The University of Edinburgh has launched a new initiative called the Scottish AI in Neuroimaging to Predict Dementia and Neurodegenerative Disease (SCAN-DAN). The project aims to develop a software tool that can predict an individual's risk of developing dementia by analyzing brain scans from the Scottish population.

The researchers used artificial intelligence (AI) and machine learning (ML) to identify patterns in brain imaging data that could indicate a person's susceptibility to conditions such as Alzheimer's and vascular dementia.
Background
The use of AI and ML in medical research has grown significantly in recent years. These technologies provide powerful tools for analyzing large datasets and uncovering complex patterns that are not easily visible to human researchers. In neuroimaging, these technologies have been particularly useful in examining brain scans, helping to identify biomarkers for various neurological conditions, including dementia.
Analyzing large volumes of brain imaging data to detect subtle patterns holds great potential for enhancing diagnostic accuracy and speed, as well as uncovering new treatment targets. With AI and ML, researchers can uncover insights that may lead to more personalized and effective interventions for those at risk of developing dementia.
About the Project
In this study, the authors detailed the SCAN-DAN project, outlining its goals and methods employed by a team of 20 experts from the Universities of Edinburgh and Dundee. The project involves analyzing a vast dataset of brain scans from patients across Scotland, consisting of 1.6 million images from computed tomography (CT) and magnetic resonance imaging (MRI) scans collected between 2008 and 2018. The SCAN-DAN initiative seeks to develop a digital healthcare tool that radiologists can seamlessly integrate into their routine scanning procedures.
The dataset, approved by the Public Benefit and Privacy Panel for Health and Social Care, part of NHS Scotland, offers valuable insights for researchers. By applying predictive analysis and ML techniques, the team will be able to examine brain scan data and correlate it with health records, with the aim of understanding the factors that contribute to an individual's risk of developing dementia.
Key Findings
Although the SCAN-DAN project is still in its early stages, preliminary results suggest that AI and ML can effectively analyze brain scans to predict dementia risk. The research team has identified several patterns that may indicate a higher risk of dementia. They are also collaborating with Edinburgh Innovations, the University of Edinburgh's commercialization service, to develop the software tool and bring it to market.
The proposed tool for dementia diagnosis and treatment aims to utilize large-scale health data to advance medical research. By combining brain scans with health records, the researchers seek to provide more accurate predictions and personalized treatment plans. By identifying key biomarkers, they hope to enable more precise and targeted treatments for dementia-related conditions such as Alzheimer's and vascular dementia.
This research is part of a broader initiative called Neurology and Digital Science (NEURii), a global collaboration focused on leveraging data, neurology, and digital sciences to improve the quality of life for people with dementia. NEURii provides funding and expertise to projects like SCAN-DAN to develop and launch digital health tools.
Applications
The SCAN-DAN project has broad implications beyond just creating a predictive tool. It has the potential to change how dementia is diagnosed and treated, leading to more effective interventions and better patient care. Once developed, the software tool will help radiologists identify individuals at high risk of dementia and diagnose early stages of related diseases. This early detection could lead to timely interventions, delay disease progression, and improve the quality of life for those with dementia. Integrating the tool into routine radiology could also provide clinicians with valuable insights, accelerating the development of better therapies for Alzheimer’s and other forms of dementia.
Conclusion
In summary, the SCAN-DAN project could be a significant advancement in the field of dementia research. By using large-scale health data and advanced imaging techniques, the researchers aimed to improve the early diagnosis and treatment of dementia. The project's success could pave the way for similar initiatives in other healthcare areas, showing AI's potential to transform medical practice. Its findings could transform how neurodegenerative diseases are diagnosed and treated, leading to earlier detection, more effective interventions, and better patient outcomes.
