There are approximately 5.7 million Americans currently living with Alzheimer’s Disease (AD). Early detection of cognitive impairment allows for earlier treatment, potentially slowing or halting cognitive decline. A 30-min web-camera eye tracking assessment (30-min VPC) has been validated as a tool to predict AD risk. However, a shorter version would allow for greater scalability and improve user experience. The purpose of this study was to: 1) determine the validity of the 5-minute web-camera based VPC test with the 30-min test, 2) determine the test-retest reliability of the 5-min test, 3) compare the 5-minute test scores of cognitively intact adults (18-39 years of age) to the scores of cognitively intact older adults (>65 years of age), 4) examine the relationship between the 5-min web camera based VPC test and additional cognitive tests. This prospective study included two groups, both with normal cognitive function: 24 young adults (26.5 + 7.4 years) and 20 older adults (79.3 + 6.4). Participants were tested on two separate occasions. Trial 1 included the Montreal Cognitive Assessment (MoCA), Digit Symbol Coding, NIH Toolbox Assessment, 30-min VPC, and 5-min VPC. Trial 2 occurred at least 14 days later and participants completed the 5-min VPC, Digit Symbol Coding, NIH Toolbox, and dual-task walking assessments. The 5-min VPC significantly correlated to the 30-min VPC during the first (p = .003) and second (p = .001) trial, and showed significant test re-test reliability (p < .001). The 5-min VPC mean scores were 83% and 80% for Trial 1 and Trial 2, respectively, with a significant time interaction (p = .04). There was a significant relationship between the 5-min VPC and DCCS ( p = .03), MoCA (p = .00), and Digit Symbol Coding (p = .00), during Trial 1. As well as Flanker (p < .01), PCPST (p = .00), PSMT (p < .01), MoCA (p = .00), and Digit Symbol Coding ( p = .00), during Trial 2. The results from this study suggest the 5-min VPC test is a valid and reliable tool to assess cognitive function.
