Evaluation of novel metrics derived from a brief smartphone cognitive task for predicting disease severity in frontotemporal dementia

We tested the use of experimental features derived from a brief two-minute test to distinguish healthy individuals from prodromal or symptomatic FTD. Classification accuracies were moderate to high, suggesting that while traditional measures continue to perform well, novel features provide an improvement in accuracy. Future directions include analogous investigations of other smartphone cognitive tasks collected through this battery.
