Abstract:

Nodementia.net Project faced the problem of low awareness of dementia among Russians. According to a public survey, 54% of respondents are not afraid of developing dementia; 48% have not even heard that dementia can be prevented or delayed. In order to raise awareness among Russians about dementia and early diagnosis to reduce the risk of occurrence and development of the syndrome, the Nodementia.net project improved the online SAGE-test, which allows everyone to take the test online without leaving their home. The visual-constructive and executive skills tasks in SAGE-test required enhancement of the evaluation algorithm by the AI implementation. In the process of improving the test, project experts explored and compared drawing evaluation services, but none satisfied the criteria. In order to create and train a fundamentally new AI model, experts analyzed more than 10,000 different images, which helped to form the evaluation logic, taking into account the shape of the picture, color, line curvature, accuracy of image repetition and more than 100 other factors. Currently, the AI model correctly evaluates about 80% of images; the next step is 95%. We have improved the mechanism for assessing tasks, reduced biases and increased the amount of users. The AI-technology is designed to highly accurately evaluate human drawings against given criteria and assign scores that correspond to the user's cognitive status.
