Why Dementia Research Matters

Sir Simon Lovestone
Professor of Translational Neuroscience, University of Oxford Department of Psychiatry

"Dementia has to be one of the most exciting and important areas of research today. Challenging, certainly, but we are surely on the cusp of major advances and there can be no better area for researchers to launch a career and one that has the potential to impact on huge numbers of people around the world."

Gill Livingstone
Professor of Psychiatry of Older People, University College London Division of Psychiatry

“Dementia is the most important health, social and economic challenge of our time. Now is the time to develop the most talented people in their early career as dementia researchers so they can build on the progress that has begun. These researchers will make a difference to those many people living and dying with dementia and their families and in doing so can transform the future for us all.”


Prof Sebastian Crutch
Neuropsychologist, Dementia Research Centre, UCL Institute of Neurology

"Although awareness of the dementias is on the rise, there is still much that researchers and their work can contribute to challenging traditional definitions and common misconceptions. A particularly exciting opportunity is to work not just for but with people living with or caring for someone with a dementia, who so often inspire, train and develop the thinking of creative researchers."

Prof Bob Woods, Professor of Clinical Psychology of Older People, Bangor University

“One of the most exciting developments in dementia research is the engagement of people living with dementia and their family care-givers. Whatever your area of research – from care to cause or cure – their involvement keeps you grounded in the real-life difficulties faced by those affected by the condition and their courage and creative ways of coping never fail to inspire and motivate. We urgently need to increase capacity in my own area of psychosocial research – improving care today and tomorrow is vital for the millions of people living with dementia across the world.” 

Professor Charlotte Clarke, Head of the School of Health in Social Science, University of Edinburgh

Tackling the challenges of dementia in society needs fresh ideas, newly applied theory and innovative methods – and so it needs early career researchers working in research-rich environments that nurture careers.

Why Choose a Career in Dementia Research?

Careers in dementia research are often described as a calling, we want you to know that Dementia Research Matters. That can make the work sound more heroic, and perhaps more intimidating, than it needs to be. Most researchers do not arrive with a grand plan to change the world. They start with a question, an interest or an experience that makes them want to understand something better.

There is certainly no shortage of questions.

According to the World Health Organization, 57 million people were living with dementia worldwide in 2021, with nearly 10 million new cases each year. More than 60% live in low- and middle-income countries, and the global number is expected to reach 139 million by 2050.

Those figures explain why the research matters, but they do not tell the whole story. Every number represents a person trying to get a diagnosis, carry on working, remain independent or find the right support. Around them are families, friends, health professionals and care services trying to do the same.

Dementia research is also much broader than many people assume. It is not just scientists in laboratories searching for a cure for Alzheimer’s disease.

A dementia researcher might spend the day studying cells, analysing brain scans, running a clinical trial or working with genetic data. Another might be investigating how to improve diagnosis in primary care, designing technology for people with memory problems, studying inequalities in access to services or finding better ways to support unpaid carers.

There are roles for neuroscientists, psychologists, nurses, doctors, social care researchers, statisticians, engineers, economists, designers, occupational therapists, physiotherapists and many others. Dementia can be caused by several different diseases, and its effects reach into almost every part of life. No single profession or academic discipline is going to provide all the answers.

There has been genuine progress. The first disease-modifying treatments have shown that it is possible to slow the progression of Alzheimer’s disease for some people in its early stages. That is important, but it needs to be kept in perspective. The benefits are modest, the treatments carry risks, access remains limited and they are not suitable for everyone. There is still no cure, and effective treatments are needed for the many other diseases that cause dementia.

Treatment is only one part of the picture. Updated WHO guidance published in 2026 suggests that action on potentially modifiable factors could prevent or delay up to 45% of dementia risk. That opens up important research questions about cardiovascular health, hearing, education, social isolation, air pollution and inequality. Some of the answers will come from medicine. Others will require changes to services, communities and public policy.

Better care and support matter just as much. They are not consolation prizes while everyone waits for a cure. Research can help people receive an earlier and more accurate diagnosis, stay independent for longer, manage symptoms, access suitable services and have more control over decisions about their lives.

The best work is done with people affected by dementia, not simply about them. People living with dementia and their families can help decide which questions deserve attention, whether a study is practical and whether its findings are likely to make any difference outside a journal article. That involvement usually makes the research better.

None of this makes dementia research an easy career. Experiments fail, participant recruitment runs late, datasets refuse to behave and funding is competitive. Progress can be slow, and the answer to one question often creates another five.

But the work is varied, collaborative and useful. It offers the chance to tackle problems that matter while working alongside people with very different skills and experiences.

It does not need to be a calling or a lifelong mission, but Dementia Research Matters, and you can help! It can simply be a fascinating career spent asking worthwhile questions and trying to make life better for people affected by dementia. That is reason enough to consider it.
