Dementia Explained has been developed by Alzheimer’s Research UK to help children and teenagers understand dementia, how it affects someone and how this could impact their lives.

Our vision is a world where people are free from the fear, harm and heartbreak of dementia.

We are the UK’s leading research charity aiming to defeat dementia. We power world-class studies that give us the best chance of beating dementia sooner.

Our pioneering work focuses on prevention, treatment and cure. We are energising a movement across society to support, fund and take part in dementia research. We aim to empower people across all generations through greater understanding of dementia.

The project started as partnership between Alzheimer’s Research UK and a group of staff from the pharmaceutical company Eisai Ltd, who chose to dedicate their time to helping children understand dementia.

Dementia explained has been possible thanks to the generous support of:
