Is Cognivue just another computerized cognitive test?

The old

Paper-and-pencil cognitive assessment tests have been around for decades. Their structure relies on a simple, question-and-answer format, similar to an educational test. These tests can be used to measure generalized cognition in as little as ten minutes (SLUMS, MMSE, MOCA, etc), or may take several hours and include multiple domain-specific tests (Wisconson card sorting test, Trail making A and B, Stroop color test, etc). The most recognizable dementia specific test is called the ADAS cog, which stands for the Alzheimer’s Disease Assessment scale-cognition. All of theses tests were designed and standardized for use by highly trained neuropsychologists specializing in dementia assessments.

The New

One of the first paper-and-pencil tests to make the switch to a computerized format was the Wisconson Card Sorting Test in the 1990’s. Before automation, considerable burden was placed on the examiner, who must administer the test, provide feedback, and record responses in a fluid, controlled manner that would not effect the results.

Before long, other tests were making the switch to computers, and eventually tablets and phones. The ease of these applications cannot be ignored, but what makes Cognivue, a computerized cognitive assessment tool, any different?

The revolutionary

Paper-and-pencil tests, even ones that have been copied onto computers, focus on a patient’s test taking abilities. They test psychologically, not medically. Cognivue uses an approach that focuses on information processing in the brain, so instead of testing a patient’s performance on an exam, it activates a specific part of the brain and measures the response.

Dr. Charles Duffy, the inventor of Cognivue, also recognized the need for calibration across different abilities. He created two preliminary tests of basic function to measure the individual patients visual and motor capabilities. The test then adapts to that patient. If the patient is doing well the test becomes harder, if they are doing poorly the test becomes easier.

Cognivue is unlike the computerized cognitive tests on the market because it is an adaptive and quantitatively psycho-physical analysis of various brain regions. For more information on the Cognivue test, please visit Cognivue Technology: Bringing Cognitive Care to Primary Care
