The Visual synchronization task (VST) evaluates the motor control function, generates evaluation parameters, and takes only 25 seconds to complete. Evaluation parameters of the VST were tested as predictors of mild cognitive impairment (MCI) and dementia. The mean rotation speed parameter decreased in order of control, MCI, and dementia groups. With the mean rotation speed parameters of right hand in the first period (represented as AveP3rR1), p-value of t-test between the control group and the dementia group is 8.37 × 10-13, and AUC is 0.863. Between the control and dementia groups with 0.765 as a cut-off value of the AveP3rR1, specificity is 0.84 and sensitivity is 0.77. Using the mean rotation speed of the right hand in the first period as the evaluating parameter, the VST can be measured in less than 15 seconds, which enables an easy screening for MCI.
