UK Launches £80 Million Dementia Challenge to Accelerate Diagnosis Through NHS Testing
The UK government has launched the Dementia Challenge, a new initiative backed by up to £80 million to accelerate the adoption of innovative technologies and practices that diagnose dementia faster and predict how the disease will progress. Nine new technologies, including faster MRI brain scans and a remote cognitive assessment, will undergo real-world testing in the NHS. The goal is for 92% of people to be diagnosed within 18 weeks of a referral, up from around 60% today, with diagnosis often taking more than a year. The program is funded through UK Research and Innovation’s (UKRI) Research and Development Missions Accelerator Programme (R&D MAP) and will only allocate further funding to projects that demonstrate they are working, speeding up the delivery of effective solutions to patients.
Early diagnosis can reduce the likelihood of emergency hospital admissions and delay the need for greater care support, reducing the impact of dementia on NHS services. It may also allow patients to receive treatment sooner and make informed decisions about work, care, finances, and family life. More people die as a consequence of dementia than any other disease in the United Kingdom, accounting for almost one in eight deaths, with over 72,000 people across the UK dying from dementia, including Alzheimer’s disease, in 2025. Dementia is the first condition the UKRI R&D MAP’s Health Mission is focusing on.
UKRI is partnering with industry, academia, the NHS, the Medicines and Healthcare products Regulatory Agency, the National Institute for Health and Care Excellence, the Health Innovation Network, the third sector, and people with lived experience of dementia to deliver the challenge, adopting a fail-fast approach so that only projects showing real promise continue to receive support.
The nine projects selected for real-world NHS testing include work from University College London and the UK Dementia Research Institute to reduce MRI scan times from around 20 minutes to around seven minutes; the University of Exeter’s integration of a digital cognitive health monitoring platform into the NHS; the UK Dementia Research Institute Care Research & Technology Centre at Imperial College London’s home-monitoring platform using unobtrusive sensors and AI; the University of Oxford and Dementias Platform UK’s integration of blood-based dementia biomarkers into routine NHS memory services; Cognitron’s 15-minute remote digital cognitive assessment; the University of Bristol’s routine sleep apnoea screening for memory assessment referrals; Queen Mary University of London’s digital diagnostic tool assessing how the brain processes sound; the University of Cambridge’s AI-enabled clinical decision support tool; and the University of Edinburgh and NHS Research Scotland’s redesign of Scotland’s dementia diagnosis and treatment services.
Science Minister Chris McDonald said dementia is a desperately cruel condition, robbing sufferers of their memories and families of precious time with their loved ones. McDonald noted that science gives hope that this can change, which is why the government is backing projects that can spot the signs earlier, such as tests that look at how people process sounds and speech to identify changes in the brain, and that this work by UK researchers could be transformative in getting people the early treatment they need.
UKRI Health Mission Challenge Director Andy Hill said that by developing better diagnostic and prognostic tools, the program can help people living with dementia understand and manage their symptoms, get earlier access to treatment, and plan for their futures, meaning better lives for people living with dementia and for their families and carers.
Dr Richard Oakley, Associate Director of Research and Innovation at Alzheimer’s Society, said that 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. Oakley noted that 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.
Hilary Evans-Newton CBE, Chief Executive of Alzheimer’s Research UK and Chair of the Dame Barbara Windsor Dementia Goals Programme, said too many families wait more than a year for a dementia diagnosis. Evans-Newton noted that by testing new technologies and backing only those that work, the best innovations can reach the NHS far sooner, and that faster, accurate diagnosis is also essential as new medicines work best early in the disease.
Henry Simmons, Chief Executive of Alzheimer Scotland, said the organization welcomes this investment in innovative approaches to improving dementia diagnosis and is particularly pleased to see Scotland playing a key role through the work of the University of Edinburgh and NHS Research Scotland. Simmons noted that this is an important step towards the high-quality dementia care pathway that people with dementia, their families, and carers deserve.
