Demographic-Adjusted Normative Equations for the Oculo-Cognitive Addition Test (OCAT): A Foundation for Individualized Oculo-Cognitive Assessment

Background

Many neurological and cognitive disorders have early oculomotor hallmarks. The Oculo-Cognitive Addition Test (OCAT) is a quick, objective screening tool that measures eye movement and time-based biomarkers of cognitive processing during simple mental addition tasks in under two minutes. Normative values for age, sex, education level, and genetic predisposition to Alzheimer’s disease must be established so cognitively normal populations are not misdiagnosed.
