Mental health in the time of polycrisis: geopolitical determinants and modern psychiatry.

Psychiatry is increasingly being practised in environments affected by geopolitical instabilities, including economic fragmentation, democratic backsliding, and widening inequities. The confluence of these phenomena contributes to what has been described as a contemporary polycrisis, encompassing synchronous disruptions that reinforce one another and threaten collective wellbeing. Nevertheless, psychiatric research and clinical work have generally remained oriented towards immediate determinants and risk factors, overlooking the macro-level political and institutional dynamics that can condition stressor exposure and mental health disparities. Amidst, interconnected crises, this paper advances geopsychiatry as a framework for understanding how distal geopolitical determinants translate into psychiatric vulnerabilities across communities and societies. Focussing on armed conflicts, climate change, and forced migration as emblematic domains of polycrisis, it highlights how these compounding phenomena are generating direct mental health burdens and may amplify harms via secondary pathways. Moreover, it contends that the psychiatric consequences of polycrisis are unlikely to be ameliorated through patient-centred interventions alone, but also require innovative approaches responsive to structural inequalities and material forces that transcend borders. In this context, work from geopsychiatry can offer important implications for modern psychiatry, highlighting a need for a more globally representative evidence base, potential clinical adaptations, and policy engagement that better attends to the geopolitical determinants of mental health.
