Premenstrual tension syndrome

The premenstrual syndrome is discussed in relation to prevalence, symptomatology, severity, and time course. Methodologic problems common to the study of the menstrual cycle are presented. The research on psychologic and physiologic etiologies is reviewed, and results of studies on various treatment modes are discussed. Newer theories suggesting a combined psychophysiologic etiology and concomitant nonpharmaceutical treatment modes encompassing self-care and stress management skills are included.
