Progressive postpartum depression is one of the least recognized diseases suffered by young mothers despite the fact that almost 80% of women who give birth experience some form of postpartum upset. Although this symptom picture is well described in the research literature, postpartum depression is not recognized in the mental health professional’s legal “bible,” the Diagnostic Statistical Manual of Mental Disorders, fourth edition (“DSM IV”).  The symptoms of postpartum depression may masquerade as manic-depression (bipolar disorder). Periods of euphoria, agitation, sleeplessness, sexual promiscuity, and hyperactivity characterize the manic symptoms. Poor judgment is a result. 
Progressive Postpartum Depression and Psychosis
A common misperception is that the postpartum depression is nothing more than the “baby blues” and will disappear on its own shortly after childbirth.

When this happens, the mother suffers from continued episodes of mania or depression, each one progressively worse than the last. Rejections, separations, and losses often trigger subsequent recurrent episodes. Because of the episodic nature, the woman is often untreated or undiagnosed until a tragedy occurs.
Despite the common misconception that only newborns are at risk from this disease, mothers suffering from the more severe form kill older children. The case of Andrea Yates more than amply illustrates this point.
