What is digital clock and recall linked with?

Studies link digital clock and recall with 4 measures, among them mini-Mental State Examination score, Montreal Cognitive Assessment score and amyloid PET.

Mini-Mental State Examination score

no changein silico1

1 study

Digital clock and recall predicts mini-Mental State Examination score in silico (held-out test set of Bio-Hermes-001) (RMSE 2.43).
“The machine learning model predicted MMSE scores with a root-mean-squared error (RMSE) of 2.43 in the BH test set.”

Montreal Cognitive Assessment score

upin humans1

1 study

Digital clock and recall is associated with Montreal Cognitive Assessment score in humans (scored in Borderline or Impaired ranges on DCR).
“both agreement rates and correlations were strong between DCR and MOCA components-especially Total Scores comparisons.”

Digital test predicts scores for Alzheimer’s drug eligibility

Prediction error was 2.43 points against measured scores in the test group and 2.62 points in an independent group.Prediction error was 2.43 points against measured scores in the test group and 2.62 points in an independent group.
