Abstract

Clock-drawing tests are simple and rapid screening devices for dementia. It was observed that individuals (" . . .make the clock read 12:45") or an analog prompt (" . . .quarter to 1"), whereas individuals >70 years of age showed improved performance with an analog prompt. The digital prompt has routinely been used to force participants to recode the prompt via conceptualization. Differential scoring across a range of ages has likely derived from the advent and increase of digital clocks with the younger segment of the population. This implies the need for as-yet undetermined alteration in the nature of prompts to force recoding as the current younger population ages.
