Together we have the power to defeat dementia

Your donation

Support the orange appeal

Your gift today could help us develop treatments quicker.

The brain of a person with Alzheimer’s weighs around 140g less than a healthy brain; about the weight of an orange. This physical damage shows that dementia is caused by diseases that can – and will – be beaten through research.

Imagine a future where people are free from the fear, harm and heartbreak of dementia.

Your donation today can make that wish a reality.

The difference your donations make

Thanks to donations, our scientists have been behind some of the biggest breakthroughs in dementia research. Their pioneering work is bringing us closer to a future without dementia.

We currently support 125 research projects across the UK and progress is being made continually. For example, Alzheimer's Research UK scientists discovered two new genes related to Alzheimer's: the first such breakthrough in 15 years. Over 16,000 people took part in the huge study. The findings were reported around the world and hailed by TIME magazine as one of the most important medical discoveries of the year.
