1. A portable, field-usable immersive cognitive assessment system for testing a cognitive state of an individual by delivery of computer-generated neuropsychological testing, comprising:
- portable headgear, comprising an audio output device and a video output device integrated into the headgear, configured to be worn by the individual to create an environment effective to minimize external audio and visual distractions during the testing, the audio output device providing audible sounds to the individual and including a noise reduction circuit, the video output device comprising a computer display screen mounted to the headgear effective to substantially cover the entire field of view of the individual when worn for administration of neuropsychological testing;
a response selection device that is configured to receive response selections input by the individual in response to a presented neuropsychological test; and
a portable computing device coupled to the headgear and the response selection device and including software that (a) presents a battery of predefined time-limited neuropsychological tests, each test requiring a predetermined response based on what is presented in the test to the individual via at least one of the audio and video output devices of the headgear, (b) receives response selections input by the individual via the response selection device in response to each test of the battery of presented neuropsychological tests, (c) determines a score from each test of the battery of presented neuropsychological tests, and (d) presents the score of the presented neuropsychological tests to a test administrator in real-time after administration of the battery of tests as a measure of a degree of cognitive impairment,wherein the battery of predefined time-limited neuropsychological tests include questions selected from a question bank, the question bank being configured to be modified or enlarged to provide different versions of the predefined time-limited neuropsychological tests.

22. A method for assessing cognitive capabilities of an individual by delivery of a battery of computer-generated neuropsychological tests, comprising the steps of:
-
providing a portable, field-usable computing device for delivering a battery of time-limited computer-generated neuropsychological tests, each of which requires a predetermined response based on what is presented in a test to the individual by way of audible sounds, visual information, or both, and receiving responses to each test of the battery of tests by way of a response selection device actuated by the individual and that is coupled to the computing device; placing portable headgear on the individual in a field environment and administering the neuropsychological test within an environment created by the headgear that is effective to minimize external audio and visual distractions during the test, the portable headgear comprising an audio output device and a video output device coupled to the portable computing device, the audio output device providing audible sounds to the individual and including a noise reduction circuit, the video output device comprising a computer display screen mounted to the headgear effective to substantially cover the entire field of view of the individual; presenting a battery of time-limited predefined computer-generated neuropsychological tests to the individual via the headgear during a predetermined time period, the battery of predefined time-limited neuropsychological tests including questions selected from a question bank, the question bank being configured to be modified or enlarged to provide different versions of the predefined time-limited neuropsychological tests; receiving response selections input by the individual via the response selection device in response to each one of the battery of presented neuropsychological tests; processing via the computing device the response selections of the individual to determine a score from each of the presented neuropsychological tests that scores the cognitive functions of the individual and generates test results that are indicative of a cognitive state of the individual in real-time; and presenting the test results to a test administrator in real-time after administration of the battery of tests as a measure of a degree of cognitive impairment. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
