Psychotherapeutic and pharmacological treatments of psychiatric disorders during pregnancy are compared as possible treatment options throughout the book. A risk-benefit viewpoint is applied when assessing treatment options. The first chapter presents a review of the multiple changes that occur during pregnancy along with an overview of assessment issues. The second chapter is a review of obstetrics for nonobstetricians. Included are discussions of emotional changes of normal pregnancy and information to distinguish the symptoms of pregnancy from psychiatric symptoms. For example, fatigue and changes in mood, appetite, and sleep are common in normal pregnancy. These symptoms differ from those experienced with depression, in that in pregnancy the low mood is not sustained, and there is not a loss of pleasure. Fatigue responds to rest and, along with appetite changes, may improve as the pregnancy progresses. Normal pregnancy symptoms may have to be distinguished from those of an anxiety disorder because heart rate increase, sweating, nausea, and some hot and cold flashes may be noted in both. Although a pregnant woman may be anxious about her health and that of her child, the anxious thoughts are not generalized, as they are in an anxiety disorder.
