Validation of the I-UDS Neuropsychological Battery in Patients With Mild Cognitive Impairment and Alzheimer's Disease

The harmonization of procedures for neuropsychological assessment in dementia disorders is essential for the development of shared activities and projects within the IRCCS Network of Neuroscience and Neurorehabilitation (RIN). To this end, a previous project of the network was dedicated to the translation and adaptation of the Uniform Data Set (UDS) neuropsychological battery, following the similar initiative of the National Alzheimer's Coordinating Center (NACC) USA . This project led to the creation of the I-UDS, which can be administered via a tablet application and consists of tests aimed at investigating different cognitive domains, namely memory, attention, language, executive and visuospatial skills. Normative data were obtained from a sample of 433 healthy participants. In order to be able to use the I-UDS battery in clinical and research settings, it is essential to validate its application in patients with neurodegenerative diseases. In particular, in line with the NACC initiative, the battery aims to trace and highlight the continuum between Mild Cognitive Impairment (MCI) and Alzheimer's Disease (AD). The present multicenter study therefore aims to test the I-UDS battery in patients with clinical diagnoses of MCI and AD, in order to explore its ability to differentiate the cognitive profiles of the two groups of patients.
