SYSTEMS AND METHODS TO ASSESS COGNITIVE FUNCTION
Disclosed herein are systems and methods for assessing cognitive function. In an example embodiment, an assessment computer receives demographics data relating to an individual and provides a cognitive assessment test to a portable touchscreen personal computing device, for self administration of the test by the individual. The portable touchscreen personal computing device generates cognitive assessment stimuli, receives responses to the stimuli from the individual via touchscreen activations, measures reaction times of the responses, and transmits the responses and reaction times to the assessment computer for storage in a database. The assessment computer receives cognitive assessment performance data relating to the individual, including the received responses and measured reaction times, and generates performance metrics including at least a cognitive baseline for the individual based at least on the first cognitive assessment performance data.
1 . A method, comprising:
receiving, at a portable computer system, a command to perform a cognitive analysis of a user holding the portable touchscreen computer system;
retrieving, via a processor of the portable computer system from a non-transitory computer-readable storage medium within the portable computer system, a plurality of cognitive tests, the plurality of cognitive tests which, when executed by the portable computer system, allow the user to self-assess cognitive ability, the plurality of cognitive tests comprising:
a visual short-term memory test;
a spatial working memory test; and
a N-back test;
receiving, at the portable computer system, a selection by the user of at least one test of the plurality of cognitive tests;
executing, via the processor, the at least one test;
calculating, via the processor, reaction times for the at least one test;
transmitting, from the portable computer system to an assessment computer, the reaction times and an identifier of the at least one test; and
receiving, at the portable computer system from the assessment computer, a cognitive score of the user for the at least one test.
2 . The method of claim 1 , further comprising:
capturing, via a camera of the portable computer system while the at east one test is being executed, eye motion of the user,
wherein the calculating of the reaction times is based at least in part on the eye motion.
