This comparative review examines mental health policies in the United States and various African nations, highlighting the differences in approaches to addressing mental health challenges. The analysis emphasizes the contextual factors that influence policy development and implementation in these regions. In the United States, a comprehensive mental health policy framework has evolved, characterized by federal and state initiatives. Key legislation such as the Mental Health Parity and Addiction Equity Act and the Affordable Care Act have aimed to integrate mental health services into mainstream healthcare, promoting accessibility and reducing stigma. The National Institute of Mental Health (NIMH) plays a crucial role in advancing research and evidence-based interventions. In contrast, African nations exhibit a wide spectrum of mental health policy landscapes, reflecting diverse socioeconomic and cultural contexts. Some countries have made progress in policy development, emphasizing community-based approaches and integration with primary healthcare systems. However, challenges persist, including limited resources, mental health workforce shortages, and stigma associated with mental health conditions. The review explores the role of cultural factors in shaping mental health policies, emphasizing the need for culturally sensitive approaches in African nations. It also highlights disparities in resource allocation and mental health infrastructure between the USA and African countries, contributing to variations in service accessibility and quality of care. The review calls for increased international collaboration, knowledge exchange, and resource mobilization to address mental health disparities between the USA and African nations, fostering a global commitment to holistic mental healthcare. Mental health policies in both regions face common challenges such as stigma, resource constraints, and workforce shortages. Opportunities for improvement include integrating mental health into primary care, leveraging community resources, and utilizing technology to enhance access to mental health services. International collaboration is essential for addressing mental health disparities, promoting a more informed and evidence-based approach to mental health policy development and implementation. The review underscores the importance of ongoing efforts to destigmatize mental health, improve public awareness, and strengthen community support systems.This comparative review examines mental health policies in the United States and various African nations, highlighting the differences in approaches to addressing mental health challenges.
