The United States does not have such a law, but mentally ill mothers may plead not guilty by reason of insanity. As in other crimes, in addition to the diagnosis of a mental disorder, other factors, such as knowledge of wrongfulness and motive, are critical to the assessment. Postpartum psychosis has been described for 2,000 years and modern science supports a genetic component to the risk. Yet, the Diagnostic and Statistical Manual of Mental Disorders does not include it as a diagnosis, leading to difficulty in testimony. In this article, we discuss postpartum psychosis, infanticide law, and research regarding mothers who kill, and we make recommendations to forensic psychiatrists.
