 30% of women. About 2% to 6% of women are believed to have the more severe variant known as PMDD.

When was PMS discovered?

The mood changes surrounding this condition have been described as early as the time of the ancient Greeks. However, it was not until 1931 that this disorder was officially recognized by the medical community. The term "premenstrual syndrome" was coined in 1953.

What causes PMS?

PMS remains an enigma because of the wide-ranging symptoms and the difficulty in making a firm diagnosis. Several theories have been advanced to explain the cause of PMS. None of these theories have been proven, and specific treatment for PMS still largely lacks a solid scientific basis. Most evidence suggests that PMS results from the alterations in or interactions between the levels of sex hormones and brain chemicals known as neurotransmitters.

PMS does not appear to be specifically associated with any personality factors or specific personality types. Likewise, a number of studies have shown that psychological stress is not related to the severity of PMS.

Premenstrual Syndrome (PMS)

What is a depressive disorder?

Depressive disorders have been with mankind since the beginning of recorded history. In the Bible, King David, as well as Job, suffered from this affliction. Hippocrates referred to depression as melancholia, which literally means black bile. Black bile, along with blood, phlegm, and yellow bile were the four humors (fluids) that described the basic medical physiology theory of that time. Depression, also referred to as clinical depression, has been portrayed in literature and the arts for hundreds of years, but what do we mean today when we refer to a depressive disorder? In the 19th century, depression was seen as an inherited weakness of temperament. In the first half of the 20th century, Freud linked the development of depression to guilt and conflict. John Cheever, the author and a modern sufferer of depressive disorder, wrote of conflict and experiences with his parents as influencing his development of depression.
