The digital pandemic in youth: unpacking the algorithmic impact on mental health in an urbanized world

We define the "digital pandemic" as a population-level phenomenon associated with algorithmic pathogenesis, and propose a "Digital Precision Psychiatry" framework that shifts the clinical paradigm from episodic, subjective observation to continuous, objective management. By utilizing digital phenotyping and Just-in-Time Adaptive Interventions (JITAI), this vertically integrated strategy aims to restore bio-psycho-social resilience in youth, turning the digital environment from a source of pathology into a tool for neuroprotection.
