Comedian, actor and writer Stephen Fry has teamed up with Alzheimer's Research UK to narrate its new Christmas advert, titled Santa Forgot.

The animated advert raises awareness about how Alzheimer's can affect anyone, even Santa, and shows a young girl travelling to the North Pole to help. Fry commented 'From the moment I was told about Santa Forgot I wanted to lend my support - it is an inspiring and beautiful take on a Christmas tale. I urge people up and down the country to get behind the campaign so we can fuel the fight against dementia and take a step forward to making it history'.
