ABSTRACT:
A system for testing a subject for cognitive impairment includes a display, one or more video cameras and a computer. The display presents to the subject multiple stimuli, including a predictable, smoothly moving object, repeatedly moving over a same path. The video cameras sense eye movements of the subject, while the subject visually follows the object on the display. The computer analyzes the subject's eye movements to determine, for example, accuracy and variability of the subject's visual pursuit of the display of the smoothly moving object, and determines, based on the analysis, if the subject has a cognitive impairment. The analysis may provide one or more metrics, such as a metric of attention, a metric of fatigability and a metric of distractibility. The system may also be configured to provide feedback signals to the user, in which case the system also functions as cognition timing and motor training system.
