Method and associated apparatus for detecting minor traumatic brain injury

摘要

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 parametric value for the fast eye velocity component.

主权项

1. A method for detecting minor traumatic brain injury, comprising:
providing a device including an image generator, a sensor, and a computer or microprocessor; operating said device and particularly said image generator to present to a subject a visual stimulus having a predetermined direction and speed of movement across a visual field of the subject; further operating said device and particularly said sensor to monitor 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; additionally operating said device and particularly said computer or microprocessor to determine a parameter of the detected fast eye velocity component; and also operating said device and particularly said computer or microprocessor to compare the determined parameter with a predetermined reference value to determine whether the subject has incurred minor traumatic brain injury.
