A timely warning: Clock drawing errors in young adults and the long-term validity of cognitive screens

Although generally considered robust to demographic factors, the CDT revealed substantial inaccuracies among young adults, likely reflecting reduced familiarity with analogue clocks. These findings reveal the impact that these differences can have on a widely used cognitive screen. Accordingly, they also raise concerns about the long-term validity of the CDT, as expectations may lead to future misclassification in clinical settings.
