1. A neurological screening device for assessing brain dysfunction of a subject, the device comprising:
a projection apparatus configured to project an image onto one or more retinas of one or more eyes of the subject;
one or more detectors configured to capture light reflected from the one or more retinas of the subject, the reflected light indicating a fixation of the one or more eyes; and
a controller configured to:
cause output of a plurality of assessment images on one or more displays of the neurological screening device, the plurality of assessment images corresponding to a cognitive assessment configured to cognitively stress the subject;
generate stressed cognitive performance data corresponding to a cognitive performance of the frontal lobe of the brain of the subject while stressed based at least in part on a presence or absence of the fixation of the one or more eyes during the cognitive assessment; and
determine the brain dysfunction of the subject based at least in part on the stressed cognitive performance data of the frontal lobe.
