BraionOK

Digital Cognitive Assessment Tool Based on Neuropsychological Testing

BrainOK is a smartphone-based cognitive assessment application designed to provide an early screening solution for Mild Cognitive Impairment(MCI) and dementia risk.

It was co-developed by researchers from Seoul National University College of Medicine, neuroengineers, and clinical psychologists. The validity of the tool has been verified through peer-reviewed publications in international journals.
