Dame Dame Judi Dench, Stephen Fry, Brian Cox and Dame Dame Harriet Walter are backing Alzheimer's Research UK’s latest petition, calling on the government to 'deliver its election promise to double investment in dementia research', after it failed to acknowledge its pledge to support dementia research in the recent Spending Review.

Alzheimer’s Research UK ambassador and Golden Globe winner, Brian Cox, said 'I was forced to witness dementia take hold of both my brother-in-law and my own brother, while knowing nothing could be done to stop it. I don’t want other families to go through this heartbreak, so I’m passionate about doing all I can to help the search for life-changing treatments... Sign Alzheimer's Research UK’s petition today and tell this government we cannot wait any longer. Dementia is not slowing down, so we must speed up our efforts'.
