Postpartum psychosis gains attention following Lindsay Clancy murder trial

The high-profile Massachusetts murder trial of Lindsay Clancy, who is charged with killing her three children in 2023, has thrust postpartum psychosis into the national spotlight. While prosecutors argue Clancy planned the killings, her defense claims she was suffering from severe postpartum psychosis. The case has intensified demands from medical experts and advocates to reform maternal mental health care, address widespread diagnostic gaps, and officially recognize the condition as a distinct disorder in the DSM-5.

DSM classification debate

Postpartum mental health care advocacy

• ▪Mental health advocates and doctors are calling for improved postpartum mental health care, increased research funding, and better public education regarding postpartum psychosis.
