Researchers from the University of Dundee are building an artificial intelligence (AI) tool which aims to spot early signs of dementia.
A team of 20 researchers from the University of Dundee, along with the University of Edinburgh, have received approval to access a large dataset of brain scans from Scottish patients.
This unique dataset includes 1.6 million CT and MRI images taken between 2008 and 2018. The approval was granted by the Public Benefit and Privacy Panel for Health and Social Care, part of NHS Scotland.
The research team will use artificial intelligence (AI) and machine learning to analyse these images, alongside linked health records, to identify patterns that could indicate a person’s risk of developing dementia. Importantly, the data will be anonymised, ensuring patient privacy.
The ultimate goal is to create a digital healthcare tool that radiologists can use to assess dementia risk during routine scans. Early diagnosis is critical, as it can lead to more effective treatment, particularly for diseases like Alzheimer’s and vascular dementia.
The data will be securely stored in the Scottish National Safe Haven, a platform provided by Public Health Scotland for the research use of NHS data.
Willy Gilder, a 71-year-old former journalist from Edinburgh, was diagnosed with Alzheimer’s in 2021. He emphasised the importance of early diagnosis, stating, "Knowing your risk allows you to make lifestyle changes that can improve brain health. Early diagnosis also makes potential new treatments more effective."
The project, known as SCAN-DAN (Scottish AI in Neuroimaging to predict Dementia and Neurodegenerative Disease), is part of a broader global initiative called NEURii. This collaboration, which includes organisations like Eisai, Gates Ventures, and Health Data Research UK, aims to advance digital health tools for dementia.
Professor Will Whiteley of the University of Edinburgh, co-leading the project, believes that better use of brain scans could lead to earlier dementia diagnosis and improved treatment development. Professor Emanuele Trucco of the University of Dundee added that the project could result in software tools integrated into routine radiology, aiding in the early detection of dementia.
The NEURii collaboration is providing funding and support to ensure the successful development and commercialisation of these digital health tools, with the aim of significantly improving the lives of those at risk of dementia.
