Abstract:
Background: The clock drawing test is a cognitive assessment tool requiring a person to draw the face of a clock, put in all the numbers, and set the hands to 10 after 11. A modernized approach is the digital clock drawing test (dCDT) which records drawing behaviors 82 times per second. We aimed to: 1) investigate cognitive contributions of three dCDT variables, 2) explore how individuals with mild cognitive impairment (MCI; possible prodromal dementia) differed on these three dCDT variables relative to non-MCI peers. Methods: In this federally funded prospective observational investigation requiring IRB approval and consent, participants completed the dCDT and neuropsychological measurements of processing speed, reasoning, language, and declarative memory. dCDT variables of interest: total clock drawing time(TCT), time in seconds from drawing the clock circle to the next stroke (post clock face latency; PCFL), time in seconds to place the first clock hand (preFHL). Analyses: Correlation and group comparisons. Results: 1) Participants (n=151;age>60). TCT associated with every cognitive domain (r’s=-.452 to -.342,p’s<.001), PCFL with memory and processing speed (r’s=-.258 to- .207,p’s<.013), and preFHL with no domains. 2) MCIs (n=28) were significantly slower in TCT(~10seconds slower;p<0.002), and PCFL(p=0.02). Conclusion: Subtle dCDT behaviors provide meaningful information about cognitive function. ( en )
