We are Tika and Darragh, dementia scientists at the Centre for Medicines Discovery, University of Oxford.

We have challenged ourselves to run the Paris Marathon in April on behalf of ARUK to raise much-needed funds for Alzheimer's Disease and dementia research.

Every 3 minutes dementia steals a happily ever after. Research is our only chance of changing the ending for people affected by dementia.

We are the UK's leading dementia research charity. We exist for a cure.

Your donation helps our scientists and researchers find new ways to diagnose dementia, develop new treatments and find a cure for dementia.
