Postpartum psychosis is an acute mental disorder that occurs after childbirth with a prevalence of 1-2 cases per 1,000 births. The disorder usually occurs suddenly and is a medical emergency that often requires hospitalization and medication. However, in some cases they signal the onset of chronic psychiatric illness. Various studies have shown that postpartum psychosis has a negative effect on the emotional state and daily life of all family members. The aim of the study was to identify the effects of postpartum psychosis on the lives of partners and infants, and how this disease affects the relationship between them and the development of the infant. Data were collected from the databases through the review of the literature published in the last 5 years, (Medline/PubMed, Google Scholar, and Crossref). Based on the collected data on an international level, the main problem in the practical and emotional management of postpartum psychosis by family members is the isolation and lack of knowledge in the treatment of the disease, as there is insufficient information about postpartum psychosis and perinatal mental health disorders in general.
