CogEval is an iPad-based assessment designed to evaluate cognitive function in patients with multiple sclerosis (MS). It provides a two-minute Processing Speed Test (PST) that evaluates cognitive function using elements of attention, psychomotor speed, visual processing and working memory. CogEval is based on, and validated against, the Symbol Digit Modalities Test (SDMT)1. During the two-minute assessment, the patient pairs abstract symbols with numbers, using a key as a guide. Upon completion, the summary, normed data is available for review by healthcare professionals.
CogEval is intended for use in the healthcare setting and is available only to healthcare providers or researchers with responsibility for the management of people with MS. CogEval is reset after each use; the patient information and test results are not stored within the App.
The App is intended for use in the healthcare setting, with MS patients only.
CogEval is supported on iPads 5th generation or later with a screen size of 9.7" (24.6 cm) or greater. iPad minis are not supported.
CogEval version 1.3 is compatible with iOS 13 or greater. CogEval version 1.2 is compatible with iOS 11 and 12. Wi-Fi is required to use AirPrint functionality.
Patient data and results are not saved or stored in CogEval. Results can be manually entered into a patient's health record, and/or printed to an Air-Print enabled printer. After navigating away from the results screen, the results are erased and cannot be viewed again.
Adjusted Z-Scores are based on the raw PST score and on demographic inputs to the application. They are calculated based on a regression model derived from a normative study.
A multi-site normative study enrolled healthy volunteers recruited in the United States, with enrollment for ages 10-89 years inclusive. Adjusted Z-scores are based on a sample size of 270 patients aged 18 years or older. Individuals less than 18 years of age are excluded due to the small pediatric sample size among the 270 health volunteers.
Adjusted Z-Scores are reported only for individuals whose demographic characteristics are within the range of their associated normative study. An adjusted z-score will be shown for patients from 18-89 years of age.
A normative study must be conducted in the reference population of interest. If you are interested in designing, conducting, or sharing results from a normative study in order to develop a normative model, please contact firstname.lastname@example.org.
Your access code is required to view results and to modify the parameters in the Setup screen. Do not share the access code with your patients. If you forget your access code, you can reference the Master Code in the CogEval User Guide in the App. After entering the Master Code, you will be prompted to create a new access code.
Starting in CogEval version 1.3, the App includes a one-time, in-App registration process. You are no longer required to register via the Web and wait for an HCP identifier. Previous registration information was not migrated; therefore, existing CogEval members must re-register.
CogEval is available in most countries in Europe, South America, and North America. There is limited availability of CogEval in Asia, the Middle East, and Africa. If you are interested in using CogEval in your country, please contact email@example.com.
