Scientists from Edinburgh and Dundee are analyzing brain scans in Scotland to predict dementia risk

A groundbreaking project is underway where scientists are diving deep into brain scans in hopes of predicting dementia risks. This innovative effort, led by a team of 20 experts, aims to create a software tool that could revolutionize early detection of dementia.

AI and Health Records: The Power Duo in Dementia Research

The project involves analyzing hundreds of thousands of CT and MRI scans using artificial intelligence. By combining this with health records, the researchers seek to identify patterns that might indicate a person’s likelihood of developing dementia. The goal is to develop a digital tool that radiologists can use to assess dementia risk and diagnose early stages of related conditions.

Precision Treatments for Dementia in the Works

The team believes that by identifying patients with a high risk of dementia, they can pave the way for more targeted treatments for various types of the condition, including Alzheimer’s disease. This approach could significantly improve the effectiveness of treatments, which are currently expensive, scarce, and often uncertain in their outcomes.

Global Collaboration for a Common Cause

This research is part of a global collaboration called NEURii, which was launched a year ago. The data scientists and clinical researchers from the universities of Edinburgh and Dundee are at the forefront of this initiative. They estimate that they will analyze up to 1.6 million brain images during the project, with the data securely stored in the Scottish National Safe Haven, a platform commissioned by Public Health Scotland for NHS research.

Early Diagnosis: A Key to Better Treatments

Professor Will Whiteley, co-leader of the project from the University of Edinburgh, emphasized that better use of brain scans for predicting dementia will lead to a deeper understanding of the disease. Early diagnosis is crucial, as it can make the development of new treatments easier and more effective.

AI Integration in Routine Radiology

Professor Emanuele Trucco, an AI and medical imaging expert from the University of Dundee, highlighted the potential of this project. If successful, the team will create a suite of software tools that seamlessly integrate with routine radiology practices, helping clinicians flag dementia risks as early as possible.

Voices from the Community: Early Diagnosis Matters

Willy Gilder, a 71-year-old former journalist from Edinburgh, was diagnosed with Alzheimer’s three years ago. He welcomed the project, stressing the importance of early diagnosis. “Knowing your risk can motivate you to make lifestyle changes that improve brain health,” he said. With early detection, patients like Willy can take steps to slow the progression of the disease.

The Urgent Need for Dementia Research

With long waiting lists for diagnosis and relatively low funding for dementia research compared to other diseases like cancer, this project is a crucial step forward. By predicting a person’s risk of dementia, researchers hope to make significant strides in treatment and prevention, offering hope to millions worldwide.
