Background Perinatal depression is a common mental health disorder which spans during and after pregnancy. Unfortunately, there is poor healthcare-seeking behaviour for this treatable condition. Additionally, maternal healthcare workers sometimes overlook the signs and symptoms, failing to diagnose it adequately. This review aims to provide a framework for understanding the in-depth perceptions and implementation gaps surrounding perinatal depression in Nigeria. Methods This study employed a rigorous qualitative evidence synthesis methodology to gather and analyse both published and unpublished qualitative research on the lived experiences and perceptions of perinatal depression in Nigeria. The research was conducted by searching multiple electronic databases, citation chaining, and checking reference lists. The studies were then screened by title, abstract, and full text, and the quality of the included studies was evaluated using the Critical Appraisal Skills Programme (CASP) checklist for appraising a qualitative study. The data extracted from these studies were then synthesized using the ‘best-fit’ framework method, which combines deductive and inductive approaches to analysis. Results 10 eligible papers were identified. Data were organised into themes eight themes mapped to an already existing framework: Recognitions of perinatal mental distress, labelling of mental distress, symptom patterns, social norms, roles and expectations, supernatural factors, physical/bodily issues, coping strategies, help-seeking from professionals/medical institutions. No study was excluded as a result of methodological limitations. Conclusions The review highlights the significance of integrating mental health services into routine perinatal care and the need for comprehensive interventions that consider sociocultural factors. The findings emphasize the importance of increasing awareness and education among women and healthcare providers to improve early detection and intervention. Healthcare professionals play a crucial role in identifying and managing perinatal depression; therefore, it is essential to provide them with comprehensive and regular training.
