The article analyzes the impact of the COVID-19 pandemic on the mental health of the population, with a focus on long-term consequences. Key factors affecting the mental condition of various demographic groups are examined, including social isolation, economic instability, future uncertainty, and information overload. The importance of studying adaptation mechanisms is emphasized, including the development of resilience, the role of social support, and the extensive use of telemedicine technologies to ensure access to psychological assistance during the crisis. Digital tools have partially compensated for the limitations of traditional forms of psychiatric care. However, limitations have been identified, particularly among older adults, due to insufficient digital literacy. The formation of sustainable resilience mechanisms and active use of social support play a key role in minimizing the negative effects of the pandemic. Special attention is given to the need to strengthen national healthcare systems, expand access to psychiatric care, and address existing barriers to improve the mental health of the population in the post-pandemic period. © 2025 Elsevier B.V., All rights reserved.
