In this report, we use focus groups and a survey of 2,106 UK adults to investigate the public’s attitudes towards early detection and diagnosis of Alzheimer’s disease, the most common cause of dementia.

Detecting and diagnosing Alzheimer’s disease

Currently Alzheimer’s disease is diagnosed when symptoms appear, but the disease begins damaging the brain years before this point. Research suggests that the ability to pick up Alzheimer’s earlier could transform how and when we treat the disease.

Our findings show a strong appetite among members of the public to find out if they would develop Alzheimer’s. However, most would want tests to be accurate and to give certainty about disease progression. Key findings show:

74% of UK adults would want to know they had Alzheimer’s disease before symptoms appear.

On further questioning, 33% would want to know two years before and 38% would want to know 15 years before.

At least 75% of people would be willing to undertake cognitive tests, brain imaging, blood tests and eye tests if they could help identify their risk of developing the disease.

But survey results showed that only 49% of UK adults were aware that Alzheimer’s disease starts years before symptoms show. And although people could see the benefit of early diagnosis, they were uncomfortable talking about Alzheimer’s.

The report makes a number of recommendations in three key areas:

  1. Improving communication with the public about Alzheimer’s, dementia, and diagnosis.
  2. Supporting earlier detection and diagnosis of Alzheimer’s disease.
  3. Preparing the NHS for future treatments, which may require changes in how and when a diagnosis is made.

This report was jointly developed by Alzheimer’s Research UK and MSD.
