Medicine's Susan Hatters-Friedman discusses Andrea Yates and postpartum psychosis

A&E: Susan Hatters-Friedman, the Phillip J. Resnick Professor of Forensic Psychiatry at the School of Medicine, emphasized that postpartum psychosis involves hallucinations, delusions and disorganized thinking—and in that state, “we see mothers killing their children.” Andrea Yates’ case turned on whether this psychosis left her unable to know right from wrong when she drowned her five children, ultimately leading to an insanity verdict.
