Quantitative, non-invasive, clinical diagnosis of traumatic brain injury using vog device for neurologic testing

A method of diagnosis of traumatic brain injury comprising the steps of:

• providing a tracking goggle unit coupled to the subject having onboard digital cameras directed to the subjects eyes and onboard display generating stimulus for the subject;
• presenting a plurality of visual stimulus to the subject on the goggle mounted display, wherein each visual stimulus is presented in the eye tracking unit, wherein each visual stimulus provides a target stimulus for a distinct visual based neurologic test;
• obtaining objective physiologic response of the subject from the eye tracking unit based upon each of neurologic test associated with each visual stimulus presented to the subject;
• and
• using the objective physiologic responses to the neurologic tests to diagnose the presence of traumatic brain injury.

A method of screening for mild traumatic brain injury or concussion comprising the steps of:

• providing a head mounted goggle based stimulus generating eye tracking unit to the subject;
• Performing a battery of tests on the subject through the head mounted goggle based stimulus generating eye tracking unit, the testing battery including at least one random saccade test;
• at least one predictive saccade test;
• at least one smooth pursuit test;
• at least one gaze test, at least one anti-saccade test;
• at least one of a subjective vertical or a subjective horizontal test;
• and at least one reaction time test;
• and
• Indicating an increased likelihood of mild traumatic brain injury or concussion based upon abnormal results to this battery of tests.
