The Dementia Challenge will see nine technologies tested in the NHS as part of a UK Government-backed programme designed to speed up dementia diagnosis and improve understanding of how the disease progresses.
The projects, supported by up to £80m through the UK Research and Innovation (UKRI) Research and Development Missions Accelerator Programme (R&D MAP), include faster MRI scans, blood-based biomarkers, remote cognitive assessments, and AI tools.
The programme aims to increase the proportion of people receiving a dementia diagnosis within 18 weeks of referral from around 60% today to 92%.
Some patients currently wait more than a year for a diagnosis, making faster assessment a key focus of the initiative.
What is dementia?
Dementia is a term used to describe a range of conditions that affect cognitive abilities, including memory and thinking.
It can have a significant effect on people’s daily lives and may also increase pressure on health and social care services.
In the UK, dementia affects around 1 million people. An earlier, more accurate dementia diagnosis can help people and their families understand what the condition means for them and make decisions about work, care, finances, and family life.
Earlier diagnosis can also reduce the likelihood of emergency hospital admissions and delay the need for greater care support. For patients who can benefit from treatment, identifying dementia sooner may also allow treatment to begin earlier.
Science Minister Chris McDonald explained: “Dementia is a desperately cruel condition, robbing sufferers of their memories and family of precious time with their loved ones.
“Science gives us the hope that we can change that, which is why we are backing projects that can spot the signs earlier, such as tests which look at how people process sounds and speech to identify changes in the brain.
“This work by brilliant UK researchers could be transformative in getting people the early treatment they need, improving the quality of life for people across our country.”
Nine technologies to be tested in the NHS
The nine projects will now move into real-world NHS testing.
Their progress will determine whether they receive further funding, with continued support focused on projects that demonstrate they can deliver meaningful benefits for patients.
Researchers at University College London and the UK Dementia Research Institute are developing technology to reduce MRI brain scan times from approximately 20 minutes to around seven minutes. The aim is to increase access to diagnostic MRI scans, reduce costs, and improve the patient experience.
At the University of Exeter, researchers are integrating a digital platform into NHS services that lets people monitor changes in their cognitive health and be assessed at the right time.
The UK Dementia Research Institute Care Research & Technology Centre at Imperial College London is developing Minder, a home-monitoring platform using unobtrusive sensors and linked AI. It is intended to support earlier intervention, personalised care and more proactive management.
Researchers at the University of Oxford and Dementias Platform UK are working to introduce a panel of blood-based dementia biomarkers into routine NHS memory services. The biomarkers were validated through the Blood Biomarker Challenge-funded READ-OUT study, which aims to improve diagnostic accuracy.
Cognitron is developing a 15-minute remote digital cognitive assessment designed to make dementia diagnosis faster, more accurate and more accessible.
Meanwhile, researchers at the University of Bristol are introducing routine sleep apnoea screening and improved access to treatment for people referred to memory assessment services. The project aims to improve the accuracy of dementia diagnoses.
AI and digital tools could support earlier detection
At Queen Mary University of London, researchers are developing a digital diagnostic tool that assesses how the brain processes sound using a standard home computer and headphones.
The University of Cambridge is developing an AI-enabled clinical decision support tool that analyses routinely collected information, including medical records, blood tests and cognitive assessments. The system will predict disease progression among people at risk of dementia.
In Scotland, the University of Edinburgh and NHS Research Scotland are redesigning dementia diagnosis and treatment services to provide faster, higher-quality and more consistent diagnosis. The project will also establish ‘living labs’ to test new biomarkers and treatments.
Dr Richard Oakley, Associate Director of Research and Innovation at Alzheimer’s Society, added: “At any one time, one in three people living with dementia in the UK do not have a diagnosis, meaning they are missing out on treatment, support and opportunities to take part in research.
“The Dementia Challenge could be a game changer and shorten the path to diagnosis by testing and rapidly scaling innovative technologies in real NHS settings.
“Alzheimer’s Society is proud to support the Dementia Challenge and help turn promising innovations into real improvements for people affected by dementia.
“Now the Government must match this ambition by introducing a national 18-week target from referral to diagnosis.”
A different approach to research funding
The Dementia Challenge is also transforming how research projects are funded.
UKRI is adopting a “fail-fast” approach, meaning projects must demonstrate progress and meet defined milestones to continue receiving funding.
Rather than awarding a single grant for a long-term project, support will be directed towards technologies that show evidence of potential during testing.
The programme brings together industry, academia, the NHS, the Medicines and Healthcare products Regulatory Agency, NICE, the Health Innovation Network, the third sector, and people with lived experience of dementia.
The aim is to move promising technologies from development into practical NHS use more quickly, while stopping projects that do not demonstrate sufficient progress.
Ultimately, the programme is intended to make dementia diagnosis faster and more accurate, while helping patients and their families better understand what a diagnosis means for their future.
