The trial of Lindsay Clancy highlights the tragic consequences of a treatment system poorly built to support people with serious mental illness (SMI) conditions that include psychosis. As facts of the trial become public, it’s increasingly clear that no system of care took responsibility for the totality of this mother’s condition and the safety risks to her family if her worsening symptoms of psychosis weren’t properly managed.
Clancy is accused of killing her three young children in January 2023, before she jumped from their Duxbury, Mass., home’s second‑story window, leaving her permanently paralyzed. Timelines shared publicly indicate that Clancy sought psychiatric care from many places and was briefly hospitalized in the months prior to these events; but her condition was not treated as a medical emergency, even as her psychosis worsened.
The system’s unwillingness to respond to psychosis with the urgency it requires is a problem familiar to TAC, which works to eliminate barriers to SMI treatment. This case is an egregious example of system failures that allowed a tragedy to unfold instead of working proactively to ensure appropriate medical care and family safety.
TAC’s Schizophrenia and Psychosis Resource Center offers information about postpartum psychosis (PPP) and other important facts to know about psychosis signs and symptoms, standards for treatment, linkages to cannabis use, and risks related to untreated psychosis. PPP impacts 1-2 of every 1,000 women who give birth and can occur due to changing hormone levels, psychological and social factors, and immune system activation that occurs during labor, among other things. Tragically, 4-5 percent of women with PPP die by su***de, while 1-4 percent of women with PPP may kill their children.
