Leveraging digital health and artificial intelligence to mitigate social isolation and mental health

Concurrent advances in digital health technologies have offered promising tools for mitigating these challenges. Digital interventions range from information and communication technologies (ICT) to artificial intelligence (AI)-enabled applications that facilitate social connection, remote health monitoring, and psychosocial support. There is an urgent need to synthesise current evidence and critically evaluate the methodological and implementation gaps that limit the effectiveness and scalability of these technologies. This Commentary aims to assess recent literature on digital and AI-driven approaches to reducing social isolation and improving mental health in older adults, identify limitations in current research, and propose directions for future work that are both evidence-based and implementable.
