Here's an ingenious way to spot a concussion: stick the victim's head in a VR rig and then measure any difficulties s/he has with reaction times, resolving stereo effects, and so forth.
The wearer sees groups of words, flashing white squares that change positions, and a series of shapes with different colours and patterns. At the same time, instructions are flashed up on the VR display while verbal commands are given through the headphones. The wearer responds to the commands by pressing one of two buttons on the controller.
By measuring reactions times in a battery of tests, the system is designed to detect even mild cognitive deficits associated with concussion or early dementia. DETECT completes its tests in about 7 minutes. Conventional cognitive tests require hours of testing and trained personnel to administer them, and score and interpret the results.
