Abstract
Minor traumatic brain injury is detected by operating (a) an image generator for presenting a visual stimulus having a predetermined movement across a visual field of a subject and (b) a sensor device for monitoring fast eye movement of the subject while the subject views the stimulus. The sensor device generates a signal encoding the subject's eye position. A computer or microprocessor operatively connected to the sensor device is configured for determining a magnitude for the fast eye velocity component.

A method for detecting minor traumatic brain injury, comprising:
- presenting to a subject a visual stimulus having a predetermined direction and speed of movement across a visual field of the subject;
- monitoring movement of an eye of the subject while the subject views said stimulus, the eye movement including a slow eye velocity component responsive to said predetermined movement, the eye movement further including a fast eye velocity component, the monitoring of eye movement including detecting said fast eye velocity component;
- determining a magnitude of a parameter of the detected fast eye velocity component;
- and comparing the determined magnitude with a predetermined numerical value to determine whether the subject has incurred minor traumatic brain injury.
An apparatus for detecting minor traumatic brain injury, comprising:
- an image generator for presenting a visual stimulus having a predetermined movement across a visual field of a subject;
- a sensor device for monitoring movement of an eye of the subject while the subject views said stimulus, the eye movement including a slow eye velocity component responsive to said predetermined movement, the eye movement further including a fast eye velocity component, said sensor device being configured to generate a signal encoding detected positions of the subject's eye;
- and a computer or microprocessor operatively connected to said sensor device, said computer or microprocessor being configured for determining a magnitude of a parameter of the fast eye velocity component.
