The charity, which has previously used specialist fundraising agencies to create its communications, has contacted a number of DM agencies about the business.
ART is the UK's largest dedicated financier of dementia research, with more than £14m in active grants.
Earlier this year, it launched its first TV fundraising campaign, created by Domain. The two DRTV ads, "lost" and "lab", demonstrated the urgent need for increased fundraising for research by showing the impact dementia can have on families.
Domain also created an appeal called Memories Matter to encourage supporters to get more involved in the fight against dementia.
The campaign, which included direct mail and a microsite, asked supporters to submit their favourite memories and make a donation that could one day protect those memories from dementia.
