A system and method for assessing brain health includes presenting a saccade test to a subject and capturing biological sensor data of the subject in response to the saccade test using a plurality of biological sensors. Saccade cards are employed to measure the brain health of a subject through collection of eye tracking data, for example. Saccade cards using a variety of design elements besides numbers are used for collection of the eye tracking data and other biological data. The captured biological data is used to create a multi-variate signature of the brain health condition of the subject.
