Confounding Psychosis in the Postpartum Period.

This case report alerts the psychiatric clinician to consider nonpsychiatric etiologies of psychosis appearing during the postpartum period besides postpartum psychosis. The case includes a description of the patient's psychiatric presentation, admission to the inpatient psychiatric unit with subsequent transfer to the medicine department including neuroimaging and neurological consultation. The patient had a remission of psychosis after only two and half days of antipsychotic medication administration. Positive findings on the MRI suggested a demyelinating disease and a 4-month follow up MRI continued to be positive. The etiology was presumed to be a demyelinating disease. In conclusion, psychiatrists need to be alert to include nonpsychiatric pathologies in the differential diagnosis when a patient presents with psychosis in the postpartum period.
