Video Games to Track Cognitive Health

The purpose of this study is to assess cognitive function using a rapid, portable, computerized neurocognitive testing device in a wide variety of clinical settings.

Investigators will recruit participants from public places using the convenience sampling method. Informed consent will be obtain from all participants/parents as well as assent from minors. Participants will be asked to complete a brief yes/no questionnaire before the study begins. Participants will be asked to complete a 10 minute battery of tests consisting of simple video games designed to measure cognitive health. No personally identifiable information will be collected during the tests and all test data will remain anonymous. Data will be stored on servers with HIPAA-level security. No participants will be asked to modify their normal behavior in any way. No feedback or results will be given to participants. The tests will not be distressing in any way. To meet the objective of detecting cognitive impairment, investigators will test a broad array of participants from ages 10 through 99 in several different settings in parallel. The targeted cognitive stressors of advanced age, head injuries, physical strain, sleep deprivation, alcohol ingestion, and marijuana ingestion will be compared to healthy baseline controls. Collectively, these experiments aim to yield an end- deliverable of a rapid, non-invasive, portable piece of software that can be used to detect cognitive impairment. A subset of participants will be asked to take the tests up to three times, so the total testing time is a max of 30 minutes. A subset of participants will be asked simple auxiliary questions, such as "Estimated in minutes, how long was your exercise or workout?". A subset of participants will be asked to wear a FitBit device to monitor their heart rate. A subset of participants will be asked to take a breathalyzer test (BACtrack S80).
