Abstract: Background:Detecting the beginning of cognitive decay is crucial to guarantee good management and the possible prevention of dementia progression. The present study arises from observations collected during an educational event to promote mental and physical health in which incidental neuropsychological data gathered on 290 citizens showed the importance of routine neuropsychological examination in detecting early signs of cognitive decay, since many individuals were unaware of the decrease in their cognitive efficiency. Accordingly, the availability of a screening tool that is computerized, portable, self-administrable, and sensitive to the main neurocognitive changes testifying the progression towards pathological aging is critical. Objective:To this aim, we developed a computerized battery for the early, preclinical Diagnosis of Neurocognitive disease (DiaNe), that can be self-administered and performed autonomously by using a tablet. Methods:DiaNe includes tests expected to evaluate the main cognitive domains involved in neurodegenerative diseases (memory, attention, executive functions) with a detailed assessment of visuospatial memory in particular. Results:DiaNe is not just the translation of standard tests into telematics, rather it is a new tool that provides both accuracy and response time measurements, aimed to screen cognitive profile and monitor it over time, being able to detect changes in still normal performances that may be suggestive of an ongoing onset of neurocognitive disorders. Conclusion:Here we present an investigation of DiaNe concurrent validity showing that its results are comparable to those obtained by existing paper-and-pencil neuropsychological tests, and propose that DiaNe could be a useful, quick, and economical instrument for the monitoring of cognitive aging.
