CogEval vs Clock Drawing Test (CDT)

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).  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 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. CogEval is supported on iPads 5th generation of later with a screen size of 9.7" (24.6 cm) or greater on iOS 13 or greater. iPad minis are not supported.

The Clock Drawing Test is a simple tool used to screen for signs of early dementia, including Alzheimer’s disease. The Clock Drawing Test is often used in combination with other screening tests but can be valuable on its own. The early detection of dementia is important since medications exist which can help slow the progression of Alzheimer's disease. The Clock Drawing Test can provide a strong indication of early dementia but cannot diagnose dementia or the type of dementia. In addition to using this app, before making any medical decisions seek a doctor’s advice.
