AI to Analyze 1.6M Brain Scans for Dementia Risk Prediction Tool

A team of scientists is set to analyze over 1.6 million brain scans using artificial intelligence, aiming to develop a tool that predicts an individual's risk of dementia. This ambitious project is a collaborative effort between researchers at the University of Edinburgh and the University of Dundee, as part of the global research initiative NEURii.

AI-Driven Analysis of Brain Scans

The research will involve examining CT and MRI scans of patients from Scotland, collected over more than a decade. The scientists will leverage AI and machine learning to match these images with linked health records, searching for patterns that could help doctors assess dementia risk more accurately.

Global Dementia Crisis

The urgency of this research is underscored by the alarming projections for dementia worldwide. The number of people living with the condition is expected to nearly triple to 153 million by 2050, posing a significant challenge to health and social care systems. Currently, the global costs associated with dementia exceed $1 trillion annually.

Development of Diagnostic Tools

The primary goal of the researchers is to create digital tools that radiologists can use during patient scans to determine the risk of dementia. These tools could facilitate earlier diagnosis of the disease and related conditions, as well as accelerate the development of more targeted treatments.

Expert Insights and Future Prospects

Professor Emanuele Trucco, a specialist in AI and medical imaging at Dundee, emphasized the potential impact of this new dataset on neurological research. He highlighted that if a successful proof of concept is established, the resulting software tools could seamlessly integrate into routine radiology, aiding clinical decision-making and early detection of dementia risk.

Data Security and Ethical Considerations

The analysis will involve up to 1.6 million images, with the necessary approvals from the public benefit and privacy panel for health and social care under NHS Scotland. The data will be securely stored in the Scottish National Safe Haven, managed by Public Health Scotland, ensuring its use in research is both safe and ethical.

Paving the Way for New Treatments

Professor Will Whiteley, co-leader of the project from Edinburgh’s Centre for Clinical Brain Sciences, stressed the potential benefits of improved brain scan utilization in dementia prediction. He pointed out that better understanding and earlier diagnosis could significantly advance the development of new treatments, which are currently expensive, limited, and of uncertain effectiveness.
