ViewMind Atlas Cognition

This will be a comparative study in which each subject undergoes testing by certified HCP evaluators administering the and ViewMind AtlasTM evaluation and the MoCA test, as well as additional tests, which are part of a reference standard neurocognitive battery of tests for cognition (WAT-BA, BEM-144, Rey Complex Figure Test, Wechsler Memory Scale subtests, WAIS III subtests, Trail Making Test A and B, Boston Naming Test, Phonological Verbal Fluency test, Semantic Verbal Fluency test, and Clock Drawing Test). Test-retest reliability of ViewMind AtlasTM will be conducted one week after initial testing. Primary Objective: ● To assess the clinical validity of ViewMind Atlas for identifying cognitive impairment, as determined by MoCA Secondary Objectives: * To demonstrate the analytical validity of ViewMind Atlas for measuring cognition (evaluated) against an appropriate reference standard (MoCA) * To examine the discriminant and convergence validity between ViewMind AtlasTM and a battery of neurocognitive tests in identifying cognitively healthy and cognitively impaired test subjects. * To compare the test-retest reliability of ViewMind AtlasTM. * To assess the safety of the ViewMind system. 1. Sensitivity (Se), Specificity (Sp) Negative Predictive Value (NPV), Positive Predictive Value (PPV) positive likelihood ratios, and negative likelihood ratios and Accuracy of ViewMind AtlasTM agreement with the classification of MoCA in identifying cognitively healthy and cognitively impaired test participants. 2. Correlation between the results obtained with ViewMind Atlas™ and the scores of each component of the MoCA test 3. Correlation between the results obtained with ViewMind Atlas™ and the scores of each component of the neurocognitive test battery 4. Regression analysis of test-retest reliability for ViewMind AtlasTM. 5. Collection of adverse events (AEs) Total no. of subjects: 327 * n= 128 for test-retest of ViewMind This study will be conducted in one site: Ramos Mejia Hospital, in Buenos Aires, Argentina. This study is estimated to last 16 weeks, from start of enrollment to final data analysis. All participants will attend at least a single visit during which the cognitive evaluations will be carried out. 128 participants will then come back for a second visit 1-3 weeks after the first visit, to undergo another cognitive evaluation with ViewMind.
