RT Journal Article SR Electronic T1 Commentary: Postpartum Psychosis, Infanticide, and Insanity—Implications for Forensic Psychiatry JF Journal of the American Academy of Psychiatry and the Law Online JO J Am Acad Psychiatry Law FD American Academy of Psychiatry and the Law SP 326 OP 332 VO 40 IS 3 A1 Susan Hatters Friedman A1 Renée Sorrentino YR 2012 UL http://jaapl.org/content/40/3/326.abstract AB Two dozen nations have infanticide laws that decrease the penalty for mothers who kill their children of up to one year of age. 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.
