In a nutshell: Georgia Tech researchers have created a tool that allows adults to screen themselves for early signs of dementia. The home-based computer software is patterned after the paper-and-pencil Clock Drawing Test, one of health care’s most commonly used screening exams for cognitive impairment.
Georgia Tech’s ClockMe system eliminates the paper trail and computerizes the test into two main components: the ClockReader Application and the ClockAnalyzer Application. Click here to see a video demo.
ClockReader is the actual test and is taken with a stylus and computer or tablet. The participant is given a specific time and instructed to draw a clock with numbers and the correct minute and hour hands. Once completed, the sketch is emailed to a clinician, who uses the ClockAnalyzer Application to score the test. The software checks for 13 traits. They include correct placement of numbers and hands without extra markings. People with cognitive impairment frequently draw clocks with missing or extra numbers. Digits are sometimes drawn outside of the clock. The time is often incorrect.
