CogniTwin - digital modeling of patients with cognitive dysfunction Lead Investigator: Todor Kunchev Institution : Sofia University E-Mail : drtodorkunchev@yahoo.co.uk Proposal ID : 1471 Proposal Description: The goal of the project is the development of a digital register for patients with dementia in Bulgaria. The project has the ambition of a nation-wide coverage of dementia cases in the country. The register will be used for epidemiological studies, assessment of dementia care in the country and the formation of strategies for its improvement, as well as scientific research in the field. The aim of the project is to create digital twin models based on big data and machine learning and artificial intelligence methods for exploration of behavioural changes in patients with proven cognitive disorders. Such models will identify the causes and trends that lead to a deepening of the long-term cognitive decline. Their results will be used to assess cognitive status in a timely manner and suggest appropriate preventive actions of cognitive disorders. The project is in its beginning and currently aims to assess the major registers around the world.
