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

Abstract: A device and method for measuring saccadic latency, including a light source positioned within a housing that projects a beam of light through a window of the housing and onto a retina of a subject, lights disposed on or in an external surface of the housing, detectors positioned within the housing and configured to detect light reflected from the retina of the subject through the window of the housing, and a controller that causes output of a sequence of cues and determines a time interval corresponding to a delay between output of a cue in the sequence of cues and either fixation or loss of fixation by the subject, the fixation or loss of fixation being determined based at least in part on the light reflected from the retina of the subject.

Abstract: A device can include a body having a top surface, an opposing bottom surface, a first face and an opposing second face. The first face can have an opening therein. A light source can be positioned within the body. The light source can be configured to create a beam of polarized light. At least a portion of the beam of polarized light can be directed outside of the body through the opening in the front face. At least one polarization sensitive detector can be positioned within the body. At least one light can be positioned on or in the first face. At least one target can be configured to be visible through the opening in the front face of the device. The lights and the target can be configured to illuminate in a predetermined manner or pattern.
