Patent ID: 8475391

Claim:
A method to evaluate functional impairment in a brain of a subject, said method comprising the steps of: performing a spatial distractor tasks test, said spatial distractor tasks test assessing the combination of visual motion and visual form, said spatial distractor task test comprising the following steps executed on a processor: presenting at least one scene to said subject on a display, said scene comprising a plurality of elements and a background; modulating the saliency of a predetermined section of said scene; receiving feedback from said subject, said feedback associated with input device; superimposing at least one additional cue onto said scene, said additional cue associated with at least one distractor; generating a shift in attention of said subject from said predetermined section to said distractor; receiving refined feedback from said subject via at least one input device; quantitatively refining said refined feedback relative to said scene; adjusting the motion associated with said scene relative to accuracy of said quantitatively refined feedback, said adjusted motion associated with a predetermined target; calculating a critical threshold parameter for said subject; recording said critical threshold parameter onto a tangible computer readable medium; and using said critical threshold parameter in assessing evaluating or determining at least one functional impairment in a brain of said subject.
