This useful little book is both simple and comprehensible to the lay audience for whom it is intended, yet technical enough to be scientifically correct. Such an accomplishment is difficult given the paradoxes, uncertainties, and complexities in this field. The scope of The PMDD Phenomenon is comprehensive and the tone nonjudgmental. The authors "have experienced some form of these disorders" themselves, which makes them sensitive to the predicaments that women encounter in the face of jokes, ignorance, and negative attitudes about premenstrual problems. The book is enriched by extensive quotes from affected women. For example: "It's like having severe sunburn of your emotions." Hypotheses about the causes of premenstrual problems, myths about medication, and drug interactions are reviewed.
