Mobile cognitive assessment demonstrates diagnostic equivalence to MMSE and MoCA scales in Alzheimer’s disease screening

The system's core innovations include: (1) A multimodal digital assessment framework that overcomes the environmental limitations of conventional scales; (2) Self-administration capability in non-medical settings; and (3) A dynamic cognitive baseline model to facilitate longitudinal monitoring. mCAS provides a convenient screening solution for early AD detection, with significant potential particularly in resource-limited regions. Future multicenter validation and biomarker integration studies are warranted.
