The present invention includes using computer simulation and virtual reality (VR) tests for determining categories of neuropsychological dysfunctions, including executive dysfunctions. A test subject interacts with a computer generated simulated environment according to a predetermined test script.

The present invention includes using computer simulation and virtual reality (VR) tests for determining categories of neuropsychological dysfunctions, including executive dysfunctions. A test subject interacts with a computer generated simulated environment according to a predetermined test script. The test script presents a simulated environment of sight and sound which can closely mirror a real activity, such as daily routines performed by everyone; or an environment such as a game played by the subject. The test script is designed to present situations where subjects with executive dysfunctions will interact and make decisions which indicate the dysfunctions. During the testing, other physiological measurements may be measured and recorded, including subject respiration, heart rate, blood pressure, skin changes etc. The results of the testing are interpreted by scoring the subject's reactions, and provide an indication of the subject's dysfunctioning. These results may be used along with other standardized tests as known in the art, to produce a complete prognosis.
