The study cites the case of a 27-year-old physician who experienced a normal delivery and gave birth to a full-term baby boy. But within two days of the birth, she told her husband that she believed he was poisoning the baby's food, and that the baby was "staring at her strangely," according to the study. The woman also reportedly "thought she smelled horses and heard them galloping through her bedroom."
She had sleep disturbances, did not bathe and gazed out the window for hours without explanation, according to her husband. She also heard voices that commanded her to go with her infant son and jump in front of a subway train.
While treatable, postpartum psychosis is not curable.
"If the boyfriend or family had been involved and there was no stigma or confidentiality issues, all would have been in the open and she would have gotten treatment," Galynker said of Carey. "None of this would have happened."
Stamford police tried numerous times to intervene in Carey's increasingly manic behavior, according to reports.
In December, police offered to assist her with the baby, but said Carey told them that they would have to tackle her on live television in order to take her to the hospital.
They then forcibly took the baby and handcuffed Carey, but she managed to slip out of one of the cuffs, according to reports. After a brief struggle she was recuffed and transported for a mental health evaluation.
The next day, according to sources, her boyfriend took her to the hospital for the evaluation and she was prescribed the drug Ambien, because she was having trouble sleeping.
Last Dec. 21, police were called after Carey had driven to Brooklyn with her daughter to attend a family party. The next day, when she returned to Stamford and was off her medication, according to sources, she tried to pick a fight with her boyfriend. Police were called to her home, and Carey became combative, injuring an officer, before she was transported again to the hospital, according to sources.
Later that month in a follow-up visit to the hospital, Carey's boyfriend told a social worker that Carey had suffered from postpartum depression, and he expressed concern that she was not eating well. By January, though, the boyfriend reported that she was doing well and was back to normal.
Days later, Carey told the social worker that before her initial hospitalization she felt restless, tired, delusional and had difficulty sleeping. She told the social worker that doctors at Stamford Hospital confirmed she had postpartum depression after her initial hospitalization.
