Age and Graphomotor Decision Making Assessed with the Digital Clock Drawing Test: The Framingham Heart Study

摘要: Background Digital Clock Drawing Test (dCDT) technology enables the examination of detailed neurocognitive behavior as unfolds in real time; a capability that cannot be obtained using traditional pen and paper testing format. Objective Parameters from dCDT were used to investigate constructs related higher-order decision making information processing speed. The current research sought determine effect age combined motor non-motor components drawing, latencies. Methods A large group stroke- dementia- free Framingham Heart Study participants administered command copy with hands set for "10 after 11". Six groups (age range 28-98) constructed. Results Differences between found total time completion, stroke count, latencies both test conditions. Conclusion Longer age-related may reflect greater need working memory increased self-monitoring older subjects. These latency measures have potential serve biomarkers Alzheimer's disease other insidious neurodegenerative disorders.
