Perinatal Depression: An Evidence-Based Review of Psychological, Social, and Clinical Approaches to Maternal Mental Health

Abstract

Background: Perinatal depression is one of the most common mental health disorders affecting individuals during pregnancy and the first year after childbirth. It is associated with significant adverse consequences for maternal well being, infant development, family functioning, and overall public health. Despite the availability of effective screening and treatment strategies, many cases remain unrecognized and untreated. Aim: This review aimed to examine the epidemiology, etiology, pathophysiology, clinical manifestations, evaluation, and evidence-based management of perinatal depression, with emphasis on psychological, social, and clinical approaches to maternal mental health. Methods: A comprehensive narrative review of current literature and clinical guidelines was conducted. The review synthesized evidence related to risk factors, biological mechanisms, diagnostic criteria, screening practices, pharmacological interventions, psychotherapeutic approaches, neurosteroid therapies, and emerging treatment modalities for perinatal depression. Results: Perinatal depression was found to result from a complex interaction of hormonal, genetic, neurobiological, psychological, and social factors. Major risk factors included previous psychiatric illness, inadequate social support, obstetric complications, socioeconomic stressors, and family history of mental disorders. Routine screening using validated tools such as the Edinburgh Postnatal Depression Scale facilitates early detection. Effective management includes cognitive behavioral therapy, interpersonal therapy, antidepressant medications, neurosteroid treatments such as brexanolone and zuranolone, and selected nonpharmacological interventions including transcranial magnetic stimulation and electroconvulsive therapy for severe or treatment-resistant cases. Conclusion: Perinatal depression is a multifaceted and potentially debilitating condition that requires early recognition and comprehensive management. Integrated mental health services, timely screening, evidence-based interventions, and improved access to care are essential for optimizing maternal and infant outcomes and reducing the long-term burden of perinatal mental health disorders.
