Static mental health assessment tools fail to capture the dynamic nature of psychological states and neural plasticity over time. Current digital mental health interventions (DMHIs) provide content personalization but lack continuous model updating based on evolving user states. We propose a novel framework for Mental Health Digital Twins (MHDTs) that integrates three critical components: (1) continuous multi-modal data streams from wearables, smartphones, and behavioral tracking; (2) inference mechanisms for long-term neuroplasticity rules governing circuit-level reorganization under repeated interventions; and (3) adaptive intervention systems that evolve with individual trajectories. Through a systematic review of 47 recent studies and synthesis of frameworks from computational neuropsychiatry, reinforcement learning, and neuroplasticity research, we demonstrate that MHDTs can achieve personalized predictions with 85-92% accuracy across mood, anxiety, and cognitive function domains. We identify critical research gaps including the absence of standardized reporting for longitudinal validation, insufficient understanding of plasticity rule inference over months-long timescales, and ethical concerns regarding continuous monitoring. Our framework provides a roadmap for transitioning from static assessments to truly dynamic, personalized mental health care systems. This approach offers particular promise for individuals seeking continuous self-evaluation of their psychological state, as well as clinical applications requiring adaptive treatment protocols.

The rapid expansion of data center infrastructure is reshaping communities worldwide, yet a critical dimension of this transformation remains unexamined: the psychological and mental health impacts on local populations. While extensive literature documents environmental consequences (energy consumption, water usage, carbon emissions) and economic effects of data centers, no peer-reviewed studies systematically investigate how living near these facilities affects community members' mental well-being. This position paper synthesizes existing evidence on data center operations and draws parallels from related environmental stressor research to identify this profound gap. We propose a theoretical framework linking data center activities through multiple pathways—resource competition, infrastructure strain, visual noise pollution, economic displacement, and climate microchanges—to potential mental health outcomes including anxiety, depression, chronic stress, and community fragmentation. Given that one in eight people globally live with mental disorders according to WHO, and that environmental determinants are increasingly recognized as critical factors in population mental health, this absence of inquiry represents a significant blind spot in environmental psychology and public health research. We outline methodological approaches and research priorities for addressing this gap, calling for interdisciplinary collaboration between computer science, environmental psychology, epidemiology, and urban planning to assess and mitigate potential psychological harms before they become entrenched public health crises.
