Learn more about taking part in clinical trials

Despite the growing need for progress in dementia research, just 1% of people who could take part in clinical trials do so.

Increasing public involvement in these studies is essential to advancing our understanding of the diseases that cause dementia – and ultimately creating a world free from the fear, harm and heartbreak of dementia.

Read Alzheimer’s Research UK supporters Marian and Geoff’s story to learn about the experience of taking part in clinical trials.
