PREMENSTRUAL DISORDERS
PREMENSTRUAL SYNDROME
A   36-year-old patient complains   of  depression, anxiety,    irritability,   and
breast  tenderness, which   occur   on  a   monthly basis.  On  further questioning,
the symptoms    most    commonly    occur   two weeks   before  her menstruation
and disappear   with    menses.Premenstrual    syndrome    (PMS)   (5% of  adult   women)  includes    a   wide    range   of
physical    and emotional   difficulties,   as  well    as  the more    severe  affective   changes
included    in  premenstrual    dysphoric   disorder    (PMDD). The basis   for diagnosis   is
a   symptom diary   that    the patient keeps   throughout  three   menstrual   cycles. The
specific    symptoms    are less    important   than    their   temporal    relationship    to  the
menstrual   cycle.  All of  the following   must    be  present:
Must    be  recurrent   in  at  least   three   consecutive cycles
Must    be  absent  in  the preovulatory    phase   of  the menstrual   cycle
Must    be  present in  the two postovulatory   weeks
Must    interfere   with    normal  functioning
Must    resolve with    onset   of  menses
