Computerized cognitive assessment aid

BrainCheck is a Computerized Cognitive Assessment Aid, a prescription device that uses an individual’s score(s) on a battery of cognitive tasks to provide an interpretation of their current level of cognitive function. It is registered as a Class II medical device with the U.S. Food and Drug Administration (FDA). (Registration number: 3014129043)

BrainCheck is a diagnostic aid used by the clinician, not a stand-alone diagnostic.

Meet recommendations for assessing mild cognitive impairment

In early 2018, the American Academy of Neurology (AAN) released updated guidelines for assessing mild cognitive impairment (MCI). In accordance with the guidelines, a validated assessment tool, such as BrainCheck, should be used in combination with patient and informant reports about cognitive concerns to aid with diagnosis of MCI or dementia.

The BrainCheck assessments


Coordination Test

A proprietary assessment developed by BrainCheck neuroscientists, the Coordination Test measures a person’s static and dynamic balance. In this assessment, a ball is displayed on the screen and moves according to the tilt of the tablet. The patient holds the tablet out in front at arm’s length and tilts it appropriately to keep the ball within the target circle. The test is not difficult with normal coordination abilities; however, with a deficit, it becomes measurably more difficult.

Our scoring algorithm measures the average distance from the target to the ball’s position.

Digit Symbol Substitution

Digital Symbol Substitution is an established assessment for measuring processing speed and accuracy. In this test, the patient must match an arbitrary correspondence of symbols to digits; when presented with a new symbol, they must find, as quickly as possible, the corresponding digit and answer by tapping the digit. This is a continuous performance test in which the patient makes as many correct matches as possible within a fixed testing period.

Our scoring algorithm assesses the number of trials correctly completed in 60 seconds. This assessment is a measure of speed and accuracy of information processing.

Flanker Test

This test presents the patient with a target item (in this case, a central arrow) flanked by congruent or incongruent arrows. The patient must answer which direction the middle arrow is facing as quickly and accurately as possible.

Our scoring algorithm measures the median duration of correct trials on the test. This assessment measures the time needed to respond to stimuli and impulse control.

Stroop Effect

Stroop Effect is an established assessment that measures the reaction time required to overcome cognitive interference.

When the name of a color (e.g., “blue,” “green,” “red,” etc.) is displayed in an incongruent color (e.g., the word “blue” is printed in red), naming the color of the word takes longer and is more prone to errors than when the word and color match.

This assessment measures a patient’s ability to shift cognitive tasks and provides a measure of cognitive inhibition, that is, the ability to inhibit an overlearned response. Our scoring algorithm measures the median duration of incongruent trials.

Trails A

The first part requires the patient to correctly sequence 25 randomly-scattered, numbered circles as quickly as possible. Trails A provides measures of visual search speed, scanning, processing speed, mental flexibility and executive functioning.

Trails B

The second part of the task requires patients to alternate between number and letters (selecting 1, then A, then B, and so on) in the same manner as the first part. Trails B consists of only 24 circles — 12 numbers and 12 letters. Trails B additionally measures the average duration of each trial and efficiency.

Immediate Recall

In the Immediate Recall assessment, 10 words are presented, one at a time, and the patient is given a few moments to memorize each word. The patient is then presented a series of 20 words, including the 10 words that were presented previously. As each word appears, they are to identify if the word appeared previously or not.

Delayed Recall

The Delayed Recall assessment takes place at the very end of the testing battery. Without seeing the original list of words again, the patient must correctly identify the 10 words presented in Immediate Recall, from a list of 20.

Our scoring algorithm measures the percent of correct responses compared to the normative population.
