'Exercising twice a week [can also help].'
'Good for You, Good for Your Brain' rolls out in Glasgow shopping centre Buchanan Galleries on 5 June, backed by a national newspaper advertising campaign.
Scottish comedian and chat show host Craig Hill will play on a giant chessboard to highlight the kind of games that can help prevent Alzheimer's.
Shoppers at Buchanan Galleries will be invited to wear pedometers and record 100 miles of walking. The figure represents 100 years since the first diagnosis of Alzheimer's disease.
Leaflets, a website and promotional activity will detail a telephone number for information on preventative measures.
Direct marketing firm WWAV Rapp Collins' Edinburgh office is running the ad campaign. Client services manager Karen Andre leads the account.
The charity is also in talks with Scottish supermarket Scotmid about promotional tie-ins for the drive.
