The NUCOG is a brief, portable and easy-to-administer cognitive screening instrument developed at the Neuropsychiatry Unit of the Royal Melbourne Hospital, Australia for use in medical, neurologic and psychiatric patient populations, with an emphasis on balancing breadth and brevity, whilst ensuring sensitivity to the subtle changes seen across a range of disorders. These features make the NUCOG ideal for use in a wide range of clinical settings, including office-based health practice, hospitals, and clinic use. The NUCOG combines a thorough coverage of major cognitive domains (attention, memory, language, executive and visuospatial function) with relative brevity and ease of use. Each cognitive domain is scored out of 20 possible points, yielding a maximum NUCOG score of 100. Validated in a variety of psychiatric, neurologic and general medical populations, the NUCOG provides a multidimensional profile of an individual's cognitive status, and takes less than 20 minutes to provide an in-depth assessment of cognitive functioning. An individual's cognitive profile is plotted against normative data means and standard deviations for each domain, allowing the ready visualisation of the pattern of cognitive weaknesses and strengths. The NUCOG is available in English, Spanish, Portuguese, Malay, Turkish, Uyghur and simplified Chinese versions. When integrated with a clinical assessment, this can greatly assist in the diagnosis and management of cognitive disorders and serve as a guide to more in-depth formal neuropsychological testing. The iPad version of the NUCOG allows for drawing directly on the screen, or the utilisation of the iPad's built-in camera, to record patient responses. It also uses the in-built clock of the iPad for timed tests. Results of testing can be printed or emailed in PDF file format. Why use the NUCOG? The NUCOG provides multidimensional scoring, covers areas of cognitive function that other tools neglect (such as executive functioning, spatial memory), is portable and straightforward to use with minimal training. The NUCOG is the ideal tool for use in general medical, neurological, psychiatric and geriatric settings.

*** Important Hardware Note: iPads (2018 and newer models) with 9.7- to 11-inch screens are recommended. Data collected on iPads PRO with 12.9" or iPads Mini with 8.3” screens has not yet been validated. *** NIH Toolbox® V3 is a multidimensional set of performance and person-report measures that assess cognitive, emotional, motor, and sensory function in people ages 3-85, designed for research and clinical use. The original NIH Toolbox was developed by more than 250 scientists over 6 years, and sponsored by the 15 institutes of the National Institutes for Health that make up the NIH Neuroscience Blueprint. This update to the NIH Toolbox® includes streamlined workflows and user interface for over 50 measures, for stand-alone use or as part of a complete assessment battery. With the NIH Toolbox® V3 app, researchers can assess function using a common metric and can “crosswalk” among measures, essential to the process of pooling data and often necessary when a large and diverse sample is needed. With the purchase of this app, you will also have access to select Patient-Reported Outcome Measurement Information System (PROMIS®) tests. NIH Toolbox® does not require a subscription for many features; however, a subscription is required to record assessment responses, and to view and export results. To use all available features of NIH Toolbox®, users must subscribe to a 1-year subscription. Subscriptions are offered for purchase within the app for use on up to 10 iPads. Purchased subscriptions will automatically renew unless auto-renew is turned off at least 24 hours before the end of the current subscription period. Users can enjoy a free trial period to explore the NIH Toolbox V3 app, but data will not be saved and results will not be generated during the free trial. The free trial period will be forfeited when the user purchases a subscription. You may manage your subscription by going to your Apple Account Settings after purchase. Cancellation of the current (paid) subscription is subject to Apple’s discretion. All content needed to administer NIH Toolbox® tests is available in the app, though some tests require additional hardware or materials. Please create a free account at www.NIHToolbox.org to access the NIH Toolbox® V3 Administration Manual, Technical Manuals, supplemental materials, and list of publications. With the purchase of this app, you will immediately have access to tests in the Emotion, Motor, and Sensation domains. Tests in the Cognition domain require the successful completion of a separate approval on www.NIHToolbox.org. This approval process is included in the cost of the subscription; no additional purchase is necessary. Generally, approval will be granted to researchers and clinicians with the knowledge and training to use neuropsychological tests. Contact help@nihtoolbox.org for more details.
