Julia Nardi Riddle explains why postpartum psychosis can produce paranoia and delusions with serious psychiatric risks, even though violence is rare.
The brief
The trial of Lindsay Clancy centers on a stark question: were the killings deliberate acts, or did severe postpartum psychosis leave her unable to understand what she was doing?
Reporter Kristina Rex lays out the prosecution’s control-based argument and the defense’s claim that untreated psychosis and command hallucinations impaired Clancy’s judgment.
The case has widened into a public fight over Massachusetts law, postpartum care, mental-health-system failures, and where responsibility should rest after an unimaginable loss.
Reproductive psychiatrist Julia Nardi Riddle distinguishes postpartum psychosis from the baby blues and postpartum depression, explaining its rarity, biological risks, and treatment.
Riddle’s clearest warning is that paranoia and delusions can create serious risks even when violence is uncommon, making support, education, and urgent care essential.
