New York Times References MGHP3 in Coverage of Postpartum Psychosis and the DSM

Dr. Lee S. Cohen, Principal Investigator of the MGHP3 study, was quoted in a New York Times article on 1/21/2026 about the absence of postpartum psychosis from the Diagnostic and Statistical Manual of Mental Disorders (DSM).

From the article:

“‘Do I think that there are patients who have postpartum psychosis who do not necessarily meet the criteria for bipolar disorder? Yes,’ said Dr. Lee Cohen, who directs the center for women’s health at Massachusetts General Hospital and leads the country’s largest postpartum psychosis study.

‘Do I think it’s the end of the world if it falls in the bipolar section of the D.S.M.?’ he continued. ‘I think I’m way more concerned about it not getting in than it being not a perfect fit.’”

The article also references MGHP3's 2024 paper “The Phenomenology of Postpartum Psychosis: Preliminary Findings from the Massachusetts General Hospital Postpartum Psychosis Project." Read more here.”
